simple-internal

Simple 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. Then create a Service that exposes our new application to the internal vpc over an Outscale Load Balancer unit (LBU) with schema setted to internal.

• Add kubernetes.io/role/internal-elb to private subnet

• Create ns

$ kubectl create namespace simple-internal
namespace/simple-internal created

• Create bucket for logs. Be sure to change bucket name (they are unique per region).

$ aws s3 mb s3://ccm-examples  --endpoint https://osu.eu-west-2.outscale.com
make_bucket: ccm-examples

• Adapt service.beta.kubernetes.io/aws-load-balancer-access-log-s3-bucket-name annotation in specs/svc.yaml with your bucket name.

• Deploy the application, which a simple server that responds with the http headers it received, along with the Loadbalancer

$ kubectl apply  -f examples/simple-internal/specs/
	deployment.apps/echoheaders created
	service/echoheaders-lb-internal created
	
$ kubectl get all -n simple-internal

• Validate the LB was created and the endpoint is available

$ kubectl get service  -n simple-internal echoheaders-lb-internal
NAME                    TYPE           CLUSTER-IP     EXTERNAL-IP                                                             PORT(S)        AGE

• Check logs under buckets created and its content

aws s3 ls --recursive s3://ccm-examples/ --endpoint https://osu.eu-west-2.outscale.com

• Wait for the lb to be ready and then check it is running and forwarding traffic
