Hey,

for building Docker images we'd like to use internal mirrors
for Debian and Alpine packages, right now Alpine is not supported.

The support of Alpine packages would be a benefit not only
for internal builds on machines without internet access but
also in regards of security as then these packages would be
included in the security scans for projects under Reporting & SCA.

Hey,

The Alpine repository is basically a file repository containing all the packages
along side with an index.

APKINDEX.tar.gz
nodejs-16.16.0-r0.apk

For example files that are stored within the repository. The index
file contains the meta information of all packages and the APK
files are tar.gz archives of the actual package. 2
