Can you tell about the last complex task you faced and how you solved it?

One of the complex tasks in DevOps was automating the deployment of microservices in Kubernetes considering different environments (dev, staging, production). The problem was that configurations varied greatly, and I needed to avoid duplication and errors during updates.

Solution:

• Used Helm charts for configuration management and templating.
• Created separate values files for each environment.
• Configured CI/CD pipeline to substitute the appropriate values file depending on the branch.
• Conducted testing on staging before deploying to production.

This significantly simplified deployment process and reduced errors during updates.
