Hi everyone,
We are currently investigating a bug report regarding Traefik upgrades from revisions < 3.0.8 to revisions > 3.0.8.
Current Recommendation: We advise holding off on refreshing/upgrading Traefik for the time being, unless you are already running a version higher than 3.0.8.
-
The Risk: This bug can cause service disruption if your Traefik deployment relies on a non-automatic certificate provider (for example,
manual-tls-certificates). In this specific scenario, Traefik may unexpectedly fall back on its default self-signed certificate. -
How you can help: If you are running this setup please drop a comment in this thread. We are actively working on a fix/remediation and need visibility into a wide range of deployments to ensure it’s robust.
Thank you for your patience while we sort this out! We will keep you updated here.
