Iroha 2

Appearance

Quick Start with Docker ​

  1. Install the prerequisites:

  2. Install Iroha from GitHub.

  3. Run docker compose to bring up a network of 4 containerised peers:

    bash
    $ docker compose up

    Depending on your set-up, this might either pull the image off of DockerHub, or build the container locally. After this process is complete, you'll be greeted with,

  4. Follow the Bash tutorial to check out Iroha's capabilities.

  5. When you're done with the test network, just hit Control + C to stop the containers (⌃ + C on Mac).

Docker Options ​

You might also be interested in other options for local compilation:

  • For testing Iroha code quickly, you can use docker-compose-single.yml, which starts a container with a single peer.
  • For testing Iroha code in normal conditions, you can use docker-compose-local.yml, which starts 4 connected containers with peers.

INFO

Please note that there is ongoing work to make our configurations for Docker even more customizable with the help of Swarm.
