Proposal: Support the use of image digest
Summary
There are some in the wider container industry who would prefer to make use of image digest hashes as opposed to tags, as tags can be re-assigned or "drift".
Here's a fair article on the topic.
I propose we look into the templating requirements to support the use of @sha256:HASH formatted values for image.tag, in addition to the traditional :tag format.
Current behavior
See this Issue discussion, where we had an issue with the image build itself in the CNG, and had to re-build that image for the proper content. This new image then needed deployed.
Expected behavior
Have the ability to strictly define the image to be used.
