Introduction
Microshift is a small form factor OpenShift/Kubernetes optimized for edge computing.
Microshift-Plus uses MicroShift at its core but on top it provides tools which are important to deliver instant/local/minuscule OpenShift Environments for Development.
This is a prototype and comes with a set of helper script to setup & purge Microshift-Plus environments runing on Podman for dev/test/homelab setup.
Features
Microshift-Plus provides the following features
- Initialize & Start Podman Machine (for MacOS)
- Set
rootfulmode needed for Microshift's Privileged container - Launch Microshift Container
- Check and wait for Microshift to become Ready
- Patch OpenShift Router to use
nip.iofor outbound routing - Setup OpenShift Web/Developer Console for Microshift
- Get the URL of OpenShift Web Console for easy access
- Setup OpenShift Operator Lifecycle Manager (OLM) (For Operator Catalog)
- Scale down OLM packageserver replica to 1 (optimiaztion, default is 2)
Usage
- Install Podman
- Get the code
git clone https://github.com/ksingh7/microshift-plus
cd microshift-plus
- Lanuch Microshift environment (MacOS) sample output
./macos_create_microshift.sh
- Deploy a Sample App on Microshift
podman exec microshift oc create -f https://raw.githubusercontent.com/ksingh7/microshift-plus/main/02_sample_app.yaml
podman exec microshift oc get route
- Purge Microshift environment (MacOS)
./macos_purge_microshift.sh
