## Configuration
|
||||||
|
|
||||||
|
The lbrycrd container comes with a default configuration you can use for
|
||||||
|
production. Extra configuration is optional.
|
||||||
|
|
||||||
|
The container includes a `start` script that offers a flexible configuration
|
||||||
|
style. It allows you to mount your own `lbrycrd.conf` file, or use environment
|
||||||
|
variables, or a mix of both.
|
||||||
|
|
||||||
|
### Environment variables
|
||||||
|
|
||||||
|
The environment variables override the values in the mounted config file. If no
|
||||||
|
mounted config file exists, these variables are used to create a fresh config.
|
||||||
|
|
||||||
|
* `PORT` - The main lbrycrd port
|
||||||
|
* `RPC_USER` - The rpc user
|
||||||
|
* `RPC_PASSWORD` - The rpc user's password
|
||||||
|
* `RPC_ALLOW_IP` - the subnet that is allowed rpc access
|
||||||
|
* `RPC_PORT` - The port to bind the rpc service to
|
||||||
|
* `RPC_BIND` - The ip address to bind the rpc service to
|
||||||
|
|
||||||
|
|
||||||
|
### Example run commands
|
||||||
|
|
||||||
|
Running the default configuration:
|
||||||
|
|
||||||
|
```
|
||||||
|
docker run --rm -it -e RUN_MODE=default lbry/lbrycrd:linux-x86_64-production
|
||||||
|
```
|
||||||
|
|
||||||
|
Running with RPC password changed:
|
||||||
|
|
||||||
|
```
|
||||||
|
docker run --rm -it -e RUN_MODE=default -e RPC_PASSWORD=hunter2 lbry/lbrycrd:linux-x86_64-production
|
||||||
|
```
|
||||||
|
|
||||||
|
Running with a config file but with the RPC password still overridden:
|
||||||
|
|
||||||
|
```
|
||||||
|
docker run --rm -it -v /path/to/lbrycrd.conf:/etc/lbry/lbrycrd.conf -e RUN_MODE=default -e RPC_PASSWORD=hunter2 lbry/lbrycrd:linux-x86_64-production
|
||||||
|
```
