Hi Ashish, All setup are done now when i try to execute docker run command using docker run -it --rm -p 8080:8080 senthil131720/demo getting below error. I have installed Docker in my machine. Please advice. Thanks again! D:\Senthil\Java\spring-jib\spring-jib>docker run -it --rm -p 8080:8080 senthil131720/demo Error: -jar requires jar file specification Usage: java [options] <mainclass> [args...] (to execute a class) or java [options] -jar <jarfile> [args...] (to execute a jar file) or java [options] -m <module>[/<mainclass>] [args...] java [options] --module <module>[/<mainclass>] [args...] (to execute the main class in a module) or java [options] <sourcefile> [args] (to execute a single source-file program)

Hi Ashish, Moreover, despite configuring docker hub username and password in maven settings.xml file, we need to explicitly pass username and password when we executing build jib command. Please advise. Thanks again mvn compile jib:build -Djib.to.auth.username=user -Djib.to.auth.password=pass

Thanks Ashish for quick reply! Now connection timeout issue has been resolved.

Please advise Ashish Thanks again

Hi Ashish, I have created test account in Docker Registry. However, still getting below error. Please suggest. Build image failed, perhaps you should make sure your credentials for 'registry.hub.docker.com/senthil131720/spring-boot-jib-image' are set up correctly
