Overview ¶
Package template provides reusable workload blueprints. A Template captures the spec needed to instantiate a Workload — image, resources, env, secrets references, config files, volumes, ports, health check, labels and annotations — without any runtime state. Templates are authored directly via the template Service or forked from an existing Workload via CreateFromWorkload.
Templates are tenant-scoped. The persistent schema lives in store/<backend>/template.go and is owned by this package — deploy no longer participates in template storage.

Functions ¶
func NewService ¶
NewService wires the template service. The WorkloadSpecReader is optional at construction time — call SetWorkloadReader once the workload service is built to enable CreateFromWorkload. Returns a concrete *service so the caller can use both Service methods and SetWorkloadReader.
The event bus is also optional — pass nil and template lifecycle events will be silently dropped. The default app wiring always passes the shared bus so events flow into the audit hook.
Types ¶
type ConfigFile ¶
type ConfigFile = provider.ConfigFile
ConfigFile is an alias for provider.ConfigFile. See SecretRef for the rationale.
type CreateFromWorkloadRequest ¶
type CreateFromWorkloadRequest struct {
Name string `json:"name" validate:"required"`
Description string `json:"description,omitempty"`
Notes string `json:"notes,omitempty"`
}
CreateFromWorkloadRequest forks a template from an existing workload's spec. Only Name and Description are user-supplied — every other field is read from the workload via the WorkloadSpecReader.
type CreateRequest ¶
type CreateRequest struct {
Name string `json:"name" validate:"required"`
Description string `json:"description,omitempty"`
DefaultKind provider.WorkloadKind `json:"default_kind,omitempty"`
DefaultStrategy string `json:"default_strategy,omitempty"`
Services []provider.ServiceSpec `json:"services" validate:"required,min=1"`
Labels map[string]string `json:"labels,omitempty"`
Notes string `json:"notes,omitempty"`
}
CreateRequest holds the parameters for creating a workload template.
type ListOptions ¶
type ListOptions struct {
Cursor string `json:"cursor,omitempty"`
Limit int `json:"limit,omitempty"`
}
ListOptions configures template listing.
type ListResult ¶
type ListResult struct {
Items []*Template `json:"items"`
NextCursor string `json:"next_cursor,omitempty"`
Total int `json:"total"`
}
ListResult holds a page of templates with a total count.
type SecretRef ¶
SecretRef is an alias for provider.SecretRef. The canonical type lives in the provider package so it can sit alongside ServiceSpec without introducing a template ↔ provider import cycle. Kept here as a thin alias so existing callers that referenced template.SecretRef do not need to chase the rename.
type Service ¶
type Service interface {
// Create persists a new template authored from raw fields.
Create(ctx context.Context, req CreateRequest) (*Template, error)
// CreateFromWorkload forks a new template from an existing
// workload's current spec. The workload's image, env, secrets,
// config files, volumes, ports, health check, labels and
// annotations are copied wholesale into the template.
CreateFromWorkload(ctx context.Context, workloadID id.ID, req CreateFromWorkloadRequest) (*Template, error)
// Get returns a specific template.
Get(ctx context.Context, templateID id.ID) (*Template, error)
// Update mutates an existing template; nil request fields are left untouched.
Update(ctx context.Context, templateID id.ID, req UpdateRequest) (*Template, error)
// Delete removes a template.
Delete(ctx context.Context, templateID id.ID) error
// List returns templates for the caller's tenant.
List(ctx context.Context, opts ListOptions) (*ListResult, error)
}
Service manages workload templates. It supports authoring templates directly, listing/reading/updating/deleting them, and forking a new template from an existing workload's spec.
type Store ¶
type Store interface {
InsertTemplate(ctx context.Context, t *Template) error
GetTemplate(ctx context.Context, tenantID string, templateID id.ID) (*Template, error)
UpdateTemplate(ctx context.Context, t *Template) error
DeleteTemplate(ctx context.Context, tenantID string, templateID id.ID) error
ListTemplates(ctx context.Context, tenantID string, opts ListOptions) (*ListResult, error)
}
Store is the persistence interface for workload templates. Method names are entity-suffixed so a single concrete store type can implement Template + Workload + Instance + Deploy + Network etc. without method-name collisions on Insert/Get/List/Update/Delete.
type Template ¶
type Template struct {
ctrlplane.Entity
TenantID string `db:"tenant_id" json:"tenant_id"`
Name string `db:"name" json:"name"`
Description string `db:"description" json:"description,omitempty"`
DefaultKind provider.WorkloadKind `db:"default_kind" json:"default_kind,omitempty"`
DefaultStrategy string `db:"default_strategy" json:"default_strategy,omitempty"`
Services []provider.ServiceSpec `db:"services" json:"services"`
Labels map[string]string `db:"labels" json:"labels,omitempty"`
Notes string `db:"notes" json:"notes,omitempty"`
}
Template is a reusable workload blueprint that can be instantiated to create a Workload. The Services slice mirrors a Workload's Services — instantiation copies them onto the new Workload verbatim. Workload- level fields (DefaultKind, DefaultStrategy, Labels) seed the workload at creation time and may be overridden by the CreateRequest.
func (*Template) MainService ¶
func (t *Template) MainService() *provider.ServiceSpec
MainService returns the template's Main service, or nil when none is configured. Used by the dashboard to show "the template's image" when a single representative is needed.
type UpdateRequest ¶
type UpdateRequest struct {
Name *string `json:"name,omitempty"`
Description *string `json:"description,omitempty"`
DefaultKind *provider.WorkloadKind `json:"default_kind,omitempty"`
DefaultStrategy *string `json:"default_strategy,omitempty"`
Services []provider.ServiceSpec `json:"services,omitempty"`
Labels map[string]string `json:"labels,omitempty"`
Notes *string `json:"notes,omitempty"`
}
UpdateRequest holds the parameters for updating a workload template. Pointer fields enable partial updates — only non-nil fields are applied.
type WorkloadSpec ¶
type WorkloadSpec struct {
Kind provider.WorkloadKind
Services []provider.ServiceSpec
Labels map[string]string
}
WorkloadSpec is the projection of a Workload's blueprint-relevant fields the template service needs in order to fork a template from a workload. The workload package adapts its concrete Workload onto this shape via WorkloadSpecReader so this package never imports workload.
type WorkloadSpecReader ¶
type WorkloadSpecReader interface {
ReadWorkloadSpec(ctx context.Context, tenantID string, workloadID id.ID) (*WorkloadSpec, error)
}
WorkloadSpecReader is the dependency template uses to read a workload's spec when forking a template.
