Docker compose run在入口点抛出错误

Question

运行以下cmd命令：

docker-compose up -d

抛出以下错误：

ERROR: for ubuntu_caddy_1  Cannot start service caddy: oci runtime error: container_linux.go:247: starting container process caused "exec: \"./caddy\": stat ./caddy: no such file or directory"

这是docker-compose.yml文件

services:
  caddy:
    image: abiosoft/caddy
    ports:
      - "80:80"
      - "443:443"
      - "2015:2015"
    volumes:
      - "./caddy-data:/root/.caddy"
      - "./config:/etc/caddy"
      - "./config/Caddyfile:/etc/Caddyfile"
    entrypoint:
      - ./caddy
      - "-conf"
      - /etc/Caddyfile
      - "-agree"
      - "-log=stdout"
      - "-port=443"
    restart: "on-failure: 10"
    user: root
version: "2"

你知道我会错过什么吗？

Answer 1

在abiosoft/caddy Dockerfile文件中，标准入口点是ENTRYPOINT ["/bin/parent", "caddy"] (link here)。

所以我认为你必须通过/bin/parent caddy来改变入口点中的./caddy。

我还认为您不必覆盖默认入口点，只需通过覆盖默认命令(即CMD ["--conf", "/etc/Caddyfile", "--log", "stdout", "--agree=$ACME_AGREE"])来指定要caddy的参数即可。

所以你最终选择了command: -conf /etc/Caddyfile -agree -log=stdout -port=443。
