怎么利用docker-compose,在容器启动后执行自定义的shell命令,能不能在docker-compose.yml中配置啊? 5C

我想利用docker-compose同时启动多个容器,然后在每个容器启动后去执行一个自定义的
shell脚本,容器全部启动后执行也可以,主要是想在shell命令中能读取 .env中的配置项。
不知道在docker-compose.yml中能不能实现。
不明白 docker-compose中的command怎么使用

在docker-compose up后,无法执行容器中的命令,找不到容器内组件的环境变量

docker-compose.yml文件内容如下 cassandra: image: cassandra:3.7 ports: - "7000:7000" - "7001:7001" - "7199:7199" - "9042:9042" - "9160:9160" zookeeper: image: wurstmeister/zookeeper ports: - "2181:2181" kafka: image: wurstmeister/kafka ports: - "9092:9092" links: - zookeeper:zk environment: KAFKA_ADVERTISED_HOST_NAME: 127.0.0.1 volumes: - /var/run/docker.sock:/var/run/docker.sock 在运行docker-compose up,三个容器启动后,老同事的电脑可以直接执行kafka,cassandra等组件的命令如kafka-topics.sh, 在我的电脑上却不行,效果就好比这三个组件的环境变量没有export到本身系统中,请问如何解决? 谢谢!

docker-compose挂载镜像目录到宿主机用了volumes属性启动后镜像目录被删除了。

项目用docker-compose编排镜像启动,需要把一些文件挂载到宿主机便于修改配置,用到了volumes属性 ``` volumes: - "./docker/dev/WEB-INF:/usr/local/tomcat/webapps/cas/WEB-INF" ``` 前边是宿主机目录,后边是容器内得目录,启动后宿主机目录可以创建,但是容器内这个路径下什么东西都没有了,被删除了一样,不用volumes得时候可以正常启动并访问。
