A single postgres database instance serves all nodes in an environment (eg. int or prod).
Each node and the database itself are configured with an environment file found in the environments directory. See: config
This project uses the Entity Framework (EF) as an ORM layer to help manage access to the database. In addition, EF also manages database migrations (where the model has changed).
On each launch of the application, the engine node will run all new migrations against the database before it reports itself healthy - and so all nodes benefit from an updated database.
Some entity framework commands to help you out are included below...
First, install the Entity Framework tool:
dotnet tool install --global dotnet-efUse this invocation to create a new migration:
dotnet ef migrations add MyFancyNewMigration --project ConsensusChessShared/ConsensusChessShared.csproj
