go continuous delivery agent

This is a base image for a go cd agent. It only offers a JDK as resource. For adding other resources, a new agent image may extend this image. See Extending the image.

Setting up a docker container

docker build -t softwarecraftsmen/go-cdagent .

Starting a Docker container

docker run -tid --name go-cdagent --hostname go-cdagent \

Extending the image

We could for example offer an agent that is able to provide a Node-js package manager.

RUN apt-get install npm

docker run -tid --name go-cdagent-npm --hostname go-cdagent-npm \
   --net go-cd \ (1)
   -e AGENT_RESOURCES=NPM \ (2)
   softwarecraftsmen/go-cdagent-npm

1. Container is added to the network go-cd

2. Add a resource npm. This indicates that the agent is for example able to offer a Node.js package manager.
