Q.3 Can you give an example of a successful deployment you have led?
DevOps Engineer’s generic example of a well-executed deployment
A client’s new web-based application was successfully deployed under the direction of a DevOps Engineer. The application was built with a microservices architecture and then deployed to Kubernetes in the cloud.
The DevOps Engineer used a blue-green deployment approach to limit service disruptions. To do this, a second, identical production environment was set up alongside the live one, and the updated application was rolled out there while the live one continued to run as usual.
To better understand how an application is performing, the DevOps Engineer sets up monitoring and logging systems. Because of this, the team was able to spot and fix any problems that cropped up during the deployment with relative ease.
After a successful deployment, the application experienced no downtime. The team was able to release the updated version of the application to users without a hitch, and they were given access to useful data from the monitoring and logging systems.
Q.4 How do you handle rollbacks and failure recovery?
There are several ways to handle rollbacks and failure recovery in Git:
- Reverting a commit: If you want to undo a specific commit, you can use the “git revert” command. This command creates a new commit that undoes the changes made in the previous commit. The original commit is not deleted, but it is no longer part of the current branch.
- Resetting a branch: If you want to completely undo all the changes made in a branch, you can use the “git reset” command. This command discards all the commits in a branch and resets the branch to a specific commit. Be aware that this command permanently deletes commits, so use it carefully.
- Checking out an older commit: If you want to go back to an older version of the code, you can use the “git checkout” command. This command allows you to switch to a specific commit, creating a new branch with that commit as the starting point.
- Branching: Git allows you to create branches, which allow you to work on multiple versions of a codebase simultaneously. This can be useful for experimenting with new features or bug fixes without affecting the main branch. If something goes wrong, you can simply discard the branch without affecting the main codebase.
- Backups: Regularly creating backups of your Git repositories is a good practice to ensure that your codebase can be restored in case of any disaster or deletion. This can be done by creating a clone of the repository, or by using a Git hosting service like GitHub or GitLab.
- Continuous Integration and Deployment tools like Jenkins, Travis, CircleCI, etc can also help in handling rollbacks and failure recovery by doing automated testing and deployments, providing notifications and alerting the teams in case of any failure, and providing an easy way to rollback to the previous versions.
Q.5 How do you ensure security in a DevOps environment?
