Functions

func CreateClientOpts 

func CreateClientOpts(_ context.Context, env Env) ([]client.Opt, error)

Adapted from client.FromEnv

Supported environment variables: DOCKER_HOST to set the url to the docker server. DOCKER_API_VERSION to set the version of the API to reach, leave empty for latest. DOCKER_CERT_PATH to load the TLS certificates from. DOCKER_TLS_VERIFY to enable or disable TLS verification, off by default.

	// Some Kubernetes contexts have a Docker daemon that they use directly
	// as their container runtime. Any images built on that daemon will
	// show up automatically in the runtime.
	//
	// We used to store this as a property of the k8s env but now store it as a field of the Docker Env, because this
	// really affects how we interact with the Docker Env (rather than
	// how we interact with the K8s Env).
	//
	// In theory, you can have more than one, but in practice,
	// this is very difficult to set up.
	BuildToKubeContexts []string

	// If the env failed to load for some reason, propagate that error
	// so that we can report it when the user tries to do a docker_build.
