fluxcd/flux2 v0.21.0

on GitHub

This release comes with ECDSA as the default SSH key algorithm used by flux bootstrap and all the other commands that generate SSH keys. This change was imposed by GitHub that is no longer accepting RSA SHA-1 SSH keys.

To rotate your SSH deploy keys for the repositories bootstrapped with Flux:

• download the Flux CLI v0.21.0 binary
• delete the deploy key secret from your cluster kubectl -n flux-system delete secret flux-system
• using the Flux CLI v0.21.0 rerun flux bootstrap github with the same arguments as before
• Flux will generate a ecdsa-sha2-nistp384 SSH key and will update the deploy key on GitHub
