Featured Reviews

Felipe Giffu - PeerSpot reviewer
An operational system, similar to Linux where you can run your applications inside containers
With CoreOS, you can run your applications inside containers. For example, if you have an application that needs to run on Linux, you can create and install a container. However, it's important to note that you don't install CoreOS inside a container; CoreOS is the host operating system that manages containers. When you mentioned using Nacula as part of your CI/CD pipeline, it means your application is deployed and managed automatically through the CI/CD process. Containers are used to deploy your application within this pipeline, but CoreOS does not run inside these containers. Instead, CoreOS is the base operating system that supports and manages these containers.

Enables seamless local Kubernetes development and quick deployment to the cloud
Rancher Desktop provides support for Kubernetes setup on local machines. It allows us to run Kubernetes as per our requirement, and the desktop application offers a good UI. We use Rancher Desktop for local development, testing APIs locally, and it helps to seamlessly publish to the cloud. This makes it a valuable tool for developers.
