DockerforWindows ：JenkinsInstallation：java.security.SignatureException：签名长度不正确：得到 512 但期待 256

Question

I have installed docker for windows and am using windows10 64 bit

I have used the below docker command initially to install jenkins in docker

docker run jenkins:2.60.3 

The above command successfully ran

And now i am trying to port using the below command

docker run -p 8080:8080 jenkins:2.60.3

And am getting the below error message

java.security.SignatureException: Signature length not correct: got 512 but was expecting 256

I have installed latest jdk kit and checked if the issue gets fixed. But also the same error persists.

Base on the Deprecation Notice at https://hub.docker.com/_/jenkins the "jenkins" image has been deprecated for over 2 years in favor of the " jenkins/jenkins " image.

The below works fine on my Windows10 Pro:

docker run -p 8080:8080 jenkins/jenkins:lts-jdk11
