docker cp 和docker exec 查看docker 运行的容器信息

Posted 2020-12-03 jinanxiaolaohu

1. 使用docker 运行 redis 和 postgresql

docker run -d -p 6379:6379 -v /redis/data/:/data redis

docker run -d -p 5432:5432 -v /postgres/data:/var/lib/postgresql/data postgres

2. 验证工作目录

docker inspect redis 

3. 查看 contrainer的名字

docker ps

CONTAINER ID        IMAGE                 COMMAND                  CREATED             STATUS              PORTS                    NAMES
09370c8d3f66        redis                 "docker-entrypoint..."   2 hours ago         Up 2 hours          0.0.0.0:6379->6379/tcp   determined_turing
b729386f1712        postgres              "docker-entrypoint..."   2 hours ago         Up 2 hours          0.0.0.0:5432->5432/tcp   mystifying_beaver

4. 进入redis 进行操作

docker exec  -it determined_turing redis-cli

5. 将 images 里面的内容都copy到host的物理路径下面

docker cp determined_turing:/ /redis

交换顺序就能够将 宿主机的内容 复制到 docker container里面去了.
