An application is built and pushed to an Azure Container Registry in one vsts project and is tagged with the application version & build id.
In a separate project I want to do a release whenever a new image is pushed into the repository. I can use the Azure Container Repository as artifact but how would I get the correct image tag?
ACR Provides Webhooks for Push and Delete. Within the Webhook payload, you can find tag information. https://docs.microsoft.com/en-us/azure/container-registry/container-registry-webhook-reference If you wire up a push webhook to your release definition, just parse out the tag information and you should be good to go.
