I just had my dockerized app not able to build for a day because apparently the "ubuntu:14.04" image still gets revved over time, and a newer OS level package version sabotaged me (this was unexpected - I'm careful to only apt-get install, pip install, etc. hardcoded versions of package so that I know when they change). Is there a way to control how/when I'm getting "newer 14.04's"? Not a desktop hack, I need it to work on the build server too when I submit my app to build.

See https://hub.docker.com/_/ubuntu/ you can find 14.04, or 14.04.4 (which the now the latest) – user2915097 May 27 '16 at 21:05

Ubuntu publish dated tags to the registry.
$ docker run ubuntu:trusty-20160526 cat /etc/lsb-release
DISTRIB_ID=Ubuntu
DISTRIB_RELEASE=14.04
DISTRIB_CODENAME=trusty
DISTRIB_DESCRIPTION="Ubuntu 14.04.4 LTS"

How reliable are these? I note with sadness that there's a lot more trusty-
than there are 14.04.x tags, which tells me they update the 14.04.x tags across several real builds? Are even the trusty- – Ernest Mueller May 31 '16 at 18:46ones guaranteed to be stable? -
I can't say for sure as I'm not involved in the process but it looks like they increment a build number `.1`, `.2` etc for multiple builds on the one day. – Matt Jun 02 '16 at 12:04
