Adam B commented on MESOS-7272:
-------------------------------

Any progress here [~gilbert], [~jieyu]? Looks like it's marked as a Blocker for 1.3.0/1.2.1/1.1.2, so we'd like to land it this week (I see it's in the current sprint).

> Docker fetcher check the contentType strictly, while docker registry with version < 2.3 returns manifests with contentType `application/json`, that leading failure like `E0321 13:27:27.572402 40370 slave.cpp:4650] Container 'xxx' for executor 'xxx' of framework xxx failed to start: Unsupported manifest MIME type: application/json; charset=utf-8`.
