How It Works
- Ctrlplane renders an ArgoCD Application from your template
- The Application is created or updated via ArgoCD API
- ArgoCD syncs the application to Kubernetes
- Ctrlplane verifies the application reaches
Healthy+Syncedstatus - Job is marked successful when verification passes
Prerequisites
- ArgoCD server with API access
- API token with application create/update permissions
- Network connectivity from Ctrlplane to ArgoCD
Configuration
Job Agent Setup
Create a job agent with typeargo-cd:
Deployment Configuration
| Field | Required | Description |
|---|---|---|
serverUrl | Yes | ArgoCD server URL (host:port) |
apiKey | Yes | ArgoCD API token |
template | Yes | Go template for ArgoCD Application |
Template Context
The template has access to all job context. Variables are accessed using Go template syntax:{{.variable.property}}. The job context is derived from the resources
returned by the deployment selector (and narrowed by the environment selector),
so the data available to the template reflects that specific target.
Top-Level Variables
| Variable | Description |
|---|---|
.job | Current job details |
.version | Version being deployed (shortcut) |
.deployment | User-defined deployment configuration and properties |
.environment | User-defined environment you deploy into and its properties |
.resource | User-defined resource you deploy against and its properties |
.variables | Merged deployment variables (key-value strings) |
Resource Properties
Each job invocation is tied to a specific resource instance returned by your selector, so the.resource values can differ for every ArgoCD
template invocation.
| Property | Type | Description |
|---|---|---|
.resource.id | string | Unique resource ID |
.resource.name | string | Display name |
.resource.identifier | string | Unique identifier within workspace |
.resource.kind | string | Resource kind (e.g., KubernetesCluster) |
.resource.version | string | Resource schema version |
.resource.config | object | Arbitrary configuration data |
.resource.metadata | map[string]string | Key-value metadata labels |
.resource.workspaceId | string | Parent workspace ID |
.resource.providerId | string | Resource provider ID (if any) |
.resource.createdAt | timestamp | Creation timestamp |
.resource.updatedAt | timestamp | Last update timestamp |
.resource.lockedAt | timestamp | Lock timestamp (if locked) |
Deployment Properties
Each job invocation is tied to a specific deployment, so.deployment values can differ
for every ArgoCD template invocation.
| Property | Type | Description |
|---|---|---|
.deployment.id | string | Unique deployment ID |
.deployment.name | string | Display name |
.deployment.slug | string | URL-friendly identifier |
.deployment.description | string | Optional description |
.deployment.systemId | string | Parent system ID |
.deployment.jobAgentId | string | Associated job agent ID |
.deployment.jobAgentConfig | object | Job agent configuration |
.deployment.resourceSelector | object | Resource selector for targeting |
Environment Properties
Each job invocation is tied to a specific environment, so.environment values can differ
for every ArgoCD template invocation.
| Property | Type | Description |
|---|---|---|
.environment.id | string | Unique environment ID |
.environment.name | string | Display name |
.environment.description | string | Optional description |
.environment.systemId | string | Parent system ID |
.environment.resourceSelector | object | Resource selector |
.environment.createdAt | timestamp | Creation timestamp |
Version Properties
Access via.version:
| Property | Type | Description |
|---|---|---|
.version.id | string | Unique version ID |
.version.tag | string | Version tag (e.g., v1.2.3) |
.version.name | string | Display name |
.version.message | string | Optional commit/release message |
.version.status | string | Version status |
.version.config | object | Version-specific configuration |
.version.metadata | map[string]string | Version metadata |
.version.jobAgentConfig | object | Version-level job agent config |
.version.deploymentId | string | Parent deployment ID |
.version.createdAt | timestamp | Creation timestamp |
Job Properties
| Property | Type | Description |
|---|---|---|
.job.id | string | Unique job ID |
.job.status | string | Current status |
.job.message | string | Status message |
.job.externalId | string | External system reference |
.job.metadata | map[string]string | Job metadata |
.job.jobAgentId | string | Executing job agent ID |
.job.releaseId | string | Associated release ID |
.job.createdAt | timestamp | Creation timestamp |
.job.startedAt | timestamp | Execution start timestamp |
.job.completedAt | timestamp | Completion timestamp |
.job.updatedAt | timestamp | Last update timestamp |
Variables
The.variables map contains all resolved deployment variables as strings:
Accessing Nested Config
Resource and version configs are arbitrary objects. Access nested properties:Template Functions
The template supports Sprig functions:Automatic Verification
When an ArgoCD Application is created, Ctrlplane automatically starts a verification that checks:- Application sync status is
Synced - Application health status is
HealthyorProgressing
Example: Multi-Environment Setup
Example: Kustomize Overlay
Troubleshooting
Application not syncing
- Check ArgoCD server logs
- Verify the repository is accessible from ArgoCD
- Check the target revision exists
Authentication errors
- Verify the API token is valid
- Check token has correct permissions
- Ensure
serverUrlincludes the correct port
Verification failing
- Check ArgoCD Application status in the UI
- Review sync errors in ArgoCD
- Verify destination cluster is accessible
