@@ -20,3 +20,26 @@ To start the JVM in debug mode, set the Java system property `DEBUG=true`:
 The JVM will then listen for a debugger to be attached on port 7102.  The JVM will _not_ wait for
 the debugger to be attached before starting Clouddriver; the relevant JVM arguments can be seen and
 modified as needed in `build.gradle`.

+修复了spinnaker对接AWS中国区不可用的几个问题
+
+问题1：竟价地址请求错误
+    com.netflix.spinnaker.clouddriver.aws.provider.agent.AmazonInstanceTypeCachingAgent
+问题2：没有根据区域设置合适的endpoint，默认的sts.amazonaws.com无法认证cn-north-1
+    com.netflix.spinnaker.clouddriver.aws.security.NetflixSTSAssumeRoleSessionCredentialsProvider
+	PS：目前先硬编码为北京1区，后续做优化
+问题3：assumeRole全称的生成未考虑中国区的特殊性，以致中国区的assumeRole全称错误
+    解决方案：assumeRole必须使用全称，即arn:aws-cn:iam::048625849086:role/spinnakerManaged
+
+源码启动方式：
+```
+nohup sh -c "./gradlew --daemon 2>&1 | tee /tmp//clouddriver.log | cat >/dev/null" >/dev/null &
+```
+
+如果需要jvm远程调试：
+```
+nohup sh -c "./gradlew -DDEBUG=true --daemon 2>&1 | tee /tmp//clouddriver.log | cat >/dev/null" >/dev/null &
+```
