Previously, Docker was auto-detected when the CLI was installed or a candidate Unix socket existed. Neither check verified that the Docker API was responsive. A similar check was done when auto-detecting Podman in the past, but was replaced in1f07bf04with a probe of candidate Podman sockets instead. This change applies the functional API probing approach introduced for Podman in1f07bf04to Docker. It also makes Docker driver initialization use the same socket-selection mechanism as Docker auto-detection instead of Bollard’s local defaults. This means the previously auto-detectable Docker socket paths $HOME/.docker/run/docker.sock and $XDG_RUNTIME_DIR/docker.sock will actually be usable. When no working compute driver can be auto-detected, the gateway exits early with a message saying as much: > configuration error: no compute driver configured and auto-detection found no > suitable driver; set --drivers or OPENSHELL_DRIVERS to kubernetes, podman, > docker, or vm This makes for a better user experience when installing OpenShell without an available supported compute driver.
