// Docker env used for testing
// Different image may have different version tag
// because some of them are more stable than anoter.
//
// Docker images are maintained by PMC, cached in dockerhub
// and remains relatively stable over the time.
// Flow for upgrading docker env(need commiter)
//
// - Send PR to upgrade build script in the repo
// - Build the new docker image
// - Tag the docker image with a new version and push to tvmai
// - Update the version in the Jenkinsfile, send a PR
// - Fix any issues wrt to the new image version in the PR
// - Merge the PR and now we are in new version
// - Tag the new version as the lates
// - Periodically cleanup the old versions on local workers
//
