运行postgres容器获得超级用户密码错误？

Question

DockerFile：

FROM library/postgres
COPY init.sql /docker-entrypoint-initdb.d/

init.sql：

CREATE TABLE incident_disposition (
incident_disposition_code VARCHAR,
incident_disposition_code_description VARCHAR
);

据我所知，从图书馆。..从docker hub中拉出postgres图像，副本将我的init.sql脚本推入入口点，所以不需要大的dockerfile，对吗？

 docker build -t my_postgres_image .

docker run --name testing my_postgres_image --publish 8000:8080 --detach  -e POSTGRES_PASSWORD=postgres -d postgres

日志中的错误

Error: Database is uninitialized and superuser password is not specified.
       You must specify POSTGRES_PASSWORD to a non-empty value for the
       superuser. For example, "-e POSTGRES_PASSWORD=password" on "docker run".

       You may also use "POSTGRES_HOST_AUTH_METHOD=trust" to allow all
       connections without a password. This is *not* recommended.

       See PostgreSQL documentation about "trust":
       https://www.postgresql.org/docs/current/auth-trust.html

从评论中尝试：

docker container logs testing
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

initdb: 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.

除评论外

由于最近的docker Image的更新，postgres images不允许在没有密码的情况下从任何地方连接到DB。所以您需要指定用户名/密码

docker run-P 8000:8080-e postgres_password=postgres--name testing-d my_postgres_image
