Linux via SSH
Standard SSH keys or password auth. Works with any Linux server that has Docker installed.
Agentless Deployment
Deploy to Servers Without Installing Agents
Connect to your Linux and Windows servers using standard protocols. Deploy containers with progressive strategies and roll back instantly when needed.
True Agentless Deployment
No daemons to install. No ports to open. Just connect using the credentials you already have.
Windows via WinRM
Native Windows remoting. Deploy to Windows Server with Docker or containers on Windows.
Zero footprint on your servers. Stella connects, deploys, verifies, and disconnects — leaving only your application running.
Why Agentless?
Agents mean more attack surface, more updates, more things that can break. Stella deploys without them.
Nothing to Install
No agent packages, no version mismatches, no “agent offline” alerts. Just standard remote access.
Reduced Attack Surface
Every installed daemon is potential attack surface. Stella connects only when deploying, then disconnects.
Full Audit Trail
Every deployment is logged with who, what, when, and why. Evidence for compliance built in.
Simple Operations
Use your existing SSH keys and Windows credentials. No new infrastructure to manage.
Progressive Delivery Strategies
Deploy with confidence using industry-standard strategies that minimize risk and enable quick recovery.
All-at-Once
Rolling
Canary
Blue-Green
Canary Deployments
Deploy to a small percentage of targets first (10%), monitor for issues, then gradually expand to 25%, 50%, and 100%. Automatic rollback on failure at any stage.
10% → 25% → 50% → 100%
Blue-Green Deployments
Run two identical environments. Deploy new version to “green” while “blue” serves traffic. Switch instantly when ready. Switch back instantly if problems arise.
Blue (live) → Green (deploy) → Switch
Deploy with your preferred strategy
$ stella deploy create --release myapp-v2.1.0 --strategy canary
stella deploy promote --job job-uuid --percent 50
stella deploy status --job job-uuidA/B Testing & Traffic Splitting
Route traffic between versions for real-world comparison before full rollout.
- Split traffic by percentage (90/10, 50/50, or custom)
- Compare metrics between versions in production
- Gradually shift traffic as confidence grows
- Instant revert to 100% stable version if needed
Instant Rollback
When something goes wrong, roll back to the exact previous version — not “whatever was there before” but the verified, known-good state.
- Rollback restores the exact container digest that was running before
- No re-pulling “latest” or hoping tags haven’t changed
- One command to return to known-good state
Digest-Verified Rollback
Because Stella tracks exact digests, rollback deploys the identical bytes that were previously running. Same artifact, same behavior, guaranteed.
How Fast?
Blue-green: instant (traffic switch). Canary/rolling: seconds (parallel revert). The previous digest is always cached and ready.
Rollback with one command
$ stella deploy rollback --environment production
Rolling back to myapp-v2.0.0 (sha256:abc123...)
Rollback complete. All targets verified.Every Deployment is Evidence
Stella records what was deployed, who deployed it, and when — with cryptographic proof.
What
Exact container digests deployed to each target
Who
Authenticated deployer identity
When
Timestamped and signed deployment record
