Can I create an instance template for a Container based OS Image

Question

I want to create an instance template such that when I use it, I should be able to launch a container when the OS starts. How do I configure this?

Answer 1

You can specify a container image in an instance template. 

By default, Compute Engine also includes in the template a Container Optimised OS image with Docker installed. 

When you use the template to create a new instance, the container is launched automatically as the instance starts up.

1. Go to the Instance Templates page.

2. Click Create instance template.

3. In the Container section, select the Deploy a container image to this VM instance checkbox.

4. Specify the Container image to use.

   • For example, you can specify gcr.io/cloud-marketplace/google/nginx1:1.12 to select an NGINX 1.12 container image from Cloud Launcher.

   • If you use a container image from Docker Hub, always specify the full Docker image name. For example, specify the following image name to deploy an Apache container image: docker.io/httpd:2.4.

5. Optionally, click Advanced container options. 

6. Click Create.
