Functions

func LoadTLSConfig 

func LoadTLSConfig(files TLSFiles) (*tls.Config, error)

LoadTLSConfig loads provider trust and client identity from a complete projection.

Types

type Client 

type Client struct {
	// contains filtered or unexported fields
}

Client is a bounded client for the private execution-provider gRPC API.

func New 

func New(endpoint string, tlsConfig *tls.Config) (*Client, error)

New constructs a production mTLS execution-provider client. Endpoint is a plain host:port authority; URI schemes and alternate resolvers are rejected.

func NewWithTLSFiles added in v0.0.48 

func NewWithTLSFiles(endpoint string, files TLSFiles) (*Client, error)

NewWithTLSFiles owns a reloadable connection; invalid material withdraws active authority instead of allowing a stale channel to continue.

func (*Client) AbortReference

func (c *Client) AcquireRun(ctx context.Context, req executionenv.RunClaimRequest) (executionenv.RunClaim, error)

AcquireRun acquires one environment-wide run claim.

func (*Client) Attach 

func (c *Client) Attach(ctx context.Context, req executionenv.AttachEnvironmentRequest) (executionenv.AttachEnvironmentResponse, error)

Attach obtains current allocation state for an exact environment reference.

func (*Client) CancelCommand 

func (c *Client) CancelCommand(ctx context.Context, req executionenv.CommandQueryRequest) (executionenv.CommandStatusResponse, error)

CancelCommand cancels a command after the request has been authorized.

func (c *Client) CancelReferenceDelete(ctx context.Context, req executionenv.ReferenceRequest) error

func (*Client) Close 

func (c *Client) Close()

Close releases the provider connection.

func (*Client) CommitReference 

func (c *Client) CommitReference(ctx context.Context, req executionenv.ReferenceRequest) error

func (*Client) ConfirmReferenceDelete 

func (c *Client) ConfirmReferenceDelete(ctx context.Context, req executionenv.ReferenceRequest) error

func (*Client) DeleteRetiredEnvironment 

func (c *Client) DeleteRetiredEnvironment(ctx context.Context, ref executionenv.EnvironmentRef, owner executionenv.Owner, expectedPVCUID, operationID string) error

DeleteRetiredEnvironment deletes retained storage after retirement proof.

func (*Client) EnsureTemplate added in v0.0.48 

func (c *Client) EnsureTemplate(ctx context.Context, binding, id, revision string, owner executionenv.Owner, operationID string) (executionenv.EnsureEnvironmentResponse, error)

func (*Client) File 

func (c *Client) File(ctx context.Context, req executionenv.FileRequest) (executionenv.FileResponse, error)

File executes one authorized filesystem operation.

func (*Client) FindReferenceIntent 

func (c *Client) FindReferenceIntent(ctx context.Context, owner executionenv.Owner, environment executionenv.EnvironmentRef, binding string) (executionenv.ReferenceIntent, error)

func (*Client) Invoke added in v0.0.48 

func (c *Client) Invoke(ctx context.Context, method string, args, reply any, opts ...grpc.CallOption) error

Invoke pins the transport for the complete RPC, including its terminal reply.

func (*Client) ListAllReferenceIntents 

func (c *Client) ListAllReferenceIntents(ctx context.Context) ([]executionenv.ReferenceIntent, error)

func (*Client) ListExecutionTemplates added in v0.0.48 

func (c *Client) ListExecutionTemplates(ctx context.Context) (*executionv1.ListExecutionTemplatesResponse, error)

ListExecutionTemplates returns only operator-authorized display projections.

func (*Client) ListReferenceIntents 

func (c *Client) ListReferenceIntents(ctx context.Context, owner executionenv.Owner) ([]executionenv.ReferenceIntent, error)

func (*Client) NewStream added in v0.0.48 

func (c *Client) NewStream(ctx context.Context, desc *grpc.StreamDesc, method string, opts ...grpc.CallOption) (grpc.ClientStream, error)

func (*Client) PrepareReferenceDelete 

func (c *Client) PrepareReferenceDelete(ctx context.Context, req executionenv.ReferenceRequest) error

func (*Client) RecoverEnvironment 

func (c *Client) RecoverEnvironment(ctx context.Context, req executionenv.RetireEnvironmentRequest) error

RecoverEnvironment clears a fence only after the provider verifies exact terminal evidence.

func (*Client) ReleaseReference 

func (c *Client) ReleaseReference(ctx context.Context, req executionenv.ReferenceReleaseRequest) error

ReleaseReference releases one durable binding reference.

func (*Client) ReleaseRun 

func (c *Client) ReleaseRun(ctx context.Context, req executionenv.RunClaimRequest) error

func (*Client) ReloadTLS added in v0.0.48 

func (c *Client) ReloadTLS() error

ReloadTLS publishes a complete, stable identity/trust bundle. Only same-identity renewal under unchanged trust may drain existing RPCs; withdrawal closes them.

func (*Client) RenewRun 

func (c *Client) RenewRun(ctx context.Context, req executionenv.RunClaimRequest) (executionenv.RunClaim, error)

func (*Client) ReplaceExecutor 

func (c *Client) ReplaceExecutor(ctx context.Context, req executionenv.RetireEnvironmentRequest) error

ReplaceExecutor requests UID-checked administrative executor replacement.

func (*Client) ReserveSuccessor 

func (c *Client) ReserveSuccessor(ctx context.Context, req executionenv.ReferenceRequest) error

func (*Client) RetireEnvironment 

func (c *Client) RetireEnvironment(ctx context.Context, req executionenv.RetireEnvironmentRequest) error

RetireEnvironment requests administrative retirement.

func (*Client) RevokeEnvironment 

func (c *Client) RevokeEnvironment(ctx context.Context, ref executionenv.EnvironmentRef, owner executionenv.Owner, expectedGeneration uint64, operationID string) (uint64, error)

RevokeEnvironment atomically fences active runs and replays a matching operation receipt.

func (*Client) RunTLSReload added in v0.0.48 

func (c *Client) RunTLSReload(ctx context.Context, interval time.Duration)

RunTLSReload checks projected credentials until shutdown; renewal is not independent of security-policy publication.

StartCommand executes one foreground command.

func (*Client) ValidateTemplate added in v0.0.48 

func (c *Client) ValidateTemplate(ctx context.Context, id, revision string) (*executionv1.ValidateTemplateResponse, error)

func (p *Provider) ListExecutionTemplates(ctx context.Context, principal *session.Principal) ([]server.ExecutionTemplateInfo, string, error)

func (*Provider) ListReferenceIntents 

func (p *Provider) ListReferenceIntents(ctx context.Context, limit int) ([]server.ReferenceIntent, error)

func (p *Provider) PrepareReferenceDelete(ctx context.Context, req server.PlacementSuccessorRequest) (server.ReferenceDeleteHandle, error)

func (*Provider) Reattach 

func (p *Provider) Reattach(ctx context.Context, req server.PlacementReattachRequest) (server.PlacementBinding, error)

Reattach exactly resolves a persisted remote environment for its binding.
