Open 2 terminals:

- Terminal 2
# kubectl get namespace k8sgpt
-operator-system -o json > tmp.json
# vi tmp.json
# curl -k -H "Content-Type: application/json" -X PUT --data-binary @tmp.json http://127.0.0.1:38717/api/v1/namespaces/k8spt-operator-system/finalize

Goal:

The Bat signal has been lit in the sky, its time to suit up, & don’t let the kryptonite divide us. Fix the broken Minikube cluster

Lessons Learned:

  • Start up the Bat Mobile (Minikube)
    • See screenshot for a whole slew of commands
  • Create Object in YAML files to Confirm Cluster is up
    • Kubectl apply -f
    • Kubectl get po/pv/pvc

Start up the Bat Mobile (Minikube):

See screenshot for a whole slew of commands:

  • Minikube start
  • sudo chown -R
    • Change directory owner

      • .minikube
  • Minikube config set
    • Update the version
  • Sudo apt install -y docker.io
    • Get docker
  • Kubectl apply -f
  • Kubectl get
    • po
    • pv

A sprinkle of MiniKube & a pinch of Helm

by EarpMoonWater, posted in Helm, kubernetes

Goal:

So you got a Minikube cluster right? Now lets use Helm to deploy a microservice stack!

Lessons Learned:

  • Start Minikube Cluster
  • Unpack Helm, Move-it, Install, & Init
    • tar -xvzf ~/helm.tar.gz
    • sudo mv
    • Sudo helm init
  • Install Namespace w/Helm
    • sudo kubectl
    • sudo helm install
    • sudo kubectl
  • Edit to use Nodeport & Configure Nginx to Proxy

Start Minikube Cluster:

Edit to use Nodeport & Configure Nginx to Proxy:

tar -xvzf ~/helm.tar.gz:

sudo mv:

Sudo helm init:

Install Namespace w/Helm:

Sudo kubectl:

Sudo helm install:

Sudo kubectl:
