Kodekloud Kubernetes Challenge 3 solution | Vote App | Redis | Postgresql DB | Deployment | service

 Question : Deploy the given architecture to vote namespace

1. Create a  service: name = vote-service

     port = '5000'

     targetPort = '80'

     nodePort= '31000'

     service endpoint exposes deployment 'vote-deployment'

2. Create a deployment: name = 'vote-deployment'

     image = 'kodekloud/examplevotingapp_vote:before'

     status: 'Running'

3. New Service, name = 'redis'

     port: '6379'

     targetPort: '6379'

     type: 'ClusterIP'

     service endpoint exposes deployment 'redis-deployment'

4. Create new deployment, name: 'redis-deployment'

     image: 'redis:alpine'

     Volume Type: 'EmptyDir'

     Volume Name: 'redis-data'

     mountPath: '/data'

     status: 'Running'

5. Create new deployment. name: 'worker'

     image: 'kodekloud/examplevotingapp_worker'

     status: 'Running'

6. Create new service: 'db'

     port: '5432'

     targetPort: '5432'

     type: 'ClusterIP'

7. Create new deployment. name: 'db-deployment'

     image: 'postgres:9.4' and add the env: 'POSTGRES_HOST_AUTH_METHOD=trust'

     Volume Type: 'EmptyDir'

     Volume Name: 'db-data'

     mountPath: '/var/lib/postgresql/data'

     status: 'Running'

8. Create new deployment, name: 'result-deployment'

     image: 'kodekloud/examplevotingapp_result:before'

     status: 'Running'

9. Create new service, name: 'result-service'

    

    port: '5001'

    targetPort: '80'

    NodePort: '31001'

Solution: 

1. Create new Namespace vote & validate the status

root@controlplane ~ ➜  kubectl create namespace vote namespace/vote created root@controlplane ~ ➜  root@controlplane ~ ➜  kubectl get namespace NAME              STATUS   AGE default           Active   36m kube-node-lease   Active   36m kube-public       Active   36m kube-system       Active   36m vote              Active   2s root@controlplane ~ ➜

2.  Created  YAML  manifest files with all the parameters, Kindly clone repo or you can copy from GitLab 

git clone https://gitlab.com/nb-tech-support/devops.git

 ( Refer Below Video for more clarity )

3.  Create new db-deployment & validate the status

root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/db-deployment.yml deployment.apps/db-deployment created root@controlplane ~ ➜  root@controlplane ~ ➜  kubectl get deployment -n vote NAME            READY   UP-TO-DATE   AVAILABLE   AGE db-deployment   1/1     1            1           27s root@controlplane ~ ➜

4.  Create new db-service & validate the status

root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/db-service.yml service/db created root@controlplane ~ ➜  kubectl get svc -n vote NAME   TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)    AGE db     ClusterIP   10.108.140.177   <none>        5432/TCP   11s root@controlplane ~ ➜

5.  Create new redis-deployment &  services 

root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/redis-deployment.yml deployment.apps/redis-deployment created root@controlplane ~ ➜  root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/redis-service.yml service/redis created root@controlplane ~ ➜

6.  Create worker deployment

root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/worker.yml deployment.apps/worker created root@controlplane ~ ➜

7.  Create result deployment & service

root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/result-deployment.yml deployment.apps/result-deployment created root@controlplane ~ ➜  root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/result-service.yml service/result-service created root@controlplane ~ ➜

8.  Create vote deployment & service

root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/vote-deployment.yml deployment.apps/vote-deployment created root@controlplane ~ ➜  root@controlplane ~ ➜  kubectl apply -f devops/kubernetes-challenges/challenge-3/vote-service.yml service/vote-service created root@controlplane ~ ➜

9.  Validate the complete deployment

root@controlplane ~ ➜  kubectl get all -n vote NAME                                     READY   STATUS    RESTARTS   AGE pod/db-deployment-7f94c7d956-9nh69       1/1     Running   0          12m pod/redis-deployment-69957f749-5fcs6     1/1     Running   0          3m3s pod/result-deployment-6b49cd76bc-6fjgz   1/1     Running   0          2m39s pod/vote-deployment-8d7f7bcdc-p8w7z      1/1     Running   0          2m22s pod/worker-64d7c4db94-f842s              1/1     Running   0          2m46s   NAME                     TYPE        CLUSTER-IP       EXTERNAL-IP   PORT(S)          AGE service/db               ClusterIP   10.108.140.177   <none>        5432/TCP         10m service/redis            ClusterIP   10.110.206.89    <none>        6379/TCP         2m57s service/result-service   NodePort    10.106.219.112   <none>        5001:31001/TCP   2m30s service/vote-service     NodePort    10.111.78.1      <none>        5000:31000/TCP   2m11s   NAME                                READY   UP-TO-DATE   AVAILABLE   AGE deployment.apps/db-deployment       1/1     1            1           12m deployment.apps/redis-deployment    1/1     1            1           3m4s deployment.apps/result-deployment   1/1     1            1           2m40s deployment.apps/vote-deployment     1/1     1            1           2m22s deployment.apps/worker              1/1     1            1           2m46s   NAME                                           DESIRED   CURRENT   READY   AGE replicaset.apps/db-deployment-7f94c7d956       1         1         1       12m replicaset.apps/redis-deployment-69957f749     1         1         1       3m3s replicaset.apps/result-deployment-6b49cd76bc   1         1         1       2m40s replicaset.apps/vote-deployment-8d7f7bcdc      1         1         1       2m22s replicaset.apps/worker-64d7c4db94              1         1         1       2m46s  root@controlplane ~ ➜
