Custom Images [Public Preview] #1019
Description
Value Prop
GitHub's image customization allows developers to use their existing workflow YAML to produce VM images which can be used as the base for their different developer environments. Developers can use the new syntax to take the state of their current environment and save that to an image to be used in future workflows.
Expected Outcome
Custom Images allows developers to gain control over their supply chain and reduce the average duration of their workflows by customizing the software, tools, and files on Actions Hosted runners before a workflow starts. 33% of Actions runs are to set up tools on their machine before they even start to download packages that their application is dependent on. This takes time on every run of that workflow. With custom images developers can now customize those pre-installed tools, saving time by creating a "pre-warmed" machine.
