Hyperledger Sawtooth’s Application Development Practices

Certain practices can help developer create application which are one click deployable on Zeeve. They are:-

  • For packaging your product to be automated by Zeeve, you will need to dockerize you project’s services by creating Dockerfiles for them.

  • Create a docker-compose-build.yaml file creating images of all services that your application requires. This will help Zeeve to create relevant images and push it to the container-registry and later use it.

  • Make sure all the config that your application needs are pre-created in the Docker image itself.

  • Create a docker-compose-zeeve.yaml file and keep it at your root project folder. The file shall have references to the image names mentioned in the docker-compose-build.yaml. There is no need to mention any built contexts for images here, image name shall do.

  • All ports utlized by sawtooth services are curently set to default, so make sure you applications are configured to use default host machine’s ports.

  • Create an .env file at root of your project and mention you domain-prefix and port-number on host machine to expose. For example:-

    EXT_EXPOSED_SERVICES=("balancetranfer:3500" "another_service:3400")

    This will create a domain like balancetransfer.xxxxxx.zeeve.net & another_service.xxxxxx.zeeve.net which will map to 3500 & 3400 ports respectively and allow SSL connections.

For example of a sawtooth application please take a look at the demo supplychain application: Sawtooth Asset Tracking.
