advanced lb creation

This example creates a deployment named echoheaders on your cluster, which will run a single replica of the echoserver container, listening on port 8080 (http) and 8443 (https). Then create a Service that exposes our new application to the Internet over an Outscale Load Balancer Unit on http and https using certificates.

  • Create ns
$ kubectl create namespace advanced-lb
namespace/advanced-lb created
  • Create bucket for logs
$ aws s3 mb s3://ccm-examples  --endpoint https://osu.eu-west-2.outscale.com
make_bucket: ccm-examples
  • Deploy the pods to get the certificate
$ kubectl apply  -f examples/advanced-lb/specs/deploy.yaml
deployment.apps/echoheaders created
  • Get certificate generated by the pod by deploying the application , which a simple server that responds with the http headers it received, along with the Loadbalancer
$ kubectl get pods -n advanced-lb
NAME                           READY   STATUS    RESTARTS   AGE
echoheaders-5465f4df9d-sw487   1/1     Running   0          2d23h

$ kubectl exec -n advanced-lb  echoheaders-5465f4df9d-sw487 ls /certs 
certificate.crt
privateKey.key

mkdir -p certs ;  kubectl cp advanced-lb/echoheaders-5465f4df9d-sw487:/certs ./certs/

  • Upload 'UploadServerCertificate' the certs copied previously under ./certs and retrieve it ORN id

  • Update service yaml by setting the certificate ssl ORN ID and the loadBalancerSourceRanges and then apply it

$ OSC_ORN_ID="The ID" ; \
  sed -i "s@OSC_ORN_ID@\"${OSC_ORN_ID}\"@g" ./examples/simple-lb/specs/svc.yaml

$ MY_CIDR=`curl ifconfig.io`"/32" ; \
  sed -i "s@MY_CIDR@\"${MY_CIDR}\"@g" ./examples/simple-lb/specs/svc.yaml

$ kubectl apply  -f examples/advanced-lb/specs/svc.yaml
service/echoheaders-lb-advanced-public created
	
$ kubectl get svc -n advanced-lb
NAME                             TYPE           CLUSTER-IP     EXTERNAL-IP                                                             PORT(S)                      AGE
echoheaders-lb-advanced-public   LoadBalancer   10.32.29.197   ad51051c7a133489591adc0e1fbec049-832076221.eu-west-2.lbu.outscale.com   80:31174/TCP,443:31249/TCP   84m
  • Wait for the lb to be ready and then check it is running and forwarding traffic
$ curl -k  https://ad51051c7a133489591adc0e1fbec049-832076221.eu-west-2.lbu.outscale.com/

notice: !!! You need to fix certificate name to match the outscale.com domain
  • Cleanup resources:
$ kubectl delete  -f examples/advanced-lb/specs/
