post_tasks 建议改成 tasks
post_tasks: 不管前面部分成功或者失败，都会被执行，这应该不是我们想要的

这里把 down目录下都复制过去，东西太多了，里面还有离线系统包 packages，会导致执行时间长；
建议只复制需要的tar包即可：coredns*.tar dashboard*.tar heapster*.tar metrics*.tar traefik*.tar，参考如下

  - name: create images directory
    file: dest=/opt/kube/images state=directory
  - name: copy offline images
    copy: src={{ item }} dest=/opt/kube/images/
    with_fileglob:
      - "{{ base_dir }}/down/coredns*.tar"
      - "{{ base_dir }}/down/dashboard*.tar"
      - "{{ base_dir }}/down/heapster*.tar"
      - "{{ base_dir }}/down/metrics*.tar"
      - "{{ base_dir }}/down/traefik*.tar"

这样改的确传输文件的大小和执行时间都能少很多

- name: 导入所有离线镜像
shell: ls /opt/kube/images/*.tar |while read n;do {{ bin_dir }}/docker load -i $n ;done
ignore_errors: true
