7.2. 配置用户代理

流程

• 修改 master 配置文件，使其包含用户代理配置。例如，以下用户代理拒绝 Kubernetes 1.2 客户端二进制、OKD 1.1.3 二进制，以及 POST 和 PUT httpVerb：

  policyConfig:
    userAgentMatchingConfig:
      defaultRejectionMessage: "Your client is too old.  Go to https://example.org to update it."
      deniedClients:
      - regex: '\w+/v(?:(?:1\.1\.1)|(?:1\.0\.1)) \(.+/.+\) openshift/\w{7}'
      - regex: '\w+/v(?:1\.1\.3) \(.+/.+\) openshift/\w{7}'
        httpVerbs:
        - POST
        - PUT
      - regex: '\w+/v1\.2\.0 \(.+/.+\) kubernetes/\w{7}'
        httpVerbs:
        - POST
        - PUT
      requiredClients: null

  Copy to Clipboard Toggle word wrap

  以下示例拒绝与预期客户端不完全匹配的客户端：

  policyConfig:
    userAgentMatchingConfig:
      defaultRejectionMessage: "Your client is too old.  Go to https://example.org to update it."
      deniedClients: []
      requiredClients:
      - regex: '\w+/v1\.1\.3 \(.+/.+\) openshift/\w{7}'
      - regex: '\w+/v1\.2\.0 \(.+/.+\) kubernetes/\w{7}'
        httpVerbs:
        - POST
        - PUT
