Docker 常用命令与环境变量排查

命令&步骤

1. 关闭docker 服务

# systemctl stop docker 

2.查看环境变量

# docker exec -it [container-id] env

• 查看Docker Root Dir: /apps/docker

# docker info

• 找到容器短id，再docker inspect [短id], 获取容器的长id：container-id

# dokcer ps

或者

# vim var/lib/docker/containers/[container-id]/config.json

3.修改环境变量

修改/var/lib/docker/containers/[container-id]/config.v2.json里对应的环境变量

• 修改容器配置信息

# vim var/lib/docker/containers/[container-id]/config.v2.json  

4.然后重启docker服务

# systemctl daemon-reload
# systemctl restart docker
