This CVE scan report contains a security report with all open CVEs. To get the list of actionable security issues, find the "latest" tag, click the vulnerability report link under the corresponding "Security scan" field and then select the "Only show fixable" filter on the next page.

Non-root container images add an extra layer of security and are generally recommended for production environments. However, because they run as a non-root user, privileged tasks are typically off-limits. Learn more about non-root containers in our docs.

Subscribe to project updates by watching the bitnami/couchdb GitHub repo.

The recommended way to get the Bitnami CouchDB Docker Image is to pull the prebuilt image from the Docker Hub Registry.

$ docker pull bitnami/couchdb:latest

To use a specific version, you can pull a versioned tag. You can view the list of available versions in the Docker Hub Registry.

$ docker pull bitnami/couchdb:[TAG]

If you wish, you can also build the image yourself.

$ docker build -t bitnami/couchdb:latest 'https://github.com/bitnami/bitnami-docker-couchdb.git#master:3/debian-10'

If you remove the container all your data will be lost, and the next time you run the image the database will be reinitialized. To avoid this loss of data, you should mount a volume that will persist even after the container is removed.

For persistence you should mount a directory at the /bitnami path. If the mounted directory is empty, it will be initialized on the first run.

$ docker run \
    -v /path/to/couchdb-persistence:/bitnami/couchdb \
    bitnami/couchdb:latest

You can also do this with a minor change to the docker-compose.yml file present in this repository:

couchdb:
  ...
  volumes:
    - /path/to/couchdb-persistence:/bitnami/couchdb
  ...

NOTE: As this is a non-root container, the mounted files and directories must have the proper permissions for the UID 1001.

Using Docker container networking, a different server running inside a container can easily be accessed by your application containers and vice-versa.

Containers attached to the same network can communicate with each other using the container name as the hostname.

$ docker network create couchdb-network --driver bridge

Use the --network <NETWORK> argument to the docker run command to attach the container to the couchdb-network network.

$ docker run --name couchdb-node1 --network couchdb-network bitnami/couchdb:latest

We can launch another containers using the same flag (--network NETWORK) in the docker run command. If you also set a name to your container, you will be able to use it as hostname in your network.

The configuration can easily be setup in the Bitnami CouchDB Docker image by using the following environment variables:

• COUCHDB_NODENAME: A server alias for clustering support. Default: [email protected]
• COUCHDB_PORT_NUMBER: Standard port for all HTTP API requests. Default: 5984
• COUCHDB_CLUSTER_PORT_NUMBER: Port for cluster communication. Default: 9100
• COUCHDB_BIND_ADDRESS: Address binding for the standard port. Default: 0.0.0.0
• COUCHDB_CREATE_DATABASES: If set to yes, during the first initialization of the container the system databases will be created. Default: yes
• COUCHDB_USER: The username of the administrator user when authentication is enabled. Default: admin
• COUCHDB_PASSWORD: The password to use for login with the admin user set in the COUCHDB_USER environment variable. Default: couchdb
• COUCHDB_PASSWORD_FILE: Path to a file that contains the password for the custom user set in the COUCHDB_USER environment variable. This will override the value specified in COUCHDB_PASSWORD. No defaults.
• COUCHDB_SECRET: The secret token for Proxy and Cookie Authentication. If it is not specified, it will be randomly generated. No defaults.
• COUCHDB_SECRET_FILE: Path to a file that contains the contents of the secret parameter for CouchDB. This will override the value specified in COUCHDB_SECRET. No defaults.

You can specify these environment variables in the docker run command:

$ docker run --name couchdb -e COUCHDB_PORT_NUMBER=7777 bitnami/couchdb:latest

or by modifying the docker-compose.yml file present in this repository:

services:
  couchdb:
  ...
    environment:
      - COUCHDB_PORT_NUMBER=7777
  ...

If you want to provide more specific configuration options to CouchDB, you can always mount your own configuration files under /opt/bitnami/couchdb/etc/. You can either add new ones under ./local.d or override the existing ones.

To understand the precedence of the different configuration files, please check how CouchDB reads them.

Run the CouchDB image, mounting a directory from your host.

$ docker run --name couchdb -v /path/to/config/dir:/opt/bitnami/couchdb/etc bitnami/couchdb:latest

or using Docker Compose:

services:
  couchdb:
  ...
    volumes:
      - /path/to/config/dir:/opt/bitnami/couchdb/etc/
  ...

Edit the configuration on your host using your favorite editor.

vi /path/to/config/file/10-custom.ini

After changing the configuration, restart your CouchDB container for changes to take effect.

$ docker restart couchdb

or using Docker Compose:

$ docker-compose restart couchdb

In order to configure CouchDB as a cluster of nodes, please make sure you set proper values for the following environment variables:

• COUCHDB_NODENAME. A server alias. It should be different on each container.
• COUCHDB_CLUSTER_PORT_NUMBER: Port for cluster communication. Default: 9100
• COUCHDB_CREATE_DATABASES: Whether to create the system databases or not. You should only set it to yes in one of the nodes. Default: yes

The Bitnami CouchDB Docker image sends the container logs to stdout. To view the logs:

$ docker logs couchdb

You can configure the containers logging driver using the --log-driver option if you wish to consume the container logs differently. In the default configuration docker uses the json-file driver.

The Bitnami CouchDB Docker image is built using a Dockerfile with the structure below:

FROM bitnami/minideb
...
# Install required system packages and dependencies
RUN install_packages xxx yyy zzz
RUN . /opt/bitnami/scripts/libcomponent.sh && component_unpack "couchdb" "a.b.c-0"
...
COPY rootfs /
RUN /opt/bitnami/scripts/couchdb/postunpack.sh
...
ENV BITNAMI_APP_NAME="couchdb" ...
VOLUME [ "/bitnami/couchdb" ]
EXPOSE 5984 4369 9100
USER 1001
...
ENTRYPOINT [ "/opt/bitnami/scripts/couchdb/entrypoint.sh" ]
CMD [ "/opt/bitnami/scripts/couchdb/run.sh" ]

The Dockerfile has several sections related to:

• Components installation
• Components static configuration
• Environment variables
• Ports to be exposed
• User
  • Note that once the user is set to 1001, privileged commands cannot be executed any longer.
• Entrypoint and command
  • Take into account that these actions are not executed until the container is started.

The Bitnami CouchDB Docker image is designed to be extended so it can be used as the base image where you can add custom configuration files or other packages.

Note: Read the previous section to understand the Dockerfile structure before extending this image.

Before extending this image, please note there are certain configuration settings you can modify using the original image:

• Settings that can be adapted using environment variables. For instance, you can change the port used by CouchDB by setting the environment variable COUCHDB_PORT_NUMBER.
• Replacing or adding your own configuration files.

If your desired customizations cannot be covered using the methods mentioned above, extend the image. To do so, create your own image using a Dockerfile with the format below:

FROM bitnami/couchdb
## Put your customizations below
...

Here is an example of extending the image with the following modifications:

• Install the vim editor
• Modify the port used by CouchDB
• Change the user that runs the container

FROM bitnami/couchdb
LABEL maintainer "Bitnami <[email protected]>"

## Change user to perform privileged actions
USER 0
## Install 'vim'
RUN install_packages vim
## Revert to the original non-root user
USER 1001

## Modify the ports used by NGINX by default
ENV COUCHDB_PORT_NUMBER=1234 # It is also possible to change this environment variable at runtime
EXPOSE 1234 4369

## Modify the default container user
USER 1002

Based on the extended image, you can use a Docker Compose file like the one below to add other features:

• Add a custom configuration file

version: '2'
services:
  couchdb:
    build: .
    environment:
      - COUCHDB_PASSWORD=couchdb
    ports:
      - '1234:1234'
      - '4369:4369'
    volumes:
      - couchdb_data:/bitnami/couchdb
      - /path/to/config/file/10-custom.ini:/opt/bitnami/couchdb/etc/local.d/10-custom.ini
volumes:
  couchdb_data:
    driver: local

Bitnami provides up-to-date versions of CouchDB, including security patches, soon after they are made upstream. We recommend that you follow these steps to upgrade your container.
