Detailed Introduction to Installing Quagga in Docker

The virtual router project in openstack consumes too many resources, it is necessary to migrate the virtual router to Docker, and it is considered that several problems need to be solved first.

　　　　 1. How to integrate docker into openstack, this issue has been given three solutions by the openstack official, based on nova, heat, and a separate container project

　　　　 2. After integrating docker, the container management and orchestration decides to adopt K8S

　　　　 3Is it possible to install quagga in docker, package it into a quagga image for subsequent development and automatic configuration programs?

Today, I tried to install quagga in docker and automatically start the processes of zebra, ripd, ospfd, and bgpdz. There are many online resources about docker installation and usage, please refer to them by yourself.

The image construction is automatically built according to the Dockerfile file, and then the container is run based on the built image.

Dockerfile

 FROM lijianfeng/ubuntu:v1.0
 MAINTAINER lijianfeng
 RUN apt-get install -y quagga
 RUN apt-get install -y telnet
 ADD zebra.conf /etc/quagga/zebra.conf
 ADD ospfd.conf /etc/quagga/ospfd.conf
 ADD ripd.conf /etc/quagga/ripd.conf
 ADD bgpd.conf /etc/quagga/bgpd.conf
 ADD init_conf.sh /etc/quagga/init_conf.sh
 CMD sh /etc/quagga/init_conf.sh ; /bin/bash

Note: lijianfeng/ubuntu:v1.0 base image is self-made, just like the official Ubuntu:14.04Common software packages are installed.

Create zebra.conf, ospfd.conf, ripd.conf, bgpd.conf in the same directory as Dockerfile, content is

hostname router

password zebra

enable password zebra　 //Only zebra.conf has it, others do not

log stdout

Create init_conf.sh in the same directory as Dockerfile, content is

 #!/bin/bash
 sed -ri "s/hostname .+/hostname $HOSTNAME/" /etc/quagga/zebra.conf
 sed -ri "s/hostname .+/hostname $HOSTNAME/" /etc/quagga/ripd.conf
 sed -ri "s/hostname .+/hostname $HOSTNAME/" /etc/quagga/ospfd.conf
 sed -ri "s/hostname .+/hostname $HOSTNAME/" /etc/quagga/bgpd.conf
 chown -R quagga.quagga /etc/quagga
 /usr/lib/quagga/zebra -d
 /usr/lib/quagga/ripd -d
 /usr/lib/quagga/ospfd -d
 /usr/lib/quagga/bgpd -d

Image creation:

docker build -t lijianfeng/quagga .

Because the image is built in the same directory, the last one is . , otherwise an absolute path is required

Build completed, check through docker images, and lijianfeng will appear/quagga image

Container running, using pseudo-terminal interactive mode here

docker run -it --name router --hostname router --privileged=true lijianfeng/quagga

After the command is executed, it will enter the docker operation space, which can be accessed by telnet localhost <port> to enter the corresponding daemon process.
