Docker !

Arguments

Name	Type	Description
registry	String	the address of the registry to authenticate with
username	String	the username for authenticating with the registry
password	Secret	the password for authenticating with the registry

func (m *myModule) example() *Docker  {
	return dag.
			Docker()
}

def example() -> dag.Docker:
	return (
		dag.docker()
	)

@func()

		.docker()
}

Types

Docker 🔗

Docker dagger module

build() 🔗

Build an image using a Dockerfile. Supports multi-platform images

Return Type

Build !

Arguments

Name	Type	Default Value	Description
dir	Directory !	-	the path to a directory that will be used as the docker context
file	String	"Dockerfile"	the path to the Dockfile
args	[String ! ]	-	a list of build arguments in the format of arg=value
target	String	-	the name of a target build stage
platform	[Scalar ! ]	["linux/amd64"]	a list of target platforms for cross-compilation

Example

dagger -m github.com/purpleclay/daggerverse/docker@2a439e2b327ff561bea05a4edddd5276ac42407f call \
 build --dir DIR_PATH

func (m *myModule) example(dir *Directory) *DockerBuild  {
	return dag.
			Docker().
			Build(dir)
}

@function
def example(dir: dagger.Directory) -> dag.DockerBuild:
	return (
		dag.docker()
		.build(dir)
	)

@func()
example(dir: Directory): DockerBuild {
	return dag
		.docker()
		.build(dir)
}

Build 🔗

DockerBuild contains an image built from the provided Dockerfile, it serves as an intermediate type for chaining other functions. If multiple platforms were provided, then multiple images will exist

save() 🔗

Save the built image as a tarball ready for exporting. A tarball will be generated using the following convention <name>@<platform>.tar (e.g. image~linux-amd64.tar)

Return Type

Directory !

Arguments

Name	Type	Default Value	Description
name	String	"image"	a name for the exported tarball

Example

dagger -m github.com/purpleclay/daggerverse/docker@2a439e2b327ff561bea05a4edddd5276ac42407f call \
 build --dir DIR_PATH \
 save

func (m *myModule) example(dir *Directory) *Directory  {
	return dag.
			Docker().
			Build(dir).
			Save()
}

@function
def example(dir: dagger.Directory) -> dagger.Directory:
	return (
		dag.docker()
		.build(dir)
		.save()
	)

@func()
example(dir: Directory): Directory {
	return dag
		.docker()
		.build(dir)
		.save()
}

image() 🔗

Retrieves a built image for a given platform as a container

Return Type

Container !

Arguments

Name	Type	Default Value	Description
platform	Scalar	"linux/amd64"	the platform of the docker image to return

Example

dagger -m github.com/purpleclay/daggerverse/docker@2a439e2b327ff561bea05a4edddd5276ac42407f call \
 build --dir DIR_PATH \
 image

func (m *myModule) example(dir *Directory) *Container  {
	return dag.
			Docker().
			Build(dir).
			Image()
}

@function
def example(dir: dagger.Directory) -> dagger.Container:
	return (
		dag.docker()
		.build(dir)
		.image()
	)

@func()
example(dir: Directory): Container {
	return dag
		.docker()
		.build(dir)
		.image()
}

publish() 🔗

Publish the built image to a target registry. Supports publishing of mulit-platform images

Return Type

String !

Arguments

Name	Type	Default Value	Description
ref	String !	-	a fully qualified image reference without tags
tags	[String ! ]	["latest"]	a list of tags that should be published with the image

Example

 build --dir DIR_PATH \
 publish --ref string

func (m *myModule) example(ctx context.Context, dir *Directory, ref string) string  {
	return dag.
			Docker().
			Build(dir).
			Publish(ctx, ref)
}

@function
async def example(dir: dagger.Directory, ref: str) -> str:
	return await (
		dag.docker()
		.build(dir)
		.publish(ref)
	)

@func()
async example(dir: Directory, ref: string): Promise<string> {
	return dag
