flk export

Export the current flake configuration to Docker, Podman, or JSON.

flk export --format docker
flk export --format podman
flk export --format json
flk export --format docker --profile backend

Options

  • -f, --format <FORMAT>: Export format — docker, podman, or json (required)
  • -p, --profile <PROFILE>: Target a specific profile instead of the default

Formats

Docker

Builds a Nix-based Docker image from the flake and loads it into the local Docker daemon.

  • Requires Docker to be installed and running
  • The image is built via nix build .#docker-<profile> and loaded with docker load
  • Output image is stored at .flk/result before loading

Podman

Same as Docker but uses Podman instead.

  • Requires Podman to be installed and running
  • Built via nix build .#podman-<profile> and loaded with podman load

JSON

Serializes the parsed flake configuration to a flake.json file in the project root.

  • Includes all profiles, packages, environment variables, and inputs
  • Useful for debugging, CI pipelines, or integrating with other tools
  • Does not require Docker or Podman

Notes

  • Docker and Podman exports use --impure for Nix builds
  • Uses standard profile resolution when --profile is not specified
