Caution

Promtail is now deprecated and will enter into Long-Term Support (LTS) beginning Feb. 13, 2025. This means that Promtail will no longer receive any new feature updates, but it will receive critical bug fixes and security fixes. Commercial support will end after the LTS phase, which we anticipate will extend for about 12 months until February 28, 2026. End-of-Life (EOL) phase for Promtail will begin once LTS ends. Promtail is expected to reach EOL on March 2, 2026, afterwards no future support or updates will be provided. All future feature development will occur in Grafana Alloy.

If you are currently using Promtail, you should plan your migration to Alloy. The Alloy migration documentation includes a migration tool for converting your Promtail configuration to an Alloy configuration with a single command.

I haven't used Promtail so I could not lend a hand here— it would be great if someone takes this task to implement it to the playbook! 🙂

I created the role, but I don’t have the bandwidth to thoroughly test it right now and open the PR. Contributions are very welcome.
