• 容器状态

# start

# restart
docker restart happy_hahaha
# stop
docker stop happy_hahaha
# pause
docker pause happy_hahaha
docker unpause happy_hahaha

• 运行容器

# docker run
docker run --name centos7.3 -i -t centos:7.3.1611 /bin/bash
# --detach => -d
docker run --name centos7.3_d -i -t -d centos:7.3.1611 /bin/bash
# 自动重启
docker run --restart=always
# 挂载数据卷
docker run --rm -it -v /host/data/:/data:rw happy_hahaha /bin/bash
docker run --name centos7.3-elk -dit -v /Volumes/HDD/dockerdata:/data:rw -p 8080:80 -p 5601:5601 -p 9200:9200 --privileged=true shawnyan/docker:centos7.3.1611 /usr/sbin/init
# rename
docker rename centos7.3 centos7.3.1611

• 容器交互

docker exec -t -i centos7.3 /bin/bash
docker exec -it centos7.3 /bin/bash

• 查看镜像

docker images
docker images shawnyan/docker
docker image ls -a
docker image rm <CONTAINER ID>
docker image rm `docker image ls -a -q`
# 构建镜像的每一层
docker history <id>

• 删除容器

docker rm <CONTAINER ID>
docker rm `docker ps -a -q`

• 监控容器

docker ps
docker ps -a
docker container ls -a
# status
docker stats centos7.3
docker logs centos7.3
docker logs -ft centos7.3

• 查看容器信息

# In Liquid format double '{}' means variables.
docker inspect centos7.3
# docker inspect centos7.3 --format='\{\{ .ID \}\}'
# docker inspect centos7.3 --format='\{\{ .NetworkSettings.IPAddress \}\}'
# docker inspect centos7.3 --format='\{\{ .State.Status \}\}'

• 导出导入镜像

# export
docker save -o ol7.tar oraclelinux:7-slim
# import
docker load -i ol7.tar

• 提交定制容器

docker commit -m "comment" <CONTAINER ID> <user/repo>
docker commit -m "centos7.3 core" -a "shawnyan" e819c4cb23a4 shawnyan/docker:centos7.3
docker commit -m "centos7_v2" -a "shawnyan" centos7 shawnyan/docker:centos7_v2

• 推送镜像

docker push <user/repo:tag>
