Hi there @eaglemoor,

It looks like that you don’t have bash installed inside the container. You could instead try using sh:

RUN /bin/sh

Or alternatively, you could install bash. Depending on the Docker image that you are using you could add an install step in your Dockerfile. For example if you are using Apline as your base image this would look like this:

RUN apk update && apk add bash

If you are using Ubuntu or Debian it would need to be updated to apt update && apt install bash.

Let me know how it goes. Regards, Bobby

in case someone else comes across this. i encountered this issue when building images on the m1 max macbook (ARM64).

i believe this is because the VM host DO uses expects AMD64 only.

you can confirm this with:

docker inspect <image ID> --format '{{.Architecture}}'

# you can get image ID with
docker image ls

when built through docker desktop on macOS you get

docker inspect <image ID> --format '{{.Architecture}}'
arm64

when built on a native linux docker host you get

docker inspect <image ID> --format '{{.Architecture}}'
amd64

if you get arm64 then you will see this issue when you deploy.

here is another DO thread discussing this in detail

If you are using an Apple Silicon to build your images, you need to use amd64 images (default is arm64 on those macs which is not supported by DO)

Dockerfile

FROM --platform=linux/amd64 node:18-alpine
# Rest of your docker file...
