• Kubectl on master node
• Docker-compose on master node

Installation

Installation is so easy with Docker-compose. Before up to docker compose you must do a few configuration. All steps should be installed to master node which Rancher cluster.

• Run docker-compose up.

Configration file environments

• proxmoxuser: Proxmox username.
• proxmoxpass: Proxmox user password.
• proxmoxhost: Proxmox hostname.
• proxmoxnode: Proxmox node that have Rancher cluster.
• proxmoxstorage: Storage that we want clone the template on Proxmox.
• timeout: Process timeout. (May up to three times.)
• templateid: Template ID of Rancher worker node that will be cloned.
• vmsubnet: Proxmox network Subnet IP address.
• templateip: IP address that worker node template necessary for some setups. (Must be an unused IP.)
• masterip: IP address of the master node.
• nodecommand: Docker command that will take from rancher for add new node.

Sample configuration should be as follows;

proxmoxuser=root@pam
proxmoxpass=123456
proxmoxhost=192.167.1.2
proxmoxnode=pve
proxmoxstorage=vms
timeout=180
templateid=201
vmsubnet=192.168.1.1
templateip=192.168.1.100
masterip=192.168.1.101
nodecommand="sudo docker run -d --privileged --restart=unless-stopped \
--net=host -v /etc/kubernetes:/etc/kubernetes -v /var/run:/var/run rancher/rancher-agent:v2.3.5 \
--server https://192.168.1.101:8443 --token rs576rlwrhmlhnzxp4zwh59ttpg67dnkrgx2wrgvtvxfln8k9ndfmg \

After docker-compose up command, the Web UI will be avaible at <master-ip>:8080 The port is changeable from docker-compose.yaml file.
