Worker-App-Pod not running

Kubernetes
#1

I am on the Kubernetes for Begginers course and when trying to make the deployment of the microservices, the worker-app-pod is not being able to run. First i had to add the Postgres_Host_Auth_Method env to postgres pod, but even then, the worker pod is left as ContainerCreating and then to ImagePullBackOff

The yml is as follow:

apiVersion: v1
kind: Pod
metadata:
name: worker-app-pod
labels:
name: worker-app-pod
app: demo-voting-app
spec:
containers:
- name: worker-app
image: kodekloud/examplevotingapp_worker:v2

Hello @pablol,
Please follow these full steps to know what you have missed and try again :

Note: We will create deployments again so please before following the steps, Run kubectl delete deployment --all to delete old deployments and avoid any conflicts.

  1. Run git clone https://github.com/mmumshad/example-voting-app-kubernetes-v2.git
  2. Run cd example-voting-app-kubernetes-v2/
  3. Run vim postgres-deployment.yml and modify it’s content as below then save and exit.

Note: It’s a new update from Postgres.

kind: Deployment
metadata:
  name: postgres-deployment
  labels:
    app: demo-voting-app
spec:
  replicas: 1
  selector:
    matchLabels:
      name: postgres-pod
      app: demo-voting-app
  template:
    metadata:
      name: postgres-pod
      labels:
        name: postgres-pod
        app: demo-voting-app
    spec:
      containers:
      - name: postgres
        image: postgres:9.4
        env:
        - name: POSTGRES_USER
          value: postgres
        - name: POSTGRES_PASSWORD
          value: postgres
        - name: POSTGRES_HOST_AUTH_METHOD
          value: trust
        ports:
        - containerPort: 5432
  1. Run kubectl create -f . if you create deployments for the first time, if you created the same deployments before Run kubectl apply -f . .
  2. Run kubectl get service to get the exposed ports.

For example if the output of the command as above you can accces the voting app by hitting One_of_the_worker_nodes_IP:32733 on your browser and the same for the resulting app >> One_of_the_worker_nodes_IP:30013.

Note: The voting application only accepts one vote per client. It does not register votes if a vote has already been submitted from a client.

Hope this helps!

Hello @Ayman the deployment works correctly. The error i am getting is on the previous lecture, where the deploy is from the pods files.
