How was your work with Kubernetes and Docker structured? Did developers handle it themselves or DevOps?

In our practice, working with Kubernetes and Docker was organized jointly: developers created and maintained Docker images of their applications, wrote Dockerfiles and basic deployment manifests. DevOps engineers handled more complex configuration of Kubernetes clusters, CI/CD pipelines, monitoring, and scaling.

This approach allows developers to quickly test and update their services in containers, while DevOps ensures the stability and reliability of the infrastructure. For example, a developer writes a Dockerfile and Helm charts for their service, and DevOps sets up automatic deployment via Jenkins or GitLab CI, as well as monitors the cluster status and logs.
