Fail Early

Check the environment configuration and fail early in the ENTRYPOINT script:

 #
 # check the environment and fail early, when the container executed for the first time
 #
/opt/dsmanager/bin/dsmanager check-configuration || { echo "dsmanager configuration error" 1>&2; exit 1; }

/opt/dsmanager/bin/dsmanager check-configuration must exit with a non-zero value if the configuration fails.

Use .dockerignore
