Kubernets cluster in Azure cloud
Links
Kubernets config
Use Declarative, we declare the state and kubectl implements using
kubectl apply -R -f configs/
Setup Cluster, using the Azure az commands and azure aks install-cli kubectl
- Use az tool, with docker run -it microsoft/azure-cli
in the container add the kubectl
az aks install-cli
list subscriptions
az account list --output table
set subscription to the one that contains k8s
az account set --subscription xx-xx-xx
run az proxy to connect the browser to kubernets admin in cloud
Proxy running on http://127.0.0.1:8001/ Press CTRL+C to close the tunnel... Forwarding from 127.0.0.1:8001 -> 9090 ## Problem only binds to loopback, in a container, if not using container for microsoft/azure-cli skip next command. nc -v -lk -p 8001 -s $(hostname -i) -e /usr/bin/nc 127.0.0.1 8001
List nodes
kubectl get nodes
If this fails with "Unable to connect to the server: dial tcp: lookup ...." reset with
rm .kube/config az aks get-credentials --resource-group <nameRG> --name >nameClusterInRG> kubectl get nodes
List namespaces
kubectl get namespaces
Test
- az - setup proxy tunnel to web admin
az aks get-credentials --resource-group K8S-xxx --name K8S-xxx
Merged "K8S-INF" as current context in /root/.kube/config
- kubectl get nodes
Create azure-vote.yml from https://docs.microsoft.com/en-us/azure/aks/kubernetes-walkthrough
kubectl apply -f azure-vote.yaml
