本文將指導(dǎo)讀者如何使用Docker搭建DNSmasq服務(wù),通過簡單的步驟和詳細(xì)的說明,幫助讀者快速在Docker環(huán)境中部署DNSmasq,具有一定的參考價(jià)值,感興趣的可以了解一下

Dockerfile 編寫

mkdir -p /data/docker/dns && cd /data/docker/dns && vim Dockerfile

FROM centos:centos7.9.2009 as builder

ENV GOROOT=/usr/local/go
ENV GOBIN=/usr/local/go/bin
ENV GOPATH=/usr/local/go/gopath
ENV GOPROXY=https://goproxy.cn,https://goproxy.io,direct
ENV PATH=$PATH:$GOBIN:$GOPATH/bin

WORKDIR /opt

RUN  yum -y update && yum -y install wget git \
&& wget --progress=bar:force https://studygolang.com/dl/golang/go1.19.5.linux-amd64.tar.gz \
&& tar -zxvf go1.19.5.linux-amd64.tar.gz -C /usr/local \
&& rm -f go1.19.5.linux-amd64.tar.gz \
&& git clone https://github.com/jpillora/webproc.git \
&& cd webproc \
&& go build -o webproc -v .

ENTRYPOINT ["/docker-entrypoint.sh"]

docker-entrypoint.sh 編寫

vim docker-entrypoint.sh

#!/bin/bash
systemctl start dnsmasq
webproc -c /etc/dnsmasq.conf -c /etc/hosts -- dnsmasq --no-daemon

編譯鏡像

vim build.sh

#!/bin/bash
docker build -t dnsmasq:latest .

編譯

sh build.sh

docker-compose.yml 編寫

vim docker-compose.yml

version: '3'

networks:
  app-tier:
    driver: bridge

services:
  etcd:
    image: 'dnsmasq:latest'
    container_name: "dns"
    restart: always
    ports:
      - 8080:8080

掛載路徑創(chuàng)建

創(chuàng)建掛載

mkdir -p /data/docker_volumes/dns/logs && touch /data/docker_volumes/dns/logs/dnsmasq.log

創(chuàng)建 dnsmasq.conf

vim /data/docker_volumes/dns/dnsmasq.conf
尾部寫入:

# Include all files in /etc/dnsmasq.d except RPM backup files
conf-dir=/etc/dnsmasq.d,.rpmnew,.rpmsave,.rpmorig

# dns log
log-facility=/va/log/dnsmasq.log
