How to Deploy a Subnet on a Local Network

This how-to guide focuses on taking an already created Subnet configuration and deploying it to a local Avalanche network.

Prerequisites

Deploying Subnets Locally

In the following commands, make sure to substitute the name of your Subnet configuration for <subnetName>.

To deploy your Subnet, run

avalanche subnet deploy <subnetName>

and select Local Network to deploy on. Alternatively, you can bypass this prompt by providing the --local flag. For example:

avalanche subnet deploy <subnetName> --local

The command may take a couple minutes to run.

Results

If all works as expected, the command output should look something like this:

> avalanche subnet deploy mySubnet

You can use the deployment details to connect to and interact with your Subnet.

To manage the newly deployed local Avalanche network, see the avalanche network command tree.

Deploying Multiple Subnets

You may deploy multiple Subnets concurrently, but you can't deploy the same Subnet multiple times without resetting all deployed Subnet state.

Redeploying the Subnet

To redeploy the Subnet, you first need to wipe the Subnet state. This permanently deletes all data from all locally deployed Subnets. To do so, run

avalanche network clean

You are now free to redeploy your Subnet with

avalanche subnet deploy <subnetName> --local
