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

Hi, Thanks for reading my blog. Now coming back to your issue, well, the problem with the first error is that you are using my docker hub registry URL in your build, so it will not work as you don't have credentials for that. The correct way is the create your Docker Hub account and then use those login credentials in the maven settings.xml file as mentioned in the blog.

Thanks Ashish for quick reply!

Now connection timeout issue has been resolved.

However, when i access localhost/hello its giving below error

D:\Senthil\Java\spring-jib\spring-jib>curl localhost:8080/hello {"timestamp":"2021-04-06T10:19:52.588+00:00","status":404,"error":"Not Found","message":"","path":"/hello"}

SpringBoot container started and running in http 8080 port not sure why i still cant access the endpoint.

Please advise Ashish

Thanks again

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

Senthilkumar Do you mind sharing the docker run command you have used to start the container?.

Senthilkumar I have never explicitly passed username and password while running jib:build. You can check the documentation for more details. I have not passed any credentials explicitly in the demo video, so it should pick up from the setttings.xml file.

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!
