Deployment resources within Kubernetes have simplified container deployments, and they are one of the most used Kubernetes resources. Deployments manage ReplicaSets, and they help create multiple deployment strategies by appropriately manipulating them to produce the desired effect.
Surprisingly, deployments only have two Strategy types:
RollingUpdate is the default strategy where Kubernetes creates a new ReplicaSet and starts scaling the new ReplicaSet up and simultaneously scaling the old ReplicaSet down, the
Recreate strategy scales the old ReplicaSet to zero and creates a new one with the desired replicas immediately.
That does not limit Kubernetes’ ability, though, for more advanced deployments. There are more fine-grain controls on the deployment specification that can help us implement multiple deployment patterns and strategies. Let’s look at possible scenarios, when to use them, and how they look with hands-on examples.
Our original Kubernetes tool list was so popular that we've curated another great list of tools to help you improve your functionality with the platform.
At some point we've all said the words, "But it works on my machine." It usually happens during testing or when you're trying to get a new project set up. Sometimes it happens when you pull down changes from an updated branch.
DevOps and Cloud computing are joined at the hip, now that fact is well appreciated by the organizations that engaged in SaaS cloud and developed applications in the Cloud. During the COVID crisis period, most of the organizations have started using cloud computing services and implementing a cloud-first strategy to establish their remote operations. Similarly, the extended DevOps strategy will make the development process more agile with automated test cases.

This is the era of containerization and orchestration where the majority of the applications are following the trend of running on a container which is further deployed in a Kubernetes cluster.
