Docker Compose Testnet for Logos Blockchain
The Logos blockchain Docker Compose Testnet contains four distinct service types:
- Logos Blockchain Node Services: Multiple dynamically spawned Logos blockchain nodes that synchronizes their configuration via cfgsync utility.
Building
Upon making modifications to the codebase or the Dockerfile, the Logos blockchain images must be rebuilt:
docker compose build
Configuring
Configuration of the Docker testnet is accomplished using the .env file. An example configuration can be found in .env.example.
To adjust the count of Logos blockchain nodes, modify the variable:
DOCKER_COMPOSE_LIBP2P_REPLICAS=100
Running
Initiate the testnet by executing the following command:
docker compose up
This command will merge all output logs and display them in Stdout. For a more refined output, it's recommended to first run:
docker compose up -d
Followed by:
docker compose logs -f logos-blockchain-node
Using testnet
Bootstrap node is accessible from the host via 3000 and 18080 ports. To expose other Logos blockchain nodes, please update logos-blockchain-node service in the compose.yml file with this configuration:
logos-blockchain-node-0:
ports:
- "3001-3010:3000" # Use range depending on the number of Logos blockchain node replicas.
- "18081-18190:18080"
After running docker compose up, the randomly assigned ports can be viewed with ps command:
docker compose ps
