parameters sanity check

[gurvindersingh]

I faced issue when deploying traefik on K8s using deployment file with args as

  --web
  --kubernetes
  --logLevel=DEBUG
  --acme
  --acme.ondemand=true
  --acme.email=test@example.com
  --acme.storagefile=acme.json
  --acme.entrypoint=https
  --defaultentrypoints=http,https
  --entryPoints="Name:http Address::80 Redirect.EntryPoint:https"
  --entryPoints="Name:https Address::443 TLS"

With the above mentioned params, traefik itself starts fine, but when it got ingress object information from K8s. it give errors as

time="2016-07-12T07:36:37Z" level=warning msg="Error loading load balancer method '<nil>' for backend 2048.example.com: Invalid method, using default. Using default wrr." 
time="2016-07-12T07:36:37Z" level=debug msg="Configuration received from provider kubernetes: {\"backends\":{\"2048.example.com\":{\"servers\":{\"http://192.168.0.147:80\":{\"url\":\"http://192.168.0.147:80\",\"weight\":1},\"http://192.168.0.88:80\":{\"url\":\"http://192.168.0.88:80\",\"weight\":1},\"http://192.168.249.139:80\":{\"url\":\"http://192.168.249.139:80\",\"weight\":1}},\"loadBalancer\":{\"method\":\"wrr\"}}},\"frontends\":{\"2048.example.com\":{\"entryPoints\":[\"http\",\"https\"],\"backend\":\"2048.example.com\",\"routes\":{\"2048.example.com\":{\"rule\":\"Host:2048.example.com\"}},\"passHostHeader\":true,\"priority\":0}}}"

time="2016-07-12T07:36:37Z" level=error msg="Skipping frontend 2048.example.com..."

The issue is related to params passed with quotes, so if I removed the quotes around entryPoints parameters, traefik works as expected. So it would be good to have a sanity check on passed params during traefik starting process.

Hello!

The current implementation of the kubernetes provider does a sanity check, then skips the offending ingress on error, logging a message for debugging purposes.

I will close this ticket for this reason.

If you have further issues, please open a new ticket!
