CentOS EOL? Mirrorlist not working

[ioudeveldhuis]

Snippet from the output of the build:

2.317 Loaded plugins: fastestmirror, ovl
5.271 Determining fastest mirrors
5.412 Could not retrieve mirrorlist http://mirrorlist.centos.org/?release=7&arch=x86_64&repo=os&infra=container error was
5.412 14: curl#6 - "Could not resolve host: mirrorlist.centos.org; Unknown error"

Since CentOS 7 is EOL the mirror is also down and I am unable to build an image. Is there a way to update this to CentOS 8?

[edit]
I was able to get the build to finish by using the debian JDK and removing the yum install parts.
