老师你好, 我是使用的coredns是通过docker安装的, 请问下 coredns_custom_build 考虑支持构建docker镜像吗?

在 coredns_custom_build 中, 没搜索到docker关键字, 于是过来问问

下边是我的 docker-compose.yaml 文件, 使用的是官方的镜像 coredns/coredns

 services:
   coredns:
     container_name: coredns
     restart: always
     volumes:
       - ./data:/etc/coredns
     ports:
       - 53:53/udp
     image: coredns/coredns
     command: -conf /etc/coredns/Corefile
     environment:
       - TZ=Asia/Shanghai

最近我想让coredns支持ads功能, 在这里找到了
由于其没有构建docker镜像, 我尝试自己构建, 下边是参考脚本

#!/bin/bash

 # Step 1: Fetch the webpage content
 URL="https://coredns.minidump.info/dl/coredns-linux-amd64.zip"
 WEBPAGE=$(curl -s $URL)

 # Step 2: Parse the download URL from the webpage content
 # Assuming the download link is directly provided in the URL
 DOWNLOAD_URL=$(echo "$WEBPAGE" | grep -oP '(?<=href=")[^"]*coredns-linux-amd64.zip')

 # If the DOWNLOAD_URL is relative, prepend the base URL
 if [[ $DOWNLOAD_URL != http* ]]; then
     BASE_URL=$(echo $URL | grep -oP 'https?://[^/]+')
     DOWNLOAD_URL="$BASE_URL/$DOWNLOAD_URL"
 fi

 # Step 3: Download the file using wget or curl
 wget -O coredns-linux-amd64.zip "$DOWNLOAD_URL"
 # or
 # curl -o coredns-linux-amd64.zip "$DOWNLOAD_URL"

 echo "Downloaded to coredns-linux-amd64.zip"

 unzip -d . coredns-linux-amd64.zip
 cd coredns-linux-amd64

 curl -ssLO https://github.com/coredns/coredns/raw/master/Dockerfile

 docker buildx create --use --name coredns-env-builder
 docker buildx build --platform linux/amd64 -t coredns-custom .

因网络环境问题, 后面把脚本移植成workflow放在Actions中执行构建

name: Build and Publish

on:
  workflow_dispatch:

jobs:
  build-and-publish:
    runs-on: ubuntu-latest

    - name: Get CoreDNS download URL
      id: get-url
      run: |
        URL="https://coredns.minidump.info/dl/coredns-linux-amd64.zip"
        WEBPAGE=$(curl -s $URL)
        DOWNLOAD_URL=$(echo "$WEBPAGE" | grep -oP '(?<=href=")[^"]*coredns-linux-amd64.zip')
        echo "::set-output name=download_url::$DOWNLOAD_URL"

    - name: Download CoreDNS binary
      run: |
        curl -s -L -o coredns-linux-amd64.zip "${{ steps.get-url.outputs.download_url }}"

    - name: Unzip CoreDNS binary
      run: |
        unzip -d . coredns-linux-amd64.zip

    - name: Download Dockerfile
      run: |
        curl -s -L -o coredns-linux-amd64/Dockerfile https://github.com/coredns/coredns/raw/master/Dockerfile

    - name: Set up Docker Buildx
      uses: docker/setup-buildx-action@v2
        
    - name: Log in to Docker Hub
      uses: docker/login-action@v2
      with:
        username: ${{ secrets.DOCKER_USERNAME }}
        password: ${{ secrets.DOCKER_PASSWORD }}

    - name: Build and push Docker image
      run: |
        cd coredns-linux-amd64
        docker buildx build --platform linux/amd64 -t ${{ secrets.DOCKER_USERNAME }}/coredns-custom:latest --push .

最终得到 coredns-custom 镜像, 一切正常

希望老师能支持构建Docker镜像,感谢
