Azure Docker app

A simple docker app that deploys a local Docker image to remote Azure Container Registry.

Requirements: .NET Core 6, Azure CLI, Docker

Running locally

dotnet run

Building your image

dotnet publish -c Release
docker build . --tag aspcontainers

To run your docker image locally:

docker run -d -p 5000:80 aspcontainers

Publish to Azure

Steps to publish your built image to ACR and hosting on ACI.

Set the common environment variables (change values as you need):

# Create Azure Container Registry
export rg='rg-dotnetapp'
export acr='acrdotnetapp'
export aci='acidotnetapp'
export location='eastus'

Login to Azure, create the ACR and push the docker image:

# login to Azure from the CLI
az login

# create the resource group
az group create --name $rg --location $location --output Table

# create the container registry
az acr create --name $acr --resource-group $rg --sku Basic --output Table

# push to acr
az acr login --name $acr
docker tag aspcontainers "$acr.azurecr.io/aspcontainers"
docker push "$acr.azurecr.io/aspcontainers"

Get the and set it to a variable export acrpass='<.....>'

az acr update -n $acr --admin-enabled true
az acr credential show --name $acr --query "passwords[0].value"

Set the name for your container instance:

dns='yourappdns'

Finally, create your container instance:

az container create \
  --resource-group $rg \
  --name $aci \
  --image "$acr.azurecr.io/aspcontainers:latest" \
  --cpu 2 \
  --memory 2 \
  --registry-login-server "$acr.azurecr.io" \
  --registry-username $acr \
  --registry-password $acrpass \
  --dns-name-label $dns \
  --ports 80 \
  --location $location

Your application should be available at http://yourappdns.eastus.azurecontainer.io. To enable HTTPS for Container Instances in Production, additional steps are required.

Destroy the resources

Don't forget to clean your resources to avoid unwanted costs:

az group delete -n $rg
