Az-204 - Prep - How To - Creating a container and access its service in Azure environment with ACR

Hello Team, 

Below commands can be used to create a container with image from ACR and to access the container service.

az login \

--username <> \

--password <> \

az group list | select -p name

# Deploying a container from public registry

az container create \

--resource-group "1-028b2503-playground-sandbox" \

--name psdemo-hello-world-cli-010 \

--dns-name-label psdemo-hello-world-cli-010 \

--image mcr.microsoft.com/azuredocs/aci-helloworld \

--ports 80

# show the container info

az container show --resource-group "1-5e3dbe31-playground-sandbox" \

--name "psdemo-hello-world-cli-009"

# Retrieve the container URL to access it over internet

URL=$(az container show --resource-group '1-5e3dbe31-playground-sandbox' \

--name 'psdemo-hello-world-cli-009' --query ipAddress.fqdn | tr -d '"')

echo "https://$URL"

# Demo 1 - Deploy container from azure container registry

## STEP 0 SET ENVIRONMENT VARIABLES

ACR_NAME="grsr18"

ACR_REGISTRY_ID=$(az acr show --name $ACR_NAME --query id --output tsv)

ACR_LOGINSERVER=$(az acr show --name $ACR_NAME --query loginServer --output tsv)

echo "ACR ID: $ACR_REGISTRY_ID"

echo "ACR_LOGINSERVER $ACR_LOGINSERVER"

## STEP 1 create a service principal and get the password and ID,

## this will allow azure container instances to pull

SP_NAME=acr-service-principal

SP_PASSWD=$(az ad sp create-for-rbac \

--name http://$ACR_NAME-pull \

--scopes $ACR_REGISTRY_ID \

--role acrpull \

--query password \

--output tsv)

SP_APPID=$(az ad sp show --id http://$ACR_NAME-pull --query appId --output tsv)

echo "Servce Princial ID : $SP_APPID"

echo "Service Princial Password $SP_PASSWD"

## STEP 2

az container create \

--resource-group "1-5e3dbe31-playground-sandbox" \

--name "psdemo-webapp-cli" \

--dns-name-label psdemo-webapp-cli \

--ports 80 \

--image $ACR_LOGINSERVER/webappimage:v1 \

--registry-login-server $ACR_LOGINSERVER \

--registry-username $SP_APPID \

--registry-password $SP_PASSWD

# due to permission issues if you cant create service princial

# then you can use your acr login creds to pull image

az container create --resource-group "1-028b2503-playground-sandbox" \

--name "psdemo-webapp-cli" --dns-name-label "psdemo-webapp-cli" \

--ports 80 --image $ACR_LOGINSERVER/webappimage:v1 \

--registry-login-server $ACR_LOGINSERVER --registry-username "GRSR18" \

--registry-password "xx=xxxxx=xxxxx+xxxxx"

# get the container status

az container show --resource-group "1-028b2503-playground-sandbox" \

--name "psdemo-webapp-cli"

az container show --resource-group "1-028b2503-playground-sandbox" \

--name "psdemo-webapp-cli" --query instanceView.state

# get the FQDN to access

url=$(az container show --resource-group "1-028b2503-playground-sandbox" \

--name "psdemo-webapp-cli" --query ipAddress.fqdn | tr -d '"')

echo http://$url

curl http://$url

# Get contianer logs

az container logs --resource-group "1-028b2503-playground-sandbox" \

--name "psdemo-webapp-cli"

# Delete the running container

az container delete --resource-group "1-028b2503-playground-sandbox" \

--name "psdemo-webapp-cli" --yes

# Cleanup from our demos, all ACIs and ACR Deployed in the resource group

az group delete --name "1-028b2503-playground-sandbox" --yes

docker image rm grsr18.azureacr.ip/webappimage:v1

docker image rm webappimage:v1

Az-204 - Prep - How To - Creating Azure Container Registry And Upload/Push docker image into Azure Container Registry (ACR)

 

Hello Everyone, 

This post contains below list of topics

1. How to create ACR ( Azure Container Registry )
2. How to login into ACR
3. How to push Docker images into ACR
4. How to build docker images with ACR

Github link contains a sample dotnet webapp, which we can build using given instructions. I will share the Github link soon. But you can build your own container image and upload it ACR with same instructions as give below.

# Login

az login --username "xxxx" --password "xxxx"

# Get the resource group name

az group list

# if you want to set subscription

az account set --subscription "SUB NAme"

# create a rg

az group create \

--name psdemo-rg \

--location centralus

# or list existing with

az group list

# Set ACR name , globally unique

ACR_NAME="GRSR810"

az acr create \

--resource-group "1-028b2503-playground-sandbox" \

--name $ACR_NAME \

--sku Standard

# login into ACR

az acr login --name $ACR_NAME

# Get the login server which is used in the image tag

az acr show --name $ACR_NAME --query loginServer

az acr show --name $ACR_NAME --query loginServer --output tsv

ACR_LOGINSERVER=$(az acr show --name $ACR_NAME --query loginServer --output tsv)

echo $ACR_LOGINSERVER

Tag the container image using the login server name.

docker image ls webappimage:v1

docker tag webappimage:v1 $ACR_LOGINSERVER/webappimage:v1

docker image ls $ACR_LOGINSERVER/webappimage:v1

docker image ls

# Push the image into Docker registry

docker push $ACR_LOGINSERVER/webappimage:v1

# Get list of the repositories and images/tags from ACR

az acr repository list --name $ACR_NAME --output table

az acr repository show-tags --name $ACR_NAME --repository webappimage --output table

# By using tasks we can build ACR with tasks.

az acr build --image "webappimage:v1-acr-task" --registry $ACR_NAME .

# 2 images must be there now

az acr repository show-tags --name $ACR_NAME --repository webappimage --output table
