Alarm and log collection function

Multi-cluster management function

Integrated Rancher Kubernetes Engine (RKE)

Integration with cloud Kubernetes services (such as GKE, EKS, AKS)

2. Installation requirements 2.1 operating system and Docker requirements

2.2 hardware requirements HA cluster

Single node

Port requirements for 2.3Rancher to communicate with user clusters

3. Single node installation

Docker run-d-restart=unless-stopped\

-p 80:80-p 443purl 443\

-v / usr/local/rancher:/usr/local/rancher\

4. Rancher's web interface 4.1 access the web interface and log in through the host's IP

Set the URL address that needs to be accessed

Set Chinese font

Add Cluster

Generate your own cluster

You can customize the RKE cluster, or you can import the cluster you have already built.

4.2 customize a cluster first

Set the name of the custom cluster and select the version of the cluster that needs to be installed.

Select the required network policy

Set up according to your own needs

After selecting the master node, run the following command after you need to install it as a master node

Run the following command on the work node

The running process will pull the required images, depending on your network conditions.

After all the containers are running, you can see the following interface, indicating that your cluster is ready.

At this point, the custom cluster is complete.

4.3 Import the created cluster

Define a random cluster name

Copy the following two commands to run on the master node. When running the first command, because the self-signed certificate will report an x509 error, just skip the error when executing the following command

When you see it on the master node

See in the rancher interface

Then the import is successful!
