Do I need Kubernetes for microservices?
Even when introducing services and microservices, you may not need or want to start with Kubernetes. For example, Kubernetes does not include robust built-in tools for securing pods, nodes and clusters, and deploying Kubernetes clusters across a multi-cloud environment can add a lot of complexity.
What should I learn first Docker or Kubernetes?
I would suggest you to first learn Docker rather than skipping to Kubernetes, There is confusion related to Docker swarm and its similarities with Kubernetes. Kubernetes is providing ecosystem for shipping of Docker containers.
What should I learn before Kubernetes?
Kubernetes is designed on top of container technology. There are some container technologies available like Docker, Podman, Crio-O. So before starting with kubernetes you should know one of the container technology in depth. It will help you to connect the concepts properly.
When should I start using Kubernetes?
If you have transitioned or are looking to transition to a microservice architecture then Kubernetes will suit you well because it’s likely you’re already using software like Docker to containerize your application. If you’re unable to meet customer demands due to slow development time, then Kubernetes might help.
When you should not use Kubernetes?
Unless you have a service-oriented application with an architecture that requires multiple services to communicate with one another-say an e-commerce project, with one service that handles the products, another that handles the cart, and another that handles payments.
Should I learn Docker or Kubernetes 2021?
Hello folks, if you are looking to learn some in-demand software tools in 2021 to improve your profile then you have come to the right place. Along with Docker, if there is another tool or technology which has caught software developers’ attention in recent times then it must be Kubernetes.
Should I learn 2021 Docker?

| Centralized monitoring agent * | 2 GB | 0.7 |
Do you really need Kubernetes?
Kubernetes is useful if you are dealing with many containers and require some automation of the steps when starting them. So, unless you have a large microservice environment, Kubernetes is unlikely to bring much added value. Probably, it is not needed or suited for your case and you should not invest in it.
Do you need Kubernetes to start with?
Even when introducing services and microservices, you may not need or want to start with Kubernetes. Kubernetes excels at running and scaling pods of related service and microservice containers. However, there are aspects of adopting Kubernetes that are easy to overlook at first.
What are microservices in Kubernetes and how do they work?
Microservices have emerged as a popular development practice for teams who want to release complex systems quickly and reliably. Kubernetes is a natural platform for microservices as it can handle the orchestration required to deploy many instances of many individual microservices.
Why are operators so popular in Kubernetes?
In the world of Kubernetes, Operators have quickly become a popular pattern far beyond their initial use for encoding deep operational knowledge about running stateful applications and services like Prometheus.
What are the exceptions to Kubernetes Service Resource Step?
The exceptions are loadgenerator, which has no service, and frontend, which includes an additional load balancer service that exposes the microservice to public traffic. The additional load balancer service can be deployed with the Deploy Kubernetes service resource step.
