修复Packer Provisions Shell Could not get lock /var/lib/dpkg/lock-frontend - open问题

问题背景

在使用packer打包镜像的时候, 需要安装ansible, 而安装ansible之前, 主要

apt update

燃鹅, packer报错说

amazon-ebs: E: Could not get lock /var/lib/dpkg/lock-frontend - open (11: Resource temporarily unavailable)
amazon-ebs: E: Unable to acquire the dpkg frontend lock (/var/lib/dpkg/lock-frontend), is another process using it?

解决方案

Provision 加一步, 先 sleep 5分钟, 等系统开机时候的安全检查结束了, 便可成功

    "provisioners": [
      {
        "type": "shell",
        "inline": [
          "sleep 300",
          "sudo apt-get install -y ansible"
        ]
      },

如果不确定需要多久, 可以用另外的方法, 可以缩减时间.

      {
        "type": "shell",
        "inline": [
          "while sudo lsof /var/lib/dpkg/lock-frontend ; do sleep 10; done;",
          "sudo apt-get install -y ansible"
        ]
      },
