基于官方postgres docker镜像制做本身的镜像

2021年09月16日 阅读数:2
这篇文章主要向大家介绍基于官方postgres docker镜像制做本身的镜像,主要内容包括基础应用、实用技巧、原理机制等方面,希望对大家有所帮助。

一、Dockerfilelinux

FROM library/postgres
MAINTAINER wenbin.ouyang

#初始化PostgreSQL
ENV POSTGRES_USER root
ENV POSTGRES_PASSWORD root
ENV POSTGRES_DB noah
ADD ./noah_pgsql_init.sql /docker-entrypoint-initdb.d/

#容器运行时监听的端口
EXPOSE 5432

  

二、构建镜像sql

docker build -f ./Dockerfile -t oy/pgsql:1.0.0 .

 

  docker images: 查看镜像docker

 

三、建立容器bootstrap

  容器中postgresql的数据存放位置:/var/lib/postgresql/data,经过容器添加卷指令将容器数据存放位置映射到宿主机:-v /var/lib/postgresql/oy_PostgreSQL_1.0.0_data:/var/lib/postgresql/databash

docker run -it -p 9001:5432 -v /var/lib/postgresql/oy_PostgreSQL_1.0.0_data:/var/lib/postgresql/data oy/pgsql:1.0.0

  docker ps: 查看运行的容器socket

  docker exec -it 容器id /bin/bash:进入到容器post

 

  建立容器时的打印:ui

root@alihkdev13:/usr/local/resource# docker run -it -p 9001:5432 -v /var/lib/postgresql/oy_PostgreSQL_1.0.0_data:/var/lib/postgresql/data oy/pgsql:1.0.0
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.

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.

Success. You can now start the database server using:

    pg_ctl -D /var/lib/postgresql/data -l logfile start
