Single-Node Installation
Since p2 is built with Kubernetes integration, the only supported method to run p2 is within such a cluster. To run p2 on a single node, it is recommended to use k3s. This page is a short guide on how to prepare your single node for p2.
Requirements
Hardware
| Without tier0 | With tier0 | |
|---|---|---|
| CPU | 2 Cores | 2 Cores |
| RAM | 2 GB | 4 GB |
| Disk | At least 20 GB recommended + your data |
Installing k3s
Installing k3s is very easy. Simply run the following script on your node to install the Cluster.
curl -sfL https://get.k3s.io | sh -
After the script is done, you should be able to run kubectl get node and see one ready node:
NAME STATUS ROLES AGE VERSION
p2-test-vm Ready master 13s v1.14.5-k3s.1
Congratulations, you now have a single-node Kubernetes cluster. By default, k3s installs traefik as Ingress Controller (= Reverse Proxy). There is however no default Persistent Volume Provisioner, which means we need the following component:
Installing local-path-provisioner
This tool allows Kubernetes to dynamically allocate "Volumes", pointing to a local path. Download the install-manifest as following:
wget https://raw.githubusercontent.com/rancher/local-path-provisioner/master/deploy/local-path-storage.yaml
The default base-path is /opt/local-path-provisioner. If you wish to change that path, edit the manifest to your needs.
Once you're done, apply the manifest with this command: kubectl apply -f local-path-storage.yaml.
To check that the provisioner has successfully been installed and is running, execture kubectl -n local-path-storage get pod. The output should look something like this:
NAME READY STATUS RESTARTS AGE
local-path-provisioner-848fdcff-h4l68 1/1 Running 0 10s
By default, the local-path-provisioner is not set as default. To change that, run
kubectl patch storageclass local-path -p '{"metadata": {"annotations":{"storageclass.kubernetes.io/is-default-class":"true"}}}'
Now that you have a fully-prepared Kubernetes cluster, you can continue with the normal Installation instructions here
