hoprd-config-tool

Tool to generate HOPRd identity, configuration, and docker-compose files from a single input where all required data is specified.

Installation

➜ pip(3) install (-U) hoprd-config-tool

Usage

To generate the required ressources (identities, configurations and docker-compose files) from a config file, run the following command:

➜ python -m hoprd-config-tool --params .config/network_1.toml

You can specify the root folder where identity and configuration files will be generated by appending the optional parameter --folder <FOLDER> which by default is set to ./.hoprd-nodes/.

The generated docker compose file follows the default naming: docker-compose.yml

Custom Docker networks

If you need the generated compose file to reference custom networks (for example to attach the services to an existing external network) you can define them in your configuration file under the networks key, using the same syntax as in a regular docker-compose.yml file:

[networks.default]
name = "hoprd-network1"
external = true

The contents of this section are copied verbatim into the rendered compose file and every generated service automatically references all declared networks.

Using tagged values in TOML

The TOML params file can express the YAML tags used by the generated configuration (for example !AutoFunding, !AutoRedeeming, or !ClosureFinalizer) by embedding the tag in the array-of-table header:

[[config.hopr.strategy.strategies.AutoFunding]]
funding_amount = "500 xDAI"
min_stake_threshold = "100 HOPR"

The tool converts those entries into the appropriate YAML objects before rendering the final .cfg.yaml files, so the output format remains unchanged.

Naming nodes with surnames

Each entry in the [[nodes]] section can optionally embed the node's surname directly into the table header to differentiate nodes within the same params file:

[[nodes.alpha]]
safe_address = "SAFE_ADDRESS_1"
...

The surname in the header is converted to a slug (letters, numbers, and dashes only) and used in every generated file path and docker-compose service name. If a node omits the surname (for example by sticking with a plain [[nodes]] entry) the tool falls back to the numeric index, preserving the existing behavior.
