#docker - May 2019

Has anyone done docker image promotion on Artifactory? (specifically through jenkins or similar CI)

For Alpine Linux container based implementations.

☝️

Versions of the Official Alpine Linux Docker images (since v3.3) contain a NULL password for the `root` user. This vulnerability appears to be the result of a regression introduced in December of 2015. Due to the nature of this issue, systems deployed using affected versions of the Alpine Linux container which utilize Linux PAM, or some other mechanism which uses the system shadow file as an authentication database, may accept a NULL password for the `root` user.

Superb recent comment on docker's support for volume mount +(uid/gid/access bits) support, and how hacks around this missing basic feature are now appearing in helm charts.

do you guys create a non-root user in all your dockerfiles?

@btai yes

sometimes it just works with the nobody:nobody user/group present inside the docker image.
