Commands to setup Spinnaker on CentOS using Helm on Minikube

Important Points

• Run these commands through root user as Minikube driver is none

Installing kubectl

• https://kubernetes.io/docs/tasks/tools/install-kubectl/

cd ~
sudo curl -LO https://storage.googleapis.com/kubernetes-release/release/`curl -s https://storage.googleapis.com/kubernetes-release/release/stable.txt`/bin/linux/amd64/kubectl
sudo chmod +x ./kubectl
sudo mv ./kubectl /usr/local/bin/kubectl
kubectl version --client

Installing minikube

• https://kubernetes.io/docs/tasks/tools/install-minikube/

sudo curl -Lo minikube https://storage.googleapis.com/minikube/releases/latest/minikube-linux-amd64
sudo chmod +x minikube
sudo mkdir -p /usr/local/bin/
sudo install minikube /usr/local/bin/

Start minikube with driver none and setup dashboard

minikube start --driver=none --kubernetes-version v1.17.6
minikube status
minikube dashboard &
kubectl proxy --address='0.0.0.0' --disable-filter=true &

Install helm

• https://helm.sh/docs/intro/install/

curl -fsSL -o get_helm.sh https://raw.githubusercontent.com/helm/helm/master/scripts/get-helm-3
chmod 700 get_helm.sh
./get_helm.sh
helm repo add stable https://kubernetes-charts.storage.googleapis.com/

Setting up Spinnaker

• https://github.com/helm/charts/tree/master/stable/spinnaker

helm install spin-chart stable/spinnaker

• However this might give issues such as Depolyment and Statefulset of minio and redis target app/v1beta2 when it should be app/v1.

• Solution 1:

  • refer to helm/charts#20207
  • pull chart and unpack. Change deployment and stateful set apps/v1beta2 to apps/v1
  • update spinnaker version in values.yml

    helm pull stable/spinnaker -d ./spin --untar true
    

  • Use grep to find locate beta in directory and change it everywhere

    helm install spin-works . --debug
    

  • Same Error might stil arise with spinnaker clouddriver, change spinnaker version in values.yml.

• Solution 2 (untested):

  • https://kubernetes.io/blog/2019/07/18/api-deprecations-in-1-16/

  --runtime-config=apps/v1beta1=true,apps/v1beta2=true,extensions/v1beta1/daemonsets=true,extensions/v1beta1/deployments=true,extensions/v1beta1/replicasets=true,extensions/v1beta1/networkpolicies=true,extensions/v1beta1/podsecuritypolicies=true
  

• Usually the setup takes a lot of time, therefore wait and monitor from dashboard.

• If ceratin images fail to get downloaded, do it manually and reapply deployment from dashboard.

• Change ServiceIP of deck to NodePort or use the kubectl proxy.

• minikube spin-deck --ip to get IP.
