Usage
doctl harness-runtime exec <session> -- <command> [args...] [flags]Description
Run one command in a session’s sandbox and print its output.
Drives the sandbox directly rather than through its agent, so it works on a bare sandbox created with --template sandbox as well as on a managed-agent session.
Separate the guest command from doctl’s own flags with --, or flags meant for the guest (ls -la) are parsed as doctl flags.
Guest stdout and stderr pass through unchanged and the guest’s exit code becomes doctl’s, so this composes in pipelines and && chains. Each call is independent: there is no shell session between calls, so cd does not carry over — use --workdir, or run a shell explicitly (-- sh -c 'cd src && make').
Output is buffered until the command finishes, and capped at 1 MiB per stream. With -o json the full response is emitted instead of the raw streams.
