docker run --rm -d -p 26257:26257 --name aca-local-crdb cockroachdb/cockroach:v23.1.11 start-single-node --insecure
docker exec aca-local-crdb cockroach sql --insecure -e 'CREATE DATABASE crdbdemo'

docker run -e 'POSTGRES_PASSWORD=sa_password!123456' -p 5432:5432 --name aca-local-psql -d postgres:14.5

• Cockroach:
  • atlas schema apply --auto-approve -u 'postgres://root@127.0.0.1:26257/crdbdemo?sslmode=disable' -f file://schema --schema public,Platform

Apply migrations (TVFs)

• Initialization
  • First run atlas migrate hash --dir file://migrations
• Postgres:
  • atlas migrate apply -u 'postgres://postgres:sa_password!123456@127.0.0.1:5432/crdbdemo?sslmode=disable' --dir file://migrations --allow-dirty
• Cockroach:
  • atlas migrate apply -u 'postgres://root@127.0.0.1:26257/crdbdemo?sslmode=disable' --dir file://migrations --allow-dirty

  • First run dotnet restore to restore the project
  • Then dotnet tool restore to install the cli tool

  • dotnet ef dbcontext scaffold "Host=127.0.0.1;Port=5432;Database=crdbdemo;Username=postgres;Password=sa_password!123456" Npgsql.EntityFrameworkCore.PostgreSQL --verbose --context EntityContext --context-dir Entities --output-dir Entities --data-annotations --force --no-onconfiguring --no-pluralize
• Cockroach:
  • dotnet ef dbcontext scaffold "Host=127.0.0.1;Port=26257;Database=crdbdemo;Username=root" Npgsql.EntityFrameworkCore.PostgreSQL --verbose --context EntityContext --context-dir Entities --output-dir Entities --data-annotations --force --no-onconfiguring --no-pluralize
