docker/build/go-agent-frontend/README.rst

+Usage
+#####
+
+Start the container with this:
+
+``docker run -d --network=edxgomatic_go-network -e GO_SERVER_URL=https://go-server:8154/go go-agent-frontend:latest``
+
+If you need to start a few GoCD agents together, you can of course use the
+shell to do that. Start a few agents in the background, like this:
+
+``for each in 1 2 3; do docker run -d --link angry_feynman:go-server edx/go-agent-frontend; done``
+
+Getting into the container
+##########################
+
+Sometimes, you need a shell inside the container (to create test repositories,
+etc). docker provides an easy way to do that:
+
+``docker exec -i -t CONTAINER-ID /bin/bash``
+
+To check the agent logs, you can do this:
+
+``docker exec -i -t CONTAINER-ID tail -f /var/log/go-agent/go-agent.log``
+
+Agent Configuration
+###################
+
+The go-agent expects it's configuration to be found at
+``/var/lib/go-agent/config/``. Sharing the configuration between containers is
+done by mounting a volume at this location that contains any configuration
+files necessary.
+
+**Example docker run command:**
+``docker run -ti -v /tmp/go-agent/conf:/var/lib/go-agent/config -e GO_SERVER=gocd.sandbox.edx.org 718d75c467c0 bash``

+Building and Uploading the container to ECS
+###########################################
+
+-  Build and tag the go-agent docker image
+
+   -  Follow the README in the go-agent directory to build and tag for go-agent.
+
+-  Create image
+
+   -  This must be run from the root of the configuration repository
+   -  ``docker build -f docker/build/go-agent-frontend/Dockerfile .``
+   -  or
+   -  ``make docker.test.go-agent-frontend``
+
+-  Log docker in to AWS
+
+   -  Assume the role of the account you wish to log in to
+
+      -  ``source assume_role.sh <account name>``
+
+   -  ``sh -c `aws ecr get-login --region us-east-1```
+
+      -  You might need to remove the ``-e`` option returned by that command in
+         order to successfully login.
+
+-  Tag image
+
+   -  ``docker tag <image_id> ############.dkr.ecr.us-east-1.amazonaws.com/prod-tools-goagent-frontend:latest``
+   -  ``docker tag <image_id> ############.dkr.ecr.us-east-1.amazonaws.com/prod-tools-goagent-frontend:<version_number>``
+
+-  upload:
+
+   -  ``docker push ############.dkr.ecr.us-east-1.amazonaws.com/edx/release-pipeline/prod-tools-goagent-frontend:latest``
+   -  ``docker push ############.dkr.ecr.us-east-1.amazonaws.com/edx/release-pipeline/prod-tools-goagent-frontend:<version_number>``
