我有一种情况，我有一个命令的输出，像这样，

192.168.1.84
192.168.1.85

我想使用它，并在另一个文件中进行更改，即像这种形式一样，一个接一个地添加这个 IP 地址。在ResourceRecordSet行下方。

ubuntu@kops:/mujahid$ cat change-resource-record-sets.json
{
    "Comment": "Update record to reflect new IP address of home router",
    "Changes": [
        {
            "Action": "UPSERT",
            "ResourceRecordSet": {
                "Name": "testing.mak.online.",
                "Type": "A",
                "TTL": 60,
                "ResourceRecords": [
                    {
                        "Value": "192.168.1.84"
                    },
                    {
                        "Value": "192.168.1.5"
                    }
                ]
            }
        }
    ]
}

我正在运行这本剧本，但它在最后一项任务中失败了。从 ubuntu 主机运行它，，

---
 - hosts: all
   become: yes
   tasks:
   - name: Copy certificate files.
     copy:
        src: "{{ item.src }}"
        dest: "{{ item.dest }}"
        owner: root
        group: root
        mode: 0644
     with_items:
     -  {  src: "/registry_certs/domain.crt", dest: "/usr/local/share/ca-certificates/ca.crt" }

   - command: sudo apt-get install --reinstall ca-certificates
   - command: sudo update-ca-certificates

   - name:  "just force systemd to reread configs (2.4 and above)"
     systemd:
       name: "{{ item }}"
       state: started
       daemon_reload: yes
     with_items:
     - docker
     - kubelet

错误

ubuntu@kops:/etc/ansible$ sudo ansible-playbook certificate_new.yml -l aws  --syntax-check
ERROR! no action detected in task

The error appears to have been in '/etc/ansible/certificate_new.yml': line 18, column 6, but may
be elsewhere in the file depending on the exact syntax problem.

The offending line appears to be:


   - name:  "just force systemd to reread configs (2.4 and above)"
     ^ here

我已经在 docker 中设置了一个私有注册表，可以通过域“makdom.ddns.net”访问，我可以在本地登录推送和拉取图像，即使是从 kubes 节点我也可以做到这一点，

但是当我编写一个 kubes 部署文件时，它无法从私有注册表中提取图像并且失败。

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
  name: ssh-deployment

  template:

        - name: nodejs-port
          containerPort: 22
      imagePullSecrets:
      - name: myregistrykey

有没有人如何连接到docker主机uri？我需要设置 jenkins 在 docker 主机上执行任务？？这是 docker 主机信息。这是基于 Ubuntu 的机器。
