[slack-digest] [2019-03-22] #general
2019-03-22 08:13:12 UTC - Barry: Hi, How does Invoker determine how many containers it can launch?
I found that the number of containers is always maintained at a fixed value, exceeded will be removed.
Is it related to these configurations? And how to configure it ?
CONFIG_whisk_loadbalancer_invokerUserMemory=1024m
CONFIG_whisk_containerPool_userMemory=1024m

2019-03-22 08:42:16 UTC - Barry: What is the relation between invoker_user_memory size and container number ? e.g. invoker_user_memory = 1024m

2019-03-22 13:01:55 UTC - Carlos Santana: Hmm don’t get it. Whole purpose of the Jenkins PG test is to have a deployment of multiple VMs, make sure we can deploy. And also add the tests that we can shutdown one iniver and make sure that actions can continue to run with the other invokers that are still available

2019-03-22 14:56:11 UTC - Vincent Hou: VM1 launches all the services except invoker, VM2 launches invoker0 and VM3 launches invoker1. At the same time, we can do VM2 launches all the services except invoker, VM3 launches invoker0 and VM1 launches invoker1. Furthermore, VM3 launch all the services except invoker, VM1 launches invoker0 and VM2 launches invoker1. This topology can run 3 instances at the same time without interference.

2019-03-22 15:04:04 UTC - Vincent Hou: I am thinking of the following topology to orchestrate multiple distributed deployment of openwhisk with 3 VMs: VM1 launches all the services except invoker, VM2 launches invoker0 and VM3 launches invoker1. At the same time, we can do VM2 launches all the services except invoker, VM3 launches invoker0 and VM1 launches invoker1. Furthermore, VM3 launch all the services except invoker, VM1 launches invoker0 and VM2 launches invoker1. This topology can run 3 instances at the same time without interference. @Carlos Santana @Rodric Rabbah Does it make sense to you?

2019-03-22 20:23:38 UTC - Bin Wang: Hi. I’m running self-hosted Openwhisk on Kubernetes. The documentation says the Triggers limit is 60 per user per minute: <https://github.com/apache/incubator-openwhisk/blob/master/docs/reference.md#triggers>
This seems too low for production use.
