CredentialProviderConfig is the configuration containing information about
each exec credential provider. Kubelet reads this configuration from disk and enables
each provider as specified by the CredentialProvider type.
-->
CredentialProviderConfig 包含有关每个 exec 凭据提供程序的配置信息。
Kubelet 从磁盘上读取这些配置信息，并根据 CredentialProvider 类型启用各个提供程序。

CredentialProvider represents an exec plugin to be invoked by the kubelet. The plugin is only
invoked when an image being pulled matches the images handled by the plugin (see matchImages).

CredentialProvider 代表的是要被 kubelet 调用的一个 exec 插件。
这一插件只会在所拉取的镜像与该插件所处理的镜像匹配时才会被调用（参见 <code>matchImages</code>）。

<!--
Each entry in matchImages is a pattern which can optionally contain a port and a path.
Globs can be used in the domain, but not in the port or the path. Globs are supported
as subdomains like '&ast;.k8s.io' or 'k8s.&ast;.io', and top-level-domains such as 'k8s.&ast;'.
Matching partial subdomains like 'app</em>.k8s.io' is also supported. Each glob can only match
a single subdomain segment, so &ast;.io does not match &ast;.k8s.io.
-->
<p><code>matchImages</code> 中的每个条目都是一个模式字符串，其中可以包含端口号和路径。
域名部分可以包含通配符，但端口或路径部分不可以。'&ast;.k8s.io' 或 'k8s.&ast;.io' 等子域名以及
'k8s.&ast;' 这类顶级域名都支持通配符。</p>
<p>对于 'app</em>.k8s.io' 这类部分子域名的匹配也是支持的。
每个通配符只能用来匹配一个子域名段，所以 &ast;.io 不会匹配 &ast;.k8s.io。</p>

<p>镜像与 <code>matchImages</code> 之间存在匹配时，以下条件都要满足：</p>
<ul>
  <!--
  <li>Both contain the same number of domain parts and each part matches.</li>
  <li>The URL path of an imageMatch must be a prefix of the target image URL path.</li>
  <li>If the imageMatch contains a port, then the port must match in the image as well.</li>
