-----------------------------------------
Summary: Integrate with Docker.
Key: ZOOKEEPER-1940
URL: https://issues.apache.org/jira/browse/ZOOKEEPER-1940
Project: ZooKeeper
Issue Type: Wish
Reporter: David Medinets
Priority: Trivial
Docker is an open platform for developers and sysadmins to build, ship, and run
distributed applications.
It's become quite popular and I'd like to see the zookeeper community suggest a
standard way to run zookeeper inside docker containers. To get the conversation
started, I have a working example at:
https://github.com/medined/docker-zookeeper
I hope there is a better technique that I used. And if there is please make
suggestions.
The difficulty, I think, posed by Docker, is that the images are started before
the bridge network is created. This means, again I think, that zookeeper is
running inside the container with no way to communicate with the ensemble for
some non-trivial amount of time.
My resolution to this was to force each each to wait 30 seconds before
starting zookeeper. I still see connection errors in the logs, but eventually
the cluster settles and everything seems to work.
I'm hoping that someone which more networking experience than I can find a way
to eliminate that 30 second delay and the connection errors during startup.
Thanks for reading this far.
