If you’re looking for a quick demo of the functionality, the simplest thing to do after running the Docker container's default command is to launch the substrate-front-end-template UI.
git clone https://github.com/substrate-developer-hub/substrate-front-end-template cd substrate-front-end-template yarn install yarn start
Once the UI opens in your browser, scroll down to the Pallet Interactor section at the bottom.
Keep the default "Extrinsic" active, then select
templateModulefrom the first dropdown.
Then, select the callable you want from the list of callables that become available:
An additional text field or fields will appear below the last select box. Type the arguments in and then click Signed.
Watch your node logs and also the extrinsic events to the right for output and information.
This demo is based on our included
templateModule pallet - mostly meant as a showcase
of the embedded [Rust IPFS] node. In the next section we will walk you through this pallet,
which will be instructive as a reference implementation.
