Rancher-Status-Page:

• The purpose of this repo is to house a container that runs a simple NodeJS application in order to display a nice, simple UI showing the latest deployed DockerHub tags per stack / container in each respective environment you've created in your Rancher cluster.
• The NodeJS simply executes a shell script (data.sh), and serves up a dynamically generated index page (index.html).
• This container must run in rancher in order for the curl calls against the Rancher metadata API to work.
• This is important, because it allows to get a high-level view of currently deployed docker tags for each respective stack.

Notes:

• This job requires that the container runs in a Rancher environment in order to access the Rancher-Metadata API.

• Containers that wish to use the status page must implement the stack.name label in their rancher-compose:

• Be sure to export DOCKER_TAG for your desired docker tag from DockerHub prior to submitting rancher-compose.yml.

    labels:
      io.rancher.container.dns: "true"
      io.rancher.stack.name: "srflaxu40/rancher_status_page:${DOCKER_TAG}"
  

• To use the rancher-metadata API, you must enable the following label in your container's rancher-compose file:

    io.rancher.container.dns: true
  

Build:

• docker build --no-cache -t rancher-status-page

Run (this won't hit the Rancher-metadata API):

• docker-compose -f docker-compose.yml up -d web

Run in rancher (requires changing values in rancher_env.sh:

• source rancher_env.sh
• rancher-compose --verbose -f rancher-compose.yml -p rancher-status up --upgrade --confirm-upgrade --pull -d
  • After running the above command, go to port 20040 of your rancher instance or host, and see what tags you have deployed for each stack / container.
