2019-03-28 04:51:46 UTC - Xue Shuai: Hi, everyone, do i have to redeploy the entire openwhisk with openwhisk.yml every time I change parameters, eg. invoker_user_memory, or just redeploy invoker with invoker.yml? Thank you.

2019-03-28 04:55:25 UTC - Xue Shuai: @chetanm Thanks for your relpy, You mean that I can change the parameters `invoker_user_memory`, just redeploy invoker?

2019-03-28 05:06:00 UTC - Xue Shuai: Got it, thank you. By the way, i used ansible to redeoloy invoker and passed the env variable with -e before , like `ansible-playbook -i environments/local invoker.yml -e skip_pull_runtimes=True -e invoker_user_memory="2048m" ` . Is there any documnet for the tool `wskdev`. I only found a [readme](<https://github.com/apache/incubator-openwhisk/blob/ccac7d5131a80bddeb1b6dc0c6580051c90bc264/tools/vagrant/README.md>) mentioned it, I dont down how to change the env variable this way.
