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

Dockerfile

FROM mcr.microsoft.com/dotnet/core/aspnet:3.1

RUN mkdir /app

WORKDIR /app

COPY ./webapp/bin/Release/netcoreapp3.1/publish ./

COPY ./config.sh ./

RUN bash config.sh

EXPOSE 80

ENTRYPOINT [ "dotnet", "webapp.dll" ]

Building dotnet Web application

ls -ls ./webapp

dotnet build ./webapp

dotnet run --project ./webapp

curl http://localhost:5000

# Publish local build

dotnet publish -c Release ./webapp

# build docker image

docker build -t webappimage:v1 .

# Run the container

docker run --name webapp --publish 8080:80 --detach webappimage:v1

curl http://localhost:8080

docker stop webapp

docker rm webapp

docker image ls webappimage:v1
