Practical deployment blueprints for platform teams turning open-source applications into isolated, operable SaaS environments—without hiding the hard decisions.
Deployment blueprints
Each guide separates what the upstream chart handles from the tenant lifecycle, isolation, secrets, routing, and upgrade controls a managed service still needs.
How to use Vault's Transit secrets engine to provide tenant-scoped envelope encryption without managing thousands of individual keys.
How platform teams can model one Temporal release per tenant and manage persistence, secrets, routing, and upgrades declaratively.
A decision guide for operating dedicated GitLab environments with explicit data, storage, secrets, and upgrade boundaries.
A practical architecture for isolated Airflow environments with tenant-specific executors, secrets, domains, and lifecycle management.
How to operate isolated Grafana releases per customer while keeping chart versions, secrets, domains, and upgrades under one declarative control plane.
A deployment blueprint for customer-specific Harbor registries with dedicated domains, credentials, storage policies, and release lifecycles.
Evaluate release-per-tenant boundaries for teams offering managed or white-label identity infrastructure on Kubernetes.
A production-minded guide to wrapping the n8n Helm chart with per-tenant releases, scoped secrets, domains, configuration, and lifecycle controls.
How to generate default-deny NetworkPolicy for every tenant release while preserving only the DNS, secrets, observability, and edge paths each workload actually needs.
A production-minded guide to installing Canonical Kubernetes, integrating an external HashiCorp Vault, and compiling those primitives into isolated tenant releases with OpenTenant.
How Cloudflare Tunnel, Access policies, Kubernetes, and OpenTenant fit together to give every tenant a private origin, explicit hostname, and reviewable access policy.
How signed source, immutable artifacts, policy admission, and tenant-scoped rollback provenance create a reviewable deployment chain.
How Vault Secrets Operator and External Secrets Operator synchronize tenant credentials—and how OpenTenant limits the resulting rollout to the workloads that actually depend on them.
A secure tenant-domain workflow spanning hostname ownership, Cloudflare DNS, Gateway API routing, cert-manager issuance, readiness, renewal, and offboarding.
Review the control-plane model behind every blueprint.
