Deploying Applications in Azure

Requirments

Download Azure Cli

Open cmd/powershell/terminal and Login to Azure with

az login

AZURE CONTAINER REGISTRY. THE first step for all methods below.

Logging in

  1. Use the Azure GUI to create a new Azure Container Registry (CR).
  2. After having been logged in to azure log in to the CR run:
az acr login --name <acrname>

This should update the docker.config file itself so you can use docker command on the registry without logging in to docker for the next 3 hours.

  1. If for whatever reason it doesnt work or you want to remain logged in for long without relogging in to acr, you can login like this:
docker login <acrname>.azurecr.io

When prompted for username and password use one of this two ways to authenticate

First way

Go to the created resource

Settings > Access Keys > Check Admin user box ✓

User username and password provided there

Second way

az acr login --name <acrname> --expose-token

Use username: 00000000-0000-0000-0000-000000000000

Password: <accessToken returned created from --expose-token>

Naming the Images

The images must be properly tagged in order to be recognized by the push commands.

  • For single image do
docker tag <your_image> <acrname>.azurecr.io/<your_image>
  • For a docker compose file change the image property of each container to
- image <acrname>.azurecr.io/<your_image>

FOLLOW THE NAMING CONVENTION, lowercase alphanumerics and hyphen(-) ... DO NOT USE "_" in the container name or it might not run later. IMAGE name is not relevant, only the service name

Push Single Docker Image

docker push <acrname>-azurecr.io/<your_image>

Push by Docker Compose

Go to the correct directory where the docker-compose.yaml file is and

docker-compose push

The Super Easy way but limited in size of docker compose file

Through the Azure CLI create a Web App under App-Services. Choose Docker-Container for "Veröfentlichen" and under the Docker Tab select Docker Compose, Azure Container Registry and upload the docker-compose.yaml file. If you want to use the cli see here. Keep in mind that there is a limit on the size of the docker-compose file of 4000 characters when converted to Base64. (Aprox 1000 normal characters)

Container instances.

Through Docker compose built in deployment

Create a new docker aci context Switch to the context Do the "docker-compose up" command Limitations: Port mapping is not supported, meaning the ports must be identical Services on the docker compose file must follow the convention above.

Through az craete with yaml file that replaces the docker compose yaml
