# Install Kata Containers on CentOS

> **Notes:**
>
> - Kata Containers packages are available for [CentOS\*](https://www.centos.org)
>   version 7 (currently `x86_64` only).
>
> - If you are installing on a system that already has Clear Containers or `runv` installed,
>   first read [the upgrading document](../Upgrading.md).
>
> - If you do not want to copy or type all these instructions by hand, you can use the
>   [`kata-manager`](https://github.com/kata-containers/tests/blob/master/cmd/kata-manager/kata-manager.sh)
>   script to install the packaged system including your chosen container
>   manager. Alternatively, you can generate a runnable shell script from
>   individual documents using the
>   [`kata-doc-to-script`](https://github.com/kata-containers/tests/blob/master/.ci/kata-doc-to-script.sh) script.

1. Install the Kata Containers components with the following commands:

   > **Note:** This installation channel is not secure since the repository currently
   > redirects download URLs to `http`.

   ```bash
   $ source /etc/os-release
   $ sudo yum -y install yum-utils
   $ sudo -E VERSION_ID=$VERSION_ID yum-config-manager --add-repo "http://download.opensuse.org/repositories/home:/katacontainers:/release/CentOS_${VERSION_ID}/home:katacontainers:release.repo"
   $ sudo -E yum -y install kata-runtime kata-proxy kata-shim
   ```
