Fwd: Zookeeper on Docker
Hi. I'm working to containerize Zookeeper with Docker. I think I'm nearly
there. But still need to add myid files to each node in the ensemble. If
anyone is inclined, I'll appreciate any help or advice. My project is at
https://github.com/medined/docker-zookeeper. It starts a three-node
zookeeper ensemble and a web-based application to view the contents of the
ensemble.

To followup to my saga, the dockerized zookeeper is working with a three
node ensemble. I can see Leader Election in logs of one images. And also
Following messages in the other. The node do sleep for 30 seconds so the
bridge network can be established which might be incorrect but it's working
so good enough for now.

Sadly, I am seeing the following message in the image logs. I had thought
once the bridge was created on the host, then the images would see each
other.

I've updated my github project so that the zoo.cfg has the IP's from the
br0 bridge network. And have created the myid files inside the images when
they get started.

Yes before starting the server. When the server starts up, it looks for the file myid in the data directory.

That file needs to be in place before zookeeper spins up?

That file needs to be in place before zookeeper spins up?

Hi David,
You can place 'myid' file in server's data directory, as specified by the configuration file parameter dataDir.
For example: dataDir=/home/zookeeper-data/
Keep like /home/zookeeper-data/myid

Hi. I'm working to containerize Zookeeper with Docker. I think I'm nearly there. But still need to add myid files to each node in the ensemble. If anyone is inclined, I'll appreciate any help or advice. My project is at https://github.com/medined/docker-zookeeper. It starts a three-node zookeeper ensemble and a web-based application to view the contents of the ensemble.
