We’ll start by defining a few environment variables. The reason behind declaring those variables is that we want to have a single place where critical information is stored. That way, when something changes (example:entry point to the cluster) we can modify a variable or two, and the changes will be propagated throughout all jobs.
Off we go. First, we need to open Jenkins global configuration screen:
open "http://$(docker-machine ip swarm-1):8082/jenkins/configure"
Note
A note to Windows users: Git Bash might not be able to use the open command. If that's the case, execute docker-machine ip <SERVER_NAME> to find out the IP of the machine and open the URL directly in your browser of choice. For example, the command above should be replaced with the command that follows:docker-machine ip swarm-1 If the output would be 1.2.3.4, you should open http://1.2.3.4:8082/jenkins/configure in your browser.
Once inside the configuration screen, please click the Environment...
