Docker for Mac 所建立的dnsmasq容器連不上/不運作的問題
在使用docker for mac構建了一個dnsmasq的Container, 但是發現53端口似乎無法連接, 使用dig各種超時
這是dockerfile
FROM centos:6.8
RUN yum update -y && yum install -y dnsmasq
RUN echo "listen-address=0.0.0.0" > /etc/dnsmasq.conf
RUN echo "conf-dir=/etc/dnsmasq.d" >> /etc/dnsmasq.conf
RUN echo "user=root" >> /etc/dnsmasq.conf
RUN echo "server=/a/127.0.0.1" >> /etc/dnsmasq.conf
#a供测试用
#RUN echo 'resolv-file=/etc/resolv.dnsmasq.conf' >> /etc/dnsmasq.conf
#RUN echo "nameserver 127.0.0.11" > /etc/resolv.dnsmasq.conf
#上一行出现了127.0.0.11并不是写错, 而是发现docker for mac的container的/etc/resolv.conf里面确实出现了127.0.0.11, 并且这个上面是可以解析域名的, 所以才试图这么尝试过这个配置
RUN yum install nc -y
RUN yum clean all
EXPOSE 53
EXPOSE 53/udp
#CMD ["nc", "-l", "53"] #tcp调试
#CMD ["nc", "-l", "-u", "53"] #udp调试
CMD ["/usr/sbin/dnsmasq", "-d"]這是docker-compose
version: '2'
services:
dns:
build: ../../images/dnsmasq
container_name: dns
restart: always
#env_file: ./config/.env
# volumes:
# - /etc/hosts:/etc/hosts
# dns:
# - 127.0.0.1
ports:
- "53:53"
- "53:53/udp"各種連接埠映射應該是沒有問題的, 宿主機上運行和訪問:
容器內運作和存取:
