You can upgrade rke2 by using the installation script, or by manually installing the binary of the desired version.
Note: Upgrade the server nodes first, one at a time. Once all servers have been upgraded, you may then upgrade agent nodes.
Upgrades performed via the installation script or using our automated upgrades feature can be tied to different release channels.
latest channel is the only available channel. Once we have more releases and need to distinguish between the most recent release and the most stable release, we will add a stable channel and set it as the default.
Upgrade rke2 Using the Installation Script¶
To upgrade rke2 from an older version you can re-run the installation script using the same flags, for example:
curl -sfL https://get.rke2.io | sh -
If you want to upgrade to a newer version in a specific channel (such as latest) you can specify the channel:
curl -sfL https://get.rke2.io | INSTALL_RKE2_CHANNEL=latest sh -
If you want to upgrade to a specific version you can run the following command:
curl -sfL https://get.rke2.io | INSTALL_RKE2_VERSION=vX.Y.Z-rc1 sh -
