OpenShift is a distribution of Kubernetes focused on continuous and multi-tenant application development. Come and learn how to deploy a Java application to Kubernetes, how to connect it to a database, how to scale it up and down and how deployments can be triggered by commits in a git repository

Agenda:

  • ¬†Introduction to OpenShift/Kubernetes
  • Start an OpenShift cluster using minishift
  • Deploy a Java application
  • Deploy a database and wire it with the application
  • Scale up/down
  • Deployments triggered by commits in a git repository

The workshop has a few pre-requisites:

  • Participants need to access the internet during the workshop to download a couple of hundreds of MB of Docker images
  • Ideally, participants come with the following software installed on their laptops:
    • Hypervisor:
      • KVM or VirtualBox on Linux
      • Hyper-V or VirtualBox on Windows
      • xhyve or VirtualBox on macOS)
    • `oc`, the OpenShift client tool: download openshift-origin-client-tools suitable for your platform and add the `oc` executable to `PATH`
    • Minishift – see Installing Minishift
