```Cannot connect to the Docker daemon at unix:///var/run/docker.sock```
you don't have docker running on your local machine. make sure the service is started

Hi <@UCWG26BH7> any suggestion which container is best suited ? i was using below..

platform: linux
image_resource:
  type: docker-image
  source:
    repository: pulumi/pulumi-nodejs
    tag: "3.6.1"

are there any containers available which has pre build docker image with pulumi &amp; nodejs ?

<@U028C2T9J6M> are you trying to build a docker image from inside a docker container?

we spin up a container &amp; then run scripts

platform: linux
image_resource:
  type: docker-image
  source:
    repository: pulumi/pulumi
    tag: "latest"

Right, but you’ll need to enable docker in docker for this to work 

*error:* Cannot connect to the Docker daemon at unix:///var/run/docker.sock. Is the docker daemon running?

We don’t have one with support for this I’m afraid
