The majority of LocalTerra is implemented through a
docker-compose.yml file, making it easily customizable. You can use LocalTerra as a starting point for setting up your own local Terra testnet with Docker containers.
Out of the box, LocalTerra comes with several preconfigured settings such as:
Ports defined for RPC (26657), LCD (1317) and FCD (3060).

Speed up block time#
LocalTerra is often used alongside a script written with the Terra.js or Terra.py as a convenient way to do integration tests. You can greatly improve the experience by speeding up the block time.
To increase block time, edit the
[consensus] parameters in the
config/config.toml file, and specify your own values.
The following example configures all timeouts to
##### consensus configuration options ##### [consensus] wal_file = "data/cs.wal/wal" - timeout_propose = "3s" - timeout_propose_delta = "500ms" - timeout_prevote = "1s" - timeout_prevote_delta = "500ms" - timeout_precommit_delta = "500ms" - timeout_commit = "5s" + timeout_propose = "200ms" + timeout_propose_delta = "200ms" + timeout_prevote = "200ms" + timeout_prevote_delta = "200ms" + timeout_precommit_delta = "200ms" + timeout_commit = "200ms"
Additionally, you can use the following single line to configure timeouts:
sed -E -i '/timeout_(propose|prevote|precommit|commit)/s/[0-9]+m?s/200ms/' config/config.toml
You can change the
genesis.json file by altering
config/genesis.json. To load your changes, restart your LocalTerra.
