Portainer可视化管理Docker集群

Portainer可视化管理Docker集群

Portainer是Docker的图形化管理工具，提供状态显示面板、应用模板快速部署、容器镜像网络数据卷的基本操作（包括上传下载镜像，创建容器等操作）、事件日志显示、容器控制台操作、Swarm集群和服务等集中管理和操作、登录用户管理和控制等功能。功能十分全面，基本能满足中小型单位对容器管理的全部需求。

1：单机部署

docker volume create portainer_data 
docker run -d -p 9000:9000 -v /var/run/docker.sock:/var/run/docker.sock -v portainer_data:/data 
portainer/portainer

2：Swarm集群部署

#管理节点上执行部署
curl -L https://downloads.portainer.io/portainer-agent-stack.yml -o portainer-agent-stack.yml
docker stack deploy --compose-file=portainer-agent-stack.yml portainer

[root@manager ~]# curl -L https://downloads.portainer.io/portainer-agent-stack.yml -o portainer-agent-stack.yml
