Exam CKS Topic 5 Question 52 Discussion

Solution (Step by Step) :
1. Install 'image-patchers:
- Install the 'image-patcher' tool on your system or within your Kubernetes cluster. 'image-patcher' is a tool for patching container images without rebuilding thenm It allows you to modify the container image's filesystem and update libraries directly.
2. Identify the Vulnerable Library:
- Use a vulnerability scanner like Trivy to identify the specific vulnerable library within the container image.
3. Patch the Vulnerable Library:
- Use 'image-patcher' to apply the security patch to the vulnerable library within the container image.
- You can use the 'image-patcher apply' command with the patch file and tne container image name to apply the patch.
4. Create a Patched Image:
- 'image-patcher' Will generate a new, patched container image. This patched image will contain the updated library with the security fix applied.
5. Push the Patched Image to a Registry:
- Push the patched image to your private container registry for use in deployments.
6. Update the Deployment
- Update the "my-app" deployment configuration to use the newly created patched image from your private registry.
7. Validate the Patch:
- After updating the deployment, verify that the patch has been successfully applied by running a vulnerability scan on the running container.
