Hi,

I tried to reproduce the problem but building the hello-world microservice worked for me. I deleted all cached Docker images to build from scratch and it still works. Specifically, the step that fails for you (installing packages on the alpine base image) works.

Could this be a network issue on your side? Are you using a proxy or a VPN that might be terminating TLS connections? Can you try from a different network?

Best regards,
Harald

It might be related to some security software like Zscaler running in your network, see:

This is caused because you don’t have the correct certificate setup. Your local environmernt is probably missing the cert or CA that is being given by the remote host.

The easiest solution, but also not very secure is to tell maven to ignore SSL errors by adding the following option.

-Dmaven.wagon.http.ssl.insecure=true

regards,
John.
