Functions

func Monitor added in v1.4.3 

func Monitor(ctx context.Context, onRecord func(rec StatsRecord)) error

Monitor: теперь первым делом на "die" печатаем логи, а уже потом — ресурсы.

Types

type ContainerConfig 

type ContainerConfig struct {
	Image string
	Cmd   []string
	Tty   bool
}

ContainerConfig struct with Image, Cmd and Tty fields

type ContainerStatsSummary added in v1.3.2 

type ContainerStatsSummary struct {
	Duration   time.Duration // сколько контейнер жил
	CPUPercent float64       // CPU% на момент снимка
	MemUsage   uint64        // текущее потребление памяти (bytes)
	MemLimit   uint64        // лимит памяти (bytes) — будет удобно для процента
	MemPercent float64       // процент использования памяти (например, 0.1234 => 12.34%)
}

ContainerStatsSummary — структура, в которую мы запомним итоговые цифры.

type DockerManager 

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

DockerManager struct with cli field

func NewDockerManager 

func NewDockerManager() (*DockerManager, error)

Docker manager constructor

func (*DockerManager) Create 

func (dm *DockerManager) Create(config ContainerConfig) (string, error)

Function to create a container

func (*DockerManager) EnsureImage added in v1.2.0 

func (dm *DockerManager) EnsureImage(imageName string) error

ensureImage checks if there is an image of the container if not it pulls it.

func (*DockerManager) GetLogs 

func (dm *DockerManager) GetLogs(containerID string) (string, error)

Function to get logs from a container

func (*DockerManager) GetStats added in v0.11.0 

func (dm *DockerManager) GetStats(containerID string) (string, error)

Function to get stats from docker container and format them

func (*DockerManager) GetStatsOneShot added in v1.5.10 

func (dm *DockerManager) GetStatsOneShot(containerID string, startTime time.Time) (ContainerStatsSummary, error)

GetStatsOneShot получает «одноразовый» снимок stats сразу после exit. Его удобно вызывать ПОСЛЕ Wait, но до того, как вы удалите контейнер.

func (*DockerManager) IsRunning added in v0.5.1 

func (dm *DockerManager) IsRunning(containerID string) (bool, error)

Function to check if a container is running

func (*DockerManager) Ping added in v1.2.2 

func (dm *DockerManager) Ping() error

func (*DockerManager) Remove 

func (dm *DockerManager) Remove(containerID string) error

Function to remove a container

func (*DockerManager) Start 

func (dm *DockerManager) Start(containerID string) error

Function to start a container

func (*DockerManager) Stop 

func (dm *DockerManager) Stop(containerID string, timeout int) error

Function to stop a container

func (*DockerManager) Wait added in v0.4.0 

func (dm *DockerManager) Wait(containerID string) (container.WaitResponse, error)

Function to wait for a container

type Manager 

type Manager interface {
	Create(config ContainerConfig) (string, error)
	Start(id string) error
	Stop(id string, timeout int) error
	Remove(id string) error
	GetLogs(id string) (string, error)
	Wait(id string) (container.WaitResponse, error)
	IsRunning(id string) (bool, error)
	GetStats(containerID string) (string, error)
	EnsureImage(image string) error
	GetStatsOneShot(containerID string, startTime time.Time) (ContainerStatsSummary, error)
	Ping() error
}

Manager interface with methods to manage containers

type StatsRecord added in v1.4.3 

type StatsRecord struct {
	ID            string        `json:"id"`
	StartTime     time.Time     `json:"start_time"`
	EndTime       time.Time     `json:"end_time"`
	Duration      time.Duration `json:"duration"`
	CPUUsageNs    uint64        `json:"cpu_usage_ns"`
	MemUsageBytes uint64        `json:"mem_usage_bytes"`
	MemMaxBytes   uint64        `json:"mem_max_bytes"`
}

StatsRecord holds the final stats for one container run.
