php - 将bin文件复制到docker容器会导致错误

Question

我正在尝试设置一个docker-compose系统，我想在启动时将开发工具复制到/usr/local/bin/。

那就是我的docker-compose.yml:

version: '3'

services:
  web:
    build: docker/container/nginx
    ports:
      - 4000:80
    volumes: &m2volume
      - ./src:/var/www/html/
      - ./docker/data/bin/:/usr/local/bin/
      - ~/.composer:/var/www/.composer
    networks: &m2network
      - www
    links:
      - "php"
      - "mariadb:mysql"
  mariadb:
    image: mariadb
    ports:
      - 8001:3306
    networks: *m2network
    ports:
      - "3307:3306"
    environment:
      MYSQL_ROOT_PASSWORD: magento2
      MYSQL_DATABASE: db
      MYSQL_USER: magento2
      MYSQL_PASSWORD: magento2
    volumes:
      - ./docker/container/db/docker-entrypoint-initdb.d/:/docker-entrypoint-initdb.d/
      - ./docker/container/db/conf.d:/etc/mysql/conf.d
      - ./docker/data/mariadb:/var/lib/mysql

  php:
    build: docker/container/fpm
    volumes: *m2volume
    networks: *m2network

networks:
  www:

如果我在其中保留 - ./docker/data/bin/:/usr/local/bin/，则会收到错误消息:

ERROR: for m2_php_1  Cannot start service php: oci runtime error: container_linux.go:262: starting container process caused "exec: \"docker-php-entrypoint\": executable file not found in $PATH"
Starting m2_mariadb_1 ... done

ERROR: for php  Cannot start service php: oci runtime error: container_linux.go:262: starting container process caused "exec: \"docker-php-entrypoint\": executable file not found in $PATH"

如果我取消注释，一切正常。

我在这里做错了什么？

Answer 1

如果我正确理解了这一点，并且映射了./docker/data/bin/:/usr/local/bin/卷会导致异常，则可能是因为mariadb镜像中定义了entrypoint。

更重要的是，您正在覆盖/usr/local/bin容器文件夹，该文件夹可能包含入口点中使用的可执行文件。当消失时，您会得到一个错误。
