vagrant(6)package基于当前虚机打包box

目的

当前虚机做了优化，想基于此虚机打包xx.box当作基础镜像

1.检查vagrant默认insecure_private_key

ll ~/.vagrant.d/insecure_private_key

➜  .vagrant.d ll ~/.vagrant.d/insecure_private_keys 
total 32
-rw-------  1 mvpbang  staff   411  4  2  2024 vagrant.key.ed25519
-rw-r--r--  1 mvpbang  staff    98  3  5 15:58 vagrant.key.ed25519.pub
-rw-------  1 mvpbang  staff  1675  4  2  2024 vagrant.key.rsa
-rw-r--r--  1 mvpbang  staff   381  3  5 15:58 vagrant.key.rsa.pub

默认情况~/.vagrant.d/insecure_private_keys只有私钥，需要人工生成对应公钥(添加到需要打包镜像虚机中)

ssh-keygen -y -f ~/.vagrant.d/insecure_private_keys/vagrant.key.rsa > ~/.vagrant.d/insecure_private_keys/vagrant.key.rsa.pub

ssh-keygen -y -f ~/.vagrant.d/insecure_private_keys/vagrant.key.ed25519 > ~/.vagrant.d/insecure_private_keys/vagrant.key.ed25519.pub

经过测试，默认~/.vagrant.d/insecure_private_key 是~/.vagrant.d/insecure_private_keys/vagrant.key.rsa

2.添加默认公钥到虚机内

vagrant.key.rsa.pub

/home/vagrant/.ssh/authorized_key
xxxxx  vagrant secure public key

添加到第一行

3.检查第一块网卡nat类型

4.关机打包box

4.1关机
vagrant halt

4.2获取实例名字
VBoxManage list vms

4.3package
vagrant package --base vgt-c7-101

5.导入box

vagrant box add centos7.o ./package.box

6.验证新的box

6.1Vagrantfile

Vagrant.configure("2") do |config|
    config.vm.box = "centos7.o"
    config.vm.hostname = "vgt-c7-102"
    config.vm.network "private_network", ip: "172.24.20.102", hostname: true
    config.vm.synced_folder ".", "/vagrant", disabled: true
    config.vm.provider "virtualbox" do |vb|
      vb.memory = 2048
      vb.cpus   = 2
      vb.name   = "vgt-c7-102"
    end
end

6.2up

vagrant up
