• Explanations
  • Line 1: We start from an Alpine image that includes JDK 8. Newer Java version can be used, see Which Java versions is JobScheduler available for?
  • Line 5: Consider that $UID provides the numeric ID of the account that the JOC Cockpit installation inside the Docker container is performed for. This numeric ID typically starts above 1000 and should correspond to the account that is used on the Docker host, i.e. the account on the Docker Host and the account inside the container should use the same numeric ID. This mechanism simplifies exposure of the Docker container's file system.
  • Line 8-9: Adjust the JobScheduler release number as required.
  • Line 12-16: The installer tarball is copied and extracted to the container.
  • Line 22-23: The installer response file is copied to the container, for details of this file see next chapter. Then the installer is executed for the current user.
  • Line 26-28: An account and group "jobscheduler" is created that is handed over ownership of installed files.
  • Line 31-32: The start script is copied to the container, see below chapter Start Script.
  • Line 38: Port 4446 is exposed for later mapping. This port is used for the connection between user browsers and JOC Cockpit.
  • Line 41: The account "jobscheduler" that is the owner of the installation is exposed for later mapping. This account should be mapped at run-time to the account in the Docker Host that would mount an optionally exposed volume.
  • Line 43: The start script is executed to launch the JOC Cockpit daemon.

• Explanations
  • The above installer response file works for releases 1.13. Other releases ship with different versions of this file. You should pick-up a template of this file that matches your JobScheduler release by extracting the installer tarball. 
  • Generally all defaults of the response file can be maintained.
    • This includes use of port 4446 for the connection of user browsers to JOC Cockpit. At run-time this port can be mapped, see Dockerfile.
  • Line 182-233: The database connection makes use of a hostname "mysql-5-7" that is assumed to be the hostname of a Docker container in the same Docker network running the MySQL database.
    • Modify the database connection settings as required for use with your DBMS and access credentials.
