I was going through this pulumi tutorial (<https://www.pulumi.com/learn/pulumi-fundamentals/configure-and-provision/>), but it's failing with error(container exit...) . After inspecting the image built, I found that it is taking the "Architecture": "arm64" for building image, and I am using Ubuntu amd64. I am sure it's the reason why it's failing. But not sure why it is taking the arm64 eventhough the Dockerfile mentioned "FROM mongo:focal"? Any idea??

Are you running this on a macbook M1 by any chance?

<@U033KKRC6HY> No, I am using Ubuntu 22.04

But not on an ARM architecture?  Normally the docker engine takes the info, which image to pull from the underling architecture.

I for example. work on a M1 so I have to add:

`FROM --platform=linux/amd64 xxx` to my dockerfile so it uses explicit the amd64 as from

If I am deploy later to e.g Kubernetes on linux

In the Dockerfile, "FROM mongo:focal" is mentioned. (using this repo: <https://github.com/pulumi/tutorial-pulumi-fundamentals>) The Dockerfile is in data folder.

Also, I tried to pull the image(mongo:focal), it is pulling the amd64 one, but why pulumi is pulling the arm one?

The mongo image is getting built using this:

```// build our mongodb image!
const mongoImage = new docker.RemoteImage("mongo", {
    name: "pulumi/tutorial-pulumi-fundamentals-database-local:latest",
});```
