getting permission denied in docker run

Question

I am trying using Docker using Dockerfile.

My Dockerfile as follows, where I am using debian linux system.

FROM debian:jessie  ENV DEBIAN_FRONTEND noninteractive  ARG AIRFLOW_VERSION=1.7.1.3 ENV AIRFLOW_HOME /usr/local/airflow  .. ..  COPY script/entrypoint.sh /entrypoint.sh COPY config/airflow.cfg ${AIRFLOW_HOME}/airflow.cfg .. ..     USER airflow WORKDIR ${AIRFLOW_HOME} ENTRYPOINT ["/entrypoint.sh"] 

So when I run docker build -t test ., it build without problem.

However, when I run docker run -p 8080:8080 test.

It throws following error:

container_linux.go:247: starting container process caused "exec: \"/entrypoint.sh\": permission denied" docker: Error response from daemon: oci runtime error: container_linux.go:247: starting container process caused "exec: \"/entrypoint.sh\": permission denied". 

What is I am doing wrong ?

Answer 1

You need to change the permission of the bash file by chmod +x entrypoint.sh before calling ENTRYPOINT. So change your code to the following:

USER airflow WORKDIR ${AIRFLOW_HOME} RUN chmod +x entrypoint.sh ENTRYPOINT ["/entrypoint.sh"] 

Rebuild the image and run the container, it should work.
