az acr create -n <ACR_NAME> -g gab2018 --sku Basic --admin-enabled true

LOGIN_SERVER=$(az acr list -g gab2018 --query "[].{acrLoginServer:loginServer}" --output tsv) echo $LOGIN_SERVER

Pubish docker image to registry

  1. Login to registry

az acr create -n <ACR_NAME> -g gab2018 --sku Basic

LOGIN_SERVER=$(az acr list -g gab2018 --query "[].{acrLoginServer:loginServer}" --output tsv) echo $LOGIN_SERVER

ACR_SECRET=$(az acr credential show -n <ACR_NAME> --query "passwords[0].value")

echo $ACR_SECRET

echo "$ACR_SECRET"| docker login -u gab18lab --password-stdin $LOGIN_SERVER

  1. Tag and Push image

docker tag azure-vote-front $LOGIN_SERVER/azure-vote-front:v1 docker push $LOGIN_SERVER/azure-vote-front:v1

  1. List images in registry

az acr repository list --name gab18lab --output table

  1. Test pull command

CLIENT_ID=$(az aks show -g gab18aks --name gab18aks --query "servicePrincipalProfile.clientId" --output tsv)

echo $CLIENT_ID

ACR_ID=$(az acr show -n <ACR_NAME> -g gab2018 --query "id" --output tsv)

echo $ACR_ID

az role assignment create --assignee $CLIENT_ID --role Reader --scope $ACR_ID
