Sharing Sensitive Data Among GitLab CI Jobs

It is often needed to share data among the jobs in GitLab CI pipelines. Artifacts (and maybe Cache, too) is the utility that GitLab introduces for this purpose.

So, what if this data is sensitive, and we want it not to be easily accessible?

By ‘accessible’, I mean storing the plain data in the disk or letting the plain data be obtained outside the pipeline execution without restriction.

Consider the following definition:

image: alpine:latest

stages: 
  - create-sensitive-data
  - use-sensitive-data

create-sensitive-data: …

artifact artifacts cache data disk encryption gitlab jobs pipelines purpose sensitive sensitive data share sharing utility
