Kubernetes

Instructions for a Vanilla install of Minikube

1. To expose the application as an load balance service, we have to give our pod a namespace

kubectl create namespace forgerock

2. To build the configmap for this enviroment, run the command below, pointing to the file, stock.txt. This will create the configmap called stock.yaml in yaml format, the file will not appear in your directory but is stored in kubernetes

kubectl create configmap stock.yaml --from-file stock.txt -o yaml

3. To build the secret config for this enviroment, run the command below, pointing to the file that contains the base64 version of the api_key.txt

echo -n "your_api_key_here" | base64 > secret.yaml

4. Apply both to your kubernetes instance

kubectl apply -f secret.yaml
kubectl apply -f stock.yaml

5. With this namespace created, we can apply the manifest file, forgerock_deploy.yaml, to the namespace

kubectl apply -f forgerock_deploy.yaml -n forgerock

6. We can forward our port to see if our pod deployment was successful

kubectl port-forward deployment/forgerock-deploy -n forgerock 8081:8081

7. Navigate to localhost:8081 to see the flask application is successfully forwarding correctly

8. Run the forgerock_ingress.yaml with the command below to create a stable network for the pod, with the same namespace

kubectl apply -f forgerock_ingress.yaml -n forgerock

9. You can verify it is running if your output is similar to mine with the same command

MBP-041150:kubernetes julie.brady$ kubectl get svc -w
NAME         TYPE        CLUSTER-IP   EXTERNAL-IP   PORT(S)   AGE
kubernetes   ClusterIP   10.96.0.1    <none>        443/TCP   64m
