AppMain

@SpringBootApplication
public class DemoApplication {

    public static void main(String[] args) {
        SpringApplication.run(DemoApplication.class, args);
    }
}

控制器

@RestController
public class SampleController {


    @GetMapping("/test")
    public String test(){


        return "Spring Boot running......";
    }
}

当我开始从 OpenShift 拉取时，所有这些都在 git 上，它构建成功，但是在出现错误并且没有部署之后。

我选择了 Java 和 Redhut jboss(tomcat 8)

【问题讨论】：

oc describe pod <failed-build-pod> 的结果是什么？您还可以查看oc get events 以了解项目本身发生了什么。
几乎看起来好像构建的内存不足，但会出现不同的错误。你有什么额外的日志或事件，比如 bibix 建议描述 builder pod 会很好。
我在使用 codecentric/springboot-maven3-centos docker 时遇到了同样的错误

【解决方案1】：

检查构建 yaml 文件中的资源标签。如果不添加如下资源

resources:
limits:
  cpu: '2'
  memory: 2Gi
requests:
  cpu: '1'
  memory: 1Gi
