⁠Dockerized Wetty for CoreOS CLIs

This image provides a Wetty⁠ terminal with access to the following CoreOS command-line tools:

• docker
• fleetctl
• etcdctl

⁠docker

The Docker CLI requires access to the docker.sock in the host OS in order to communicate with the Docker daemon. To provide access to the docker.sock you need to mount it into the container using the -v flag:

docker run -p 3000:3000 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  centurylink/coreos-cli-wetty

⁠fleetctl

The Fleet CLI communicates with the Etcd API over HTTP. The Etcd endpoint is specified by setting the FLEETCTL_ENDPOINT environment variable. The default value is http://10.1.42.1:4001⁠ (10.1.42.1 is typically the IP address of the docker0 interface in CoreOS) but can be overriden with the -e flag on the docker run command if necessary.

docker run -p 3000:3000 \
  -v /var/run/docker.sock:/var/run/docker.sock \
  -e FLEETCTL_ENDPOINT=http://17.1.0.10:4001 \
  centurylink/coreos-cli-wetty

⁠Wetty

Once the container is running, the Wetty terminal can be accessed by browsing to [http://localhost:3000] (assuming 3000 was the port mapping you chose when starting the container) with your Chrome browser. Login with username term and password term.
