How to give runners a static IP

A third-party service requires IP allowlisting and hosted runner IPs change constantly.

A third-party service requires IP allowlisting and hosted runner IPs change constantly.

Why it happens

Hosted runners draw from large, rotating cloud IP ranges.

How to fix it

  1. Use BYOC runners behind a NAT gateway with an Elastic IP
  2. Allowlist that single address on the third-party service
  3. Avoid allowlisting whole cloud ranges — it defeats the purpose
