[Solved] - name: Push image run: docker push myapp:1.0 - name: Deploy run: kubectl set image deployment/myapp myapp=myapp:1.0What will happen after this pipeline runs successfully? | Docker

Docker - in CI/CD

Given this snippet in a CI/CD pipeline YAML file:

steps:
  - name: Build image
    run: docker build -t myapp:1.0 .
  - name: Push image
    run: docker push myapp:1.0
  - name: Deploy
    run: kubectl set image deployment/myapp myapp=myapp:1.0

What will happen after this pipeline runs successfully?

AThe Kubernetes deployment will update to use the new Docker image tagged 1.0

BThe Docker image will be deleted from the registry

CThe deployment will roll back to the previous image

DThe Docker image will only be built locally without pushing

Step-by-Step Solution

Solution:

Step 1: Analyze build and push steps
The pipeline builds the image tagged 'myapp:1.0' and pushes it to the registry.
Step 2: Analyze deployment step
The command updates the Kubernetes deployment to use the new image 'myapp:1.0'.
Final Answer:
The Kubernetes deployment will update to use the new Docker image tagged 1.0 -> Option A
Quick Check:
Build + push + deploy = update deployment [OK]

Quick Trick: Build, push, then deploy updates the app [OK]

Common Mistakes:

Assuming image is only local, not pushed
Thinking deployment rolls back automatically
Confusing deployment update with image deletion
