docker - 用空格覆盖 docker 入口点

Question

我正在尝试使用 覆盖 docker 入口点 docker 运行 .这适用于 docker-compose:

  myapp:
    build: .
    security_opt:
      - seccomp:unconfined
    entrypoint: dlv debug local/myorg/myapp -l 0.0.0.0:2345 --headless=true --log=true --server
    volumes:

使用:

docker run --entrypoint "dlv debug local/myorg/myapp -l 0.0.0.0:2345 --headless=true --log=true --server"

结果是:

exec: \"dlv debug local/myorg/myapp -l 0.0.0.0:2345 --headless=true --log=true --se
rver\": stat dlv debug local/myorg/myapp -l 0.0.0.0:2345 --headless=true --log=true --server: no such file or directory

查看 How to properly override the ENTRYPOINT using docker run 的文章“Adrian Oprea” .

The documentation clearly states that the ENTRYPOINT only specifies the executable to run, when the container starts.

There is something a bit counter-intuitive here and if you take a good look at the example commands on the documentation page, you’ll see that the arguments are being passed after the image name.

在你的情况下:

 docker run --entrypoint dlv YOUR_IMAGE_NAME debug local/myorg/myapp -l 0.0.0.0:2345 --headless=true --log=true --server
                             ^^^^^^^^^^^^^^^
