Customers can choose when to update the containers that they've deployed. Containers are marked with standard Docker tags such as latest to indicate the most recent version. We encourage customers to pull the latest versions of containers as they're released. For details on how to get notified when an image is updated, see Azure Container Registry webhooks.
Container license files are used as keys to decrypt certain files within each container image. If these encrypted files happen to be updated within a new container image, the license file you have may fail to start the container even if it worked with the previous version of the container image. To avoid this issue, we recommend that you download a new license file from the resource endpoint for your container provided in Azure portal after you pull new image versions from mcr.microsoft.com.
To download a new license file, you can add DownloadLicense=True to your docker run command along with a license mount, your API Key, and your billing endpoint. Refer to your container's documentation for detailed instructions.
