Holochain Revision: v0.0.115 Nov 10, 2021
Lair Keystore Revision: v0.0.9 Nov 4, 2021
Expects a DNA built with HDK v0.0.115
An alternative Holochain conductor binary useful for quick startup and inclusive handling of key generation and dna installation for a single DNA app.
```bash holochain-runner 0.0.33 wrapped Holochain Conductor with Status Update events and a good SIGTERM kill switch.
USAGE:
holochain-runner [OPTIONS]
FLAGS: -h, --help Prints help information -V, --version Prints version information
OPTIONS:
--admin-ws-port
ARGS:
app_id and app_ws_port
will be overridden if an existing
configuration is found at this path [default: databases]
```
datastore-path is most important. If existing persisted Holochain conductor files
are found in the given directory, it will simply re-use the admin_ws_port app_ws_port app_id and dnas from that configuration. Otherwise, it will create that directory, and setup your configuration as specified.
keystore-path can point to an empty folder, or a pre-existing keystore, as long as that keystore uses a compatible keystore format. If there is a private key in the existing keystore it will use that to install the DNA and app, if there is none, it will generate one automatically on the first run.
It uses structopt to make a configurable service. For a more advanced application using shutdown signal, and StateSignal listeners, you can see it in use in the Acorn Holochain application.
In either case,
it will log this to the console when the interfaces are all ready and the app installed or running:
EMBEDDED_HOLOCHAIN_IS_READY
It will clearly log its configuration to the console.
RUST_LOG environment variable can be set to get details logs from Holochain. Those logs are by default suppressed.
It may emit events, based on event types in an enum StateSignal. These will be logged to the console
so that you can track the internal state and progress.
It looks like:
rust
pub enum StateSignal {
// will be only one or the other of these
IsFirstRun,
IsNotFirstRun,
// are sub events after IsFirstRun
CreatingKeys,
RegisteringDna,
InstallingApp,
EnablingApp,
AddingAppInterface,
// Done/Ready Event, called when websocket interfaces and
// everything else is ready
IsReady,
}
This library is currently by default pointed at the https://bootstrap-staging.holo.host node discovery service, but can be overridden.
