[shellclear]

… docker-push target of Makefile

SUMMARY

When using Podman as the container engine, the container build process fails with the error:

./up.sh: line 88: docker: command not found.

ISSUE TYPE

• Bug, Docs Fix or other nominal change

ADDITIONAL INFORMATION

I added the ENGINE variable as the value of the CONTAINER_CMD variable that is passed to the docker-build and docker-push targets of the Makefile and now the image is built and pushed when using podman as container engine.
