| # Understanding Deployments in Ctrlplane | ||
|
|
||
| # Deployments | ||
| Deployments in Ctrlplane are the central organizing principle for managing and | ||
| orchestrating the release of your software or infrastructure across various | ||
| environments within a system. A deployment represents a complete, end-to-end process | ||
| for delivering changes to your system, encompassing everything from the initial | ||
| code commit to the final production release. | ||
|
|
||
| Deployments are the core component of Ctrlplane, orchestrating the delivery of | ||
| your applications across various environments and targets. They encapsulate the | ||
| configuration, workflows, and triggers required to automate and manage the | ||
| entire release lifecycle. | ||
| ## What is a Deployment? | ||
|
|
||
| ## Key Components | ||
| A deployment in Ctrlplane is: | ||
|
|
||
| A Ctrlplane deployment consists of: | ||
| 1. **A Logical Unit**: It typically represents a single service, application, or | ||
| piece of infrastructure. | ||
|
|
||
| - **System:** High-level categorization (e.g., "Microservices," "Data Pipeline") | ||
| - **Release:** Specific version or build to be deployed | ||
| - **Environments:** Deployment stages (e.g., "Dev," "Staging," "Prod") | ||
| - **Targets:** Deployment destinations (e.g., K8s clusters, VM groups, FaaS) | ||
| - **Workflows:** Automated tasks executed during deployment | ||
| - **Job Agents:** Integrations triggering external CI/CD pipelines | ||
| - **Policies (Optional):** Rules governing the deployment process | ||
| 2. **System-Bound**: Each deployment is assigned to a specific system, which contains | ||
| multiple environments (e.g., QA, Staging, Production). When you create a deployment, | ||
| it automatically becomes part of all environments within that system. | ||
|
|
||
| ## Deployment Process | ||
| 3. **Version Control**: It manages multiple releases (versions) of your software | ||
| or infrastructure configuration. | ||
|
|
||
| 1. **Release Creation:** Initiate a new release with version/build number | ||
| 2. **Workflow Triggering:** Automatic activation of environment-specific workflows | ||
| 3. **Job Agent Activation:** Triggers sent to external CI/CD systems | ||
| 4. **Pipeline Execution:** External systems deploy to specified targets | ||
| 5. **Status Tracking:** Real-time monitoring of deployment progress | ||
| 4. **Pipeline Definition**: It includes a defined CI/CD pipeline that outlines | ||
| the steps for building, testing, and deploying your changes. | ||
|
|
||
| <Callout type="info"> | ||
| Best practice: Use a single deployment with a pipeline supporting multiple | ||
| targets, rather than separate deployments for each target. | ||
| </Callout> | ||
| 5. **Release Manager**: It groups and organizes releases, providing a historical | ||
| view of all deployments. | ||
|
|
||
| ## Key Benefits | ||
| ## Key Components of a Deployment | ||
|
|
||
| - **Automation:** Minimizes manual intervention and error potential | ||
| - **Flexibility:** Supports various deployment strategies and complexities | ||
| - **Integration:** Seamless connection with existing CI/CD toolchains | ||
| - **Visibility:** Real-time deployment status and progress tracking | ||
| - **Control:** Policy enforcement and approval workflows | ||
| A deployment in Ctrlplane typically includes: | ||
|
|
||
| ## Example: Microservices Deployment | ||
| 1. **Releases**: Individual versions of your software or infrastructure | ||
| configuration. | ||
|
|
||
| Consider a microservices architecture with environments (Dev, Staging, Prod) and | ||
| multiple regional Kubernetes clusters. Configure a Ctrlplane deployment with: | ||
| 2. **CI/CD Pipeline**: The defined process for deploying releases. | ||
|
|
||
| 1. System: "Microservices Platform" | ||
| 2. Environments: Dev, Staging, Prod | ||
| 3. Targets: Regional K8s clusters | ||
| 4. Job Agents: Configured for GitLab CI/CD | ||
| 5. Policies: Require approvals for Staging and Prod | ||
| 3. **System and Environment Association**: The deployment is part of all | ||
| environments within its assigned system, allowing for consistent deployment | ||
| across different stages. | ||
|
|
||
| When creating a release, Ctrlplane orchestrates: | ||
| 4. **Job Configurations**: Specifications for the jobs that will be created and | ||
| run for each release and target. | ||
|
|
||
| 1. Dev deployment via GitLab CI/CD | ||
| 2. Staging deployment after approval | ||
| 3. Production rollout across regions | ||
| 5. **Variables**: Target-specific variables that allow the same pipeline to | ||
| be used across different environments. | ||
|
|
||
| ## Key Takeaways | ||
| ## Systems, Environments, and Target Filtering | ||
|
|
||
| - Deployments centralize release management across diverse environments and | ||
| systems | ||
| - Ctrlplane complements existing CI/CD tools, providing higher-level | ||
| orchestration | ||
| - Achieve streamlined, efficient, and reliable deployment processes at scale | ||
| Ctrlplane uses a hierarchical structure to manage deployments: | ||
|
|
||
| 1. **Systems**: The top-level organizational unit. A system contains multiple | ||
| environments and is associated with one or more deployments. | ||
|
|
||
| 2. **Environments**: Subsets of a system (e.g., QA, Staging, Production). Each | ||
| environment can be configured with specific settings and policies. | ||
|
|
||
| 3. **Environment Configuration**: Each environment is configured with label | ||
| filters to determine which targets fall under that environment. This allows | ||
| for fine-grained control over where deployments are applied. | ||
|
|
||
| 4. **Target Filtering**: When a release is created, Ctrlplane uses the | ||
| environment's label filters to identify matching targets. It then runs the | ||
| appropriate jobs for each of these targets. | ||
|
|
||
| 5. **Inter-Environment Policies**: Environments are connected by policies that | ||
| determine when and how jobs should run. These policies control the | ||
| progression of deployments through environments (e.g., from Staging to | ||
| Production). | ||
|
|
||
| ## Deployment Workflow | ||
|
|
||
| 1. **Deployment Creation**: A deployment is created and assigned to a system. | ||
|
|
||
| 2. **Release Initiation**: A new release is created within the deployment. | ||
|
|
||
| 3. **Environment Processing**: For each environment in the system: | ||
|
|
||
| - The environment's label filters are applied to identify relevant targets. | ||
| - Jobs are created for each matching target based on the deployment's job | ||
| definitions. | ||
|
|
||
| 4. **Policy Enforcement**: Inter-environment policies determine when jobs can | ||
| run, allowing for controlled progression through environments. | ||
|
|
||
| 5. **Job Execution**: Jobs are executed on the identified targets, applying the | ||
| release changes. | ||
|
|
||
| ## Creating and Managing Deployments | ||
|
|
||
| Deployments can be created and managed in two primary ways: | ||
|
|
||
| 1. **Manual Creation**: Through the Ctrlplane UI or API, specifying the system | ||
| it belongs to. | ||
|
|
||
| 2. **Automated Creation**: By including a `.ctrlplane.yaml` file in your Git | ||
| repository. This method allows for automatic deployment creation when new | ||
| repositories are added, with system assignment specified in the configuration. | ||
|
|
||
| Example `.ctrlplane.yaml`: |

| # Systems | ||
|
|
||
| In Ctrlplane, a system is a high-level abstraction for organizing and managing | ||
| related deployments. It's designed to streamline your CI/CD pipelines and | ||
| enforce consistency across your infrastructure. | ||
|
|
||
| ## Key Concepts | ||
|
|
||
| - **Logical Grouping:** Systems categorize deployments based on shared | ||
| attributes or purposes. | ||
| - **Environment Standardization:** All deployments within a system use the same | ||
| set of environments (e.g., Dev, QA, Staging, Production). | ||
| - **Policy Enforcement:** Systems apply uniform environment policies across all | ||
| associated deployments. | ||
|
|
||
| ## Benefits for DevOps | ||
|
|
||
| 1. **Scalable Management:** Centralize environment and policy configurations at | ||
| the system level, reducing overhead when managing multiple deployments. | ||
| 2. **Consistent Workflows:** Ensure standardized deployment processes across | ||
| related projects. | ||
| 3. **Simplified Governance:** Implement and enforce policies uniformly across | ||
| all deployments within a system. | ||
| 4. **Efficient Onboarding:** Quickly set up new deployments with pre-configured | ||
| environments and policies. | ||
|
|
||
| ## Implementation | ||
|
|
||
| 1. **System Creation:** Define a system with its required environments (e.g., | ||
| Dev, QA, Staging, Production). | ||
| 2. **Policy Configuration:** Set up environment policies at the system level | ||
| (e.g., approval processes, security checks, deployment windows). | ||
| 3. **Deployment Association:** Link deployments to the appropriate system, | ||
| automatically inheriting its environments and policies. | ||
| Systems in Ctrlplane are the highest level of organizational units, designed to | ||
| group related deployments and environments together. They provide a structured | ||
| approach to managing complex deployment pipelines and enforcing consistency | ||
| across your infrastructure. | ||
|
|
||
| ## Key Features of Systems | ||
|
|
||
| - **Deployment Organization:** Systems contain information about all associated | ||
| deployments, allowing for centralized management. | ||
| - **Environment Standardization:** All deployments within a system share the | ||
| same set of environments, ensuring consistency across the deployment pipeline. | ||
| - **Scalability:** Systems can accommodate as many deployments and environments | ||
| as needed, supporting growth and complexity in your infrastructure. | ||
| - **Deployment Cycle Alignment:** Commonly used to group applications with | ||
| similar deployment cycles, facilitating coordinated releases. | ||
| - **Access Control:** Systems provide a natural boundary for implementing | ||
| role-based access control (RBAC) policies. | ||
|
|
||
| ## System Structure | ||
|
|
||
| 1. **Deployments:** Each system can contain multiple deployments, representing | ||
| different applications or services. | ||
| 2. **Environments:** Systems define a set of environments (e.g., Development, | ||
| QA, Staging, Production) that are shared across all associated deployments. | ||
| 3. **Policies:** System-level policies can be applied to govern deployment | ||
| processes across all included deployments and environments. | ||
| 4. **Configurations:** Shared configurations can be defined at the system level | ||
| and inherited by deployments. | ||
|
|
||
| ## Benefits of Using Systems | ||
|
|
||
| - **Consistency:** Enforce uniform environments and deployment processes across | ||
| related projects. | ||
| - **Simplified Management:** Centralize configuration and policy management at | ||
| the system level. | ||
| - **Efficient Onboarding:** Quickly set up new deployments with pre-configured | ||
| environments and policies. | ||
| - **Coordinated Releases:** Facilitate synchronized deployments for applications | ||
| with interdependencies. | ||
| - **Improved Visibility:** Gain a holistic view of related deployments and their | ||
| statuses. | ||
| - **Streamlined Governance:** Apply security and compliance policies | ||
| consistently across all deployments within a system. | ||
|
|
||
| ## Best Practices | ||
|
|
||
| - Group deployments logically based on application, team, or business function. | ||
| - Regularly review and update system-level policies to maintain security and | ||
| compliance. | ||
| - Use systems to enforce standardization across your organization's deployment | ||
| processes. | ||
| - Leverage system-level configurations to implement infrastructure-as-code | ||
| principles for your CI/CD pipelines. | ||
|
|
||
| ## Integration Points | ||
|
|
||
| - CI/CD Tools: Systems can be integrated with popular CI/CD tools to enforce | ||
| policies and standardize deployment workflows. | ||
| - Infrastructure-as-Code: Use Ctrlplane's API or CLI to programmatically manage | ||
| systems and their configurations. | ||
| - Monitoring and Logging: Implement consistent monitoring and logging practices | ||
| across all deployments within a system. | ||
|
|
||
| By leveraging Ctrlplane's systems, DevOps engineers can achieve greater | ||
| consistency, scalability, and control over their deployment processes. | ||
| 1. **Logical Grouping:** Create systems based on application domains, teams, or | ||
| deployment cycles. | ||
| 2. **Standardized Environments:** Define a consistent set of environments that | ||
| make sense for your development and release processes. | ||
| 3. **Policy Enforcement:** Implement system-wide policies to ensure compliance | ||
| and security across all deployments. | ||
| 4. **Regular Review:** Periodically assess and update system configurations to | ||
| align with evolving organizational needs. | ||
|
|
||
| ## Example Use Case | ||
|
|
||
| A typical use of systems might involve grouping all microservices for a | ||
| particular product: | ||
|
|
||
| - **System:** "E-commerce Platform" | ||
| - **Environments: **Dev, QA, Staging, Production | ||
| - **Deployments:** | ||
| - User Authentication Service | ||
| - Product Catalog Service | ||
| - Order Processing Service | ||
| - Payment Gateway Service | ||
| - **Shared Configurations:** | ||
| - Database connection strings | ||
| - API gateway settings | ||
| - **System-wide Policies:** | ||
| - Automated rollback on failed deployments | ||
| - Required approvals for production deployments | ||
|
|
||
| By organizing these services under one system, you ensure they all progress | ||
| through the same environments and adhere to consistent deployment policies, | ||
| facilitating a coordinated release process for the entire e-commerce platform. |
