Hosting Containers

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?

  • Manageability

    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.  

  • Security

    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.  
  • Performance

    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 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:

  • Provides the same security as a virtual machine. Kata containers have their own lightweight OS and dedicated kernel, providing isolation of network, I/O and memory. Kata Containers can also utilize hardware-enforced isolation with virtualization VT extensions

  • Supports industry standards including OCI container format, Kubernetes* CRI interface, as well as legacy virtualization technologies

  • Eliminates the requirement for nesting containers inside full blown VMs

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.
