Why do I need a shell script to run a python script inside the container?












0















Why does the first Dockerfile does not work? Meaning that it reports docker: Error response from daemon: OCI runtime create failed: container_linux.go:348: starting container process caused "exec: "python3 hello.py": executable file not found in $PATH": unknown.
ERRO[0001] error waiting for container: context canceled
, where as the second Dockerfile works like a charm?



In other words, why do I need a shell script to run a python script inside the container?



Dockerfile 1:



FROM python:3.7-alpine
COPY hello.py .
ENTRYPOINT [ "python hello.py" ]


Dockerfile 2:



FROM python:3.7-alpine
COPY hello.py .
COPY entrypoint.sh /usr/local/bin/
RUN chmod +x /usr/local/bin/entrypoint.sh
ENTRYPOINT [ "entrypoint.sh" ]
