### How to create default database and user on starting
Sometimes you may want to create default user and database on image starting. You can do it using environment variables `CLICKHOUSE_DEFAULT_DB`, `CLICKHOUSE_DEFAULT_USER` and `CLICKHOUSE_DEFAULT_PASSWORD`:
```
$ docker run --rm -e CLICKHOUSE_DEFAULT_DB=my_database -e CLICKHOUSE_DEFAULT_USER=username -e CLICKHOUSE_DEFAULT_PASSWORD=password -p 9000:9000/tcp yandex/clickhouse-server
```
## How to extend this image ## How to extend this image
If you would like to do additional initialization in an image derived from this one, add one or more `*.sql`, `*.sql.gz`, or `*.sh` scripts under `/docker-entrypoint-initdb.d`. After the entrypoint calls `initdb` it will run any `*.sql` files, run any executable `*.sh` scripts, and source any non-executable `*.sh` scripts found in that directory to do further initialization before starting the service.
