Name

nix flake archive - copy a flake and all its inputs to a store

Synopsis

nix flake archive [option...] flake-url

Copy the dwarffs flake and its dependencies to a binary cache:
```
# nix flake archive --to file:///tmp/my-cache dwarffs
```
Fetch the dwarffs flake and its dependencies to the local Nix store:
```
# nix flake archive dwarffs
```
Print the store paths of the flake sources of NixOps without fetching them:
```
# nix flake archive --json --dry-run nixops
```
Upload all flake inputs to a different machine for remote evaluation
```
# nix flake archive --to ssh://some-machine
```
On the remote machine the flake can then be accessed via its store path. That's computed like this:
```
# nix flake metadata --json | jq -r '.path'
```

Copy a flake and all its inputs to a store. This is useful i.e. to evaluate flakes on a different host.

--dry-run

Show what this command would do without doing it.
--json

Produce output in JSON format, suitable for consumption by another program.
--no-check-sigs

Do not require that paths are signed by trusted keys.
--no-pretty

Print compact JSON output on a single line, even when the output is a terminal. Some commands may print multiple JSON objects on separate lines.
```
              See `--pretty`.
```

Print multi-line, indented JSON output for readability.

              Default: indent if output is to a terminal.

              This option is only effective when `--json` is also specified.

--arg name expr

Pass the value expr as the argument name to Nix functions.
--arg-from-file name path

Pass the contents of file path as the argument name to Nix functions.
--arg-from-stdin name

Pass the contents of stdin as the argument name to Nix functions.
--argstr name string

Pass the string string as the argument name to Nix functions.
--debugger

Start an interactive environment if evaluation fails.
--eval-store store-url

The URL of the Nix store to use for evaluation, i.e. to store derivations (.drv files) and inputs referenced by them.
--impure

Allow access to mutable paths and repositories.
--include / -I path

Add path to search path entries used to resolve lookup paths

This option may be given multiple times.

Paths added through -I take precedence over the nix-path configuration setting and the NIX_PATH environment variable.
--override-flake original-ref resolved-ref

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

--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.

DEPRECATED

Use --no-use-registries instead.
--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.
--output-lock-file flake-lock-path

Write the given lock file instead of flake.lock within the top-level flake.
--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.

DEPRECATED

Use nix flake update instead.
--reference-lock-file flake-lock-path

Read the given lock file instead of flake.lock within the top-level flake.
--update-input input-path

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

DEPRECATED

Use nix flake update instead.

--debug

Set the logging verbosity level to 'debug'.
--log-format format

Set the format of log output; one of raw, internal-json, bar or bar-with-logs.
--print-build-logs / -L

Print full build logs on standard error.
--quiet

Decrease the logging verbosity level.
--verbose / -v

Increase the logging verbosity level.

--help

Show usage information.
--offline

Disable substituters and consider all previously downloaded files up-to-date.
--option name value

Set the Nix configuration setting name to value (overriding nix.conf).
--refresh

Consider all previously downloaded files out-of-date.
--repair

During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths.
--version

Show version information.

Note

See man nix.conf for overriding configuration settings with command line flags.
