Whether you’re looking for the best host for containers or building containerized applications, Clear Linux* OS offers extreme versatility, scalability, and hardened security. On Clear Linux OS, hosting a container is as simple as adding the containers-basic bundle.
So what makes Clear Linux OS an optimal platform for hosting containers?
In contrast to other Linux distros, Clear Linux OS is lean and can host multiple containers without requiring many unnecessary packages. Default installation is minimal, so there’s no need to strip the OS of extra services or software. Check out the recommended system requirements.
Clear Linux OS employs the principle of lightweight installation, reducing risk and addressing a basic security concern: “The more software you have installed, the larger the attack surface.” Because Clear Linux OS offers two software updates per day, your version of Clear Linux OS will always carry the latest updates from the Linux kernel, as well as our developers’ security fixes.
- Software updates
Clear Linux OS allows you to run the exact same software for all container hosts in a cluster. Clear Linux OS manages software using bundles. This means administrators need only check a single version number to track all software on the system.
With a lightning-fast boot time, Clear Linux OS containers can be provisioned on-demand. Faster performance also means more containers per host, allowing for cost savings. Clear Linux OS is one of the most performance-driven Linux distros for running workloads in the cloud. Clear Linux OS ranks faster on several benchmarks when tested on Intel® Core i9 and Intel® Xeon® processors.
Clear Linux OS and Kubernetes*
As an open source container orchestration system, Kubernetes* automates deployment, scaling, maintenance, and scheduling of application containers across clusters of nodes. Nodes in a cluster can run your applications or workloads. Kubernetes offers integration with Docker* runc or CRI+O runtime environments.
Installing Kubernetes on a Clear Linux node is simple. To get started, you need only add one bundle: cloud-native-basic. You can also leverage Kubernetes with Docker by adding the bundle: containers basic. To get started, check out our tutorials:
Clear Linux OS and Kata Containers*
“Kata Containers* is a new open source project building extremely lightweight virtual machines that seamlessly plug into the container ecosystem ,” per the Kata Containers website. With Clear Linux OS, adding Kata support means adding one bundle: containers-virt, simplifying integration.
Kata Containers provide a dedicated kernel, enabling isolation of network, I/O, and memory, as well as support for industry standards such as OCI container format, Kubernetes* CRI, and legacy virtualization.

Clear Linux OS as Container Image
What are the advantages of running Clear Linux OS as the container image?
The Clear Linux OS single version number simplifies container management, ensuring consistency of software versions at deploy and run time.
Optimized Performance: Clear Linux OS containers give access to libraries Intel® Advanced Vector Extensions (Intel® AVX) and Intel® Advanced Vector Extensions 2 (Intel® AVX2), which use the most advanced instruction set based on your system hardware.
Stability: Over 100K downloads.
