kubectl apply执行loadbalancer.yaml报错YAML转JSON失败第4行存非法字符

你收到的YAML解析报错是因为配置文件存在缩进层级错误，虽然没有使用制表符，但字段归属的层级不符合YAML语法规范：

• 你配置中两个Pod资源的nodeSelector字段是spec的子属性，必须缩进在spec的层级下，当前配置里nodeSelector和spec为同一缩进层级，属于非法结构，YAML解析器无法识别该位置的字段，因此抛出无法启动token的报错。

apiVersion: v1

spec: 
 type: LoadBalancer
 selector: 
  app: server
 ports: 
 - name: server-port

你可以在提交配置到集群前，先执行本地校验命令确认语法正确：
kubectl apply -f loadbalancer.yaml --dry-run=client
