如何使用我自己的全局 settings.xml 设置官方 Maven docker 映像？

Question

I use docker for the first time in connection with GitLab CI. I am happy that GitLab does most of the work for me. I am using the official maven docker image maven:3-jdk-8 ( https://hub.docker.com/_/maven/ )

Now I would like to set the global settings.xml on that docker image, which contains data to my nexus server for the deploy phase.

I tried to follow this guide: Adding a directory and image in the docker image , but unfortunally I cannot connect to the bash of the docker image.

root@build:~# docker run maven:3-jdk-8 /bin/bash -it
bash: cannot set terminal process group (-1): Inappropriate ioctl for device
bash: no job control in this shell
root@7d62e8b066f7:/# exit

How can I add my own global settings.xml to my maven docker image?

Answer 1

you can create/ build your own image using a Dockerfile extending the existing maven docker image ie maven:3-jdk-8 in your case

And in there you can add a line something like below:-

COPY settings.xml /usr/share/maven/ref/

You can have multiple settings.xml named differently(obviously) and you can use them as per the requirements

like mvn <goal> -s /usr/share/maven/ref/settings-<somename>.xml

goal and someone being different as per the usage
