Kata Manager

Warning:

  • Kata Manager will not work for Fedora 31 and higher since those distribution versions only support cgroups version 2 by default. However, Kata Containers currently requires cgroups version 1 (on the host side). See kata-containers#927 for further details.

Note:

We recommend users install Kata Containers using official distribution packages, where available.

The kata-manager.sh script automatically installs and configures Kata Containers and containerd.

This scripted method installs the latest versions of Kata Containers and containerd. However, be aware of the following before proceeding:

  • Packages will not be automatically updated

    Since a package manager is not being used, it is your responsibility to ensure these packages are kept up-to-date when new versions are released to ensure you are using a version that includes the latest security and bug fixes.

  • Potentially untested versions or version combinations

    This script installs the newest versions of Kata Containers and containerd from binary release packages. These versions may not have been tested with your distribution version.

If you still wish to continue, but prefer a manual installation, see the containerd installation guide.

Install a minimal Kata Containers system

By default, the script will attempt to install Kata Containers and containerd, and then configure containerd to use Kata Containers. However, the script provides a number of options to allow you to change its behaviour.

Note:

Before running the script to install Kata Containers, we recommend that you review the available options.

Show available options

To show the available options without installing anything, run:

$ bash -c "$(curl -fsSL https://raw.githubusercontent.com/kata-containers/kata-containers/main/utils/kata-manager.sh) -h"

To install Kata Containers only

If your system already has containerd installed, to install Kata Containers and only configure containerd, run:

$ bash -c "$(curl -fsSL https://raw.githubusercontent.com/kata-containers/kata-containers/main/utils/kata-manager.sh) -o"

To install Kata Containers and containerd

To install and configure a system with Kata Containers and containerd, run:

$ bash -c "$(curl -fsSL https://raw.githubusercontent.com/kata-containers/kata-containers/main/utils/kata-manager.sh)"
