josephevans opened a new pull request #19654: URL: https://github.com/apache/incubator-mxnet/pull/19654
## Description ## This PR is experimental - change the docker tag used in build containers to use a new single ECR registry (defined in a Jenkins environment variable) to retrieve and store build containers. This creates a unique docker tag based on the hash of the Dockerfile and platform, so once a container is built using a specific Dockerfile, we will cache it automatically for future CI runs. This should allow CI to be more stable and faster because we won't have to rebuild the containers on every CI run (master branch already reuses containers, but other branches do not currrently.) On the down-side, if some upstream packages are updated that would normally start causing builds to fail, we may not be alerted to it until the dockerfile is changed which would alter the tag. There is a possibility of having images automatically expire and forcing CI to rebuild them at a regular interval. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
