porainer安装使用

机器环境

本实践将在 Ubuntu 22.04.3LTS 系统上进行安装测试
docker 版本，原则上docker版本无影响

安装portainer操作脚本

参考资料 Linux install

# DockerStandalone

# 默认方式
docker run -d -p 8000:8000 -p 9443:9443 --name portainer --restart=always\
 -v /var/run/docker.sock:/var/run/docker.sock \
 -v portainer_data:/data portainer/portainer-ce:2.14.2

# 安装到特定网络 , net_default已经提前创建完成
docker run -d -p 8000:8000 -p 9000:9000 --name portainer --restart=always\
 -v /var/run/docker.sock:/var/run/docker.sock --network net_default\
 -v portainer_data:/data portainer/portainer-ce:2.14.2

安装代理到已经存在的portainer

 # Add an environment to an existing installation
 ## Docker Standalone
 docker run -d -p 10.10.4.128:9001:9001 --name portainer_agent --restart=always\
  -v /var/run/docker.sock:/var/run/docker.sock \
  -v /var/lib/docker/volumes:/var/lib/docker/volumes portainer/agent:2.14.2
  
# Add k8s
curl -L https://downloads.portainer.io/ee2-14/portainer-agent-k8s-nodeport.yaml -o portainer-agent-k8s.yaml; 
kubectl apply -f portainer-agent-k8s.yaml

访问

访问地址： docker http://10.10.4.128:9000 k8s http://10.10.4.128:30778

配置到ingress

portainer_ingress.yaml

apiVersion: networking.k8s.io/v1
kind: Ingress
metadata:
  name: portainer
  namespace: portainer
  annotations:
    nginx.ingress.kubernetes.io/proxy-body-size: "0"
spec:
  rules:
  - host: portainer.example.com
    http:
      paths:
      - path: /
        pathType: Prefix
        backend:
          service:
            name: portainer
            port:
              number: 9000
  ingressClassName: nginx

ingress 访问地址

http://portainer.example.com

重置密码

某一天忘记密码或其他异常导致密码被动忘记掉

1. 找到portainer的数据目录 portainer_data:/data

   docker安装用 docker inspect container_name or container_id 查看
        "Mounts": [
           .....
           {
               "Type": "bind",
               "Source": "/data",
               "Destination": "/data",
               "Mode": "",
               "RW": true,
               "Propagation": "rprivate"
           }
       ],
   
   
   k8s安装用 kubectl describe pods  portainer-5d4754696-ngdn6 -n portainer 查看 
       Volumes:
       data:
           Type:          HostPath (bare host directory volume)
           Path:          /data
           HostPathType:  Directory

   上面找到的真实地址是 /data

2. 关闭portainer

3. 运行重置命令

docker run --rm -v /data:/data portainer/helper-reset-password

{"level":"info","filename":"portainer.db","time":"2024-03-28T01:10:00Z","message":"loading PortainerDB"}
2024/04/01 01:10:00 Password successfully updated for user: admin
2024/04/01 01:10:00 Use the following password to login: ~3%2gWf,hb[n5$4F:UI0w78x!QE{l6Zt

输出日志中包含有 admin的密码 ~3%2gWf,hb[n5$4F:UI0w78x!QE{l6Zt

4. 启动portainer

5. 输入上述密码 ，登录portainer后台，修改密码。
