构建k8s镜像的问题

[guinanlin]

构建k8s的镜像的时候, 有这么2个问题,还有一个疑问:

1. 如下的 iso_url iso_checksum的原先地址已经做了更改, source可以改一下:
   `[root@test001 kubernetes]# pwd
   /root/service-images/kubernetes
   [root@test001 kubernetes]# cat k8s-centos-7.json
   {
   "builders": [{
   "type": "qemu",
   "accelerator": "kvm",
   "qemuargs": [
   ["-m", "2048M"],
   ["-smp", "cpus=1,maxcpus=16,cores=4"]
   ],
   "disk_interface": "virtio",
   "disk_compression": false,
   "disk_size": 30720,
   "format": "qcow2",
   "net_device": "virtio-net",

    "iso_url": "https://mirrors.aliyun.com/centos/7/isos/x86_64/CentOS-7-x86_64-Minimal-2009.iso",
    "iso_checksum": "07b94e6b1a0b0260b94c83d6bb76b26bf7a310dc78d7a9c7432809fb9bc6194a",
    "iso_checksum_type": "sha256",
   
    "vm_name": "k8s-centos7-base",
    "output_directory": "./_output/k8s",
   

2. 执行的时候,总是停在如下的位置过不去: Waiting for SSH to become available[root@test001 service-images]# make k8s
./tools/build-image.sh ./kubernetes/k8s-centos-7.json
qemu output will be in this color.

3. 这个如果要构建k8s的其他版本, 是不是只要改scripts/k8s/install-kubeadm.sh 里头的这个语句就可以
   yum install --assumeyes bridge-utils conntrack-tools jq kubelet-1.14.1-0 kubeadm kubectl

即使我做了如下的操作, 再去运行构建脚本,也是不行的.
