# Utopia Backend
To run the backend you can simply execute
`docker-compose up`
## Pull Data from Docker to Harddrive
In order to pull data from your locally running backend (see [docker-compose](../app/docker-compose.yml)) to your local harddrive, you can run the following command
```
npx directus-sync pull \

## How to apply a database dump to the docker
Assuming you run docker-compose with the default postgress credentials and have the dump in cwd as ./dump.sql, execute:
Find current schema name:
```
echo "SELECT CURRENT_SCHEMA, CURRENT_SCHEMA();" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
> current_schema | current_schema
> ----------------+----------------
> public | public
> (1 row)
Drop schemata (loses all data):
```
echo "DROP SCHEMA public CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
echo "DROP SCHEMA tiger CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
echo "DROP SCHEMA tiger_data CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
echo "DROP SCHEMA topology CASCADE;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
> drop cascades to table ...
> ...
> DROP SCHEMA
Create the public schema again:
```
echo "CREATE SCHEMA public;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
Verify schemata:
```
echo "select schema_name from information_schema.schemata;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus"
```
Verify database is empty:
```
echo "\dt" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus directus"
```
> Did not find any relations.
Create admin role & grant it:
```
echo "CREATE ROLE admin;" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus directus"
```
Apply dump:
```
docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql -v ON_ERROR_STOP=1 --username directus directus" < ./dump.sql
```
> Bring time depending on the dump size.
Reassign ownership of tables:
```
echo "REASSIGN OWNED BY admin TO directus" | docker exec -i utopia-map-database-1 /bin/bash -c "PGPASSWORD=directus psql --username directus directus
```
> REASSIGN OWNED
