Hi OpenWhisk-developers, currently we have the problem, that we can only deploy one controller. Reason for this is some state, that is not shared across the controllers, which would result in a system which is not stable anymore.
To be able, to deploy more than one controller, I already looked into this topic. I've created a little document, to keep you on track and present you my ideas: https://github.com/apache/incubator-openwhisk/wiki/Design-discussion-on-HA-of-controller (https://github.com/apache/incubator-openwhisk/wiki/Design-discussion-on-HA-of-controller) Maybe you also have some ideas/concerns, that I missed so far. Just leave them as comment. There is also already a PR, which will address the first items that are described in the document above. https://github.com/apache/incubator-openwhisk/pull/2205 (https://github.com/apache/incubator-openwhisk/pull/2205) Greetings Christian
