There are a few issues with the deployment file that you have provided:
1. The `template` section is missing a `labels` field. This field is required to specify the labels that are applied to the pods created by the deployment.
2. The `containers` field is missing a hyphen at the beginning of the line. It should be written as `- name: nginx` instead of `—name: nginx`.
3. The `ports` field is missing a hyphen at the beginning of the line. It should be written as `- containerPort: 80` instead of `—containerPort: 80`.
4. The `image` field is missing the image tag. It should be written as `image: nginx:` instead of just `image: nginx`.
Here's the corrected deployment file:
Copy code
`apiVersion: apps/v1 kind: Deployment metadata: name: nginx-deployment labels: app: web spec: selector: matchLabels: app: web replicas: 5 strategy: type: RollingUpdate template: metadata: labels: app: web spec: containers: - name: nginx image: nginx: ports: - containerPort: 80`
