Docker//Lifecycle
- `--rm` creates ephemeral "use-and-discard" containers — perfect for one-shot tools like key generation.
--rm creates ephemeral "use-and-discard" containers — perfect for one-shot tools like key generation.
Key gen pattern: docker run --rm -v $(pwd):/data besu ... export-address — run, save output, self-destruct.
-d (detach): container runs in background, returns control to terminal.
-it (interactive + tty): attaches your terminal to the container — opposite of -d.
Persistent nodes use -d without --rm; tooling uses --rm without -d.
