The [service](https://docs.drone.io/examples/service/postgres/) of drone.io is a way to include some dependent service into the pipeline.

**I would like to know if the services will be created for each build, so Is the service isolated for each build or shared?**

I already tried to find it via documentation of services but there is not this information there.

```
services:
  postgres:
    image: postgres
    environment:
      - POSTGRES_PASSWORD=pass
      - POSTGRES_USER=user
      - POSTGRES_DB=db

```

I expect that each build creates its own service to keep the things separated.

After I had talked to the core developers I discoreved the answer and now I am sharing here as well
