Creation of the WebApp Service
In vscode, docker extension, rightclick the image -> Push -> Follow the instructions to correctly tag the image, and create a new webapp if required.
The image is uploaded and build in the container registry. The WebApp is setup to CI/CD from the container registry.
Debugging / Logging
When in the webapp service -> deployment center -> logs, we find logs of the webservice. Sequency of the output log looked like:

Does not make much sense. To find the actual problem, go to your-app-service -> Diagnose and solve problems -> Application logs.
Here, I found out the python error supplied by the container (originating in this case from azure.py).
Create an Azure Container Registry
Azure Container Registry provides storage for Docker images in the cloud.
Either create it in the Azure portal, or with the Azure CLI or Cloud Shell (icon in the toolbar of Azure portal) using:
1
| az acr create --name myregistry --resource-group mygroup --sku standard --admin-enabled true
|
You can ofcourse build you image locally yourself, or upload the Docker file and other files and let Container Registry build it:
1
| az acr build --file Dockerfile --registry myregistry --image myimage .
|
The ‘.’ at the end points to the repository, so make sure you are in the correct folder or use the path.
Problem solution: No Azure environment variables available in container
Use the following magic in entrypoint.sh, before the runserver call:
1
| eval $(printenv | sed -n "s/^\([^=]\+\)=\(.*\)$/export \1=\2/p" | sed 's/"/\\\"/g' | sed '/=/s//="/' | sed 's/$/"/' >> /etc/profile)
|
It copies all environments of the azure environment to the container environment.
Use local az CLI
After installation, access from cmd (or PowerShell but fuck PowerShell).
Type:
This will redirect to a web login.
Difference between Container Registry and Container Instances
The one registres, while the other actually instantiates? No clue.
Problems resolve
As with everything Microsoft, it rarely actually works. I cant access the ACR.

I have downloaded docker desktop for windows.
I will always create the containers locally or via Docker Hub because FUCK MICROSOFT.
