Hands-On Auto DevOps with GitLab CI - Speeding Up Builds with Cache

The video tutorial explains the use of caching in GitLab CI to optimize build processes. It covers how caching can save time and bandwidth by reusing downloaded dependencies, specifically in a Node.js application. The tutorial demonstrates setting up caching in GitLab CI, including defining cache paths and keys for branch-specific caching. It also shows the impact of caching on build times through testing. Finally, the video introduces the concept of artifacts, which will be covered in the next tutorial.

How does caching differ when applied at the job level versus globally?

What happens during the first run of a job when no cache is available?

Why is it important to recreate the cache after a build?
