Is there experience in deploying and updating clusters?

Yes, I have experience deploying and updating clusters, including Kubernetes and Docker Swarm.

Deployment involves preparing the infrastructure, configuring network policies, setting up load balancers, and deploying applications with scalability and fault tolerance in mind.

Cluster updates are usually performed with minimal downtime, using strategies like rolling update or blue-green deployment. In Kubernetes, this is achieved by updating the Deployment with control over the number of pods updated simultaneously.

Example command for updating an image in Kubernetes:

kubectl set image deployment/my-app my-app-container=myrepo/my-app:v2

Automating processes with CI/CD pipelines for safe and repeatable updates is also important.
