Name

nix-store --serve - serve local Nix store over SSH

Synopsis

nix-store --serve [--write]

Description

The operation --serve provides access to the Nix store over stdin and stdout, and is intended to be used as a means of providing Nix store access to a restricted ssh user.

The following flags are available:

  • --write

    Allow the connected client to request the realization of derivations. In effect, this can be used to make the host act as a remote builder.

{{#include ./opt-common.md}}

{{#include ../opt-common.md}}

{{#include ../env-common.md}}

Examples

To turn a host into a build server, the authorized_keys file can be used to provide build access to a given SSH public key:

$ cat <<EOF >>/root/.ssh/authorized_keys
command="nice -n20 nix-store --serve --write" ssh-rsa AAAAB3NzaC1yc2EAAAA...
EOF
