我正在尝试创建一个 PostgreSQL 11.5 docker 容器。在此过程中，我想运行一个 SQL 脚本来创建必要的用户、表等。但是，每当容器启动时，我都会看到以下错误：
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.

Success. You can now start the database server using:
pg_ctl -D /var/lib/postgresql/data -l logfile start
WARNING: enabling "trust" authentication for local connections
You can change this by editing pg_hba.conf or using the option -A, or
--auth-local and --auth-host, the next time you run initdb.
****************************************************
WARNING: No password has been set for the database.
This will allow anyone with access to the
Postgres port to access your database. In
Docker's default configuration, this is
effectively any other container on the same
system.
Use "-e POSTGRES_PASSWORD=password" to set
it in "docker run".

/usr/local/bin/docker-entrypoint.sh: running /docker-entrypoint-initdb.d/init.sql
/docker-entrypoint-initdb.d/init.sql: Permission denied
My Dockerfile看起来像这样：
FROM postgres:11.5
ADD ./scripts/init.sql /docker-entrypoint-initdb.d/
ENTRYPOINT ["docker-entrypoint.sh"]
EXPOSE 5432
CMD ["postgres"]
And, my init.sql文件看起来像这样：
CREATE USER mydb WITH PASSWORD 'password';
CREATE DATABASE mydb;
GRANT ALL PRIVILEGES ON DATABASE mydb TO mydb;
你会注意到他们都没有做任何非常复杂的事情。然而，我仍然得到permission denied错误。我已连接到正在运行的容器并确认 init.sql 文件位于文件系统上。知道我在这里可能做错了什么吗？
那么从此Dockerfile我假设用户在 postgres 中。
尝试使用这个 Dockerfile
FROM postgres:11.5
USER postgres
RUN whoami
ADD ./scripts/init.sql /docker-entrypoint-initdb.d/
ENTRYPOINT ["docker-entrypoint.sh"]
EXPOSE 5432
CMD ["postgres"]
update:
似乎该文件不属于 Postgres 用户所有。
尝试设置权限
ADD ./scripts/init.sql /docker-entrypoint-initdb.d/
RUN chown postgres:postgres /docker-entrypoint-initdb.d/init.sql
