Name
nix flake archive - copy a flake and all its inputs to a store
Synopsis
nix flake archive [option...] flake-url
Examples
- 
Copy the dwarffsflake and its dependencies to a binary cache:# nix flake archive --to file:///tmp/my-cache dwarffs
- 
Fetch the dwarffsflake 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-machineOn 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'
Description
Copy a flake and all its inputs to a store. This is useful i.e. to evaluate flakes on a different host.
Options
- 
Show what this command would do without doing it. 
- 
Produce output in JSON format, suitable for consumption by another program. 
- 
Do not require that paths are signed by trusted keys. 
- 
--tostore-uriURI of the destination Nix store 
Common evaluation options
- 
--argname exprPass the value expr as the argument name to Nix functions. 
- 
--arg-from-filename pathPass the contents of file path as the argument name to Nix functions. 
- 
--arg-from-stdinnamePass the contents of stdin as the argument name to Nix functions. 
- 
--argstrname stringPass the string string as the argument name to Nix functions. 
- 
Start an interactive environment if evaluation fails. 
- 
--eval-storestore-urlThe URL of the Nix store to use for evaluation, i.e. to store derivations ( .drvfiles) and inputs referenced by them.
- 
Allow access to mutable paths and repositories. 
- 
--include/-IpathAdd path to search path entries used to resolve lookup paths This option may be given multiple times. Paths added through -Itake precedence over thenix-pathconfiguration setting and theNIX_PATHenvironment variable.
- 
--override-flakeoriginal-ref resolved-refOverride the flake registries, redirecting original-ref to resolved-ref. 
Common flake-related options
- 
Commit changes to the flake's lock file. 
- 
--inputs-fromflake-urlUse the inputs of the specified flake as registry entries. 
- 
Don't allow lookups in the flake registries. DEPRECATED Use --no-use-registriesinstead.
- 
Do not allow any updates to the flake's lock file. 
- 
Do not write the flake's newly generated lock file. 
- 
--output-lock-fileflake-lock-pathWrite the given lock file instead of flake.lockwithin the top-level flake.
- 
--override-inputinput-path flake-urlOverride a specific flake input (e.g. dwarffs/nixpkgs). This implies--no-write-lock-file.
- 
Recreate the flake's lock file from scratch. DEPRECATED Use nix flake updateinstead.
- 
--reference-lock-fileflake-lock-pathRead the given lock file instead of flake.lockwithin the top-level flake.
- 
--update-inputinput-pathUpdate a specific flake input (ignoring its previous entry in the lock file). DEPRECATED Use nix flake updateinstead.
Logging-related options
- 
Set the logging verbosity level to 'debug'. 
- 
--log-formatformatSet the format of log output; one of raw,internal-json,barorbar-with-logs.
- 
--print-build-logs/-LPrint full build logs on standard error. 
- 
Decrease the logging verbosity level. 
- 
--verbose/-vIncrease the logging verbosity level. 
Miscellaneous global options
- 
Show usage information. 
- 
Disable substituters and consider all previously downloaded files up-to-date. 
- 
--optionname valueSet the Nix configuration setting name to value (overriding nix.conf).
- 
Consider all previously downloaded files out-of-date. 
- 
During evaluation, rewrite missing or corrupted files in the Nix store. During building, rebuild missing or corrupted store paths. 
- 
Show version information. 
Note
See
man nix.conffor overriding configuration settings with command line flags.
