我正在将Spring Cloud DataFlow Kubernetes Server部署从1.2.2.RELEASE升级到1.3.1.RELEASE，并使用minikube对其进行测试。
在修复无效的docker URI（docker：to docker：//）并成功查看在shell中注册的应用程序后，对kubernetes服务器的部署最终失败。使用简单的流：
mysource | myprocessor | rabbitsink
Spring Boot sink app 根据pod的日志成功部署并启动。这是该应用程序的成功注册：
app register --name rabbitsink --type sink --uri docker://192.168.99.100:80/myrepo/rabbitsink:current
Successfully registered application 'sink:rabbitsink'
尽管如此，数据流shell的后续输出是：
Command failed org.springframework.cloud.dataflow.rest.client.DataFlowClientException: Invalid docker resource URI: docker:192.168.99.100:80/myrepo/rabbitsink:current
并且该流的其他应用都没有启动。
这里是日志中的堆栈跟踪：

我们最近在spring-cloud/spring-cloud-dataflow#2065中讨论了类似的问题。
正如comment中所强调的那样，Docker资源URI应该是从1.3版本开始的某种格式。
在您的情况下，Docker URI应该是：
dataflow：＆gt; app register --name rabbitsink --type sink --uri docker：myrepo / rabbitsink：current
如果未遵循上述格式，则Shell将通过验证消息快速失败。流不会被部署;也不应该为应用程序显示任何pod。这是我的minikube环境中的验证消息。
命令失败org.springframework.cloud.dataflow.rest.client.DataFlowClientException：无效的docker资源URI：docker：192.168.99.100：80 / myrepo / rabbitsink：current
我建议重新开始。您还可以使用helm-chart（Docs for Minikube is in PR）来简化配置体验。
答案 1 :(得分：0)
这是我需要解决的错误。测试
@Test
public void testDockerResourceProcessingSO() {
DockerResource dockerResource = new DockerResource("192.168.99.100:80/myrepo/rabbitsink:current");
assertThat(ResourceUtils.getResourceWithoutVersion(dockerResource)).isEqualTo("docker:192.168.99.100:80/myrepo/rabbitsink");
assertThat(ResourceUtils.getResourceVersion(dockerResource)).isEqualTo("current");
}
失败。由于这行代码
String dockerResourceUri = dockerResource.getURI().toString();
Assert.isTrue(StringUtils.countOccurrencesOf(dockerResourceUri, ":") == 2,
"Invalid docker resource URI: " + dockerResourceUri)
和dockerResourceUri是docker：192.168.99.100：80 / myrepo / rabbitsink：current
如果使用了船长，还会有另一个问题，因为版本需要遵循＆＃39; semver＆＃39;格式和＆＃39;当前＆＃39;不会有效。我们可以更好地验证docker格式并尽快修复。
我们解决了这个问题后，如果你使用了船长，那么船长就不会喜欢“当前的＆＃39;作为版本名称，它必须是真实的版本号。尚不确定我们是否可以采取任何措施来适应“开发”工作流程＆＃39;当船长的整个要点是管理版本更新时没有版本号。也许我们需要允许“当前＆＃39;”，“最新＆＃39;＆＃39; SNAPSHOT＆＃39;作为允许的版本，并始终在请求更新时重新部署这些应用程序。

这已在1.4.0.RELEASE版本的Spring Cloud Dataflow中修复，并且与本地数据流服务器的1.4.0.RELEASE版本，kubernetes数据流服务器和数据流shell一起使用时效果很好。它适用于Spring Cloud Edgware.SR2和Edgware.SR3。
