调整Docker容器内存

查看当前内存占用情况

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

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
