This commit implements `moby run gcp` which allows for testing of moby images on the Google Cloud Platform This backend attaches (via SSH) to the serial console. It generates instance-only SSH keys and adds the public key to the image metadata. These are used by the `moby` tool only. It will also automatically upload a file and creates an image if the prefix given to `moby run` is a filename Signed-off-by: Dave Tucker <dt@docker.com>

# Using Moby on Google Cloud Platform (GCP)
|
|
|
|
This is a quick guide to run Moby on GCP.
|
|
|
|
## Setup
|
|
|
|
You have two choices for authentication with Google Cloud
|
|
|
|
1. You can use [Application Default Credentials](https://developers.google.com/identity/protocols/application-default-credentials)
|
|
2. You can use a Service Account
|
|
|
|
### Application Default Credentials
|
|
|
|
You need the [Google Cloud SDK](https://cloud.google.com/sdk/)
|
|
installed. Either install it from the URL or view `brew` (on a Mac):
|
|
```shell
|
|
brew install google-cloud-sdk
|
|
```
|
|
|
|
Then, set up some environment variables (adjust as needed) and login:
|
|
```shell
|
|
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](https://cloud.google.com/compute/docs/access/create-enable-service-accounts-for-instances#createanewserviceaccount)
|
|
to create a Service Account.
|
|
|
|
Make sure to download the credentials in JSON format and store them somewhere safe.
|
|
|
|
## Build a moby image
|
|
|
|
Add a `gcp` output line to your yaml config, see the example in `examples/gcp.yml`.
|
|
|
|
Then do `./bin/moby myfile.yml`
|
|
|
|
This will create a local `myfile.img.tar.gz` compressed image file, upload it to the
|
|
specified bucket, and create a bootable 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
|
|
```
