Functions

func ApplicationBackendNetworkName 

func ApplicationBackendNetworkName(m Manifest) string

ApplicationBackendNetworkName returns the stable Docker/Podman network name used by BaseHarbor-managed backend services for one application environment.

Application-owned workloads may attach to this network as an additional external network without replacing their own Compose networks. The current Compose provider maps the logical backend network to the deterministic project default network.

func ApplicationExposureNetworkName added in v0.4.4 

func ApplicationExposureNetworkName(m Manifest) string

ApplicationExposureNetworkName returns the stable Compose network used to connect explicitly exposed workload endpoints to the selected exposure provider. It is separate from the managed backend network because endpoint exposure must also work for workload-only applications.

func CapabilityBindings added in v0.4.1 

func CapabilityBindings(m Manifest) ([]capability.Binding, error)

func CheckControlPlaneDestroySafe added in v0.4.4 

func CheckControlPlaneDestroySafe() error

func CheckManagedRuntimeDefinition 

func CheckManagedRuntimeDefinition(files RuntimeFiles, m Manifest) error

CheckManagedRuntimeDefinition prevents destructive operations from trusting a locally modified Compose file. BaseHarbor may only mutate the runtime shape it originally generated and understands for the current manifest.

func CheckReferenceProviderRegistry added in v0.4.4 

func CheckReferenceProviderRegistry(m Manifest) error

CheckReferenceProviderRegistry validates the protected provider registry and simulates the desired application reconciliation without writing it. Lifecycle callers use this during preflight so invalid provider metadata fails before any runtime or workload mutation.

func CheckRuntimePermissions 

func CheckRuntimePermissions(files RuntimeFiles) error

func CheckSupportedRuntimeServices 

func CheckSupportedRuntimeServices(m Manifest) error

func ConfiguredRuntimeAPIURL 

func ConfiguredRuntimeAPIURL() (string, bool, error)

func EnsureRuntimeIdentity 

func EnsureRuntimeIdentity(m Manifest, files RuntimeFiles) (string, error)

func ExpectedPersistentRuntimeResources 

func ExpectedPersistentRuntimeResources(m Manifest) []bhruntime.ProjectResource

func ExpectedPostgresRuntimeResources 

func ExpectedPostgresRuntimeResources(m Manifest) []bhruntime.ProjectResource

ExpectedPostgresRuntimeResources is kept for compatibility with the first runtime milestone. New lifecycle code should use ExpectedRuntimeResources.

func ExpectedRuntimeResources 

func ExpectedRuntimeResources(m Manifest) []bhruntime.ProjectResource

func FindRepositoryManifest 

func FindRepositoryManifest(start string) (string, error)

FindRepositoryManifest returns the nearest baseharbor.yaml from start upward. This lets developers run baha from nested directories inside an application repository.

func GenerateSecretValue 

func GenerateSecretValue(generation SecretGeneration) ([]byte, error)

func HasExplicitWorkload added in v0.3.0 

func HasExplicitWorkload(m Manifest) bool

HasExplicitWorkload reports whether the repository manifest explicitly declares a Compose workload. Workload-only applications must be explicit so validation never guesses based on files outside the manifest.

func HasManagedRuntimeServices added in v0.3.0 

func HasManagedRuntimeServices(m Manifest) bool

HasManagedRuntimeServices reports whether BaseHarbor owns a materialized PostgreSQL or Valkey runtime for the application. Managed secrets currently require one of those services and therefore do not form a standalone runtime.

func HasRequiredFileSecrets 

func HasRequiredFileSecrets(m Manifest) bool

func InspectOwnedRuntimeResources 

func InspectOwnedRuntimeResources(ctx context.Context, compose bhruntime.Compose, m Manifest) ([]bhruntime.ProjectResource, error)

func ManagedSecretsSecureBinding added in v0.4.5 

func ManagedSecretsSecureBinding(m Manifest) capability.SecureBinding

ManagedSecretsSecureBinding describes the existing BaseHarbor runtime identity/secret-delivery semantics without exposing OpenBao paths, AppRoles, policies, tokens, private keys, or provider-specific object names.

func MaterializeRuntimeIdentityWorkloadOverride 

func MaterializeRuntimeIdentityWorkloadOverride(m Manifest, workload WorkloadFiles, files RuntimeFiles, plan WorkloadBindingPlan) (string, bool, error)

MaterializeRuntimeIdentityWorkloadOverride adds only the protected bindings that selected application services actually consume. Runtime identity is injected through ordinary environment file paths plus Compose secret mounts; applications do not configure certificates, keys or broker topology.

func PostgresInstanceNames 

func PostgresInstanceNames(m Manifest) []string

func ReallocateRuntimePorts 

func ReallocateRuntimePorts(m Manifest, files RuntimeFiles) error

ReallocateRuntimePorts replaces only the generated host-port assignments for an already materialized application runtime. Credentials, databases, volumes and other persisted runtime values are left unchanged. This is used when the container runtime proves that a probed loopback port was claimed between allocation and the actual container bind.

func ReconcileReferenceProviderRegistry added in v0.4.2 

func ReconcileReferenceProviderRegistry(m Manifest) error

func RedisInstanceNames 

func RedisInstanceNames(m Manifest) []string

func ReleaseApplicationProviderRegistry added in v0.4.2 

func ReleaseApplicationProviderRegistry(m Manifest) error

func RequiredSecretNames 

func RequiredSecretNames(m Manifest) []string

func RequiredSecretUsesFileBinding 

func RequiredSecretUsesFileBinding(name string) bool

func ResolveCapabilityResources added in v0.4.1 

func ResolveCapabilityResources(contract PortableContract) ([]capability.Resource, error)

func ResolveWorkloadCompose 

func ResolveWorkloadCompose(repositoryRoot string, m Manifest) (string, bool, error)

func ResourceExists

func SecretFileContainerPath(name string) string

func SecretFileHostDir 

func SecretFileHostDir(files RuntimeFiles) string

func SecretFileHostPath 

func SecretFileHostPath(files RuntimeFiles, name string) string

func ValidatePostgresBackupSet 

func ValidatePostgresBackupSet(m Manifest, backups []PostgresBackup) error

func VerifyPostgresRuntime 

func VerifyPostgresRuntime(ctx context.Context, compose bhruntime.Compose, m Manifest, files RuntimeFiles) error

func VerifyValkeyRuntime

Types

type Action 

type Action struct {
	Kind        string
	Resource    string
	Description string
}

type BackupMetadata added in v0.3.0 

type BackupMetadata struct {
	Version           int       `json:"version"`
	Application       string    `json:"application"`
	Environment       string    `json:"environment"`
	CreatedAt         time.Time `json:"created_at"`
	ArchivePath       string    `json:"archive_path"`
	PostgresResources []string  `json:"postgres_resources,omitempty"`
	IncludesSecrets   bool      `json:"includes_secrets"`
}

func (BackupMetadata) Validate added in v0.3.0 

func (m BackupMetadata) Validate() error

type CapabilityKind added in v0.4.0 

type CapabilityKind = capability.Kind

CapabilityKind and CapabilityRequirement remain aliases in the application package so existing v0.4 callers keep their source-compatible contract while the reusable capability domain moves into the shared core. 

const (
	CapabilitySQL          CapabilityKind = capability.SQL
	CapabilityKeyValue     CapabilityKind = capability.KeyValue
	CapabilityExposureHTTP CapabilityKind = capability.ExposureHTTP
)

type CapabilityRequirement added in v0.4.0 

type CapabilityRequirement = capability.Requirement

type HTTPExposureRequirement added in v0.4.4 

type HTTPExposureRequirement struct {
	Name       string
	Service    string
	Port       int
	Protocol   string
	Visibility string
}

HTTPExposureRequirement is provider-neutral public HTTP exposure intent. Hostname, host port, TLS source paths and reverse-proxy implementation are deployment/provider state and deliberately absent.

type Manifest 

type Manifest struct {
	Version     int
	Name        string
	Environment string
	Services    Services
	Secrets     SecretRequirements
	Workload    WorkloadConfig
	Exposures   []HTTPExposureRequirement
}

Manifest is the declarative application backend request understood by BaseHarbor.

func LoadManifestFile 

func LoadManifestFile(path string) (Manifest, error)

func New 

func New(name, environment string, postgres, redis, secrets bool) Manifest

func ParseYAML 

func ParseYAML(input string) (Manifest, error)

ParseYAML parses the intentionally small v1 manifest grammar without adding a runtime dependency.

func WithGeneratedSecret 

func WithGeneratedSecret(m Manifest, name, generationType string, size int) Manifest

func WithHTTPExposure added in v0.4.4 

func WithHTTPExposure(m Manifest, name, service string, port int, protocol string) Manifest

func WithPostgresInstances 

func WithPostgresInstances(m Manifest, names ...string) Manifest

func WithRedisInstances 

func WithRedisInstances(m Manifest, names ...string) Manifest

func WithRequiredSecrets 

func WithRequiredSecrets(m Manifest, names ...string) Manifest

func WithWorkload 

func WithWorkload(m Manifest, compose string, services ...string) Manifest

func (Manifest) Validate 

func (m Manifest) Validate() error

func (Manifest) YAML 

func (m Manifest) YAML() string

type Plan 

type Plan struct {
	Application string
	Environment string
	Actions     []Action
}

func BuildPlan 

func BuildPlan(m Manifest) (Plan, error)

type PortableContract added in v0.4.0 

type PortableContract struct {
	Application  string
	Capabilities []CapabilityRequirement
	Secrets      SecretContract
	Exposures    []HTTPExposureRequirement
}

PortableContract is the provider-neutral application requirement view used as the seam between manifest compatibility and runtime/capability providers.

Deployment context such as environment, Compose paths, host ports, TLS source directories and provider object names must not be added here. Those belong to deployment state or provider-specific configuration.

func PortableContractFromManifest added in v0.4.0 

func PortableContractFromManifest(m Manifest) (PortableContract, error)

PortableContractFromManifest translates the current manifest v1 compatibility surface into provider-neutral requirements without changing manifest behavior. The translation is deliberately one-way for now: v0.4 can evolve a future contract schema while existing v0.3 manifests continue to load unchanged.

type PostgresBackup 

type PostgresBackup struct {
	Instance string
	SQL      []byte
}

func DumpPostgresInstances 

func DumpPostgresInstances(ctx context.Context, runtime PostgresBackupRuntime, m Manifest, files RuntimeFiles) ([]PostgresBackup, error)

type PostgresBackupRuntime 

type PostgresBackupRuntime interface {
	ExecProject(ctx context.Context, project, composeFile, envFile, service string, args ...string) (string, error)
	ExecProjectInput(ctx context.Context, project, composeFile, envFile string, input []byte, service string, args ...string) (string, error)
}

type RecoveryMetadata added in v0.3.0 

type RecoveryMetadata struct {
	Version         int       `json:"version"`
	Application     string    `json:"application"`
	Environment     string    `json:"environment"`
	RestoredAt      time.Time `json:"restored_at"`
	BackupCreatedAt time.Time `json:"backup_created_at"`
	ArchivePath     string    `json:"archive_path"`
}

func (RecoveryMetadata) Validate added in v0.3.0 

func (m RecoveryMetadata) Validate() error

type RuntimeContract 

type RuntimeContract struct {
	Env         string
	BindingsDir string
	Metadata    string
}

func EnsureRuntimeContract 

func EnsureRuntimeContract(m Manifest, files RuntimeFiles) (RuntimeContract, error)

type RuntimeFiles 

type RuntimeFiles struct {
	Dir            string
	Compose        string
	Env            string
	ApplicationEnv string
	Bindings       string
}

func EnsurePostgresRuntime 

func EnsurePostgresRuntime(store Store, m Manifest) (RuntimeFiles, error)

EnsurePostgresRuntime is kept for callers from the first runtime milestone.

func EnsureRuntime 

func EnsureRuntime(store Store, m Manifest) (RuntimeFiles, error)

func ExistingRuntimeFiles 

func ExistingRuntimeFiles(store Store, m Manifest) (RuntimeFiles, error)

func RuntimeFilesFor added in v0.4.4 

func RuntimeFilesFor(store Store, m Manifest) RuntimeFiles

type SecretContract added in v0.4.0 

type SecretContract struct {
	Managed  bool
	Required []SecretRequirement
}

SecretContract describes secret intent without selecting a concrete secret backend or delivery mechanism. Required values remain names/generation intent only; provider credentials and provider object identifiers never belong here.

type SecretGeneration 

type SecretGeneration struct {
	Type   string
	Length int
	Bytes  int
}

type SecretRequirement 

type SecretRequirement struct {
	Name     string
	Generate *SecretGeneration
}

func GeneratedSecretRequirements 

func GeneratedSecretRequirements(m Manifest) []SecretRequirement

func SecretRequirementByName 

func SecretRequirementByName(m Manifest, name string) (SecretRequirement, bool)

type SecretRequirements 

type SecretRequirements struct {
	Required []SecretRequirement
}

SecretRequirements declares application-owned secret requirements. Values never belong in the manifest. Generate only expresses explicit intent for BaseHarbor to create a missing value directly in the managed secret backend.

type ServiceBinding added in v0.3.0 

type ServiceBinding struct {
	Kind     string
	Instance string
	Host     string
	Port     string
	Database string
	Username string
	Password string
	URI      string
}

ServiceBinding is the provider-neutral information needed by developer access actions. Callers should prefer these fields over runtime/container names so a later provider can satisfy the same action model.

func ResolveServiceBinding added in v0.3.0 

func ResolveServiceBinding(files RuntimeFiles, kind, instance string) (ServiceBinding, error)

ResolveServiceBinding loads an already-materialized owner-only service binding. It never creates or rotates credentials.

type ServiceInstance 

type ServiceInstance struct{}

ServiceInstance is the stable logical identity of one requested backend service. The empty v1 shape is intentional: topology remains a BaseHarbor implementation detail and future intent such as availability can evolve here.

type Services 

type Services struct {
	Postgres          bool
	Redis             bool
	Secrets           bool
	PostgresInstances map[string]ServiceInstance
	RedisInstances    map[string]ServiceInstance
}

type Store 

type Store struct {
	Root string
}

func DefaultStore 

func DefaultStore() Store

func (Store) Create 

func (s Store) Create(m Manifest) (string, error)

func (Store) Delete 

func (s Store) Delete(name string) error

func (Store) LastBackup added in v0.3.0 

func (s Store) LastBackup(applicationName string) (BackupMetadata, error)

func (Store) LastRecovery added in v0.3.0 

func (s Store) LastRecovery(applicationName string) (RecoveryMetadata, error)

func (Store) LastUpdate added in v0.3.0 

func (s Store) LastUpdate(applicationName string) (UpdateMetadata, error)

func (Store) List 

func (s Store) List() ([]Manifest, error)

func (Store) Load 

func (s Store) Load(name string) (Manifest, string, error)

func (Store) RecordLastBackup added in v0.3.0 

func (s Store) RecordLastBackup(metadata BackupMetadata) error

func (Store) RecordLastRecovery added in v0.3.0 

func (s Store) RecordLastRecovery(metadata RecoveryMetadata) error

func (Store) RecordLastUpdate added in v0.3.0 

func (s Store) RecordLastUpdate(metadata UpdateMetadata) error

func (Store) Sync 

func (s Store) Sync(m Manifest) (string, error)

Sync stores a canonical internal copy of a repository manifest while preserving already materialized runtime state. The repository file remains authoritative.

type UpdateMetadata added in v0.3.0 

type UpdateMetadata struct {
	Version         int       `json:"version"`
	Application     string    `json:"application"`
	Environment     string    `json:"environment"`
	UpdatedAt       time.Time `json:"updated_at"`
	Branch          string    `json:"branch"`
	Upstream        string    `json:"upstream"`
	FromRevision    string    `json:"from_revision"`
	ToRevision      string    `json:"to_revision"`
	Result          string    `json:"result"`
	BackupPath      string    `json:"backup_path,omitempty"`
	BackupCreatedAt time.Time `json:"backup_created_at,omitempty"`
}

func (UpdateMetadata) Validate added in v0.3.0 

func (m UpdateMetadata) Validate() error

type WorkloadBindingPlan 

type WorkloadBindingPlan struct {
	RuntimeIdentityServices []string
	FileSecretsByService    map[string][]string
}

func (WorkloadBindingPlan) Empty 

func (p WorkloadBindingPlan) Empty() bool

type WorkloadConfig 

type WorkloadConfig struct {
	Compose  string
	Services []string
}

WorkloadConfig optionally disambiguates an existing application Compose workload. Empty values keep the common case convention-based: BaseHarbor may detect one unambiguous Compose file and attach all of its services.

type WorkloadFiles 

type WorkloadFiles struct {
	RepositoryRoot string
	Compose        string
	Override       string
	Services       []string
	Project        string
	Partial        bool
}

func MaterializeWorkload 

func MaterializeWorkload(repositoryRoot string, m Manifest, runtime RuntimeFiles) (WorkloadFiles, bool, error)
