Erik Arvstedt 03db1a61b1 lnd, joinmarket: don't write to secrets dir Keeping the secrets dir read-only is more simple and robust. - lnd seed mnemonic creation and joinmarket wallet creation can be run as the regular service user instead of root. - It is easier to switch to a third-party secrets deployment method in the future. Don't create a seed mnemonic for lnd when a wallet exists. This avoids creating unused mnemonics and helps simplifying the migration command in `versioning.nix`.		2021-03-15 18:50:15 +01:00

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