Those Ops or sometimes Devs who'd like to get familiar with a full-fledged Rancher Kubernetes Engine and Rancher Server on their local machine using Multipass VMs to reduce their cloud costs. This implementation is not an alternative to k3d, k3s, k3sup, etc..
You need Multipass running on your local machine, to learn more about Multipass, please visit:
https://github.com/CanonicalLtd/multipass
This setup was tested on MacOS, but should work on Linux or Windows too.
You need to have about 6GB RAM and 24GB storage on your local machine.
You need kubectl in your path, if not, you can download the v1.15.0 version and put it in your path:
MacOS users:
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.15.0/bin/darwin/amd64/kubectlLinux users:
curl -LO https://storage.googleapis.com/kubernetes-release/release/v1.15.0/bin/linux/amd64/kubectlchmod +x ./kubectl
mv kubectl /usr/local/bin/Update 17/12/2019
Multipass v0.10.0 has been updated for MacOS Catalina, please download this release:
https://github.com/CanonicalLtd/multipass/releases
wget https://github.com/CanonicalLtd/multipass/releases/download/v0.10.0/multipass-0.10.0+mac-Darwin.pkg
sudo installer -target / -verbose -pkg multipass-0.10.0+mac-Darwin.pkg
snap install multipass --beta --classicPlease checkout the mojave branch:
git clone https://github.com/arashkaffamanesh/multipass-rke-rancher.git -b mojave-multipass-0.8Linux users should adapt the create-hosts.sh and adapt the network interface name. You can find the nic name with:
multipass launch --name test
multipass exec test -- bash -c 'echo `ls /sys/class/net | grep en`'Delete and purge the test VM:
multipass delete test
multipass purgeIf the above doesn't work somehow, shell into the node and get the nic name:
multipass shell test
ifconfigClone this repo and run the scripts as follow:
git clone https://github.com/arashkaffamanesh/multipass-rke-rancher.git
cd multipass-rke-rancher
./1-deploy-multipass-vms.sh
./2-deploy-rke.sh
./3-deploy-rancher-on-rke.sh
# or with mkcert to get a vaild certificate (on macos), you need to install mkcert, pls. have a look in the script
./ 3-deploy-rancher-on-rke-mkcert-macos.shor with a single command:
./deploy.shYou should get a running RKE Cluster on 3 Multipass VMs with Rancher Server on top in about 12 minutes (depends on your CPU / internet speed and docker hub performance).
You should get something like this at the End:
