<架构探险之路> Docker搭建微服务自动部署平台，让我们先来了解下Docker运行中的状态监控和内存控制吧！

Docker 之运行状态监控

调整Docker容器内存

查看当前内存占用情况

docker stats

CONTAINER ID        NAME                   CPU %               MEM USAGE / LIMIT     MEM %               NET I/O             BLOCK I/O           PIDS

可以通过添加-m来控制启东时的容器内存限制：

批量停止容器
```
docker stop `docker ps  -q`
```

批量删除容器

docker rm -f `docker container ls -a -q`

启动容器

registry

docker run -d -m 1024m -p 5000:5000 -v ~/docker-registry:/tmp/registry –name local-docker-res
–restart=always registry

nginx

xiazhaoyangdeMacBook-Pro:~ xiazhaoyang$ docker run -i -m 1024m -t -p 8000:80 --name nginx --restart=always env-nginx
[root@cfa1a6786510 /]# ps -ef|grep nginx
root        16     1  0 10:01 pts/0    00:00:00 grep --color=auto nginx
[root@cfa1a6786510 /]# cd /usr/local/nginx/sbin/
[root@cfa1a6786510 sbin]# ./nginx

[root@cfa1a6786510 sbin]# vi ../conf/nginx.conf
[root@cfa1a6786510 sbin]# ./nginx
[root@cfa1a6786510 sbin]#

docker-registry-web

docker run -it -m 1024m -p 8001:8080 --restart=always  --name local-docker-res-web  --link local-docker-res  -e  REGISTRY_URL=http://local-docker-res:5000/v2 -e  REGISTRY_NAME=localhost:5000 hyper/docker-registry-web

jenkins

docker run -d -m 1024m  -p 8002:8080 -v ~/jenkins:/var/jenkins_home --link github:github.com --name jenkins --restart=always jenkins
