az acr task run equivalent in bicep

Question

Hi Team,

I have an Azure DevOps Git repo contenting a docker file to build a docker image of a self-host agent.

I've deployed a container registry instance via Bicep. I want to build this docker image using Bicep. I've looked into some samples where creating a "build-task" into the container registry instance using Bicep is possible, but I don't know how to trigger it.

The equivalent command in CLI:

az acr task create --registry mycrinstance --name taskhelloworld --image helloworld:latest --context "https://username@dev.azure.com/username/projectname/_git/reponame#main:foldername" --file "Dockerfile" --git-access-token "PAT" --platform linux/amd64

az acr task run --registry mycrinstance --name taskhelloworld

How can I achieve this using Bicep? Any guess?

Hi,

Triggering a task for container registry via bicep is not possible. The trigger action is basically not a state but operation/action. It is the same like starting or stopping a VM. Bicep simply does not supports operations. If you want to trigger it you could overcome this by using deployment script. The deployment script is a resource that can be deployed by Bicep that basically allows you to do operations by executing Az CLI or Azure PS commands.
