Container Registry

Simplifyd Cloud includes a built-in container registry at sdcr.io. Each workspace can have one registry namespace, giving you a private path to push and pull Docker images:

sdcr.io/<registry-name>/<image>:<tag>

Registry namespaces are a workspace-level resource — they are shared across all projects in the workspace.

Creating a registry

1. Open any project inside the workspace.
2. Go to Project Settings → Registry.
3. Enter a registry name (lowercase letters, digits, and hyphens; 2–64 characters). The name is pre-filled with your project name as a suggestion — you can change it.
4. Click Create Registry.

Once created, the full push URL (sdcr.io/<name>) is displayed and ready to use.

Pushing an image

There are two ways to push images to your registry.

Using the edge CLI (recommended)

The edge registry push command handles authentication, tagging, and pushing in one step — no manual docker login needed:

# Build your image
docker build -t my-app:latest .

# Push to your workspace registry
edge registry push my-app:latest -w <workspace-slug>

→ Registry: my-registry (sdcr.io/my-registry)
→ Pushing to sdcr.io/my-registry/my-app:latest
✓ Successfully pushed sdcr.io/my-registry/my-app:latest

The CLI fetches short-lived credentials from the API automatically. See the CLI registry docs for the full reference.

Using Docker directly

You can also push using standard Docker commands:

# Log in
docker login sdcr.io

# Tag your local image
docker tag my-app:latest sdcr.io/<registry-name>/my-app:latest

# Push
docker push sdcr.io/<registry-name>/my-app:latest

Once pushed by either method, reference the image in a Docker service:

sdcr.io/<registry-name>/my-app:latest

Deleting a registry

Deleting a registry permanently removes the registry and all images it contains.

1. Go to Project Settings → Registry.
2. Scroll to the Danger Zone section.
3. Click Delete Registry.
4. Confirm in the dialog.
