Run a localnet with Docker


This document provides instructions on how to run a localnet with multiple validator/non-validator nodes. This can be useful if you are developing applications to work on cheqd network, or in automated testing pipelines.

The techniques described here are used in CI/CD contexts, for example, in this repository itself in the test.yml Github workflow.



Our localnet setup instructions are designed to set up a local network with the following node types:

  • 3x validator nodes

  • 1x non-validator/observer node

  • 1x seed node

The definition for this network is described in a localnet Docker Compose file, which can be modified as required for your specific use case. Since it's not possible to cover all possible localnet setups, the following instructions describe the steps necessary to execute a setup similar to that using in our Github test workflow.

Generate localnet configuration (one-time)

Execute the bash script to generate validator keys and node configuration for the node types above.


You may modify the output if you want a different mix of node types.

Import the generated keys (one-time)

Import the keys generated using the bash script:


Bring up the localnet using Docker Compose

Modify the docker-compose.yml file if necessary, along with the per-container environment variables under the container-env folder.

docker compose --env-file build-latest.env up --detach --no-build

Interacting with localnet

The default Docker localnet will configure a running network with a pre-built image or custom image.


The five nodes and corresponding ports set up by the default Docker Compose setup will be:

  1. Validator nodes

    1. validator-0

      1. P2P: 26656

      2. RPC: 26657

    2. validator-1

      1. P2P: 26756

      2. RPC: 26757

    3. validator-2

      1. P2P: 26856

      2. RPC: 26857

    4. validator-3

      1. P2P: 26956

      2. RPC: 26957

  2. Seed node

    1. seed-0

      1. P2P: 27056

      2. RPC: 27057

  3. Observer node

    1. observer-0

      1. P2P: 27156

      2. RPC: 27157

You can tests connection to a node using browser: http://localhost:<rpc_port>. Example for the first node: http://localhost:26657.


Key and corresponding accounts will be placed in the network config folder by the script, which are used within the nodes configured above.

When connecting using CLI, provide the --home parameter to any CLI command to point to the specific home directory of the corresponding node: --home network-config/validator-x.
