Hi Luis,

thanks for taking time trying to reproduce the issue on your end. I'm running docker on Debian 4.19.208-1 (2021-09-29) x86_64 GNU/Linux.

I finally used another alpine version to be able to continue following the tutorial.

Hi Luis,

unfortunately this section is before the Jenkins introduction, so I do not have any script to check. And due to resources constraint I had to prune Docker images no longer used. I'm afraid I cannot trace back with alpine version I used for sure. But, in the following section where the Docker image is written in a Jenkinsfile I used the maven:3.6.1-jdk-8-alpine.

Thanks

Béatrice
