The short version

  • Each has a real cost: Packer packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence; Rancher another platform to run and keep available, and an outage in it affects access to everything it manages
  • They diverge on capability: Packer covers Image building, Rancher covers Multi-cluster management.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Packer

  • Packer 1.10.0 and later is licensed under the Business Source License 1.1 with IBM Corporation as licensor, not an OSI open source licence
  • The Additional Use Grant forbids offering Packer to third parties on a hosted or embedded basis in a paid product that competes with IBM's paid versions of Packer
  • Each version converts to the MPL 2.0 Change License only four years after that version is first published, and the Change Date is set separately per version
  • Alternative licensing for uses outside the grant must be arranged with the licensor rather than taken under the public licence

Rancher

  • Another platform to run and keep available, and an outage in it affects access to everything it manages
  • Meaningful overhead if you only operate one or two clusters
  • Version compatibility between Rancher and managed Kubernetes versions needs watching during upgrades
  • Support requires a SUSE subscription; the project itself is community-supported

Source
Rancher: Is Rancher free?

Yes, open source with no licence fee. SUSE sells support subscriptions.

Rancher: Does Rancher work with EKS and GKE?

Yes. It imports and manages existing clusters regardless of who provisioned them, alongside clusters it creates itself.

Rancher: Do I need Rancher for one cluster?

Generally no. Its value appears when cluster count and consistent access control become the problem, which is not the case with one.
