Welcome to the Earth Analytics Environment Repository! Here you will find a conda envt that can be installed on your computer using a .yaml file. You will also find a docker image that can be used to actually run the environment in a containerized environment.

To begin, install git and conda for Python 3.x (we suggest 3.6).

Installing git: https://git-scm.com/book/en/v2/Getting-Started-Installing-Git

Installing conda: https://www.anaconda.com/

We recommend installing geo-related dependencies with conda-forge. We have created a custom yaml list with all of the dependencies that you will need to run the lessons in this course. Follow these steps below to get your environment ready.

About Conda Environments: https://conda.io/docs/user-guide/tasks/manage-environments.html

An environment for conda has been created specifically for this course. To load it, run:

conda env create -f environment.yml

• Note that it takes a bit of time to run this setup
• Also note that for the code above to work, you need to be in the directory where the environment.yml file lives (ex: cd earth-analytics-python-env).

To update this environment from a yaml file use: conda env update -f environment.yml

To manage your conda environments, use the following commands:

conda info --envs

Conda 4.6 and later versions (all operating systems):

conda activate earth-analytics-python

Conda versions prior to 4.6:

On Mac or Linux:

source activate earth-analytics-python

On Windows:

activate earth-analytics-python

The environment name is earth-analytics-python as defined in the environment.yml file.

To run a docker container you need to do the following:

1. Install docker and make sure it is running.

2. Build the docker image on your compute locally. Be patient - this will take a bit of time. Run the following lines to build the docker image locally:

cd earth-analytics-python-env
docker build -t earthlab/earth-analytics-python-env .
docker run -it -p 8888:8888 earthlab/earth-analytics-python-env

3. Run the image.

To run your earth-analytics image, use the following code:

docker run --hostname localhost -it -p 8888:8888 earthlab/earth-analytics-python-env

NOTE: earthlab/earth-analytics-python-env is the name of this image as built above. To view all images on your computer, type docker images --all

One you run your image, you will be given a URL at the command line. Paste that puppy into your browser to run jupyter with the earth analytics environment installed!!

If you wish to update the earth analytics environment, do the following.

1. make a PR with changes to master
2. think about your changes - don't do silly things or break things :)
3. merge the PR into the master branch
4. Check & wait till Dockerhub has built the image for the merging of the PR you can see builds in progress, here
5. Finally, once the build is complete you can then you can update hub-ops repo with the newly tagged image.

If the update the earthpy package, you must specify the commit number that you wish to build earthpy against. This will ensure that the docker image automagically rebuilds using the latest version of earthpy

like this: - git+https://github.com/earthlab/earthpy.git@283683affac9e46b1690c7913ebd2621c82ba43a

This PR should kick off a rebuild of the docker image. But that docker image will not be usable until it's built off of the master branch.

NOTE 2: The DockerHub build actually takes forever and ever. So it's best to check out the build status rather than assuming it's built.
