Cleos |
cleos
is a command line tool that interfaces with the REST API exposed by nodeos
. Developers can also use cleos
to deploy and test EOSIO-Taurus smart contracts.
cleos
is distributed as part of the EOSIO-Taurus software suite. To install cleos
just visit the EOSIO-Taurus Software Installation section.
To use cleos
, you need the end point (IP address and port number) of a running nodeos
instance. Also, the nodeos
instance must be configured to load the eosio::chain_api_plugin
when launched. This allows nodeos
to respond to the RPC requests coming from cleos
.

cleos --help
