Docker，Entrypoint.sh 访问被拒绝

Question

I am trying to run a docker container by entering "docker compose up -d", but it keeps giving me the message:

Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/app/entrypoint.sh": permission denied: unknown

I have tried running it as sudo and given my entire project x rights, by running chmod a+x. I not sure how to fix this problem.

entrypoint.sh:

#!/bin/bash
set -ex
exec supervisord -c /app/supervisord.conf

supervisord.conf:

[supervisord]
nodaemon=true

[include]
files = /app/conf.d/*.conf

Dockerfile:

FROM debian:latest

Answer 1

Eventually solved the problem by simply running "docker compose build" before running "docker compose up -d".
