SONiC vs testbed搭建

准备工作

  • 一台安装Ubuntu18.04的系统，内存建议不少于16G,需要支持kvm虚拟化
  • 安装ssh server
sudo apt update -y
sudo apt openssh-server -y
  • 设置sudo免密
sudo visudo
#最后一行加上自己的用户名
ljyfree ALL=(ALL:ALL) NOPASSWD: ALL
#退出
  • 安装必要的软件
sudo apt install python python-pip -y
sudo pip install j2cli==0.3.10
sudo apt install git vim -y
  • 安装虚拟化需要的软件
sudo apt-get install qemu-kvm qemu virt-manager virt-viewer -yljyfree@testbed:~$ kvm-ok 
INFO: /dev/kvm exists
KVM acceleration can be used
ljyfree@testbed:~$
  • GitHub上面拉代码慢，可以先用gitee克隆，然后直接从gitee上拉取
ljyfree@sonic-testbed:~$ git clone https://gitee.com/ljyfree/sonic-mgmt.git
Cloning into 'sonic-mgmt'...

ljyfree@sonic-testbed:~$
  • 安装docker
sudo apt-get install \ca-certificates \curl \gnupg \lsb-release -ysudo mkdir -p /etc/apt/keyrings
curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /etc/apt/keyrings/docker.gpgecho \"deb [arch=$(dpkg --print-architecture) signed-by=/etc/apt/keyrings/docker.gpg] https://download.docker.com/linux/ubuntu \$(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/nullsudo apt-get update -y
sudo apt-get install docker-ce docker-ce-cli containerd.io docker-compose-plugin -y
  • 将当前用户加到docker这个group中,然后退出后重新登录
ljyfree@testbed:~$ sudo groupadd docker
groupadd: group 'docker' already exists
ljyfree@testbed:~$ sudo usermod -aG docker $USER
ljyfree@testbed:~$ 
ljyfree@testbed:~$ 
ljyfree@testbed:~$ 
ljyfree@testbed:~$ exit
logout
#退出再重新登录
  • 到Arista网站下载cEOS docker镜像
    • 先要注册账号,然后打开https://www.arista.com/en/support/software-download
    • 我下载的是cEOS64-lab-4.25.8M.tar.xz
    • 下载的镜像放在
ljyfree@testbed:~/packages$ sha256sum cEOS64-lab-4.25.8M.tar.xz 
71161e2973579fd1fa4045cefd530176d047dc8c068279965fb5e404d604f43d  cEOS64-lab-4.25.8M.tar.xz
ljyfree@testbed:~/packages$
  • 加载镜像并设置tag
ljyfree@testbed:~/packages$ docker import cEOS64-lab-4.25.8M.tar.xz ceosimage:4.25.8M ceosimage:4.25.8M
  • 下载最新的sonic-vs镜像,这个镜像会不时更新
ljyfree@testbed:~/packages$ wget "https://sonic-build.azurewebsites.net/api/sonic/artifacts?branchName=master&platform=vs&target=target/sonic-vs.img.gz" -O sonic-vs.img.gz
ljyfree@testbed:~/packages$ sha256sum sonic-vs.img.gz 
6f01483503b08c19ff199d74f06b682647cc0110dbbf8f21653a3eecdc118a6d  sonic-vs.img.gz
ljyfree@testbed:~/packages$
  • 拷贝到目标目录
ljyfree@sonic-testbed:~/packages$ mkdir -p ~/sonic-vm/images/
ljyfree@sonic-testbed:~/packages$ cp sonic-vs.img ~/sonic-vm/images/
  • 设置网桥
ljyfree@sonic-testbed:~/sonic-mgmt/ansible$ sudo ./setup-management-network.sh
ljyfree@sonic-testbed:~/sonic-mgmt/ansible$ sudo ./setup-management-network.sh
