Can Docker be used without Kubernetes?

Can Docker be used without Kubernetes? Both yes and no are the responses. Kubernetes is not a comprehensive solution by itself. You can't manage containers without having containers in the first place, hence orchestration is dependent on a container runtime.

Is Docker superior to Kubernetes?

Kubernetes is the greatest option when it comes to orchestrating big distributed applications with hundreds of connected microservices, including databases, secrets, and external dependencies, despite the fact that Docker Swarm is an alternative in this field.

IaaS or PaaS, is Docker?

What is taking Docker's place?

BuildKit. BuildKit is a second-generation image-building Moby project that you may be familiar with if you use a more recent version of Docker. Faster builds are achieved using BuildKit's parallel build processing, which enhances performance. A daemon is used to power both BuildKit and Docker.
