Cosmopark

This page contains information about building and running Neutron node interconnected with a Gaia node by a Hermes IBC Relayer and a Neutron ICQ Relayer. This is a more advanced section than the basic sole Neutron node flow which is based on the Neutron's integration tests setup.

Prerequisites​

Build and run​

1. Make sure you have the required golang version:​

go version

The output should comply with the golang version mentioned in the Prerequisites section.

2. Clone necessary repositories​

You'll have to clone several repositories into a single parent folder. Choose a parent directory and make clonings from it. This is crucial to have all the repositories cloned and stored in the same parent folder.

Clone Neutron repositories​

git clone -b v3.0.2 https://github.com/neutron-org/neutron.git
git clone https://github.com/neutron-org/neutron-integration-tests.git
git clone -b v0.2.0 https://github.com/neutron-org/neutron-query-relayer.git

Clone and prepare Gaia​

We use the Gaia network as a target network for interchain operations. We use v15.0.0 for the tests.

git clone https://github.com/cosmos/gaia.git
cd gaia
git checkout v15.0.0

3. Build images​

The commands from this section are available from the setup folder in the neutron-integration-tests project.

If it's the first time you're here, run

make build-all

If you have the images built and you want to rebuild one of them, the following commands which build each component separately are also available:

make build-gaia
make build-neutron
make build-hermes
make build-relayer

4. Download Neutron DAO contracts​

Neutron has Neutron DAO contracts in genesis, so before running you need to download the latest version of contracts:

npx @neutron-org/get-artifacts neutron-dao -b main -d contracts

5. Run Cosmopark​

The commands from this section are available from the setup folder in the neutron-integration-tests project.

make start-cosmopark

A Neutron node, a Gaia node, a Hermes instance and an ICQ Relayer instance are now running in the background. To see the apps logs, run:

docker ps

And use the container ID you want to observe logs of:

docker logs -f <contained-id>

Cumulative logs are available via running

docker-compose logs -f

To stop cosmopark, run

make stop-cosmopark

6. Usage​

Neutron node​

The Neutron node usage guidelines (exposed ports, CLI, prepared accounts) for Cosmopark are the same as for the sole run. Please refer to the corresponding section to see more details on it.

Hermes​

For more information about Hermes, refer to the dedicated section and its configuration folder in the neutron-integraton-tests repo.

ICQ Relayer​

For more information about ICQ Relayer, refer to the dedicated section and its configuration via docker-compose file in the integration-tests repo.

Gaia​

The Gaia node running in the Cosmopark is configured via docker-compose file.
