如何解决DockerforWindows ：JenkinsInstallation：java.security.SignatureException：签名长度不正确：得到 512 但期待 256
我已经为 windows 安装了 docker 并且正在使用 windows10 64 位
我最初使用以下 docker 命令在 docker 中安装 jenkins
docker run jenkins:2.60.3
以上命令运行成功
现在我正在尝试使用以下命令进行移植
docker run -p 8080:8080 jenkins:2.60.3
并且收到以下错误消息
java.security.SignatureException: 签名长度不正确：得到 512 但期待 256
我已经安装了最新的 jdk 套件并检查了问题是否得到解决。但同样的错误仍然存在。

解决方法
根据 https://hub.docker.com/_/jenkins 的弃用通知，“jenkins”图像已弃用 2 年多，取而代之的是“jenkins/jenkins”图像。
以下在我的 Windows10 Pro 上运行良好：
docker run -p 8080:8080 jenkins/jenkins:lts-jdk11
