Deployment Rollback

Go to Terms and Definitions

Deployment Rollback is a Rollback that reverses the effects of an identified deployment by restoring the affected deployment subject to its identified predeployment state.

A Deployment Rollback may apply to:

• Infrastructure Resources
• Virtual Machines
• Kubernetes Clusters
• Containerized Workloads
• Platform Services
• Relationships among deployed subjects
• A resulting Infrastructure Environment

The predeployment state may be identified through:

• A deployment record
• A prior Baseline
• A prior Revision
• A prior Infrastructure Configuration
• A prior Image
• A checkpoint
• Another recorded valid state

Deployment Rollback differs from deployment cancellation:

• Deployment cancellation stops a deployment before completion
• Deployment Rollback reverses the effects already produced by a deployment

Deployment Rollback differs from deployment retry:

• Deployment Rollback restores the predeployment state
• Deployment retry performs the deployment operation again

Deployment Rollback may precede a corrected deployment or another recovery operation.

Deployment Rollback does not imply that every deployment effect can be reversed.

Applicable requirements should identify:

• The deployment subject
• The deployment is being reversed
• The predeployment state
• The rollback initiation condition
• The effects included in the rollback
• Effects excluded from the rollback
• The required rollback result
• The generated Evidence

A Deployment Rollback may require separate handling for:

• Persistent data
• External services
• Credentials
• Messages
• Transactions
• Provider-managed resources
• Changes performed outside the deployment boundary

A deployment replaces a Containerized Workload with an unacceptable Revision. Crucible performs Deployment Rollback by removing the new workload Revision and restoring the workload configuration and Image used immediately before the deployment.
