Ops can integrate with your existing Google Cloud Platform (GCP) account. You can use Ops CLI to create and upload an image in GCP account. Once, you have uploaded image, you can also create an instance with a particular image using CLI.

Pre-requisites

1. Create a Service Account (SA) in your GCP account and download the Service Account key json file.

2. Please make sure your Service Account has access to the Google Compute Engine and Google Storage.

3. Get the name of your Google Cloud account project where you would be creating images and instances.

4. Create a bucket in Google Cloud storage for image artifacts storage.

5. Please make sure you export GOOGLE_APPLICATION_CREDENTIALS with the Service Account key json file path, before invoking below commands.

   $ export GOOGLE_APPLICATION_CREDENTIALS=~/service-key.json

Image Operations

Create Image

If you have already created an Ops project, you can update your existing config.json. You need to add CloudConfig which mentions specific details like ProjectID, BucketName.

{
    "CloudConfig" :{
        "ProjectID" :"prod-1000",
        "Zone": "us-west1-b",
        "BucketName":"my-deploy"
    },
    "RunConfig" : {
        "Memory": "2G"
    }
}

Once, you have updated config.json you can create an image in Google Cloud with the following command.

$ ops image create -c config.json <image_name>

For creating an image using a particular package, you need to provide the package name to ops image create command with -p option.

$ ops image create -c config.json -p node_v11.5.0 -a ex.js

List Images

You can list existing images on Google cloud with ops image list.

$ ops image list
+--------------------+--------+-------------------------------+
|        NAME        | STATUS |            CREATED            |
+--------------------+--------+-------------------------------+
| nanos-main-image   | READY  | 2019-03-21T15:06:17.567-07:00 |
+--------------------+--------+-------------------------------+
| nanos-node-image   | READY  | 2019-04-16T23:16:03.145-07:00 |
+--------------------+--------+-------------------------------+
| nanos-server-image | READY  | 2019-03-21T15:50:04.456-07:00 |
+--------------------+--------+-------------------------------+

Delete Image

ops image delete -i <imagename> can be used to delete an image from Google Cloud.

$ ops delete image -i nanos-main-image

Instance Operations

Create Instance

After the successful creation of an image in Google Cloud, we can create an instance from an existing image.

You need to export GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT and GOOGLE_CLOUD_ZONE before firing command.

$ export GOOGLE_CLOUD_PROJECT=prod-1000
$ export GOOGLE_CLOUD_ZONE=us-west1-b
$ ops instance create -i <image_name>

Alternatively, you can pass project-id and zone with cli options.

$ ops instance create -p prod-1000 -z us-west1-b -i <image_name>

You can also pass config, if you have mentioned project-id and zone in project's config.json.

$ ops instance create -c config.json -i <image_name>

List Instances

You can list instance on Google Cloud using ops instance list command.

You need to export GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT and GOOGLE_CLOUD_ZONE before firing command.

$ export GOOGLE_CLOUD_PROJECT=prod-1000
$ export GOOGLE_CLOUD_ZONE=us-west1-b
$ ops instance list
+-----------------------------+---------+-------------------------------+-------------+--------------+
|            NAME             | STATUS  |            CREATED            | PRIVATE IPS |  PUBLIC IPS  |
+-----------------------------+---------+-------------------------------+-------------+--------------+
| nanos-main-image-1556601450 | RUNNING | 2019-04-29T22:17:34.609-07:00 | 10.240.0.40 | 34.83.204.40 |
+-----------------------------+---------+-------------------------------+-------------+--------------+

Alternatively you can pass project-id and zone with cli options.

$ ops instance list -p prod-1000 -z us-west1-b

Get Logs for Instance

You can get logs from serial console of a particular instance using ops instance logs command.

You need to export GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT and GOOGLE_CLOUD_ZONE before firing command.

$ export GOOGLE_CLOUD_PROJECT=prod-1000
$ export GOOGLE_CLOUD_ZONE=us-west1-b
$ ops instance logs <instance_name>

Alternatively you can pass project-id and zone with cli options.

$ ops instance logs -p prod-1000 -z us-west1-b

Delete Instance

ops instance delete command can be used to delete instance on Google Cloud.

You need to export GOOGLE_APPLICATION_CREDENTIALS, GOOGLE_CLOUD_PROJECT and GOOGLE_CLOUD_ZONE before firing command.

$ export GOOGLE_CLOUD_PROJECT=prod-1000
$ export GOOGLE_CLOUD_ZONE=us-west1-b
$ ops instance delete my-instance-running

Alternatively you can pass project-id and zone with cli options.

$ ops instance delete -p prod-1000 -z us-west1-b my-instance-running
