lc setup (removed)¶

The lc setup command no longer exists. The global configuration file (~/.lightcone/config.yaml) is now created automatically the first time you run any lc command — there is nothing to run manually.

Global config file¶

~/.lightcone/config.yaml is created with these defaults on first use:

container:
  runtime: auto

Edit the file by hand to change the container runtime:

$EDITOR ~/.lightcone/config.yaml

`container.runtime` values¶

Value	Behavior
`auto` (default)	Pick the first usable runtime in `(podman, docker, podman-hpc)`. Skips docker if its daemon isn't reachable. Falls back to `none` if nothing's available.
`docker`	Pin to docker. Errors at run time if the binary isn't on PATH.
`podman`	Pin to podman.
`podman-hpc`	Pin to podman-hpc — typical on NERSC Perlmutter login nodes.
`none`	Explicit opt-out from containers. Recipes run on the host.

Setting runtime: none explicitly silences the provenance warning that lc run shows when auto falls back to none. (See lc run.)
