History

Erik Arvstedt f7c2133250 add flake support This change is fully backwards compatible. We continue to use the standard non-flake evaluation mode in our examples and internal tooling until the flakes design has stabilized. 'clightning-plugins = pkgs.recurseIntoAttrs' in pkgs/default.nix is needed by flake-utils.lib.flattenTree in flake.nix. It transforms the packages in `clightning-plugins` to top-level packages named like `clightning-plugins/summary`. (The flake attr `packages` must be a non-nested attrset of derivations.)		2021-08-26 12:45:10 +02:00

Examples

The easiest way to try out nix-bitcoin is to use one of the provided examples.

git clone https://github.com/fort-nix/nix-bitcoin
cd nix-bitcoin/examples/
nix-shell

The following example scripts set up a nix-bitcoin node according to configuration.nix and then shut down immediately. They leave no traces (outside of /nix/store) on the host system.
By default, configuration.nix enables bitcoind and clightning.

./deploy-container.sh creates a NixOS container.
This is the fastest way to set up a node.
Requires: Nix, a systemd-based Linux distro and root privileges
./deploy-qemu-vm.sh creates a QEMU VM.
Requires: Nix
./deploy-krops.sh creates a QEMU VM and deploys a nix-bitcoin configuration to it using krops.
Requires: Nix
./deploy-container-minimal.sh creates a container defined by minimal-configuration.nix that doesn't use the secure-node.nix preset. Also shows how to use nix-bitcoin in an existing NixOS config.
Requires: Nix, a systemd-based Linux distro and root privileges

Run the examples with option --interactive or -i to start a shell for interacting with the node:

./deploy-qemu-vm.sh -i

Tests

The internal test suite is also useful for exploring features.
The following run-tests.sh commands leave no traces (outside of /nix/store) on the host system.

git clone https://github.com/fort-nix/nix-bitcoin
cd nix-bitcoin/test

# Run a node in a VM. No tests are executed.
./run-tests.sh vm
systemctl status bitcoind

# Run a Python test shell inside a VM node
./run-tests.sh debug
print(succeed("systemctl status bitcoind"))
run_test("bitcoind")

# Run a node in a container. Requires systemd and root privileges.
./run-tests.sh container
c systemctl status bitcoind

# Explore a single feature
./run-tests.sh --scenario electrs container

# Run a command in a container
./run-tests.sh --scenario '{
  services.clightning.enable = true;
  nix-bitcoin.nodeinfo.enable = true;
}' container --run c nodeinfo

See run-tests.sh for a complete documentation.

Real-world example

Check the server repo for https://nixbitcoin.org to see the configuration of a nix-bitcoin node that's used in production.

The commands in shell.nix allow you to locally run the node in a VM or container.

Flakes

Flakes make it easy to include nix-bitcoin in an existing NixOS config. The flakes example shows how to use nix-bitcoin as an input to a system flake.

Run nix run or nix run .#vm from the nix-bitcoin root directory to start an example nix-bitcoin node VM. This command is defined by the nix-bitcoin flake (in flake.nix).
