The Galaxy Docker Image is an easy distributable full-fledged Galaxy installation, that can be used for testing, teaching and presenting new tools and features.
One of the main goals is to make the access to entire tool suites as easy as possible. Usually, this includes the setup of a public available web-service that needs to be maintained, or that the Tool-user needs to either setup a Galaxy Server by its own or to have Admin access to a local Galaxy server. With docker, tool developers can create their own Image with all dependencies and the user only needs to run it within docker.
The Image is based on Ubuntu 14.04 LTS and all recommended Galaxy requirements are installed. The following chart should illustrate the Docker image hierarchy we have build to make is as easy as possible to build on different layers of our stack and create many exciting Galaxy flavors.

Usage [toc]
This chapter explains how to launch the container manually. An ansible playbook that launches the container automatically is available here.
At first you need to install docker. Please follow the very good instructions from the Docker project.
After the successful installation, all you need to do is:
docker run -d -p 8080:80 -p 8021:21 -p 8022:22 bgruening/galaxy-stable
I will shortly explain the meaning of all the parameters. For a more detailed description please consult the docker manual, it's really worth reading.
Let's start:
-
docker run
will run the Image/Container for you.In case you do not have the Container stored locally, docker will download it for you.
-
-p 8080:80
will make the port 80 (inside of the container) available on port 8080 on your host. Same holds for port 8021 and 8022, that can be used to transfer data via the FTP or SFTP protocol, respectively.Inside the container a nginx Webserver is running on port 80 and that port can be bound to a local port on your host computer. With this parameter you can access your Galaxy instance via
http://localhost:8080
immediately after executing the command above. If you work with the Docker Toolbox on Mac or Windows, you need to connect to the machine generated by 'Docker Quickstart'. You get its IP address fromdocker-machine ls
or from the first line in the terminal, e.g.:docker is configured to use the default machine with IP 192.168.99.100
. -
bgruening/galaxy-stable
is the Image/Container name, that directs docker to the correct path in the docker index. -
-d
will start the docker container in daemon mode.
For an interactive session, you can execute:
docker run -i -t -p 8080:80 \
bgruening/galaxy-stable \
/bin/bash
and run the startup
script by yourself, to start PostgreSQL, nginx and Galaxy.
Docker images are "read-only", all your changes inside one session will be lost after restart. This mode is useful to present Galaxy to your colleagues or to run workshops with it. To install Tool Shed repositories or to save your data you need to export the calculated data to the host computer.
Fortunately, this is as easy as:
docker run -d -p 8080:80 \
-v /home/user/galaxy_storage/:/export/ \
bgruening/galaxy-stable
With the additional -v /home/user/galaxy_storage/:/export/
parameter, Docker will mount the local folder /home/user/galaxy_storage
into the Container under /export/
. A startup.sh
script, that is usually starting nginx, PostgreSQL and Galaxy, will recognize the export directory with one of the following outcomes:
- In case of an empty
/export/
directory, it will move the PostgreSQL database, the Galaxy database directory, Shed Tools and Tool Dependencies and various config scripts to /export/ and symlink back to the original location. - In case of a non-empty
/export/
, for example if you continue a previous session within the same folder, nothing will be moved, but the symlinks will be created.
This enables you to have different export folders for different sessions - means real separation of your different projects.
You can also collect and store /export/
data of Galaxy instances in a dedicated docker Data volume Container created by:
docker create -v /export \
--name galaxy-store \
bgruening/galaxy-stable \
/bin/true
To mount this data volume in a Galaxy container, use the --volumes-from
parameter:
docker run -d -p 8080:80 \
--volumes-from galaxy-store \
bgruening/galaxy-stable
This also allows for data separation, but keeps everything encapsulated within the docker engine (e.g. on OS X within your $HOME/.docker
folder - easy to backup, archive and restore. This approach, albeit at the expense of disk space, avoids the problems with permissions reported for data export on non-Linux hosts.
Upgrading images [toc]
We will release a new version of this image concurrent with every new Galaxy release. For upgrading an image to a new version we have assembled a few hints for you. Please, take in account that upgrading may vary depending on your Galaxy installation, and the changes in new versions. Use this example carefully!
- Create a test instance with only the database and configuration files. This will allow testing to ensure that things run but won't require copying all of the data.
- New unmodified configuration files are always stored in a hidden directory called
.distribution_config
. Use this folder to diff your configurations with the new configuration files shipped with Galaxy. This prevents needing to go through the change log files to find out which new files were added or which new features you can activate. - Note that copying database and datasets can be expensive if you have many GB of data.
- Download newer version of the Galaxy image
$ sudo docker pull bgruening/galaxy-stable
- Stop and rename the current galaxy container
$ sudo docker stop galaxy-instance
$ sudo docker rename galaxy-instance galaxy-instance-old
- Rename the data directory (the one that is mounted to /export in the docker)
$ sudo mv /data/galaxy-data /data/galaxy-data-old
- Run a new Galaxy container using newer image and wait while Galaxy generates the default content for /export
$ sudo docker run -p 8080:80 -v /data/galaxy-data:/export --name galaxy-instance bgruening/galaxy-stable
- Stop the Galaxy container
$ sudo docker stop galaxy-instance
- Replace the content of the postgres database by the old db data
$ sudo rm -r /data/galaxy-data/postgresql/
$ sudo rsync -var /data/galaxy-data-old/postgresql/ /data/galaxy-data/postgresql/
- Use diff to find changes in the config files (only if you changed any config file).
$ cd /data/galaxy-data/.distribution_config
$ for f in *; do echo $f; diff $f ../../galaxy-data-old/galaxy-central/config/$f; read; done
- Copy all the users' datasets to the new instance
$ sudo rsync -var /data/galaxy-data-old/galaxy-central/database/files/* /data/galaxy-data/galaxy-central/da
tabase/files/
- Copy all the installed tools
$ sudo rsync -var /data/galaxy-data-old/tool_deps/* /data/galaxy-data/tool_deps/
$ sudo rsync -var /data/galaxy-data-old/shed_tools/* /data/galaxy-data/shed_tools/
- Copy the welcome page and all its files.
$ sudo rsync -var /data/galaxy-data-old/welcome* /data/galaxy-data/
- Create an auxiliary docker in interactive mode and upgrade the database.
$ sudo docker run -it --rm -v /data/galaxy-data:/export bgruening/galaxy-stable /bin/bash
# Startup all processes
> startup &
#Upgrade the database to the most recent version
> sh manage_db.sh upgrade
#Logout
> exit
- Start the docker and test
$ sudo docker start galaxy-instance
- Clean the old container and image
Enabling Interactive Environments in Galaxy [toc]
Interactive Environments (IE) are sophisticated ways to extend Galaxy with powerful services, like Jupyter, in a secure and reproducible way.
For this we need to be able to launch Docker containers inside our Galaxy Docker container. At least docker 1.3 is needed on the host system.
docker run -d -p 8080:80 -p 8021:21 -p 8800:8800 \
--privileged=true \
-v /home/user/galaxy_storage/:/export/ \
bgruening/galaxy-stable
The port 8800 is the proxy port that is used to handle Interactive Environments. --privileged
is needed to start docker containers inside docker. If your IE does not open, please make sure you open your Galaxy instance with your hostname or a FQDN, but not with localhost or 127.0.0.1.
Using passive mode FTP or SFTP [toc]
By default, FTP servers running inside of docker containers are not accessible via passive mode FTP, due to not being able to expose extra ports. To circumvent this, you can use the --net=host
option to allow Docker to directly open ports on the host server:
docker run -d \
--net=host \
-v /home/user/galaxy_storage/:/export/ \
bgruening/galaxy-stable
Note that there is no need to specifically bind individual ports (e.g., -p 80:80
) if you use --net
.
An alternative to FTP and it's shortcomings it to use the SFTP protocol via port 22. Start your Galaxy container with a port binding to 22.
docker run -i -t -p 8080:80 -p 8022:22 \
-v /home/user/galaxy_storage/:/export/ \
bgruening/galaxy-stable
And use for example Filezilla or the sftp
program to transfer data:
sftp -v -P 8022 -o [email protected] localhost <<< $'put <YOUR FILE HERE>'
Using Parent docker [toc]
On some linux distributions, Docker-In-Docker can run into issues (such as running out of loopback interfaces). If this is an issue, you can use a 'legacy' mode that use a docker socket for the parent docker installation mounted inside the container. To engage, set the environmental variable DOCKER_PARENT
docker run -p 8080:80 -p 8021:21 -p 8800:8800 \
--privileged=true -e DOCKER_PARENT=True \
-v /var/run/docker.sock:/var/run/docker.sock \
-v /home/user/galaxy_storage/:/export/ \
bgruening/galaxy-stable
Galaxy Report Webapp [toc]
For admins wishing to have more information on the status of a galaxy instance, the Galaxy Report Webapp is served on http://localhost:8080/reports
. As default this site is password protected with admin:admin
. You can change this by providing a reports_htpasswd
file in /home/user/galaxy_storage/
.
You can disable the Report Webapp entirely by providing the environment variable NONUSE
during container startup.
docker run -p 8080:80 \
-e "NONUSE=reports" \
bgruening/galaxy-stable
Galaxy's config settings [toc]
Every Galaxy configuration parameter in config/galaxy.ini
can be overwritten by passing an environment variable to the docker run
command during startup. The name of the environment variable has to be:
GALAXY_CONFIG
+ the_original_parameter_name_in_capital_letters
For example, you can set the Galaxy session timeout to 5 minutes by adding -e "GALAXY_CONFIG_SESSION_DURATION=5"
to the docker run command
by default the admin_users
, master_api_key
and the brand
variable it set to:
[email protected]
GALAXY_CONFIG_MASTER_API_KEY=HSNiugRFvgT574F43jZ7N9F3
GALAXY_CONFIG_BRAND="Galaxy Docker Build"
You can and should overwrite these during launching your container:
docker run -p 8080:80 \
-e "[email protected]" \
-e "GALAXY_CONFIG_MASTER_API_KEY=83D4jaba7330aDKHkakjGa937" \
-e "GALAXY_CONFIG_BRAND='My own Galaxy flavour'" \
bgruening/galaxy-stable
Note that if you would like to run any of the cleanup scripts, you will need to add the following to /export/galaxy-central/config/galaxy.ini
:
database_connection = postgresql://galaxy:galaxy@localhost:5432/galaxy
file_path = /export/galaxy-central/database/files
Configuring Galaxy's behind a proxy [toc]
If your Galaxy docker instance is running behind an HTTP proxy server, and if you're accessing it with a specific path prefix (e.g. http://www.example.org/some/prefix/), you need to make Galaxy aware of it. There is an environment variable available to do so:
PROXY_PREFIX=/some/prefix
You can and should overwrite these during launching your container:
docker run -p 8080:80 \
-e "PROXY_PREFIX=/some/prefix" \
bgruening/galaxy-stable
On-demand reference data with CVMFS [toc]
By default, Galaxy instances launched with this image will have on-demand access to approximately 3TB of
reference genomes and indexes. These are the same reference data available on the main Galaxy server.
This is achieved by connecting to Galaxy's CernVM filesystem (CVMFS) at data.galaxyproject.org
repository,
which is geographically distributed among numerous servers.
The CVMFS capability doesn't add to the size of the Docker image, but when running, CVMFS maintains
a cache to keep the most recently used data on the local disk.
Note: for CVMFS directories to be mounted-on-demand with autofs
, you must launch Docker as --privileged
Personalize your Galaxy [toc]
The Galaxy welcome screen can be changed by providing a welcome.html
page in /home/user/galaxy_storage/
. All files starting with welcome
will be copied during startup and served as introduction page. If you want to include images or other media, name them welcome_*
and link them relative to your welcome.html
(example).
Deactivating services [toc]
Non-essential services can be deactivated during startup. Set the environment variable NONUSE
to a comma separated list of services. Currently, nodejs
, postgres
, proftp
, reports
, slurmd
and slurmctld
are supported.
docker run -d -p 8080:80 -p 9002:9002 \
-e "NONUSE=nodejs,proftp,reports,slurmd,slurmctld" \
bgruening/galaxy-stable
A graphical user interface, to start and stop your services, is available on port 9002
if you run your container like above.
Restarting Galaxy [toc]
If you want to restart Galaxy without restarting the entire Galaxy container you can use docker exec
(docker > 1.3).
docker exec <container name> supervisorctl restart galaxy:
In addition you can start/stop every supervisord process using a web interface on port 9002
. Start your container with:
docker run -p 9002:9002 bgruening/galaxy-stable
Advanced Logging [toc]
You can set the environment variable $GALAXY_LOGGING to FULL to access all logs from supervisor. For example start your container with:
docker run -d -p 8080:80 -p 8021:21 \
-e "GALAXY_LOGGING=full" \
bgruening/galaxy-stable
Then, you can access the supervisord web interface on port 9002
and get access to log files. To do so, start your container with:
docker run -d -p 8080:80 -p 8021:21 -p 9002:9002 \
-e "GALAXY_LOGGING=full" \
bgruening/galaxy-stable
Alternatively, you can access the container directly using the following command:
docker exec -it <container name> bash
Once connected to the container, log files are available in /home/galaxy/logs
.
A volume can also be used to map this directory to one external to the container - for instance if logs need to be persisted for auditing reasons (security, debugging, performance testing, etc...).:
mkdir gx_logs
docker run -d -p 8080:80 -p 8021:21 -e "GALAXY_LOGGING=full" -v `pwd`/gx_logs:/home/galaxy/logs bgruening/galaxy-stable
Running on an external cluster (DRM) [toc]
Basic setup for the filesystem [toc]
The easiest way is to create a /export
mount point on the cluster and mount the container with /export:/export
.
The docker container sets up all its files on the /export directory, but this directory may not exist on the cluster filesystem. This can be solved with symbolic links on the cluster filesystem but it can also be solved within the container itself.
In this example configuration the cluster file system has a directory /cluster_storage/galaxy
which is accessible for the galaxy user in the container (UID 1450) and the user starting the container.
The container should be started with the following settings configured:
docker run -d -p 8080:80 -p 8021:21 \
-v /cluster_storage/galaxy/galaxy_export:/export \ # This makes sure all galaxy files are on the cluster filesystem
-v /cluster_storage/galaxy:/cluster_storage/galaxy \ # This ensures the links within the docker container and on the cluster fs are the same
# The following settings make sure that each job is configured with the paths on the cluster fs instead of /export
-e GALAXY_CONFIG_TOOL_DEPENDENCY_DIR="/cluster_storage/galaxy/galaxy_export/tool_deps" \
-e GALAXY_CONFIG_TOOL_DEPENDENCY_CACHE_DIR="/cluster_storage/galaxy/galaxy_export/tool_deps/_cache" \
-e GALAXY_CONFIG_FILE_PATH="/cluster_storage/galaxy/galaxy_export/galaxy-central/database/files" \
-e GALAXY_CONFIG_TOOL_PATH="/cluster_storage/galaxy/galaxy_export/galaxy-central/tools" \
-e GALAXY_CONFIG_TOOL_DATA_PATH="/cluster_storage/galaxy/galaxy_export/galaxy-central/tool-data" \
-e GALAXY_CONFIG_SHED_TOOL_DATA_PATH="/cluster_storage/galaxy/galaxy_export/galaxy-central/tool-data" \
# The following settings are for directories that can be anywhere on the cluster fs.
GALAXY_CONFIG_JOB_WORKING_DIRECTORY="/cluster_storage/galaxy/galaxy_export/galaxy-central/database/job_working_directory" \ #IMPORTANT: needs to be created manually. Can also be placed elsewhere, but is originally located here
-e GALAXY_CONFIG_NEW_FILE_PATH="/cluster_storage/galaxy/tmp" \ # IMPORTANT: needs to be created manually. This needs to be writable by UID=1450 and have its flippy bit set (chmod 1777 for world-writable with flippy bit)
-e GALAXY_CONFIG_CLUSTER_FILES_DIRECTORY="/cluster_storage/galaxy/job_scripts" \ # Job scripts and stdout and stderr will be written here.
-e GALAXY_CONFIG_OUTPUTS_TO_WORKING_DIRECTORY=False \ # Writes Job scripts, stdout and stderr to job_working_directory.
-e GALAXY_CONFIG_RETRY_JOB_OUTPUT_COLLECTION=5 \ #IF your cluster fs uses nfs this may introduce latency. You can set galaxy to retry if a job output is not yet created.
# Conda settings. IMPORTANT!
-e GALAXY_CONFIG_CONDA_PREFIX="/cluster_storage/galaxy/_conda" \ # Can be anywhere EXCEPT cluster_storage/galaxy/galaxy_export!
# Conda uses $PWD to determine where the virtual environment is. If placed inside the export directory conda will determine $PWD to be a subirectory of the /export folder which does not exist on the cluster!
-e GALAXY_CONFIG_CONDA_AUTO_INIT=True # When the necessary environment can not be found a new one will automatically be created
Setting up a python virtual environment on the cluster [toc]
The python environment in the container is not accessible from the cluster. So it needs to be created beforehand.
In this example configuration the python virtual environment is created on /cluster_storage/galaxy/galaxy_venv
and the export folder on /cluster_storage/galaxy/galaxy_export
. To create the virtual environment:
- Create the virtual environment
virtualenv /cluster_storage/galaxy/galaxy_venv
- Activate the virtual environment
source /cluster_storage/galaxy/galaxy_venv/bin/activate
- Install the galaxy requirements
pip install --index-url https://wheels.galaxyproject.org/simple --only-binary all -r /cluster_storage/galaxy/galaxy-central//lib/galaxy/dependencies/pinned-requirements.txt
- Make sure to upgrade the environment with the new requirements when a new version of galaxy is released.
To make the python environment usable for the cluster. Create your custom job_conf.xml
file and put it in /cluster_storage/galaxy/galaxy_export/galaxy-central/config
.
In the destination section the following code should be added:
<destinations default="cluster">
<destination id="cluster" runner="your_cluster_runner">
<env file="/cluster_storage/galaxy/galaxy_venv/bin/activate"/>
<env id="GALAXY_ROOT_DIR">/cluster_storage/galaxy/galaxy_export/galaxy-central</env>
<env id="GALAXY_LIB">/cluster_storage/galaxy/galaxy_export/galaxy-central/lib</env>
<env id="PYTHONPATH">/cluster_storage/galaxy/galaxy_export/galaxy-central/lib</env>
<param id="embed_metadata_in_job">True</param>
</destination>
In this way, python tools on the cluster are able to use the galaxy libraries.
More information can be found here and here.
Using an external Slurm cluster [toc]
It is often convenient to configure Galaxy to use a high-performance cluster for running jobs. To do so, two files are required:
- munge.key
- slurm.conf
These files from the cluster must be copied to the /export
mount point (i.e., /cluster_storage/galaxy/galaxy_export/
on the host if using below command) accessible to Galaxy before starting the container. This must be done regardless of which Slurm daemons are running within Docker. At start, symbolic links will be created to these files to /etc
within the container, allowing the various Slurm functions to communicate properly with your cluster. In such cases, there's no reason to run slurmctld
, the Slurm controller daemon, from within Docker, so specify -e "NONUSE=slurmctld"
. Unless you would like to also use Slurm (rather than the local job runner) to run jobs within the Docker container, then alternatively specify -e "NONUSE=slurmctld,slurmd"
.
Importantly, Slurm relies on a shared filesystem between the Docker container and the execution nodes. To allow things to function correctly, checkout the basic filesystem setup above.
A brief note is in order regarding the version of Slurm installed. This Docker image uses Ubuntu 14.04 as its base image. The version of Slurm in the Ubuntu 14.04 repository is 2.6.5 and that is what is installed in this image. If your cluster is using an incompatible version of Slurm then you will likely need to modify this Docker image.
The following is an example for how to specify a destination in job_conf.xml
that uses a custom partition ("work", rather than "debug") and 4 cores rather than 1:
<destination id="slurm4threads" runner="slurm">
<param id="embed_metadata_in_job">False</param>
<param id="nativeSpecification">-p work -n 4</param>
</destination>
The usage of -n
can be confusing. Note that it will specify the number of cores, not the number of tasks (i.e., it's not equivalent to srun -n 4
).
Using an external Grid Engine cluster [toc]
Set up the filesystem on the cluster as mentioned above. To use Grid Engine (Sun Grid Engine, Open Grid Scheduler), one configuration file and an environment variable are required:
- create an
act_qmaster
file in the /export folder.
- In act_qmaster is something like this.
YOUR_GRIDENGINE_MASTER_HOST
- this file will automatically be installed in the container's
/var/lib/gridengine
folder.
- set the environment variable
SGE_ROOT
- By default
-e SGE_ROOT=/var/lib/gridengine
- Make sure that YOUR_GRIDENGINE_MASTER_HOST can be pinged from the docker container. If this is not the case you can put the qmaster's hostname and ip in the containers
/etc/hosts
Your Grid Engine needs to accept job submissions from inside the container. If your container is already on a host that can submit jobs, set the hostname of the container to be exactly the same as the host. (The hostname can be changed by using the --hostname flag when starting the container).
Alternatively, you can add the container's hostname (default=galaxy-docker) to the /etc/hosts file on the gridengine head node. And setting the container's hostname as a submit host.
Tips for Running Jobs Outside the Container [toc]
In its default state Galaxy assumes both the Galaxy source code and various temporary files are available on shared file systems across the cluster. When using Condor or SLURM (as described above) to run jobs outside of the Docker container one can take steps to mitigate these assumptions.
The embed_metadata_in_job
option on job destinations in job_conf.xml
forces Galaxy collect metadata inside the container instead of on the
cluster:
<param id="embed_metadata_in_job">False</param>
This has performance implications and may not scale as well as performing these calculations on the remote cluster - but this should not be a problem for most Galaxy instances.
Enable Galaxy to use BioContainers (Docker) [toc]
This is a very cool feature where Galaxy automatically detects that your tool has an associated docker image, pulls it and runs it for you. These images (when available) have been generated using mulled. To test, install the IUC bedtools from the toolshed. When you try to execute ClusterBed for example. You may get a missing dependancy error for bedtools. But bedtools has an associated docker image on quay.io. Now configure Galaxy as follows:
- Add this environment variable to
docker run
:-e GALAXY_CONFIG_ENABLE_BETA_MULLED_CONTAINERS=True
- In
job_conf.xml
configure a Docker enabled destination as follows:
<destination id="docker_local" runner="local">
<param id="docker_enabled">true</param>
<param id="docker_volumes">$galaxy_root:ro,$galaxy_root/database/tmp:rw,$tool_directory:ro,$job_directory:ro,$working_directory:rw,$default_file_path:rw</param>
<param id="docker_sudo">false</param>
</destination>
When you execute the tool again, Galaxy will pull the image from Biocontainers (quay.io/biocontainers), run the tool inside of this container to produce the desired output.

HTTPS Support [toc]
It's possible to automatically configure your container with HTTPS, either with certificates of your own or by automatically requesting an HTTPS certificate from Letsencrypt with the following environment variables:
Name | Description |
---|---|
USE_HTTPS |
Set USE_HTTPS=True to set up HTTPS via self-signed certificates. If you have your own certificates, copy them to /export/{server.key,server.crt} . |
USE_HTTPS_LETSENCRYPT |
Set USE_HTTPS_LETSENCRYPT=True to automatically set up HTTPS using Letsencrypt as a certificate authority. (Requires you to also set GALAXY_CONFIG_GALAXY_INFRASTRUCTURE_URL ) Note: only set one of USE_HTTPS and USE_HTTPS_LETSENCRYPT to true. |
GALAXY_CONFIG_GALAXY_INFRASTRUCTURE_URL |
Set GALAXY_CONFIG_GALAXY_INFRASTRUCTURE_URL=<your_domain> so that Letsencrypt can test your that you own the domain you claim to own in order to issue you your HTTPS cert. |
Lite Mode [toc]
The lite mode will only start postgresql and a single Galaxy process, without nginx, uwsgi or any other special feature from the normal mode. In particular there is no support for the export folder or any Magic Environment variables.
docker run -i -t -p 8080:8080 bgruening/galaxy-stable startup_lite
This will also use the standard job_conf.xml.sample_basic
shipped by Galaxy. If you want to use the regular one from the normal mode you can pass -j
to the startup_lite
script.
Extending the Docker Image [toc]
If the desired tools are already included in the Tool Shed, building your own personalised Galaxy docker Image (Galaxy flavour) can be done using the following steps:
- Create a file named
Dockerfile
- Include
FROM bgruening/galaxy-stable
at the top of the file. This means that you use the Galaxy Docker Image as base Image and build your own extensions on top of it. - Supply the list of desired tools in a file (
my_tool_list.yml
below). See this page for the file format requirements. - Execute
docker build -t my-docker-test .
4a. (if behind proxy). Add the ENV http_proxy and https_proxy variables as IPs (to avoid nameserver resolution problems) as in the example below. - Run your container with
docker run -p 8080:80 my-docker-test
- Open your web browser on
http://localhost:8080
For a working example, have a look at these Dockerfiles.

or the RNA-workbench. The RNA-workbench has advanced examples about:
-
populating Galaxy data-libararies
setup-data-libraries -i $GALAXY_ROOT/library_data.yaml -g http://localhost:8080 -u $GALAXY_DEFAULT_ADMIN_USER -p $GALAXY_DEFAULT_ADMIN_PASSWORD
The actual data is references in a YAML file similar this one.
-
installing workflows
workflow-install --workflow_path $GALAXY_HOME/workflows/ -g http://localhost:8080 -u $GALAXY_DEFAULT_ADMIN_USER -p $GALAXY_DEFAULT_ADMIN_PASSWORD
Where all Galaxy workflows needs to be in one directory, here the $GALAXY_HOME/workflows/
.
-
running Galaxy data-managers to create indices or download data
run-data-managers -u [email protected] -p admin -g http://localhost:8080 --config data_manager_rna_seq.yaml
The data-managers can be configured and specified in a YAML file similar to this one.

Integrating non-Tool Shed tools into the container [toc]
We recommend to use the Main Galaxy Tool Shed for all your tools and workflows that you would like to share. In rare situations where you cannot share your tools but still want to include them into your Galaxy Docker instance, please follow the next steps.
-
Get your tools into the container.
Mount your tool directory into the container with a separate
-v /home/user/my_galaxy_tools/:/local_tools
. -
Create a
tool_conf.xml
file for your tools.This should look similar to the main
tool_conf.xml
file, but references your tools from the new directory. In other words a tool entry should look like this<tool file="/local_tools/application_foo/foo.xml" />
. Yourtool_conf.xml
should be available from inside of the container. We assume you have it stored under/local_tools/my_tools.xml
. -
Add the new tool config file to the Galaxy configuration.
To make Galaxy aware of your new tool configuration file you need to add the path to
tool_config_file
, which is by default#tool_config_file = config/tool_conf.xml,config/shed_tool_conf.xml
. You can do this during container start by setting the environment variable-e GALAXY_CONFIG_TOOL_CONFIG_FILE=config/tool_conf.xml.sample,config/shed_tool_conf.xml.sample,/local_tools/my_tools.xml
.
Users & Passwords [toc]
The Galaxy Admin User has the username [email protected]
and the password admin
.
The PostgreSQL username is galaxy
, the password is galaxy
and the database name is galaxy
(I know I was really creative ;)).
If you want to create new users, please make sure to use the /export/
volume. Otherwise your user will be removed after your docker session is finished.
The proftpd server is configured to use the main galaxy PostgreSQL user to access the database and select the username and password. If you want to run the
docker container in production, please do not forget to change the user credentials in /etc/proftpd/proftpd.conf
too.
The Galaxy Report Webapp is htpasswd
protected with username and password set to admin
.
Development [toc]
This repository uses a git submodule to include Ansible roles maintained by the Galaxy project.
You can clone this repository and the Ansible submodule with:
git clone --recursive https://github.com/bgruening/docker-galaxy-stable.git
Updating already existing submodules is possible with:
git submodule update --init --recursive
If you simply want to change the Galaxy repository and/or the Galaxy branch, from which the container is build you can do this with Docker --build-arg
during the docker build
step. For example you can use these parameters during container build:
--build-arg GALAXY_RELEASE=install_workflow_and_tools
--build-arg GALAXY_REPO=https://github.com/manabuishii/galaxy
