Types

type ContainerOutput 

type ContainerOutput struct {
	Stdout, Stderr string
}

func Output 

func Output(ctx context.Context, client client.APIClient, id string) (ContainerOutput, error)

Output waits for the container to end running and returns its output.

type ExecResult 

type ExecResult struct {

}

ExecResult represents a result returned from Exec()

func Exec

Exec executes a command inside a container, returning the result containing stdout, stderr, and exit code. Note:

  • this is a synchronous operation;
  • cmd stdin is closed.

func ExecT 

func ExecT(ctx context.Context, t testing.TB, apiClient client.APIClient, id string, cmd []string, ops ...func(*types.ExecConfig)) ExecResult

ExecT calls Exec() and aborts the test if an error occurs.

func (ExecResult) AssertSuccess 

func (res ExecResult) AssertSuccess(t testing.TB)

AssertSuccess fails the test and stops execution if the command exited with a nonzero status code.

func (ExecResult) Combined 

func (res ExecResult) Combined() string

Combined returns combined stdout and stderr output of a command run by Exec()

func (ExecResult) Stderr 

func (res ExecResult) Stderr() string

Stderr returns stderr output of a command run by Exec()

func (ExecResult) Stdout 

func (res ExecResult) Stdout() string

Stdout returns stdout output of a command run by Exec()

type RunResult 

type RunResult struct {
	ContainerID string
	ExitCode    int
	Stdout      *bytes.Buffer
	Stderr      *bytes.Buffer
}

func RunAttach 

func RunAttach(ctx context.Context, t *testing.T, apiClient client.APIClient, ops ...func(config *TestContainerConfig)) RunResult

type TestContainerConfig 

type TestContainerConfig struct {
	Name             string
	Config           *container.Config
	HostConfig       *container.HostConfig
	NetworkingConfig *network.NetworkingConfig
