You can override any setting from crun show <network>
output by passing -e

For example, let's check the settings for lava_testnet
crun show lava_testnet
hain_id: lava-testnet-2
netname: lava_testnet
repo: https://github.com/lavanet/lava.git
version: v2.1.1
binary: lavad
genesis: https://storage.mellifera.network/lava_testnet/genesis.json
addressbook: https://storage.mellifera.network/lava_testnet/addrbook.json
snapshot: https://storage.mellifera.network/lava_testnet/snapshot_latest.tar.lz4
go_version: go1.20.14
cosmos_folder: '.lava'
...etc
Any of these settings can be overridden with -e
flag.
Here is few examples of usage:
- Install lava_testnet from state_sync
# Check modified settings
crun show lava_testnet -e "install_from=state_sync"
# Run crun to Install lava_testnet from state_sync
crun install lava_testnet -e "install_from=state_sync"
- Install
lava_testnet
with custom port prefix and custom cosmos folder
crun install lava_testnet -e "custom_port_prefix=137;cosmos_folder=.lavatestnet"
This command will install lava_testnet with custom port prefix 137 and cosmos HOME folder .lavatestnet
RPC port will be 13757, P2P port will be 13756, GRPC port will be 13790, REST port will be 13717; instead of default 26657, 26656, 9090, 1317
