Docker images version change do not trigger terraform container update

Question

I'm using terraform to create container on Azure using azure_container_group. My container is based on a docker image stored on a private registry. When I update this image by pushing a new version with the latest tag my docker image have a new SHA256 ... but terraform seems not able to trigger this update. Am i missing something ?

Thanks,

Dan

First of all, Azure Container Instance does not have the feature that automatically updates the images. So you need to update the images yourself manually. And Terraform is just a tool to create the Azure Container Instance, you can use it to create a trigger to update the images, but you cannot use Terraform itself to do it.

To automatically update the images, I recommend you use the Azure Container Registry, it provides the trigger on the commit to update the images. Take a look at Automate container image builds in the cloud when you commit source code.
