Volumener er ikke tilgængelige på byggetidspunktet. Du kan oprette /var/lib/postgresql/data i dit script, men det vil blive overskrevet af VOLUME /var/lib/postgresql/data fra postgres:9.6 billede.
I dit tilfælde:brug blot følgende docker-fil:
FROM postgres:9.6
COPY ./create_fixtures.sql /docker-entrypoint-initdb.d/create_fixtures.sql
De udføres automatisk, når containeren starter. Her er et eksempel:
$ docker run -d --name mydb -p 33306:3306 yourtag
$ docker exec -ti mydb psql -U postgres
postgres=# \l

Forældet svar:
Dit script burde virke på en container undtagen i fixturen skal du udføre psql sådan her:
su postgres -c "psql -f create_fixtures.sql"
su --login postgres virker ikke, fordi postgres ikke kan åbne en bash eller shell. Du kan prøve rundt med docker run --rm -ti postgres:9.6 bash .
Beklager, jeg er nødt til at fortælle dig, at der er endnu en fejl i dit sql-script:GRANT ALL PRIVILEGES ON DATABASE mydatabase TO webuser - søgeordet DATABASE er nødvendigt her.
Her er en komplet log, hvordan jeg testede og kan bekræfte, at dette virker:
docker run --rm -ti postgres:9.6 bash
[email protected]:/# cat > test.sql <<EOF
> CREATE DATABASE mydatabase WITH ENCODING 'UTF8';
> CREATE USER webuser ENCRYPTED PASSWORD 'asdf123' NOSUPERUSER NOCREATEDB NOCREATEROLE;
> GRANT ALL PRIVILEGES ON DATABASE mydatabase TO webuser;
> EOF

The files belonging to this database system will be owned by user "postgres".
This user must also own the server process.
The database cluster will be initialized with locale "en_US.utf8".
The default database encoding has accordingly been set to "UTF8".
The default text search configuration will be set to "english".
Data page checksums are disabled.
