Setup Helm
You can setup Helm via OS specific package managers or from the binary releases.
If you prefer to install from binary releases, please download the Helm version that works with your OS and unpack it. Find the helm binary in the unpacked directory, and move it to its desired destination.
mv linux-amd64/helm /usr/local/bin/helmIf you prefer to install from binary releases, please download the Helm version that works with your OS and unpack it. Find the helm binary in the unpacked directory, and move it to its desired destination.
mv linux-amd64/helm /usr/local/bin/helmSimply create a bin folder under the home folder, add that folder to the User variable Path via Environment Variables for your account in Windows Settings.
That way any executable copied to this bin folder will automatically be on the path.
You can validate your installation by running:
helm version|

Setup Kubernetes
The profile my_profile is created to run the tutorial:
Having minikube installed and in your PATH, then run:
MacOS
minikube start --memory=8192 --cpus=3 --kubernetes-version=v1.22.0 --vm-driver=virtualbox -p my_profileLinux
minikube start --memory=8192 --cpus=3 --kubernetes-version=v1.22.0 --vm-driver=kvm2 -p my_profileWindows:
minikube start --memory=8192 --cpus=3 --kubernetes-version=v1.22.0 --vm-driver=hyperv -p my_profileAnd the output must be something similar like:
😄 [my_profile] minikube v1.22.0 on Darwin 11.3
✅ Created a new profile : my_profile
✅ minikube profile was successfully set to my_profile
😄 [default] minikube v1.22.0 on Darwin 11.3
✨ Selecting 'virtualbox' driver from user configuration (alternates: [hyperkit])
🔥 Creating virtualbox VM (CPUs=2, Memory=8192MB, Disk=50000MB) ...

🚀 Launching Kubernetes ...
⌛ Waiting for cluster to come online ...
🏄 Done! kubectl is now configured to use "my_profile"Finally configure to use minikube internal docker as docker host:
eval $(minikube docker-env -p my_profile)To run OpenShift4, you need to have one provisioned using try.openshift.com or can use any existing OpenShift4 cluster. Once you have your cluster, you can download the latest OpenShift client(oc) from here and add to your path.
oc version
You can check the OpenShift version using:
oc versionThe output should show oc version >=4.7:
Client Version: 4.7.0-202102130115.p0-c66c03f
Kubernetes Version: v1.22.0Then login into the cluster and run:
oc new-project my_profile
