Is it possible to download the ISO images from a different location?

I am currently working in a very restricted environment. Therefore I can't download the Alpine images from the internet. Actually I could, but the proxy of the enterprise I am working for has problems to handle large files. Furthermore it would be more efficient to download the files from a local storage.

The file .lima/colima/lima.yaml contains the following section with the specification of the image locations:

images:
    - location: https://github.com/abiosoft/alpine-lima/releases/download/colima-v0.4.2-1/alpine-lima-clm-3.14.6-aarch64.iso
      arch: aarch64
      digest: sha512:8e05be487fb6c3cf45f6378ca667f2f175c4fb07f162458ff9254f5ef4290ea94f176a6f2f9f854ab60f9668865e4d9bf0d9b24f0bb88dca4e30596855cc4013
    - location: https://github.com/abiosoft/alpine-lima/releases/download/colima-v0.4.2-1/alpine-lima-clm-3.14.6-x86_64.iso
      arch: x86_64

Is it possible to upload the images to a local storage server, e.g. a raw repository provided by Nexus, and to replace the URLs above by the local ones?

At the moment, not within Colima itself.

You can override the images with Lima by creating a ~/.lima/config/override.yaml with just the images section of the config (like your snippet). It can even point to a local file.

But it is recommended to specify the expected Colima iso images as anything otherwise would most certainly not work as desired.

I created a file called ~/.lima/config/override.yaml and put the image section from above to that file. Starting colima failed with the message, that a file called ~/.lima/config/lima.yaml is missing. I simply created an empty file with that name but it didn't help.

What did the trick was to call after the first failure limactl edit colima and to edit the file in the opened editor.

Glad you found a way around it.

We will look at providing a standard way for users to override the iso images ahead of the next release.

I think a lot of people will benefit from it. BTW, very good work!
