The Actual Problem and Solution:
I had a
Dockerfile that used an entrypoint that looked like
The real problem was the
docker-entrypoint.sh script was missing a #shebang.
So changing this
echo "ENV Var Passed in: $DEMO_VAR"
#!/bin/sh echo "ENV Var Passed in: $DEMO_VAR"
solved my issue!
Also note it'll depend on the base image
FROM <some linux distro> that may change what you're required #shebang should be.
