Glossary

Core Concepts

Agent

A software component installed on deployment targets that receives and executes deployment tasks. Agents communicate with the orchestrator via mTLS and execute deployments locally on the target.

Approval

A human decision to authorize a promotion request. Approvals may require multiple approvers and enforce separation of duties.

Approval Policy

Rules defining who can approve promotions to specific environments, including required approval counts and SoD requirements.

Blue-Green Deployment

A deployment strategy using two identical production environments. Traffic switches from "blue" (current) to "green" (new) after validation.

Canary Deployment

A deployment strategy that gradually rolls out changes to a small subset of targets before full deployment, allowing validation with real traffic.

Channel

A version stream for components (e.g., "stable", "beta", "nightly"). Each channel tracks the latest compatible version.

Component

A deployable unit mapped to a container image repository. Components have versions tracked via digest.

Compose Lock

A Docker Compose file with all image references pinned to specific digests, ensuring reproducible deployments.

Connector

A plugin that integrates Release Orchestrator with external systems (registries, CI/CD, notifications, etc.).

Decision Record

An immutable record of all gate evaluations and conditions considered when making a promotion decision.

Deployment Job

A unit of work representing the deployment of a release to an environment. Contains multiple deployment tasks.

Deployment Task

A single target-level deployment operation within a deployment job.

Digest

A cryptographic hash (SHA-256) that uniquely identifies a container image. Format: sha256:abc123...

Drift

A mismatch between the expected deployed version (from version sticker) and the actual running version on a target.

Environment

A logical grouping of deployment targets representing a stage in the promotion pipeline (e.g., dev, staging, production).

Evidence Packet

An immutable, cryptographically signed record of deployment decisions and outcomes for audit purposes.

Freeze Window

A time period during which deployments to an environment are blocked (e.g., holiday code freeze).

Gate

A checkpoint in the promotion workflow that must pass before deployment proceeds. Types include security gates, approval gates, and custom policy gates.

Promotion

The process of moving a release from one environment to another, subject to gates and approvals.

Release

A versioned bundle of component digests representing a deployable unit. Releases are immutable once created.

Rolling Deployment

A deployment strategy that updates targets in batches, maintaining availability throughout the process.

Rollback

The process of reverting to a previous release version when a deployment fails or causes issues.

Security Gate

An automated gate that evaluates security policies (vulnerability thresholds, compliance requirements) before allowing promotion.

Separation of Duties (SoD)

A security principle requiring that the person who requests a promotion cannot be the same person who approves it.

Step

A single unit of work within a workflow template. Steps have types (deploy, approve, notify, etc.) and can have dependencies.

Target

A specific deployment destination (host, service, container) within an environment.

Tenant

An isolated organizational unit with its own environments, releases, and configurations. Multi-tenancy ensures data isolation.

Version Map

A mapping of image tags to digests for a component, allowing tag-based references while maintaining digest-based deployments.

Version Sticker

Metadata placed on deployment targets indicating the currently deployed release and digest.

Workflow

A DAG (Directed Acyclic Graph) of steps defining the deployment process, including gates, approvals, and verification.

Workflow Template

A reusable workflow definition that can be customized for specific deployment scenarios.
