java - Openshift 部署 F8：无法访问集群以检测模式：sun.security.validator.ValidatorException

问题描述

我正在使用 fabric8 maven deploy 部署示例 springboot 应用程序。构建失败并出现 SSLHandshakeException。

F8: Cannot access cluster for detecting mode: sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target

Failed to execute goal io.fabric8:fabric8-maven-plugin:3.1.80.redhat-000010:build (default) on project fuse-camel-sb-rest: Execution default of goal io.fabric8:fabric8-maven-plugin:3.1.80.redhat-000010:build failed: An error has occurred. sun.security.validator.ValidatorException: PKIX path building failed: sun.security.provider.certpath.SunCertPathBuilderException: unable to find valid certification path to requested target -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal io.fabric8:fabric8-maven-plugin:3.1.80.redhat-000010:build (default) on project fuse-camel-sb-rest: Execution default of goal io.fabric8:fabric8-maven-plugin:3.1.80.redhat-000010:build failed: An error has occurred.

因此，我从 Openshift webconsole 下载了公共证书并将其添加到 JVM 使用

C:\...\jdk.\bin>keytool -import -alias rootcert -file C:\sample\RootCert.cer -keystore cacerts

并收到消息，它已成功添加到密钥库，并且 list 命令显示添加的证书。

    C:\...\jdk.\bin>keytool -list -keystore cacerts
Enter keystore password:
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 2 entries

rootcert, May 18, 2018, trustedCertEntry,
Certificate fingerprint (SHA1): XX:XX:XX:..........

但是 mvn:fabric8 deploy 构建仍然失败并出现同样的异常。

有人可以阐明这个问题吗？我错过了什么吗？

解决方案

以下适用于 MacOS：

要安装的证书是在浏览器 URL 栏上找到的证书；
在 Firefox 上（至少）单击挂锁图标 URL 左侧的挂锁，然后继续向下Connection > / More Information / View Certificate / Details，最后Export...允许您在本地保存证书。

在命令行上，确定正在使用哪个 JRE maven：

$ mvn --version
Apache Maven 3.5.4 (1edded0938998edf8bf061f1ceb3cfdeccf443fe; 2018-06-17T19:33:14+01:00)
Maven home: /Users/.../apache-maven-3.5.4
Java version: 1.8.0_171, vendor: Oracle Corporation, runtime: /Library/Java/JavaVirtualMachines/jdk1.8.0_171.jdk/Contents/Home/jre
Default locale: en_GB, platform encoding: UTF-8
OS name: "mac os x", version: "10.12.6", arch: "x86_64", family: "mac"

您可能需要成为“root”才能更新 cacerts 文件。

$ sudo keytool -import -alias my-openshift-clustername -file /Users/.../downloads/my-cluster-cert.crt -keystore $JAVA_HOME/jre/lib/security/cacerts
Password: {your password for sudo}
Enter keystore password: {JRE cacerts password, default is changeit}
... keytool prints certificate details...
Trust this certificate? [no]:  yes
Certificate was added to keystore

验证证书确实添加成功：

$ keytool -list -keystore $JAVA_HOME/jre/lib/security/cacerts
Enter keystore password: changeit
Keystore type: JKS
Keystore provider: SUN

Your keystore contains 106 entries

...other entries, in no particular order...
my-openshift-clustername, 25-Feb-2019, trustedCertEntry,
Certificate fingerprint (SHA1): F4:17:3B:D8:E1:4E:0F:AD:16:D3:FF:0F:22:73:40:AE:A2:67:B2:AB
...other entries...
