nuts service executable #######################
Nuts executable for Nuts service space. The idea behind this executable that it includes different 'engines'. It can be configured through command line options to enable or disable an engine. This will allow for a single process that runs all service space components, ideal for development. For production a choice can be made for multiple instances of the same engine (by starting this executable multiple times), allowing for a more fine grained control and better scalability. The executable exposes the REST (or other) services from the different engines. This also makes it easier to apply a particular security mechanism.

Dependencies
Go version => 1.13 is required.
Running tests
Tests can be run by executing
.. code-block:: shell
go test ./...
Building
just use go build.
README
The readme is auto-generated from a template and uses the documentation to fill in the blanks.
.. code-block:: shell
./generate_readme.sh
This script uses rst_include which is installed as part of the dependencies for generating the documentation.
Documentation
The configuration options documentation is generated from the actual flags provided by the engines. When engines are updated, this documentation should be regenerated to reflect any changes in provided flags. To regenerate the configuration documentation run the following command from the project root:
.. code-block:: shell
make update-docs
To build the documentation, you'll need python3, sphinx and a bunch of other stuff. See :ref:nuts-documentation-development-documentation
The documentation can be build by running
.. code-block:: shell
/docs $ make html
The resulting html will be available from docs/_build/html/index.html
Configuration
The Nuts-go library contains some configuration logic which allows for usage of configFiles, Environment variables and commandLine params transparently. If a Nuts engine is added as Engine it'll automatically work for the given engine. It is also possible for an engine to add the capabilities on a standalone basis. This allows for testing from within a repo.
The parameters follow the following convention:
$ nuts --parameter X is equal to $ NUTS_PARAMETER=X nuts is equal to parameter: X in a yaml file.
Or for this piece of yaml
.. code-block:: yaml
nested:
parameter: X
is equal to $ nuts --nested.parameter X is equal to $ NUTS_NESTED_PARAMETER=X nuts
Config parameters for engines are prepended by the engine.ConfigKey by default (configurable):
.. code-block:: yaml
engine:
nested:
parameter: X
is equal to $ nuts --engine.nested.parameter X is equal to $ NUTS_ENGINE_NESTED_PARAMETER=X nuts
Options
The following options can be configured:
======================================== =================================================================================== ================================================================================================================================================================================ Key Default Description ======================================== =================================================================================== ================================================================================================================================================================================
address localhost:1323 Address and port the server will be listening to
configfile nuts.yaml Nuts config file
identity Vendor identity for the node, mandatory when running in server mode. Must be in the format: urn:oid:1.3.6.1.4.1.54851.4:
mode server Mode the application will run in. When 'cli' it can be used to administer a remote Nuts node. When 'server' it will start a Nuts node. Defaults to 'server'.
strictmode false When set, insecure settings are forbidden.
verbosity info Log level (trace, debug, info, warn, error)
Auth
auth.actingPartyCn The acting party Common name used in contracts
auth.address localhost:1323 Interface and port for http server to bind to
auth.enableCORS false Set if you want to allow CORS requests. This is useful when you want browsers to directly communicate with the nuts node.
auth.irmaConfigPath path to IRMA config folder. If not set, a tmp folder is created.
auth.irmaSchemeManager pbdf The IRMA schemeManager to use for attributes. Can be either 'pbdf' or 'irma-demo'
auth.mode server or client, when client it does not start any services so that CLI commands can be used.
auth.publicUrl Public URL which can be reached by a users IRMA client
auth.skipAutoUpdateIrmaSchemas false set if you want to skip the auto download of the irma schemas every 60 minutes.
ConsentBridgeClient
cbridge.address http://localhost:8080 API Address of the consent bridge
ConsentStore
cstore.address localhost:1323 Address of the server when in client mode
cstore.connectionstring :memory: Db connectionString
cstore.mode server or client, when client it uses the HttpClient
Crypto
crypto.fspath ./ when file system is used as storage, this configures the path where keys are stored (default .)
crypto.keysize 2048 number of bits to use when creating new RSA keys
crypto.storage fs storage to use, 'fs' for file system (default)
Events octopus
events.autoRecover false Republish unfinished events at startup
events.connectionstring file::memory:?cache=shared db connection string for event store
events.incrementalBackoff 8 Incremental backoff per retry queue, queue 0 retries after 1 second, queue 1 after {incrementalBackoff} * {previousDelay}
events.maxRetryCount 5 Max number of retries for events before giving up (only for recoverable errors
events.natsPort 4222 Port for Nats to bind on
events.purgeCompleted false Purge completed events at startup
events.retryInterval 60 Retry delay in seconds for reconnecting
Network
network.address Interface and port for http server to bind to, defaults to global Nuts address.
network.bootstrapNodes Space-separated list of bootstrap nodes (<host>:<port>) which the node initially connect to.
network.certFile PEM file containing the certificate this node will identify itself with to other nodes. If not set, the Nuts node will attempt to load a TLS certificate from the crypto module.
network.certKeyFile PEM file containing the key belonging to this node's certificate. If not set, the Nuts node will attempt to load a TLS certificate from the crypto module.
network.grpcAddr :5555 Local address for gRPC to listen on.
network.mode server or client, when client it uses the HttpClient
network.nodeID Instance ID of this node under which the public address is registered on the nodelist. If not set, the Nuts node's identity will be used.
network.publicAddr Public address (of this node) other nodes can use to connect to it. If set, it is registered on the nodelist.
network.storageConnectionString file:network.db SQLite3 connection string to the database where the network should persist its documents.
