Justin Cormack 2709ee88bc Split build and push, and remove push code from run

This currently only changes the `gcp` target, but is the new
model - the `build` command will only do things locally, then
you need to `push` to an image store such as GCP or other ones
in order to `run` for platforms that cannot boot directly from
a local image.

Fix #1618

Using LinuxKit on Google Cloud Platform (GCP)

This is a quick guide to run LinuxKit on GCP. A lot of internal development and CI has used Google Cloud so the support is very good; other platforms will have similar support soon.

Setup

You have two choices for authentication with Google Cloud

You can use Application Default Credentials
You can use a Service Account

Application Default Credentials

You need the Google Cloud SDK installed. Either install it from the URL or view brew (on a Mac):

brew tap caskroom/cask
brew cask install google-cloud-sdk

Or via source code:

curl -SsL https://dl.google.com/dl/cloudsdk/channels/rapid/downloads/google-cloud-sdk-151.0.0-darwin-x86_64.tar.gz
tar xzvf google-cloud-sdk-151.0.0-darwin-x86_64.tar.gz
./google-cloud-sdk/install.sh

Then, set up some environment variables (adjust as needed) and login:

export CLOUDSDK_CORE_PROJECT=<GCP project>
export CLOUDSDK_COMPUTE_ZONE=europe-west1-d
gcloud auth login

The authentication will redirect to a browser with Google login.

Also authenticate local applications with

gcloud auth application-default login

Service Account

You can use this guide to create a Service Account.

Make sure to download the credentials in JSON format and store them somewhere safe.

Build an image

Add a gcp-img output line to your yaml config, see the example in examples/gcp.yml.

Then do moby build myfile.yml

This will create a local myfile.img.tar.gz compressed image file.

Push image

Do moby push gcp -project myproject-1234 -bucket bucketname myfile.img.tar.gz to upload it to the specified bucket, and create a bootable image from the stored image.

Create an instance and connect to it

With the image created, we can now create an instance and connect to the serial port.

moby run gcp -project myproject-1234 myfile
