Frequently asked questions
Can Flagger be part of my integration tests?
Yes, Flagger supports webhooks to do integration testing.
What if I only want to target beta testers?
That's a feature in Flagger, not in App Mesh. It's on the App Mesh roadmap.
When do I use A/B testing when Canary?
One advantage of using A/B testing is that each version remains separated and routes aren't mixed.
Using a Canary deployment can lead to behaviour like this one observed by a user:
[..] during a canary deployment of our nodejs app, the version that is being served <50% traffic reports mime type mismatch errors in the browser (js as "text/html") When the deployment Passes/ Fails (doesn't really matter) the version that stays alive works as expected. If anyone has any tips or direction I would greatly appreciate it. Even if its as simple as I'm looking in the wrong place. Thanks in advance!
The issue was that we were not maintaining session affinity while serving files for our frontend. Which resulted in any redirects or refreshes occasionally returning a mismatched app.*.js file (generated from vue)
