- You have to clone cardano-configurations somewhere and use an absolute path to it in your configuration
- You can set up a dev environment with cardano-node, ogmios, ogmios-datum-cache, kupo (optional) and ctl-server (optional) using the template below
- Use
nix developto spin up a shell, then usestart-node,start-ogmios,start-datum-cache,start-kupoorstart-ctl-serverto start the applications - Use
start-postgres(hacky implementation) to create a docker container with postgres (required by ogmios-datum-cache) Note: docker is not included in the flake
