Configuration

Command line options

Please note, there are numerous options available that can be deployed to override the configuration on the runtime whilst starting the Lisk Core.

To overwrite config options from the command line, execute the following commands below:

  • Pass options as ENV variables

  • Pass options as flags

LISK_NETWORK=[network] LISK_CONFIG_FILE=[config-path] LISK_ADDRESS=[address] LISK_WS_PORT=[port] pm2 start lisk
The flag options are deprecated. Therefore it is recommend to pass the options as ENV variables. 
node dist/index.js -p [port] -a [address] -c [config-path] -n [network]

You can pass devnet (default), alphanet, betanet, testnet, or mainnet for the [network] option.

All ENV variables are restricted with a operating system constraint of ENV variable maximum length.

Comma-separated lists will replace the original config values. For example, If LISK_PEERS is specified, the original peers.list specific to the network will be replaced completely.

Each of these options listed below can be appended in the command line:
