Test to bring down containers
Hi All,
We wanted to have some kind of a Chaos Monkey test wherein we could bring
down containers running operators in a controlled fashion. Could anyone
kindly suggest a way/script that could bring down the containers?
We are trying test the HA feature of our application running on Apex.
Thanks & Regards,
Devavrath S

Hi Devavrath,
You can restrict memory of your container by turning operator and buffer
server memory. More details can be found at:

Apex CLI provides "list-containers" and "kill-container" commands, you can
call them from the scripts. AppMaster exposes all these functionalities as
REST apis, so you can directly call them as well.
In the released version of the Apex, killing the AppMaster-container
restarts all the other containers, which is fixed in the SNAPSHOT version
and will be part of next release.
