Lab 7.2 Not the expected results... I'm lost
- https://github.com/containous/traefik/releases does not have a traefic yaml to download?! so I found the
traefic-ds.ymlin the tar bal
- completely confusing as there is nothing to diff.
download.yamlwhere does it come from? oh and where does the name
traefic-ds.rule.yamlcome from? I think

- now it really becomes confusing... created but get deprecation warning (not expected or described in lab)

- when I do
ip aI get like 10 entries. I think I must be either one of these two (but I've tried all of them). the 192.168.10.100 is my assigned IP for the virtualbox of "master" so the other one?

not the expected outcome...
try a few things:
$ kubectl get svc NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE kubernetes ClusterIP 10.96.0.1 <none> 443/TCP 6h17m nginx ClusterIP 10.100.6.73 <none> 443/TCP 5h55m registry ClusterIP 10.99.23.233 <none> 5000/TCP 5h55m secondapp LoadBalancer 10.104.28.125 <pending> 80:32000/TCP 17m thirdpage NodePort 10.102.188.72 <none> 80:32298/TCP 74m
curl on the IPs for secondapp and thirdpage work, but those do not go through the ingress so not on the right track but lets look onwards
- with this command:
$ kubectl exec -it thirdpage-<tab> -- sed -i 's/Welcome to nginx!/third page/g' /usr/share/nginx/html/index.html $ curl 10.102.188.72 <!DOCTYPE html> <html> <head> <title>third page</title> ...
- does not work?
- only works if I use the "external"
http://node-ip:8080/dasboard/where node-ip is the ip of the worker it runs on... There are no providers?
I'm quite lost at this point. I have done the exercises a couple of times now and even reset my whole cluster to make sure of a clean situation, but no dice :-) any help would be much appreciated.
