Upgrade Image Process
From time to time we need to update the images that RKE2 depends on. This document serves as a how-to for that process. The following steps are laid out in order.
Update Image
Create a new release in the image repository (eg image-build-etcd). This is done by specifying the tag version you want built from whatever upstream this repo is using. An image will be built and pushed to Docker Hub.
Update RKE2
The following example files have references that will need to be updated in the respective locations for etcd. Replace the found version with the desired version.
- build-images:
${REGISTRY}/rancher/hardened-etcd:${ETCD_VERSION}-build20220413 - scripts/version.sh:
ETCD_VERSION=${ETCD_VERSION:-v3.4.13-k3s1}
Some images may include a build date as part of the tag in format -buildYYYYmmdd. Trivy image scans may periodically fail as vulnerabilities are found in the base operating system. Re-tagging an image with the current build date should force an update of the base operating system and may help to resolve vulnerabilities found in image scans.
