What is a Docker namespace?
Docker uses a technology called namespaces to provide the isolated workspace called the container. When you run a container, Docker creates a set of namespaces for that container. Each aspect of a container runs in a separate namespace and its access is limited to that namespace.
Is RKT better than Docker?
The short answer is that rkt now provides a viable alternative to Docker. It has a more Linux-like architecture. And a strong competitor will keep the monopolist sharp.
What is CoreOS RKT?
CoreOS rkt (pronounced rocket) is a containerization software engine for running application workloads in isolation from the underlying infrastructure. It is a major competitor to the Docker container engine. CoreOS rkt is based on the Application Container Image (ACI) as defined by the App Container spec (appc).
What is the difference between RHEL and CoreOS?
CoreOS is designed for security, consistency, and reliability. Red Hat Enterprise Linux includes military-grade security technologies—from network firewall control to secure containers for application isolation—to prevent intrusions and protect your data.
What is the lifecycle of Docker container?

We can deploy many containers simultaneously on a given host. In this blog, we will talk about Docker Container Lifecycle Management.
What is Cgroups and namespaces?
Namespaces and cgroups are the building blocks for containers and modern applications. Namespaces provide isolation of system resources, and cgroups allow for fine‑grained control and enforcement of limits for those resources. Containers are not the only way that you can use namespaces and cgroups.

What is rkt container?
rkt is an application container engine developed for modern production cloud-native environments. rkt implements a modern, open, standard container format, the App Container (appc) spec, but can also execute other container images, like those created with Docker.
Is rkt supported by Kubernetes?
Kubernetes runs all applications in containers. In the default setup, this is performed using the Docker engine, but Kubernetes also features support for using rkt as its container runtime backend. This allows a Kubernetes cluster to leverage some of rkt’s security features and native pod support.
Is CoreOS rkt open source?
Both Docker and CoreOS rkt are free, open source offerings, with various paid-for enterprise offerings consisting primarily of value-added services and support.
