Question

我正在尝试使用以下Dockerfile在Docker容器中创建一个postgres实例。

FROM postgres

ENV POSTGRES_DB dspace
ENV POSTGRES_USER dspace
ENV POSTGRES_PASSWORD dspace

COPY init.sql /docker-entrypoint-initdb.d/

这是我的init.sql

create extension pgcrpyto

我正在使用Codenvy服务来运行此容器。初始化时，我看到以下错误。

[STDOUT] server started

注意，我的解决方案基于以下帖子。 How to create postgres extension inside the container?

以下回购邮件解决了我的问题。看来我需要提供一个shell脚本来执行SQL。
