• Install dependencies using instructions from here

• Build Acala: `cargo build --release

• Run ./target/release/acala --chain=acala

Using Docker

• Image: acala/acala-node:latest or acala/acala-node:[version number]

• docker run acala/acala-node:latest --chain=acala

Common CLI

• CLI is mostly the same as any Substrate-based chain such as Kusama and Polkadot

• Because there are two node services are running, -- is used to split the CLI. Arguments before -- are passed to the parachain full-node service and arguments after -- is passed to the Relay Chain full-node service.

  • For example --chain=parachain.json --rpc-port=9944 -- --chain=relaychain.json --rpc-port=9945 means

    • The parachain service is using parachain.json as the chain spec and the web socket RPC port is 9944

    • The Relay Chain service is using relaychain.json as the chain spec and the web socket

      RPC port is 9945

• It is recommended to explicitly specify the ports for both services to avoid confusion

  • For example --listen-addr=/ip4/0.0.0.0/tcp/30333 --listen-addr=/ip4/0.0.0.0/tcp/30334/ws -- --listen-addr=/ip4/0.0.0.0/tcp/30335 --listen-addr=/ip4/0.0.0.0/tcp/30336/ws

• It is recommended to add --execution=wasm for parachain service to avoid syncing issues.

• It is recommended to add --relay-chain-rpc-url or --relay-chain-rpc-urls for parachain service to avoid fully sync with the relay chain to work, so in general, they will use fewer system resources.
