Timothy Chen updated MESOS-3377:
--------------------------------
Fix Version/s: 0.25.0
> mesos docker container with container_name as ENV variable
> ----------------------------------------------------------
>
> Key: MESOS-3377
> URL: https://issues.apache.org/jira/browse/MESOS-3377
> Project: Mesos
> Issue Type: Wish
> Components: docker
> Affects Versions: 0.25.0
> Reporter: Wojciech Sielski
> Priority: Minor
> Fix For: 0.25.0
>
>
> 1. Long story short:
> We have mesos and marathon (and other app) based PaaS.
> https://github.com/eBayClassifiedsGroup/PanteraS
> We use mesos with consul and registrator as a glue app that register in
> consul docker containers.. Some tricky part we have with deregistering
> container BEFORE it is killed, but after SIGTERM is received.
> To do that we use bash wrapper script that trap SIGTERM
> https://github.com/eBayClassifiedsGroup/PanteraS/blob/master/frameworks/start.sh#L45
> and put container into consul maintenance mode.
> Till that part everything works perfectly fine - so when marathon re-deploy
> container it is smoothly taken out from consul (and loadbalancers)
> To take service out from consul, we need to know consul service id = which is
> based on mesos container name (this is how registrator do that).
> We did kind of easy docker wrapper that inject mesos name as ENV variable:
> https://github.com/eBayClassifiedsGroup/PanteraS/blob/master/infrastructure/docker
> BUT
> Since new mesos release, mesos doesn't use local docker binary, but docker
> socket and API. So our workaround will not work anymore.
> 2. What we need - our wish :) :
> Just injection of docker mesos name as ENV variable.
> Since this is the easiest way of getting it, so we can easy deregister it.
> ps.
> Yes, we know that you can do docker inspect to get that - but this require
> docker application - in smallest container we cannot have it.
> Yes, we know that you can get it from docker API (same like inspect)
> but much much easier is 12 factor app rule to follow and have it as ENV
> variable.
