Installing the FIM demo using Helm

If you'd prefer to install the FIM demo against a real Kubernetes cluster, you can use the Helm chart in this directory. For example,

$ helm install hello hello-server

or, if you want to install the demo in the foobar namespace

$ kubectl create namespace foobar
$ helm install -n foobar hello hello-server

The Helm install will tell you how to connect to the "Hello, world" service endpoint.

NAME: hello
LAST DEPLOYED: Sat Jun 18 20:20:28 2022
NAMESPACE: foobar
STATUS: deployed
REVISION: 1
TEST SUITE: None
NOTES:
You can find the hello-service URL by running:
  export SERVICE_IP=$(kubectl get svc --namespace foobar hello-service --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
  echo http://$SERVICE_IP:80

Following the instructions will generate output like

$ export SERVICE_IP=$(kubectl get svc --namespace foobar hello-service --template "{{ range (index .status.loadBalancer.ingress 0) }}{{.}}{{ end }}")
$ echo http://$SERVICE_IP:80
http://10.100.132.67:80

Then,

$ curl http://10.100.132.67:80
Hello, world!

You can use kubectl commands to interact with the containers in the pod

$ kubectl exec -it -n foobar hello-server -c hello-server -- bash
hellouser@hello-server:~$ ls -l

hellouser@hello-server:~$ exit
exit
$ kubectl exec -it -n foobar hello-server -c fim -- ash
