Types

type BuildOptions added in v0.22.3 

type BuildOptions struct {
	// Tags for the Docker image
	Tags []string

	// Build args to pass the 'docker build' command
	BuildArgs []string

	// Target build arg to pass to the 'docker build' command
	Target string

	// All architectures to target in a multiarch build. Configuring this variable will cause terratest to use docker
	// buildx to construct multiarch images.
	// You can read more about multiarch docker builds in the official documentation for buildx:
	// https://docs.docker.com/buildx/working-with-buildx/
	// NOTE: This list does not automatically include the current platform. For example, if you are building images on
	// an Apple Silicon based MacBook, and you configure this variable to []string{"linux/amd64"} to build an amd64
	// image, the buildx command will not automatically include linux/arm64 - you must include that explicitly.
	Architectures []string

	// Whether or not to push images directly to the registry on build. Note that for multiarch images (Architectures is
	// not empty), this must be true to ensure availability of all architectures - only the image for the current
	// platform will be loaded into the daemon (due to a limitation of the docker daemon), so you won't be able to run a
	// `docker push` command later to push the multiarch image.
	// See https://github.com/moby/moby/pull/38738 for more info on the limitation of multiarch images in docker daemon.
	Push bool

	// Whether or not to load the image into the docker daemon at the end of a multiarch build so that it can be used
	// locally. Note that this is only used when Architectures is set, and assumes the current architecture is already
	// included in the Architectures list.
	Load bool

	// Custom CLI options that will be passed as-is to the 'docker build' command. This is an "escape hatch" that allows
	// Terratest to not have to support every single command-line option offered by the 'docker build' command, and
	// solely focus on the most important ones.
	OtherOptions []string

	// Set a logger that should be used. See the logger package for more info.
	Logger *logger.Logger
}

BuildOptions defines options that can be passed to the 'docker build' command.

	// Username or UID
	User string

	// Bind mount these volume(s) when running the container
	Volumes []string

	// Custom CLI options that will be passed as-is to the 'docker run' command. This is an "escape hatch" that allows
