Java in a Container
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
