Portainer manages multiple Docker container environments 1. Environmental preparation

# aliyun 2 core 8G139.196.95.123 install docker and Portainer# aliyun 1 core 2G 47.100.34.199 install docker# qingcloud 1 core 2G139.198.167.214 install docker2. Manage docker2.1 installation and run portaner

Install portaner on the server of aliyun 2core 8G

# install portainerdocker pull portainer/portainer# to start portainerdocker run-d-p 8080 var/run/docker.sock:/var/run/docker.sock 9000-- restart=always-v / var/run/docker.sock:/var/run/docker.sock-- modify the configuration file

Modify / usr/lib/systemd/system/docker.service on all three machines

# modify configuration file vim / usr/lib/systemd/system/docker.service# add configuration file content ExecStart= xxxx-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sockxxx represents the original parameters Append-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sock content # Save the startup file and restart the service systemctl daemon-reloadsystemctl restart docker# to see if it works ss-unlpt | grep 2375

2.3 add Node

# named docker-prod01docker-prod02# IP address 47.100.34.199Vue 2375139.198.167.214Rd 23752.4

The effect of the added docker node is as follows.

3. Trample record 3.1connection refused

FailureGet http://47.100.34.199:2375/_ping: dial tcp 47.100.34.199:2375: connect: connection refused

Profile information needs to be modified to add-H tcp://0.0.0.0:2375-H unix:///var/run/docker.sock content
