In Tines Cloud deployments you can now create custom runtimes that run on your Tines Command Runner over a tunnel. To do so, upload a ZIP with your dependencies in Settings → Custom runtimes, choose Docker as the execution environment.

Then select that runtime on a Run Script action using the Docker implementation and a tunnel.

Unlike Cloud runtimes, which run in Tines-managed Lambda and can use pre-built Python environments, Docker runtimes run on your own Command Runner. That means you bundle everything in the ZIP and execute inside your network — useful when you need private packages, system libraries, or the same environment you already use for self-hosted Run Script. For more information on creating custom runtimes, check out these docs.
