Operations and Deployment

Operate heterogeneous targets with one release model

Deploy across Docker, Compose, SSH, and WinRM using digest identified artifacts. Agentless runtime and offline capable workflows keep control in your environment.

What this means for your business

Run one release process across Linux and Windows targets without forcing Kubernetes adoption. Stella links deployment actions to policy evidence so operations and audit stay aligned.

What this operating model covers

Image and artifact analysis

SBOM generation, vulnerability matching, and VEX handling for each releasable artifact.

Reachability based prioritization

Static, manifest, and runtime context filters findings down to exploitable risk.

Promotion control

Move artifacts through environments only after policy and approval requirements are met.

Progressive delivery

Canary, blue green, and rollback workflows with traceable change history.

Evidence retention

Decision Capsules preserve policy inputs, approvals, and verdicts for later verification.

Offline continuity

Air-gapped sites receive signed update kits and keep release control without internet access.

Non-Kubernetes first

Most release platforms prioritize Kubernetes paths. Stella treats non-Kubernetes targets as first class and keeps the same promotion model across each runtime.

Docker Host

Direct container deployment to Docker hosts.

Docker Compose

Multi-container application deployment.

AWS

and Fargate task deployments.

HashiCorp

job deployments and updates.

SSH Targets

Linux/Unix targets over SSH.

WinRM Targets

Windows targets over WinRM.

Scripted (.NET 10) targets are also supported: custom deployment logic runs through the.NET scripting engine when a rollout does not fit the built-in target types.

Deployment target count is not restricted by pricing tier.

Digest-first release identity

Releases are tracked by immutable digests rather than mutable tags, ensuring the artifact scanned and approved is the artifact deployed.

Immutable artifact identity

Digest pinning prevents drift between security analysis, approval, and runtime deployment.

Promotion provenance

Each promotion records source digest, policy inputs, and approval events in signed evidence.

Deployment patterns

A/B testing

Route controlled traffic percentages to compare behavior before full rollout.

Canary release

Promote to a small subset first and expand only when health criteria remain stable.

Blue/Green

Run previous and candidate versions in parallel and switch traffic in a controlled cutover.

Instant rollback

Return to a prior digest quickly while preserving full evidence of forward and rollback actions.

Offline operation without control loss

Policy decisions and verification remain available without external network access. Feed and artifact updates arrive through signed transfer bundles.

Offline Update Kit

Signed package containing everything needed to refresh disconnected environments.

  • Vulnerability feeds from 38 sources
  • Container images for all components
  • Provenance data and SBOMs
  • Delta updates for efficient transfer
No mandatory external egress

Core release and evidence workflows execute within sovereign networks.

  • Local vulnerability database
  • Offline signature verification
  • Deterministic replay without network
  • No mandatory telemetry (opt-in only, disabled by default)
Terminal
$ stella offline import --bundle stella-ouk-2026-01-20.tar.zst --verify-dsse --verify-rekor

Configurable crypto profiles

Select cryptographic profiles to match regional requirements while preserving one release workflow.

HSM and PKCS#11 integration

Use hardware backed keys for signing and verification operations.

Multi profile signing

Apply multiple signature profiles to a single artifact for cross jurisdiction acceptance.

Infrastructure integration

HashiCorp Vault

Use external secret stores for deployment and signing workflows.

HashiCorp Consul

Integrate service discovery and environment metadata where needed.

Container registries

Connect to standard OCI registries in cloud or on premises deployments.

SCM webhooks

Trigger workflows from repository events across common SCM platforms.

Notifications

Route release and policy events to operational channels and on call systems.

Plugin system

Extend workflows with custom connectors and execution steps.

Contact the team for sizing beyond listed guidance.

Recommended production baseline

4 vCPU, 16 GB RAM, 50 GB storage. Docker Engine 23.0+ with Compose v2. This is the starting point for production, not the smallest configuration that runs — headroom above it grows with environments and scan volume.

Headroom for larger estates

8 vCPU, 16 GB RAM and 200 GB SSD give headroom above the measured 4 vCPU / 16 GiB baseline. This is guidance for a larger single instance, not a clustered configuration.

Deployment architecture

Single-node deployment

Compose based topology for evaluation and smaller production footprints.

  • 4 vCPU, 16 GiB RAM — runs the full suite
  • PostgreSQL 16+, Valkey 8.0+
  • 50 GiB SSD for cache and evidence

Inputs from CI, registries, and advisory feeds are normalized into one decision path. Each gate adds signed evidence tied to the artifact digest.

Production operations due diligence

Use this checklist to scope operational effort before production rollout. Start at the topology that matches your estate and harden from there.

TopologyControl PlaneData PlaneTypical Use
Shipped bundleSingle-node services with one worker poolSingle Postgres, single object store, single queue/cacheEvaluation and policy tuning
Backup and restore

Define RPO/RTO for Postgres and evidence object storage. Validate restore with signed capsule replay, not only service health checks.

Upgrade and rollback

Promote platform updates by digest between non-production and production. Keep last-known-good digests and runbooks for fast rollback.

Ops evidence

Track change windows, approvers, and exported evidence packs per upgrade so procurement and audit teams can verify operating discipline.

Doctor self-diagnostics

Self-serve diagnostics are built in. stella doctor runs 110+ checks across 16 domains: connectivity, permissions, registry access, configuration, and license status. Most problems are resolved from its output without a support ticket, and Doctor is available on every tier including Free.
