Types

type ClientContext 

type ClientContext struct {
	Name           string
	Description    string
	DockerEndpoint string
	Current        bool
	Error          string
}

ClientContext is a context for display

type ContainerContext 

type ContainerContext struct {
	HeaderContext

	// FieldsUsed is used in the pre-processing step to detect which fields are
	// used in the template. It's currently only used to detect use of the .Size
	// field which (if used) automatically sets the '--size' option when making
	// the API call.
	FieldsUsed map[string]any
	// contains filtered or unexported fields
}

ContainerContext is a struct used for rendering a list of containers in a Go template.

func NewContainerContext 

func NewContainerContext() *ContainerContext

NewContainerContext creates a new context for rendering containers

func (*ContainerContext) Command 

func (c *ContainerContext) Command() string

Command returns's the container's command. If the trunc option is set, the returned command is truncated (ellipsized).

func (*ContainerContext) CreatedAt 

func (c *ContainerContext) CreatedAt() string

CreatedAt returns the "Created" date/time of the container as a unix timestamp.

func (*ContainerContext) ID 

func (c *ContainerContext) ID() string

ID returns the container's ID as a string. Depending on the `--no-trunc` option being set, the full or truncated ID is returned.

func (*ContainerContext) Image 

func (c *ContainerContext) Image() string

Image returns the container's image reference. If the trunc option is set, the image's registry digest can be included.

func (*ContainerContext) Label 

func (c *ContainerContext) Label(name string) string

Label returns the value of the label with the given name or an empty string if the given label does not exist.

func (*ContainerContext) Labels 

func (c *ContainerContext) Labels() string

Labels returns a comma-separated string of labels present on the container.

func (*ContainerContext) LocalVolumes 

func (c *ContainerContext) LocalVolumes() string

LocalVolumes returns the number of volumes using the "local" volume driver.

func (*ContainerContext) MarshalJSON 

func (c *ContainerContext) MarshalJSON() ([]byte, error)

MarshalJSON makes ContainerContext implement json.Marshaler

func (*ContainerContext) Mounts 

func (c *ContainerContext) Mounts() string

Mounts returns a comma-separated string of mount names present on the container. If the trunc option is set, names can be truncated (ellipsized).

func (*ContainerContext) Names 

func (c *ContainerContext) Names() string

Names returns a comma-separated string of the container's names, with their slash (/) prefix stripped. Additional names for the container (related to the legacy `--link` feature) are omitted.

func (*ContainerContext) Networks 

func (c *ContainerContext) Networks() string

Networks returns a comma-separated string of networks that the container is attached to.

func (*ContainerContext) Ports 

func (c *ContainerContext) Ports() string

Ports returns a comma-separated string representing open ports of the container e.g. "0.0.0.0:80->9090/tcp, 9988/tcp" it's used by command 'docker ps' Both published and exposed ports are included.

func (*ContainerContext) RunningFor 

func (c *ContainerContext) RunningFor() string

RunningFor returns a human-readable representation of the duration for which the container has been running.

Note that this duration is calculated on the client, and as such is influenced by clock skew between the client and the daemon.

func (*ContainerContext) Size 

func (c *ContainerContext) Size() string

Size returns the container's size and virtual size (e.g. "2B (virtual 21.5MB)")

func (*ContainerContext) State 

func (c *ContainerContext) State() string

State returns the container's current state (e.g. "running" or "paused")

func (*ContainerContext) Status 

func (c *ContainerContext) Status() string

Status returns the container's status in a human readable form (for example, "Up 24 hours" or "Exited (0) 8 days ago")

type Context 

type Context struct {
	// Output is the output stream to which the formatted string is written.
	Output io.Writer
	// Format is used to choose raw, table or custom format for the output.
	Format Format
	// Trunc when set to true will truncate the output of certain fields such as Container ID.
	Trunc bool
	// contains filtered or unexported fields
}

Context contains information required by the formatter to print the output as desired.

func (*Context) Write
