Warning: This program is experimental and its interface is subject to change.

Name

nix bundle - bundle an application so that it works outside of the Nix store

Synopsis

nix bundle [option…] installable

Examples

•   Bundle Hello:

    # nix bundle nixpkgs#hello
    # ./hello
    Hello, world!

•   Bundle a specific version of Nix:

    # nix bundle github:NixOS/nix/e3ddffb27e5fc37a209cfd843c6f7f6a9460a8ec
    # ./nix --version
    nix (Nix) 2.4pre20201215_e3ddffb

•   Bundle a Hello using a specific bundler:

    # nix bundle --bundler github:NixOS/bundlers#toDockerImage nixpkgs#hello
    # docker load < hello-2.10.tar.gz
    # docker run hello-2.10:latest hello
    Hello, world!

Description

nix bundle, by default, packs the closure of the installable into a single self-extracting executable. See the bundlers homepage <https://github.com/NixOS/bundlers> for more details.

    Note

    This command only works on Linux.

Flake output attributes

If no flake output attribute is given, nix bundle tries the following flake output attributes:

•   bundlers.<system>.default

If an attribute name is given, nix run tries the following flake output attributes:

•   bundlers.<system>.<name>

Bundlers

A bundler is specified by a flake output attribute named bundlers.<system>.<name>. It looks like this:

    bundlers.x86_64-linux = rec {
      identity = drv: drv;
      blender_2_79 = drv: self.packages.x86_64-linux.blender_2_79;
      default = identity;
    };

A bundler must be a function that accepts an arbitrary value (typically a derivation or app definition) and returns a derivation.

Options

•   --bundler flake-url
    Use a custom bundler instead of the default (github:NixOS/bundlers).

•   --out-link / -o path
    Override the name of the symlink to the build result. It defaults to the base name of the app.

Common evaluation options:

•   --arg name expr
    Pass the value expr as the argument name to Nix functions.

•   --argstr name string
    Pass the string string as the argument name to Nix functions.

•   --eval-store store-url
    The Nix store to use for evaluations.

•   --impure
    Allow access to mutable paths and repositories.

•   --include / -I path
    Add path to the list of locations used to look up <...> file names.

•   --override-flake original-ref resolved-ref
    Override the flake registries, redirecting original-ref to resolved-ref.

Common flake-related options:

•   --commit-lock-file
    Commit changes to the flake’s lock file.

•   --inputs-from flake-url
    Use the inputs of the specified flake as registry entries.

•   --no-registries
    Don’t allow lookups in the flake registries. This option is deprecated; use --no-use-registries.

•   --no-update-lock-file
    Do not allow any updates to the flake’s lock file.

•   --no-write-lock-file
    Do not write the flake’s newly generated lock file.

•   --override-input input-path flake-url
    Override a specific flake input (e.g. dwarffs/nixpkgs). This implies --no-write-lock-file.

•   --recreate-lock-file
    Recreate the flake’s lock file from scratch.

•   --update-input input-path
    Update a specific flake input (ignoring its previous entry in the lock file).

Options that change the interpretation of installables:

•   --derivation
    Operate on the store derivation rather than its outputs.

•   --expr expr
    Interpret installables as attribute paths relative to the Nix expression expr.

•   --file / -f file
    Interpret installables as attribute paths relative to the Nix expression stored in file. If file is the character -, then a Nix expression will be read from standard input.
