docker not found in $PATH

✗ CLUSTER STARTUP


docker not found in $PATH


FAILED ✗

clstr couldn’t find a docker binary on your PATH. Install a Docker-compatible runtime: the Docker Engine on Linux, or OrbStack or Docker Desktop on Mac.

After installing, verify the CLI is available:

Terminal window
$ docker --version
Docker version 29.4.0, build 9d7ad9f

If this fails in the same terminal where you ran clstr, your shell hasn’t picked up the updated PATH yet. Run source ~/.zshrc (or your shell’s equivalent) and try again. Once docker --version succeeds, make sure the daemon is running, then retry clstr test.
