Lab 1 Solution - Pod Creation¶

yoda-service-pod.yaml

apiVersion: v1
kind: Pod
metadata:
  name: yoda-service
  namespace: web
  labels:
    app: yoda
spec:
  containers:
    - name: nginx
      image: quay.io/nginx/nginx-unprivileged:1.29
      command: ["nginx"]
      args: ["-g", "daemon off;"]
      ports:
        - containerPort: 8080

oc new-project web
oc apply -f yoda-service-pod.yaml
oc get pods -n web

Expected output

NAME           READY   STATUS    RESTARTS   AGE
yoda-service   1/1     Running   0          20s

Tip

command overrides the image's ENTRYPOINT, and args overrides its CMD. The -g "daemon off;" directive keeps nginx in the foreground. If it forked into the background, the container's main process would exit and the Pod would restart over and over.
