tutor config save interpolates values and replaces them in config

[misilot]

Bug description

Tutor overwrites values in config.yml, where I am trying to update the Registry for our openedx and mfe images, so they can be built on one system and promoted to production.

How to reproduce

edit the local config.yml in the TUTOR_ROOT directory.
Add:

DOCKER_IMAGE_OPENEDX: docker.io/orgname/openedx:{{ TUTOR_VERSION }}"
MFE_DOCKER_IMAGE: docker.io/orgname/openedx-mfe:19.0.0-indgio

I'd actually like to use this, but MFE_VERSION isn't available to tutor config save

MFE_DOCKER_IMAGE: docker.io/orgname/openedx-mfe:{{ MFE_VERSION }}

run tutor config save
Get the following output:

DOCKER_IMAGE_OPENEDX: docker.io/orgname/openedx:19.0.1
MFE_DOCKER_IMAGE: docker.io/orgname/openedx-mfe:19.0.0-indigo

I'd like to have it pull like it does the correct values TUTOR_VERSION and MFE_VERSION so the values mimic and get updated whenever the plugins and application are updated.

Environment

Ubuntu 24.04
tutor, version 19.0.1
Additional context

[regisb]

Tutor's config.yml includes only rendered values. Editing this file manually is never a good idea. If you need to modify the config values, you should create a plugin. In your particular case, you should make use of the following filter: https://docs.tutor.edly.io/reference/api/hooks/catalog.html#tutor.hooks.Filters.CONFIG_OVERRIDES

I'm closing this since this isn't an actual issue. For support on how to use Tutor, please use the Open edX forum: https://discuss.openedx.org/
