k8s-workshop

This repo contains materials for one-day App Dev on Azure Kubernetes Service training.

Lab preparation

We will use shell.azure.com cloud shell (bash) for experiments. Before you will start please create FORK of our repo git@github.com:azurecz/k8s-workshop-developer.git

Clone repo

mkdir myexperiment
cd myexperiment

# clone repo first
git clone https://github.com/azurecz/k8s-workshop-developer.git

# and now lets step into folder with project files.
cd k8s-workshop-developer

Create Azure Container Registry

We will use Azure container registry for our images, lets deploy ACR and push images there ..

Please use especially for ACR_NAME your unique name - it is unique in whole Azure environment in 'rc' file which contains all variable definition for our experiment. If you will run . rc first time it can produce few errors because not all resources exist yet.

# variables
. rc

# create resource group
az group create --location ${LOCATION} --name ${RESOURCE_GROUP}

# create ACR
az acr create --name $ACR_NAME --resource-group $RESOURCE_GROUP --sku Standard --location ${LOCATION} --admin-enabled true

# Get ACR_URL for future use with docker-compose and build
export ACR_URL=$(az acr show --name $ACR_NAME --resource-group $RESOURCE_GROUP --query "loginServer" --output tsv)
echo $ACR_URL

# Get ACR key for our experiments
export ACR_KEY=$(az acr credential show --name $ACR_NAME --resource-group $RESOURCE_GROUP --query "passwords[0].value" --output tsv)
echo $ACR_KEY

Create Azure Kubernetes Service

# aks - create cluster
az aks create --resource-group ${RESOURCE_GROUP} --name ${AKS_CLUSTER_NAME} \
  --no-ssh-key --kubernetes-version 1.13.12 \
  --node-count 3 --node-vm-size Standard_DS1_v2 \
  --location ${LOCATION}
# kube config
az aks get-credentials --name ${AKS_CLUSTER_NAME} --resource-group ${RESOURCE_GROUP}
# patch kubernetes configuration to be able to access dashboard
kubectl create clusterrolebinding kubernetes-dashboard \
  -n kube-system --clusterrole=cluster-admin \
  --serviceaccount=kube-system:kubernetes-dashboard

Setup access for AKS to ACR

# Get the id of the service principal configured for AKS
CLIENT_ID=$(az aks show --resource-group $RESOURCE_GROUP --name $AKS_CLUSTER_NAME --query "servicePrincipalProfile.clientId" --output tsv)

# Get the ACR registry resource id
ACR_ID=$(az acr show --name $ACR_NAME --resource-group $RESOURCE_GROUP --query "id" --output tsv)

# Create role assignment
az role assignment create --assignee $CLIENT_ID --role AcrPull --scope $ACR_ID
