How can I perform a rolling restart of the Okera cluster?
When Okera performs a rolling restart of its services, it stops a given instance and then launches a replacement instance based on the same docker image. This will reset the connection count as the replacement workers will not have any of the connection information from the last worker instance.
./cerebro_cli clusters restart
To see the progress of the restart, you can run:
sudo docker ps
Note the values in the "CREATED" column. This is the time that the current instance of a given docker container has been running.
