假设没有符合您需要的码头形象码头枢纽，你可以自己创造一个。
首先创建一个新的Dockerfile*
注这个PostgreSQL设置只用于开发目的。请参考PostgreSQL文档来微调这些设置，使其具有适当的安全性。
# # example Dockerfile for https://docs.docker.com/examples/postgresql_service/# FROM ubuntu # Add the PostgreSQL PGP key to verify their Debian packages.# It should be the same key as https://www.postgresql.org/media/keys/ACCC4CF8.asc RUN apt-key adv --keyserver hkp://p80.pool.sks-keyservers.net:80 --recv-keys B97B0AFCAA1A47F044F244A07FCC7D46ACCC4CF8 # Add PostgreSQL's repository. It contains the most recent stable release # of PostgreSQL, ``9.3``.RUN echo "deb http://apt.postgresql.org/pub/repos/apt/ precise-pgdg main" > /etc/apt/sources.list.d/pgdg.list # Install ``python-software-properties``, ``software-properties-common`` and PostgreSQL 9.3# There are some warnings (in red) that show up during the build. You can hide # them by prefixing each apt-get statement with DEBIAN_FRONTEND=noninteractive RUN apt-get update && apt-get install -y python-software-properties software-properties-common postgresql-9.3 postgresql-client-9.3 postgresql-contrib-9.3# Note: The official Debian and Ubuntu images automatically ``apt-get clean``# after each ``apt-get``# Run the rest of the commands as the ``postgres`` user created by the ``postgres-9.3`` package when it was ``apt-get installed``USER postgres # Create a PostgreSQL role named ``docker`` with ``docker`` as the password and # then create a database `docker` owned by the ``docker`` role.# Note: here we use ``&&\`` to run commands one after the other - the ``\``# allows the RUN command to span multiple lines.RUN /etc/init.d/postgresql start &&\ psql --command "CREATE USER docker WITH SUPERUSER PASSWORD 'docker';" &&\ createdb -O docker docker # Adjust PostgreSQL configuration so that remote connections to the # database are possible.RUN echo "host all all 0.0.0.0/0 md5" >> /etc/postgresql/9.3/main/pg_hba.conf # And add ``listen_addresses`` to ``/etc/postgresql/9.3/main/postgresql.conf``RUN echo "listen_addresses='*'" >> /etc/postgresql/9.3/main/postgresql.conf # Expose the PostgreSQL port EXPOSE 5432# Add VOLUMEs to allow backup of config, logs and databases VOLUME ["/etc/postgresql", "/var/log/postgresql", "/var/lib/postgresql"]# Set the default command to run when starting the container CMD ["/usr/lib/postgresql/9.3/bin/postgres", "-D", "/var/lib/postgresql/9.3/main", "-c", "config_file=/etc/postgresql/9.3/main/postgresql.conf"]
从Dockerfile构建一个图像，为它指定一个名称。
$ docker build -t eg_postgresql .
在前台%29中运行PostgreSQL服务器容器%28：
$ docker run --rm -P --name pg_test eg_postgresql
有两种连接PostgreSQL服务器的方法。我们可以用链接容器，或者我们可以从主机%28或网络%29访问它。
注*
--rm在容器成功退出时移除容器及其图像。
容器可以直接链接到另一个容器的港口-link remote_name:local_alias在客户的docker run这将设置一些环境变量，然后可用于连接：
$ docker run --rm -t -i --link pg_test:pg eg_postgresql bash postgres@7ef98b1b7243:/$ psql -h $PG_PORT_5432_TCP_ADDR -p $PG_PORT_5432_TCP_PORT -d docker -U docker --password
假设安装了PostgreSQLClient，也可以使用主机映射端口进行测试。你需要用docker ps要了解容器首先映射到哪个本地主机端口：
$ docker ps CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES 5e24362f27f6 eg_postgresql:latest /usr/lib/postgresql/ About an hour ago Up About an hour 0.0.0.0:49153->5432/tcp pg_test $ psql -h localhost -p 49153 -d docker -U docker --password
一旦您通过身份验证并拥有docker =#提示，您可以创建一个表并填充它。
psql (9.3.1)Type "help" for help.$ docker=# CREATE TABLE cities (docker(# name varchar(80),docker(# location pointdocker(# );CREATE TABLE
$ docker=# INSERT INTO cities VALUES ('San Francisco', '(-194.0, 53.0)');INSERT 0 1$ docker=# select * from cities;
name | location---------------+-----------
San Francisco | (-194,53)(1 row)可以使用定义的卷检查PostgreSQL日志文件，并备份配置和数据：
$ docker run --rm --volumes-from pg_test -t -i busybox sh/ # ls bin etc lib linuxrc mnt proc run sys usr dev home lib64 media opt root sbin tmp var/ # ls /etc/postgresql/9.3/main/environment pg_hba.conf postgresql.conf pg_ctl.conf pg_ident.conf start.conf/tmp # ls /var/log ldconfig postgresql
