puppet - 复杂的 hiera 查找不起作用

Question

我在 yaml 文件中有以下定义:

keepalived:
    cluster_name: "cluster.example.lan"
    cluster_ip: "192.168.1.10"
    cluster_nic: "eth0"
haproxy:
    bind_address: %{hiera('keepalived::cluster_ip')}

结果是 bind_address我有一个空字符串。

如果我使用 %{hiera('keepalived')}我已经打印了整个哈希，但我只需要 cluster_ip从这个哈希。我如何查找 cluster_ip ?

Answer 1

我觉得不是possible:

Hiera can only interpolate variables whose values are strings. (Numbers from Puppet are also passed as strings and can be used safely.) You cannot interpolate variables whose values are booleans, numbers not from Puppet, arrays, hashes, resource references, or an explicit undef value.

Additionally, Hiera cannot interpolate an individual element of any array or hash, even if that element’s value is a string.

您始终可以将 cluster_ip 定义为变量:

common::cluster_ip: "192.168.1.10"

然后使用它:

keepalived:
    cluster_name: "cluster.example.lan"
    cluster_ip: "%{hiera('common::cluster_ip')}"
    cluster_nic: "eth0"

haproxy:
    bind_address: "%{hiera('common::cluster_ip')}"
