Hidde Beydals c0a1099719 helm: only use Digest to calculcate index revision 
In #1001 bits around the Helm repository reconciliation logic were
rewritten, mostly based on the documented behavior instead of the
actual code. This resulted in the reintroduction of a YAML marshal of
the (sorted) index YAML instead of reliance of just the checksum of the
file.

This to take situations into account in which a repository would e.g.
provide a new random order on every generation. However, this approach
is (extremely) expensive as the marshal goes through a JSON -> YAML
loop, eating lots of RAM in the process.

As the further (silently) introduced behavior has not resulted in any
reported issues, I deem this approach safe and better than e.g.
encoding to just JSON which would still require a substantial amount of
memory.

Source controller

CII Best Practices e2e report license release

The source-controller is a Kubernetes operator, specialised in artifacts acquisition from external sources such as Git, Helm repositories and S3 buckets. The source-controller implements the source.toolkit.fluxcd.io API and is a core component of the GitOps toolkit.

overview

Features:

  • authenticates to sources (SSH, user/password, API token)
  • validates source authenticity (PGP)
  • detects source changes based on update policies (semver)
  • fetches resources on-demand and on-a-schedule
  • packages the fetched resources into a well-known format (tar.gz, yaml)
  • makes the artifacts addressable by their source identifier (sha, version, ts)
  • makes the artifacts available in-cluster to interested 3rd parties
  • notifies interested 3rd parties of source changes and availability (status conditions, events, hooks)
  • reacts to Git push and Helm chart upload events (via notification-controller)

See the docs folder for more information.
