The CLI is a statically linked Go binary and is used to discover, install and update tools.
Tools are defined by...
manifest.yaml contains metadata about the tool
Dockerfile packages the tool into a container image
Every tool is stored in a dedicated container image
metadata contains JSON of all manifest.yaml
Renovate keeps tool versions up-to-date
