func CheckDaemonRunning ¶

func CheckDaemonRunning() error

CheckDaemonRunning verifies the Docker daemon is reachable, returning an actionable error when it is not. Creating the client is lazy — it succeeds even when Docker is stopped — so commands that need Docker (local kind clusters, the local registry, mirrors, the DNS resolver, docker workshops) call this as a preflight. Without it a stopped daemon surfaces a cryptic failure deep inside kind ("docker ps ... exit status 1") or the Docker SDK.
