Follow the installation steps to configure your own Jenkins on Oracle Cloud Compute always FREE shape

  1. Create a compute instance using either
    VM.Standard.E2.1.Micro - if you do not intend to run CI/CD with 23c Free, since this shape does not provide sufficient resources to mount the DB.
    or
    If you are following my APEX CI/CD guide, your choice of...
    a. (Recommended) VM.Standard.E2.1 shape, provides more memory over the VM.Standard.E2.1.Micro and get run 23c Free, however, it is not an always-free instance.
    b. As Mohamad Subhi Bouchi suggests, a more expensive VM.Standard.E3.Flex with 15GB memory & 1 Gbps bandwidth.
