如何将Env/Build Arg从Docker-Compose脚本传递到Dockerfile入口处命令？

我想将env/build var传递给我的dockerfile，以便在其入口处使用，并认为我可以从docker-compose文件中这样做，因此

  web:
    restart: "no"
    build:
      context: ../my-project
      args:
        CURRENT_ENV: "development"

在我的dockerfile中，我已经定义了这个定义

ARG CURRENT_ENV
ENTRYPOINT /bin/sh -c "rm -f /app/tmp/pids/*.pid && [[ $CURRENT_ENV = 'dev' ]] && /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile || /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile.hot; tail -f /dev/null"

，但是当我使用“ docker-compose”启动容器时在“ ='dev'”部分之前，入口点似乎没有拾取变量……

myco-deploy-web-1    | /bin/sh: -c: line 0: `rm -f /app/tmp/pids/*.pid && [[  = 'dev' ]] && /usr/local/rbenv/versions/2.4.5/gemsets/my-project/bin/foreman start -f Procfile || /usr/local/rbenv/versions/2.4.5/gemsets/my-project/bin/foreman start -f Procfile.hot; tail -f /dev/null'

什么是将构建arg/env var传递给我的入口处命令的正确方法？

I want to pass an env/build var to my Dockerfile for use in its entryxoint and thought I could do it from the docker-compose file like so

  web:
    restart: "no"
    build:
      context: ../my-project
      args:
        CURRENT_ENV: "development"

In my Dockerfile, I have this defined

ARG CURRENT_ENV
ENTRYPOINT /bin/sh -c "rm -f /app/tmp/pids/*.pid && [[ $CURRENT_ENV = 'dev' ]] && /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile || /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile.hot; tail -f /dev/null"

However when I start my containers using “docker-compose up”, it doesn’t appear the entry point is picking up the variable as it has a empty string before the “= ‘dev’” section …

myco-deploy-web-1    | /bin/sh: -c: line 0: `rm -f /app/tmp/pids/*.pid && [[  = 'dev' ]] && /usr/local/rbenv/versions/2.4.5/gemsets/my-project/bin/foreman start -f Procfile || /usr/local/rbenv/versions/2.4.5/gemsets/my-project/bin/foreman start -f Procfile.hot; tail -f /dev/null'

What’s the proper way to pass the build arg/env var to my ENTRYPOINT command?

入口点需要变量为环境变量，而不是构建arg。

你可以做到这一点

ARG CURRENT_ENV
ENV CURRENT_ENV $CURRENT_ENV
ENTRYPOINT /bin/sh -c "rm -f /app/tmp/pids/*.pid && [[ $CURRENT_ENV = 'dev' ]] && /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile || /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile.hot; tail -f /dev/null"

，它应该起作用

The ENTRYPOINT needs the variable to be an environment variable rather than a build arg.

You can do this

ARG CURRENT_ENV
ENV CURRENT_ENV $CURRENT_ENV
ENTRYPOINT /bin/sh -c "rm -f /app/tmp/pids/*.pid && [[ $CURRENT_ENV = 'dev' ]] && /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile || /usr/local/rbenv/versions/`cat .ruby-version`/gemsets/my-project/bin/foreman start -f Procfile.hot; tail -f /dev/null"

and it should work
