--config- path to config file, in the config postgres is choosen, so it must be running--keypair_name- path to private and public keys of a the node-genesis_block- path to genesis block (first block of network)-reuse_state- not create network from beginning but use existing-overwrite_ledger -drop_state- DANGEROUS - it will erase the network (both database and files)
To run irohad with configuration arguments as above You need first to change something in config file or change config + have working postgres DB.
A) Using Iroha with postgres db:
I suggest to use docker instance. To create instance with user&&password compatible with sample config you need command (it needs to be run in host):
docker run --name postgres_tmp \
-e POSTGRES_USER=postgres \
-e POSTGRES_PASSWORD=mysecretpassword \
--network=host \
-d postgres \
-c 'max_prepared_transactions=100' \
-c 'port=5432'
Then you can just run irohad command.
B) Using Iroha with RocksDB:
Instead of postgres you can use RocksDB. In example directory there is sample config, which is using RocksDB, but path to database must be changed, e.g.:
sed -i 's_/path/to/wsv/folder_/home/rocksdb_g' example/config.sample
The next step is to use that config when running irohad:
./build/bin/irohad \
--config $PWD/example/config.sample \
--keypair_name $PWD/example/node0 \
-genesis_block $PWD/example/genesis.block \
-reuse_state
