失败！=> { "msg" ： "'dict object' has no attribute 'stdout'" }

Question

我试图获取工作节点的IP地址和主机名并将其写入主/根/主机文件。收到错误，失败！=> {"msg"： "'dict object' 没有属性 'stdout'"}

- name: set glusterfs device in hostfile
  shell: echo "{{ name }} glusterfs_devices='[ "/dev/abcd" ]'"
  register: opt_gluster
  when: type == "worker"
- name: add glusterfs
  lineinfile:
    dest: /root/hosts
    line: "{{item}}"
    insertafter: EOF
  with_items:
       - "{{ opt_gluster.stdout }}"
  when: type == "master"

{"msg": "'dict object' has no attribute 'stdout'"}

Answer 1

我认为问题出在 when 语句

- name: add glusterfs
  lineinfile:
    dest: /root/hosts
    line: "{{item}}"
    insertafter: EOF
  with_items:
       - "{{ opt_gluster.stdout }}"
  when: type == "master"

我认为它缺少一个

when: type == "master" and opt_gluster.stdout is defined

因为当你在一个节点上时，谁不会成为worker opt_gluster不会有一个标准输出，因为它正在跳过。
