Dockery(多颗粒)

Dockery(多颗粒) provides examples of building docker images mainly in two areas:

• Examples for building dedicated/edged images that the community hasn't supported yet, for example, ruby 3 + rails 7 + postgres 14.
• Examples for building image in China due to network lags, for example, nextjs base

Naming this project with Dockerfy because it sounds cute, and its phonetic translation in Chinese 多颗粒 directly implies that this project is the aggregation of a variety of practices.

Hope Dockerfy improve your dev team's productivity, any pull request is welcome for building image not included.

Get started

Scripts here are written in google zx which should be installed before trying your own.

Images supported

Image	OS	Repo	Tags
next.js	alpine	ruilisi/nextjs-base	12.1.0
ruby 3 + postgres 14	debian	ruilisi/ruby	3.1.2,3.2
golang	*	ruilisi/golang	*
golang-ci	*	ruilisi/golang-ci	*

alphine

~$ cd alpine; ./build.mjs --tag TAG

Simply changes mirror of offical image to mirrors.ustc.edu.cn.

Detailed explanation for images

Nextjs

Building docker image of nextjs based project with alpine base in China is complicated, cause the following issues need to be resolved:

• Globally install module sharp.
• Before installing module sharp, you have to install libraries: vips-dev fftw-dev, otherwise it won't compile.
• The above libraries can only be installed through repository https://dl-3.alpinelinux.org/alpine/edge/testing/ currently, and proxy is needed when accessing this repo in some areas.
• Since proxy is only required during some of the steps, an agile way of doing this is needed (providing the proxy address in host machine and let the container aware of it).

yarn configs included to speed up yarn install in China:

Name	URL
registry	https://registry.npm.taobao.org
sentrycli_cdnurl	https://cdn.npm.taobao.org/dist/sentry-cli

Other tools and configs are also provided in order to make later image building faster and make image size smaller:

• Use an alpine mirror inside China.
• Config taobao npm registry.

Use it in your Dockerfile:

FROM ccr.ccs.tencentyun.com/ruilisi-pub/nextjs-base:VERSION
...
COPY next.config.js ./
COPY public ./public
COPY package.json ./package.json
COPY .next/standalone ./
COPY .next/static ./.next/static
COPY .env.production ./.env.production

ruby 3 + postgres 14

# building ruby image as an example
~$ cd ruby 
~$ ./build.mjs -h
Usage:
./build.mjs [--version [3.1.2|3.2|2.7|...]] [-h]
~$ ./build.mjs --version 3.1.2

Image for ruby 3 and image for postgres 14 are all available, however, combining both is tedious.

This image simply gives you newest experience with ruby & postgres without pain!

Golang

~$ cd golang; ./build.mjs --tag TAG

Simply changes mirror of offical image to mirrors.ustc.edu.cn and adds goproxy.

Golang CI

~$ cd golang; ./build.mjs --tag TAG --ci

This image includes neccessary tools or packages useful for CI of golang:

• revive to lint and check golang code.
• ruilisi/govet as an example for using go vet.
• gotestsum to print formatted test output.
• make, gcc to ensure commands in makefile can be executed

A dedicated image golang-ci is thus built and any recommendation is welcome on how to make it more general.
