Overview

Package cluster is a generated protocol buffer package.

It is generated from these files:

cockroach/pkg/acceptance/cluster/testconfig.proto

It has these top-level messages:

StoreConfig
NodeConfig
TestConfig

Index

Constants

View Source
const CockroachBinaryInContainer = "/cockroach/cockroach"

CockroachBinaryInContainer is the container-side path to the CockroachDB binary.

View Source
const DefaultDuration = 5 * time.Second

DefaultDuration is the default duration for each individual test.

View Source
const DefaultTCP nat.Port = base.DefaultPort + "/tcp"

DefaultTCP is the default SQL/RPC port specification.

Variables

View Source
var (
	ErrInvalidLengthTestconfig = fmt.Errorf("proto: negative length found during unmarshaling")
	ErrIntOverflowTestconfig   = fmt.Errorf("proto: integer overflow")
)
View Source
var HTTPClient = http.Client{
	Timeout: base.NetworkTimeout,
	Transport: &http.Transport{
		TLSClientConfig: &tls.Config{
			InsecureSkipVerify: true,
		},
	},
}

HTTPClient is an http.Client configured for querying a cluster. We need to run with "InsecureSkipVerify" (at least on Docker) due to the fact that we cannot use a fixed hostname to reach the cluster. This in turn means that we do not have a verified server name in the certs.

Functions

func Consistent

func Consistent(ctx context.Context, c Cluster, i int) error

Consistent performs a replication consistency check on all the ranges in the cluster. It depends on a majority of the nodes being up, and does the check against the node at index i.

Types

type Cluster

type Cluster interface {
	// NumNodes returns the number of nodes in the cluster, running or not.
	NumNodes() int
	// NewClient returns a kv client for the given node.
	NewClient(context.Context, int) (*client.DB, error)
	// PGUrl returns a URL string for the given node postgres server.
	PGUrl(context.Context, int) string
	// InternalIP returns the address used for inter-node communication.
	InternalIP(ctx context.Context, i int) net.IP
	// Assert verifies that the cluster state is as expected (i.e. no unexpected
	// restarts or node deaths occurred). Tests can call this periodically to
	// ascertain cluster health.
	Assert(context.Context, testing.TB)
	// AssertAndStop performs the same test as Assert but then proceeds to
	// dismantle the cluster.
	AssertAndStop(context.Context, testing.TB)
	// ExecRoot executes the given command with super-user privileges.
	ExecRoot(ctx context.Context, i int, cmd []string) error
	// Kill terminates the cockroach process running on the given node number.
	// The given integer must be in the range [0,NumNodes()-1].
	Kill(context.Context, int) error
	// Restart terminates the cockroach process running on the given node
	// number, unless it is already stopped, and restarts it.
	// The given integer must be in the range [0,NumNodes()-1].
	Restart(context.Context, int) error
	// URL returns the HTTP(s) endpoint.
	URL(context.Context, int) string
	// Addr returns the host and port from the node in the format HOST:PORT.
	Addr(ctx context.Context, i int, port string) string
	// Hostname returns a node's hostname.
	Hostname(i int) string
}

A Cluster is an abstraction away from a concrete cluster deployment (i.e. a local docker cluster, or an AWS-provisioned one). It exposes a shared set of methods for test-related manipulation.

type Container

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

Container provides the programmatic interface for a single docker container.

func (*Container) Addr

func (c *Container) Addr(ctx context.Context, port nat.Port) *net.TCPAddr

Addr returns the TCP address to connect to.

func (*Container) Inspect

func (c *Container) Inspect(ctx context.Context) (types.ContainerJSON, error)

Inspect retrieves detailed info about a container.

func (*Container) Kill

func (c *Container) Kill(ctx context.Context) error

Kill stops a running container, without removing it.

func (*Container) Logs

func (c *Container) Logs(ctx context.Context, w io.Writer) error

Logs outputs the containers logs to the given io.Writer.

func (Container) Name

func (c Container) Name() string

Name returns the container's name.

func (*Container) Pause

func (c *Container) Pause(ctx context.Context) error

Pause pauses a running container.

func (*Container) Remove

func (c *Container) Remove(ctx context.Context) error

Remove removes the container from docker. It is an error to remove a running container.

func (*Container) Restart

func (c *Container) Restart(ctx context.Context, timeout *time.Duration) error

Restart restarts a running container. Container will be killed after 'timeout' seconds if it fails to stop.

func (*Container) Start

func (c *Container) Start(ctx context.Context) error

Start starts a non-running container.

TODO(pmattis): Generalize the setting of parameters here.

func (*Container) Stop

func (c *Container) Stop(ctx context.Context, timeout *time.Duration) error

Stop a running container.

func (*Container) Unpause

func (c *Container) Unpause(ctx context.Context) error

Unpause resumes a paused container.

func (*Container) Wait

func (c *Container) Wait(ctx context.Context) error

Wait waits for a running container to exit.

type Event

type Event struct {
	NodeIndex int
	Status    string
}

Event for a node containing a node index and the type of event.

type LocalCluster

type LocalCluster struct {
	Nodes []*testNode

	CertsDir string
	// contains filtered or unexported fields
}

LocalCluster manages a local cockroach cluster running on docker. The cluster is composed of a "volumes" container which manages the persistent volumes used for certs and node data and N cockroach nodes.

func CreateLocal

func CreateLocal(
	ctx context.Context, cfg TestConfig, logDir string, privileged bool, stopper *stop.Stopper,
) *LocalCluster

CreateLocal creates a new local cockroach cluster. The stopper is used to gracefully shutdown the channel (e.g. when a signal arrives). The cluster must be started before being used and keeps logs in the specified logDir, if supplied.

func (*LocalCluster) Addr

func (l *LocalCluster) Addr(ctx context.Context, i int, port string) string

Addr returns the host and port from the node in the format HOST:PORT.

func (*LocalCluster) Assert

func (l *LocalCluster) Assert(ctx context.Context, t testing.TB)

Assert drains the Events channel and compares the actual events with those expected to have been generated by the operations performed on the nodes in the cluster (restart, kill, ...). In the event of a mismatch, the passed Tester receives a fatal error.

func (*LocalCluster) AssertAndStop

func (l *LocalCluster) AssertAndStop(ctx context.Context, t testing.TB)

AssertAndStop calls Assert and then stops the cluster. It is safe to stop the cluster multiple times.

func (*LocalCluster) Cleanup

func (l *LocalCluster) Cleanup(ctx context.Context)

Cleanup removes the log directory if it was initially created by this LocalCluster.

func (*LocalCluster) ExecRoot

func (l *LocalCluster) ExecRoot(ctx context.Context, i int, cmd []string) error

ExecRoot runs a command as root.

func (*LocalCluster) Hostname

func (l *LocalCluster) Hostname(i int) string

Hostname implements the Cluster interface.

func (*LocalCluster) InternalIP

func (l *LocalCluster) InternalIP(ctx context.Context, i int) net.IP

InternalIP returns the IP address used for inter-node communication.

func (*LocalCluster) Kill

func (l *LocalCluster) Kill(ctx context.Context, i int) error

Kill kills the i-th node.

func (*LocalCluster) NewClient

func (l *LocalCluster) NewClient(ctx context.Context, i int) (*roachClient.DB, error)

NewClient implements the Cluster interface.

func (*LocalCluster) NumNodes

func (l *LocalCluster) NumNodes() int

NumNodes returns the number of nodes in the cluster.

func (*LocalCluster) OneShot

func (l *LocalCluster) OneShot(
	ctx context.Context,
	ref string,
	ipo types.ImagePullOptions,
	containerConfig container.Config,
	hostConfig container.HostConfig,
	name string,
) error

OneShot runs a container, expecting it to successfully run to completion and die, after which it is removed. Not goroutine safe: only one OneShot can be running at once. Adds the same binds as the cluster containers (certs, binary, etc).

func (*LocalCluster) PGUrl

func (l *LocalCluster) PGUrl(ctx context.Context, i int) string

PGUrl returns a URL string for the given node postgres server.

func (*LocalCluster) Restart

func (l *LocalCluster) Restart(ctx context.Context, i int) error

Restart restarts the given node. If the node isn't running, this starts it.

func (*LocalCluster) Start

func (l *LocalCluster) Start(ctx context.Context)

Start starts the cluster.

func (*LocalCluster) URL

func (l *LocalCluster) URL(ctx context.Context, i int) string
