Rollback a Deployment in Kubernetes

Task :

This morning the Nautilus DevOps team rolled out a new release for one of the applications. Recently on of the customers logged a complaint which seems to be about a bug related to the recent release. Therefore, the team wants to rollback the recent release.

There is a deployment named nginx-deployment; roll it back to the previous revision.

Note: The kubectl utility on jump_host has been configured to work with the kubernetes cluster.

Solutions:

Cek terlebih dahulu status deploymentnya

# kubectl rollout status deployment/nginx-deployment

Apabila sudah selesai, rollback menggunakan command berikut :

# kubectl rollout undo deployment/nginx-deployment
