Running Avail Node

Manually

To manually run the Avail Node, you'll need to have the following dependencies installed:

• Rust
• Substrate dependencies

After ensuring you have the dependencies installed, you can run the Avail Node using the following command:

mkdir -p output
cargo run --locked --release -- --chain kate -d ./output

This command complies and runs the Avail Node connected to the Kate Network.

Running Dev Chain

A development chain is typically used for testing and development purposes.

cargo run --locked --release -- --chain dev

Docker

To run the Avail Node using Docker, follow these steps:

# Build the Docker image for the Avail Node:
docker build -t availnode -f ./dockerfiles/avail-node.Dockerfile .

# Create an output directory. Here the node's data will be stored.
mkdir output

# Run the Avail Node container:
docker run --rm -p 30333:30333 -p 9944:9944 -v ./output:/output availnode
# For SELinux
docker run --rm -p 30333:30333 -p 9944:9944 -v ./output:/output:z availnode
