pgspider fetchq 扩展docker镜像

Posted 2020-12-13 rongfengliang-荣锋亮

fetchq 是一个队列系统，以下是一个pgspider 扩展的构建

pgspider base 镜像

添加了uuid 扩展

FROM debian:stretch-slim

RUN apt-get update && apt-get install -y build-essential git libossp-uuid-dev wget libreadline-dev  zlib1g-dev

WORKDIR /app

RUN set -eux; 

   if [ -f /etc/dpkg/dpkg.cfg.d/docker ]; then 

   # if this file exists, we‘re likely in "debian:xxx-slim", and locales are thus being excluded so we need to remove that exclusion (since we need locales)

   grep -q ‘/usr/share/locale‘ /etc/dpkg/dpkg.cfg.d/docker; 

   sed -ri ‘//usr/share/locale/d‘ /etc/dpkg/dpkg.cfg.d/docker; 

   ! grep -q ‘/usr/share/locale‘ /etc/dpkg/dpkg.cfg.d/docker;

RUN set -eux;

fetchq docker 镜像

EXPOSE 5432

CMD ["postgres"]

使用

• 启动

docker run -d -e POSTGRES_PASSWORD=dalong dalongrong/pgspider:fetchq

• 创建扩展

CREATE EXTENSION IF NOT EXISTS "fetchq";

CREATE EXTENSION IF NOT EXISTS "uuid-ossp";

说明

以上是一个简单的docker镜像，后边会详细说明下实现
