## What this PR does This adds three minimal platform variants for small installs, such as arm64 labs, where isp-full is too heavy. They are `isp-slim` for Talos, `isp-slim-generic` for k3s, kubeadm or RKE2, and `isp-hosted-slim` for clusters where the host provides CNI and storage. A slim variant installs only the base platform: the engine, API and dashboard, tenants, ingress and Gateway API. The two non-hosted variants also get LINSTOR. objectstorage-controller stays on too, because cozystack-controller watches BucketClaim unconditionally and crash-loops without that CRD. Everything else is opt-in through `bundles.enabledPackages`, including every paas and naas application and its operator, monitoring, backups, etcd, SeaweedFS, metrics-server, VPA, Multus and MetalLB. The iaas bundle is refused, so there are no VMs and no managed Kubernetes. With the stock preset a slim variant emits 20 Packages (15 for hosted), where isp-full emits 77. On the two non-hosted slim variants, networking is Cilium alone. Without VMs nothing needs Kube-OVN, and Cilium L2 announcements take the place of MetalLB. The admin creates a `CiliumLoadBalancerIPPool` and a `CiliumL2AnnouncementPolicy`, or uses `publishing.externalIPs`. Pod ranges come from `node.spec.podCIDR`, which Talos and k3s allocate by default. `networking.encryption` only drives Kube-OVN IPsec, so the slim variants refuse it instead of silently ignoring it. The tenant application needs its own slim variant. The default one waits on the monitoring, etcd and SeaweedFS applications, so on slim cozystack-basics and tenant-root would never become ready. tenant-rd and cozystack-basics still reference the default variant's artifacts by name. Those artifacts exist anyway, because the PackageSource builds them for every variant. The full variants don't change. I rendered isp-full, isp-full-generic and isp-hosted against main and got byte-identical Packages. The only new output there is the slim variant in the tenant-application PackageSource. Things to know before using it: - An opt-in package does not pull in its dependencies. The presets and the docs list the chains. A package enabled without its chain stays `DependenciesNotReady`. - Slim is for new installs. Switching a live isp-full cluster to isp-slim moves the networking Package from `kubeovn-cilium` to `cilium`, the operator removes the Kube-OVN release, and running pods lose networking. The other Packages are kept by `helm.sh/resource-policy: keep`, so the switch doesn't make the cluster smaller either. - No e2e suite runs a slim variant yet. Helm unit tests cover the presets, opt-in, OIDC, the networking values and both refusals, and a dependency check over every emitted Package passes for all three presets. I installed isp-slim from a build of this branch on a fresh three-node Talos 1.13 cluster (amd64). All Packages and HelmReleases went Ready, with no Kube-OVN, MetalLB, monitoring, backup or KubeVirt pods. From outside, the dashboard and the API answered by name with valid certificates. A LoadBalancer Service got an address from a Cilium pool and answered through L2 announcements. Pod-to-pod traffic across nodes, cluster DNS and a replicated LINSTOR volume worked. Opting in postgres-operator and postgres-application gave a Ready Postgres. That run found the BucketClaim crash-loop above, which is fixed here. The base platform used about 215m CPU and 3.2 GiB of memory, not counting the Kubernetes control plane. ### Screenshots Not a UI change. ### Downstream repositories - [ ] No downstream repository is affected by this change - [x] [cozystack/website](https://github.com/cozystack/website) - follow-up: cozystack/website#718 - [ ] [cozystack/terraform-provider-cozystack](https://github.com/cozystack/terraform-provider-cozystack) - follow-up: - [x] [cozystack/ansible-cozystack](https://github.com/cozystack/ansible-cozystack) - follow-up: cozystack/ansible-cozystack#79 - [x] [cozystack/ccp](https://github.com/cozystack/ccp) - follow-up: cozystack/ccp#23 - [ ] [cozystack/talm](https://github.com/cozystack/talm) - follow-up: - [ ] [cozystack/cozyhr](https://github.com/cozystack/cozyhr) - follow-up: - [ ] [cozystack/cozy-proxy](https://github.com/cozystack/cozy-proxy) - follow-up: - [ ] [cozystack/cozystack-telemetry-server](https://github.com/cozystack/cozystack-telemetry-server) - follow-up: - [ ] [cozystack/external-apps-example](https://github.com/cozystack/external-apps-example) - follow-up: - [ ] [cozystack/examples](https://github.com/cozystack/examples) - follow-up: - [ ] [cozystack/community](https://github.com/cozystack/community) - follow-up: ### Release note ```release-note feat(platform): add the isp-slim, isp-slim-generic and isp-hosted-slim variants. They install only the base platform (engine, dashboard, tenants, ingress, gateway, and LINSTOR outside hosted) with Cilium-only networking and no MetalLB; applications, operators, monitoring, backups, etcd and SeaweedFS are opt-in through bundles.enabledPackages, and the iaas bundle is not available. ``` <!-- This is an auto-generated comment: release notes by coderabbit.ai --> ## Summary by CodeRabbit * **New Features** * Added the `isp-slim`, `isp-slim-generic`, and `isp-hosted-slim` platform variants, with support for PaaS and NaaS bundles. * Slim variants use Cilium networking and include a reduced set of packages by default. Additional packages and their dependencies can be enabled as needed. * **Limitations** * IaaS and the platform encryption toggle are not supported on slim variants. Cilium-native encryption is not configured. <!-- end of auto-generated comment: release notes by coderabbit.ai -->
