通过YAML创建Azure Container App时遇JSON解析失败问题

错误执行命令及输出 #

kallel [ ~ ]$ az containerapp create -n my-containerapp --environment fk-apps-env-module -g fkallel-sbx2   --yaml "hello.yaml"
Additional flags were passed along with --yaml. These flags will be ignored, and the configuration defined in the yaml will be used instead
Bad Request({"type":"https://tools.ietf.org/html/rfc9110#section-15.5.1","title":"One or more validation errors occurred.","status":400,"errors":{"$":["The JSON value could not be converted to System.Boolean. Path: $ | LineNumber: 0 | BytePositionInLine: 4."]},"traceId":"00-b6560ac8c2d75ca90655be0591a4712a-b9180e8e23de9eb7-01"})

问题原因及解决方法 #

问题出在YAML配置的traffic节点下的latest_revision字段——Azure容器应用的API要求该字段使用驼峰命名latestRevision，而非下划线分隔格式。YAML转JSON后，下划线格式的字段无法被后端正确识别为布尔值类型，从而触发转换错误。

修改YAML中的对应字段：
将

latest_revision: true

改为

latestRevision: true

修改后重新执行az containerapp create命令即可解决该错误。
