docker - Docker compose run 在入口点抛出错误

Question

运行以下命令：

docker-compose up -d

引发以下错误：

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"

知道我会在这里错过什么吗？

Answer 1

在 abiosoft/caddy Dockerfile 中，标准入口点是ENTRYPOINT ["/bin/parent", "caddy"]（链接在这里）。

所以我认为你必须改变./caddy你的入口点/bin/parent caddy。

我还认为您不必覆盖默认入口点，您只需通过覆盖默认命令（即CMD ["--conf", "/etc/Caddyfile", "--log", "stdout", "--agree=$ACME_AGREE"]）将您的 args 指定给 caddy。

所以你最终得到command: -conf /etc/Caddyfile -agree -log=stdout -port=443.
