docker-kubernetes-course's Issues

egress traffic :- pod creation will not happen from local laptop, in UDR

Issue
kubectl run nginx --image=nginx
Unable to connect to the server: dial tcp 52.143.3.56:443: connectex: A connection attempt failed because the connected party did not properly respond after a period of time, or established connection failed because connected host has failed to respond.

We may need to add our local laptop public ip to firewall please do check

sample app Containerport - 80 or 8080

Just checking if on ingress-appgw.yaml , the containerport and targetport should be 8080 as desribed on the below official microsoft documentation

ExternalDNS is not working with

So I followed the tutorial on External DNS!

but I'm missing one thing, basically I have domain managed by Digital Ocean, and I copied the NS from azure and redirected the domain from digital Ocean to azure NS, then I checked using nslookup and it showed me that all the namespaces were directed to my ingress external-ip, I checked the DNS Zone on Azure portal, I got that all records were created, A and TXT alike!

but when I open subdomian.my-domin.de I get nothing!

I don't know if I'm missing something or the tutorial is missing something!

Exercise 23: Pod does not work. Please help

I have followed the tutorial twice but everytime it is same error. I think there is definitely something is wrong in creation of pod YAML file.
