Kubernetes & Azure (AKS, Terraform, Kompose, Kubectl, Azure CLI)

• Azure CLI configuration
• Infrastructure as code for Azure
• Generating Kubernetes configuration files with Kompose (Services, Deployments, Pods & Persistent volumes)
• Terraform with Azure Provider
• Kubectl configuration

Setting up Azure CLI

• Install Azure CLI -> https://docs.microsoft.com/en-us/cli/azure/install-azure-cli?view=azure-cli-latest
• Execute sh $ az login and authenticate with your Azure account
• Execute sh $ az account show --query "{subscriptionId:id, tenantId:tenantId" . Then copy subscriptionId and tenantId
• Execute sh $ az account set --subscription="${SUBSCRIPTION_ID}" . Replace ${SUBSCRIPTION_ID} for your subscriptionId copied

Create infrastucture in Azure (AKS Service with node master)

Terraform version >= v0.11.7

• Install Terraform -> https://www.terraform.io/downloads.html
• Edit vars with Azure Account values in sh terraform.tfvars
• After that:

$ terraform init
$ terraform plan
$ terraform apply

Setting up Kubectl with Azure account

• For apply Kubernetes files:

First configurate azure-cli with Azure account and install kubernetes tools with az:

$ az aks install-cli 

Then log in in to the Azure Container Registry (if you're using it, but dockerhub or other):

$ az acr login

After that, connect to cluster with Kubectl:

$  az aks get-credentials --resource-group docker-android --name k8s-docker-android

Running with custom K8s files (Recommended)

• You can use this approach or Kompose (Next 2 steps)

$ kubectl create -f volumes.yaml
$ kubectl create -f services_deployments.yaml

Generate Kube files with Kompose

• Install Kompose -> https://github.com/kubernetes/kompose

Kompose version: >= 1.1.0

• For convert to Kompose:

$ cd kompose
$ kompose convert -f ../kompose.yml

Execute Kube files (Kompose)

• First create Persistent Volume Claims, then Services; finally Deployments files. For example:

$ cd kompose
$ kubectl create -f nexus-7.1.1-claim0-persistentvolumeclaim.yaml 
$ kubectl create -f nexus-7.1.1-claim1-persistentvolumeclaim.yaml 
$ kubectl create -f nexus-7.1.1-service.yaml 
$ kubectl create -f nexus-7.1.1-deployment.yaml
