为什么kubespray ansible无法与主机匹配

如何解决为什么kubespray ansible无法与主机匹配

我是通过kubespray安装kubernetes的，我的kubespray版本是v2.11.0，我按照官方文档逐步进行安装。但是当我执行“ ansible-playbook -i清单/mycluster/hosts.yml --become --become-user = root cluster.yml”时，我得到以下与主机不匹配的信息。

root@yinkai01:~/kubespray# ansible-playbook -i inventory/mycluster/hosts.yml --become --become-user=root cluster.yml

我是主持人Yaml。我认为这与hosts.yaml无关，如下所示：

root@yinkai01:~/kubespray# cat inventory/mycluster/hosts.yaml 
all:
  hosts:
    node1:
      access_ip: 10.138.18.194
      ip: 10.138.18.194
      ansible_host: 10.138.18.194
    node2:
      access_ip: 10.138.18.195
      ip: 10.138.18.195
      ansible_host: 10.138.18.195
    node3:
      access_ip: 10.138.18.196
      ip: 10.138.18.196
      ansible_host: 10.138.18.196
  children:
    kube-master:
      hosts:
        node2:
        node1:
    kube-node:
      hosts:
        node3:
        node2:
        node1:
    etcd:
      hosts:
        node3:
        node2:
        node1:
    k8s-cluster:
      children:
        kube-node:
        kube-master:
    calico-rr:
      hosts: {}
root@yinkai01:~/kubespray#

有人可以告诉我，我在哪里错了？

解决方法

只需在您的命令行中更改文件名（显然是拼写错误）：

inventory/mycluster/hosts.yml

通过

inventory/mycluster/hosts.yaml

此警告可以帮助您：

 [WARNING]: No inventory was parsed,only implicit localhost is available
