djapp "connection refused" error

[alexei-led]

@karanvasnani hi
sorry it was my error: I've created app-mesh injector and controller manually, follwoing instructions on their github pages. I also did a typo mistake in mesh name (used _ instead of -). So the example did not work as expected.

Closing this issue.

p.s.: is there a way to see/debug such mistake? I was looking at logs, but could no see anything. IMHO troubleshooting documentation could be very helpful here.

Hey @alexei-led we're starting to look into this. We'll reply back soon when we know what's up or can suggest something.

@alexei-led can you provide output of kubectl get all -nprod. I tried but unable to reproduce.

root@dj-85dc6bb78-8jtrt:/usr/src/app# curl http://metal.prod.svc.cluster.local:9080/;echo
["Megadeth (Los Angeles, California)","Judas Priest (West Bromwich, England)"]
root@dj-85dc6bb78-8jtrt:/usr/src/app# curl http://jazz.prod.svc.cluster.local:9080/;echo
["Astrud Gilberto","Miles Davis"]

Same issue here. Curling Virtual Service Jazz and Metal do not redirect to weight distributed v1 and v2. Curling each version works. I went over Injector and CRDs twice with no success.

Please advise
