Deploy PORTAINER

Use the official Demo preview.

Address: http://demo.portainer.io/

I. stand-alone deployment of PORTAINER

Use the following Docker command to deploy Portainer:

[root@192 ~] # docker pull portainer/portainer

[root@192 ~] # docker volume create portainer_data

[root@192] # docker run-d-p 9000 var/run/docker.sock:/var/run/docker.sock-v portainer_data:/data portainer/portainer

Note: restart when shutting down the selinux virtual machine, otherwise an error will be reported.

Visit the web page http://IP:9000

II. Deploy in a Swarm cluster

Note:

Add an image accelerator, or you may report an error when downloading the image later.

[root@manager ~] # vim / etc/docker/daemon.json

{

"registry-mirrors": ["https://registry.docker-cn.com"]"

}

Create a cluster and download the basic image. Every node in the cluster must have a portainer/agent image

1. Create a Docker Swarm cluster

[root@manager] # docker swarm init-- advertise-addr 192.168.10.102

[root@localhost ~] # docker pull portainer/agent # # download proxy image

1. Create two networks

[root@localhost] # docker network create-- driver overlay portainer_agent_network

[root@localhost] # docker network create-- driver overlay my-network

○ 22 deploys the agent as a global service in the cluster # # nodes need to be re-portainer/agent

[root@manager] # docker service create-name portainer_agent-network portainer_agent_network-publish mode=host,target=9001,published=9001-e AGENT_CLUSTER_ADDR=tasks.portainer_agent-mode global-mount type=bind,src=/var/run/docker.sock,dst=/var/run/docker.sock portainer/agent

3.Portainer instance deployment

○ 3 in the cluster, create a single Portainer visualizer container, default port 9000

[root@localhost] # docker service create-- name portainer-- network portainer_agent_network-- publish 9000 network portainer_agent_network network portainer_agent_network-- replicas=1-- constraint 'node.role = = manager' portainer/portainer-H "tcp://tasks.portainer_agent:9001"-- tlsskipverify

Browsers access http://IP:9000

○ 4 create an administrative user

○ 5 add managed nodes

Configure Endpoints Dashboard

Deploy the niigx service in the cluster. And create three copies of the test

[root@localhost] # docker service create-- name ngixn-test02-- network my-network-- publish 8888network my-network 80-- replicas=3 nginx

Image nginx:latest could not be accessed on a registry to record

Its digest. Each node will access nginx:latest independently

Possibly leading to different nodes running different

Versions of the image.

Download the image

Create a httpd service based on the downloaded image

When the browser accesses http://IP:90, you can see that the httpd service has been successfully created through Portainer.

7. Create and add private repositories

[root@manager] # docker run-d-v / home/root/registry:/var/lib/registry-p 5000 restart=always-- privileged=true-- name registry registry:latest

A7bf1601c3ebc28e1bff059638f0c9a7f602e525f55b1741f497026a56c33b31

Edit the daemon.json file and change it to a private warehouse address, which should be set on all three hosts.

[root@manager ~] # vim / etc/docker/daemon.json

{

"insecure-registries": ["192.168.10.102 VR 5000"]

}

[root@manager ~] # scp / etc/docker/daemon.json 192.168.10.103:/etc/docker/

[root@manager ~] # scp / etc/docker/daemon.json 192.168.10.104:/etc/docker/

Note: when Docker is restarted on three nodes, the previously created Portainer and portainer_agent services will not function properly.

At this point, you need to delete this service on manager and re-execute ○ 2 Murray-○ 5.

[root@manager ~] # systemctl restart docker # # restart docker on three nodes

[root@manager ~] # docker service rm portainer

Portainer

[root@manager ~] # docker service rm portainer_agent

Portainer_agent

Configure private warehouse

Create a private warehouse

[root@manager ~] # docker pull httpd

Upload the image to a private repository

Mark the mirror image

[root@manager] # docker tag httpd:latest 192.168.10.102:5000/httpd-test:2019-08-25

Upload the image to a private repository

[root@manager] # docker push 192.168.10.102:5000/httpd-test:2019-08-25

The push refers to repository [192.168.10.102:5000/httpd-test] # # Private warehouse

Create a service test for httpd (ibid.)

[root@manager] # docker service create-- name httpd-test02-- network my-network-- publish 8888purl 80-- replicas=3 192.168.10.102:5000/httpd-test:2019-08-25

Verify: Service converged

You can see that the task created based on the private repository image has been successfully deployed

Note: when creating containers, change to the address of the private warehouse.
