# 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
|
|
|
|
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 tap caskroom/cask
|
|
brew cask install google-cloud-sdk
|
|
```
|
|
|
|
Or via source code:
|
|
|
|
```shell
|
|
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:
|
|
```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 an image
|
|
|
|
When using `linuxkit build ...` to build an image, specify `-format gcp` to
|
|
build an image in a format that GCP will understand. For example:
|
|
|
|
```
|
|
linuxkit build -format gcp myprefix.yml
|
|
```
|
|
|
|
This will create a local `myprefix.img.tar.gz` compressed image file.
|
|
|
|
## Push image
|
|
|
|
Do `linuxkit push gcp -project myproject-1234 -bucket bucketname myprefix.img.tar.gz` to upload it to the
|
|
specified bucket, and create a bootable image from the stored image.
|
|
|
|
Alternatively, you can set the project name and the bucket name using environment variables, `CLOUDSDK_CORE_PROJECT` and `CLOUDSDK_IMAGE_BUCKET`.
|
|
See the constant values defined in [`src/cmd/linuxkit/run_gcp.go`](../src/cmd/linuxkit/run_gcp.go) for the complete list of the supported environment variables.
|
|
|
|
## Create an instance and connect to it
|
|
|
|
With the image created, we can now create an instance and connect to
|
|
the serial port.
|
|
|
|
```
|
|
linuxkit run gcp -project myproject-1234 myprefix
|
|
```
|
|
|
|
## Nested Virtualization
|
|
|
|
Google Cloud offers [Nested
|
|
Virtualization](https://cloud.google.com/compute/docs/instances/enable-nested-virtualization-vm-instances)
|
|
as a beta feature. `linuxkit` supports this by pushing the image with
|
|
`linuxkit push gcp -nested-virt <other options>` and `linuxkit run gcp
|
|
-nested-virt <other options>`. The `push` sets the appropriate license
|
|
on the image while the `run` argument ensures that the CPU is at least
|
|
Haswell or newer.
