This article is to share with you rancher installation kubernetes cluster detailed installation tutorial, I believe that most people do not know how to install, in order to let you learn, to give you a summary of the following content, needless to say, let's read on.

1. Installation

Yum install docker-y # install docker

Systemctl enable docker # Boot starts automatically

Docker run-d-- restart=unless-stopped-p 80:80-p 443 rancher/rancher:stable

# pull rancher creation

two。 Log in and create a cluster

Account password admin admin

Create a cluster and add master nodes

# create and enable name for the cluster

# master node needs to check Etcd,contorl, and then copy the following code to the host of master to run.

3 add node node

# clusters created in the first selection

# Select a host and edit the cluster

# move to the last copy code and run it on the node node. Of course, the docker of the node node should be installed and started.

# it is recommended to go to the nodo node first and execute docker pull rancher/rancher-agent:v2.3.3 to pull down the image in advance.

# after installation, you can find that rancher can detect the node node.

4. Create pod

# Select cluster first, select namespace, and select deployment service in workload

# setting the name image path, etc., to complete the deployment is much more convenient than writing the yaml file

5. Install kubectl

Curl-LO https://storage.googleapis.com/kubernetes-release/release/v1.16.3/bin/linux/amd64/kubectl

# download the kubectl script, pay attention to the corresponding version. If you want to download 1.17, change the 1.16.3 above.

Chmod + x kubectl # give permission to run

Mv kubectl / usr/local/bin/kubectl # move to the running directory

[root@cs25] # mkdir ~ / .kube

[root@cs25] # cd ~ / .kube/

[root@cs25 .kube] # vim config

# go to rancher and copy out the configuration file of kubectl and paste it into the file above

# Test and view the node node

The above can be used, but the command cannot be completed. Set the completion function below.
