微天气 Github Action镜像自动构建与推送

前言

这里暂不作过多的操作，还是保持与此前一致。即通过Github Action完成Docker Image的build与push，目标仓库为阿里云容器镜像服务实例（个人版）registry.cn-hangzhou.aliyuncs.com

那么一共分为三个部分：

Dockerfile编写
阿里云容器镜像服务配置
Github Action

Dockerfile编写

jdk17
gradle

FROM gradle:jdk17-alpine AS build

# 设置语言，支持中文
ENV LANG C.UTF-8

COPY --chown=gradle:gradle . /opt/gradle/src
WORKDIR /opt/gradle/src
RUN gradle clean build -x test --no-daemon

FROM eclipse-temurin:17-jdk-jammy

COPY --from=build /opt/gradle/src/build/libs/*.jar /usr/app/

WORKDIR /usr/app/

RUN sh -c 'touch micro-weather-backend-1.0.0-RELEASE.jar'

ENTRYPOINT ["java", "-jar", "micro-weather-backend-1.0.0-RELEASE.jar"]

Github Action

先在阿里云镜像服务中创建命名空间
创建仓库（可选，因为可以自动创建）

编写Github Action脚本

micro-weather-github-action-01

name: Micro Weather Service Image Build And Push CI

on:
push:
    branches:
    - 'main'
jobs:
docker:
    runs-on: ubuntu-latest
    steps:
    - name: Checkout
        uses: actions/checkout@v2

    # setup-qemu 如果您想使用 QEMU 添加仿真支持以便能够针对更多平台进行构建，则 action 会很有用
    - name: Set up QEMU
        uses: docker/setup-qemu-action@v1

    # setup-buildx-action 将默认使用docker-container 构建器驱动程序创建和引导构建器。非必需
    - name: Set up Docker Buildx
        uses: docker/setup-buildx-action@v1

    - name: Login to Aliyun DockerHub

    - name: Build and push
        uses: docker/build-push-action@v2
        with:
        push: true
        tags: registry.cn-hangzhou.aliyuncs.com/fuyi-atlas/micro-weather:latest
