Setting up init container for resources

Invoke the following command to create a init-dockerfile.

FROM registry.access.redhat.com/ubi8/ubi:latest
RUN mkdir -p /jdbc_drivers/
COPY --chown=$CONTAINER_USER <all file names with space between them> /jdbc_drivers/
RUN chmod -R 775 /jdbc_drivers/

Invoke the following command to create init container image:

$ docker build -f init-dockerfile -t <container image name> .

This image needs to be pushed inside OpenShift or local registry for accessing inside cluster using either docker or podman:

• Login to registry:

  $ docker login <registry URL> -u <registry user> -p <registry user password>
  $ podman login <registry URL> -u <registry user> -p <registry user password>
  

• Tag image with registry:

  $ docker tag <wrapper image name with tag created above> <registry url>/<image name>:<tag>
  $ podman tag <wrapper image name with tag created above> <registry url>/<image name>:<tag>
  

• Push image to registry:

  $ docker push <registry url>/<image name>:<tag>
  $ podman push <registry url>/<image name>:<tag>
  

• This image will now be utilized in the init container image section to pass files, including database drivers, inside the container.
