Update Traefik
When Coolify shows Traefik patch update available or New Traefik minor version available, update the proxy by changing its image version in the UI, saving the configuration, and restarting the proxy.
Check compatibility first
Open the Traefik releases and review the release notes between your current version and the version you want to use. Follow any linked migration guides to check whether configuration options have changed or been removed.
Users with Coolify's default proxy configuration can usually update without additional configuration changes. If you have modified the default configuration, check your custom command flags, environment variables, routing rules, middleware, and dynamic files against the new version before updating. Major-version upgrades can require additional migration steps.
Keep a copy of the current configuration and image version so you can restore them if needed. Restarting the proxy briefly interrupts traffic to resources routed through it.
Open the proxy configuration
Open Servers, select the server, then open Proxy > Configuration.
Change the image version
In Configuration file, find image under services.traefik and replace its tag with the version you reviewed. For example:
services:
traefik:
image: traefik:v3.7.14
# Keep the rest of your existing configuration.The version above is an example. Use the release you selected and keep the rest of your configuration, applying any changes required by its release notes. Use an explicit version tag so future updates are deliberate.
Edits made directly to /data/coolify/proxy/docker-compose.yml do not sync back into the UI once Coolify has a saved proxy configuration. A restart through Coolify can overwrite disk-only edits.
Save and restart
Select Save changes, then Restart Proxy to apply the new image version.
Wait for the proxy to report that it is running. Check Proxy > Logs for startup or configuration errors, then open your application domains and verify HTTPS and any custom routing or middleware.
If the new version fails, restore the previous image tag and configuration in the UI, save, and restart the proxy again.
