nix3-flake-archive - Man Page

copy a flake and all its inputs to a store

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

Synopsis

nix flake archive [option…] flake-url

# nix flake archive --to file:///tmp/my-cache dwarffs

# nix flake archive dwarffs

# nix flake archive --json --dry-run nixops

# 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`.

            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.
