How to override system-imaging config variables?

[karlatec]

Hi!

I am trying to override a variable from system-imaging section of configuration file.

[system-imaging.images.fedora_43-x86_64]
cloud.url = "REPLACED_BY_ENV_VARIABLE_IN_WORKFLOW"

I don't want to put an actual value in there because it's supposed to be a variable - the URL will change.

I followed https://cijoe.readthedocs.io/en/latest/configs/index.html and tried:

1. Overriding using env variables:
   Which says Convert the configuration path and name to uppercase. Replace any dots (.) with underscores (_). This would result in variable like: SYSTEM-IMAGING_IMAGES_GUEST_OS_X86_64_CLOUD_URL. But this doesn't work, as there's a dash in the variable name.

export SYSTEM-IMAGING_IMAGES_GUEST_OS_X86_64_CLOUD_URL=test
-bash: export: `SYSTEM-IMAGING_IMAGES_GUEST_OS_X86_64_CLOUD_URL=test': not a valid identifier

2. Overriding using multiple configuration files.
   I removed cloud.url from the configuration file and created a second configuration file with just:

[system-imaging.images.fedora_43-x86_64]
cloud.url = "https://some-url.com"

and then run with -c config1.toml -c config2.toml, but got an error about cloud.path not being defined. Seems like all configuration from config1 was ignored, instead of just overriding parts defined in config2?

Thank you for catching this :)

For your first problem: I will update the code, so it replaces both dots AND dashes with underscores. And update the docs to match this :)

For the second problem, can I ask which version of cijoe you are running? This should have been fixed by commit 27e652f, and when testing myself, I get no problems with undefined keys. Please note that in the example configuration file for system-imaging, the key is fedora-43-x86_64 with two dashes, not fedora_43-x86_64 as you write here - maybe this could be the problem, unless you have changed it locally.
You can also check the cijoe-output/config.orig file that is generated when compiling multiple configuration files into one. :)

For the second problem, can I ask which version of cijoe you are running?

It's ghcr.io/refenv/cijoe-docker:v0.9.54. which I see was released ~ Jun 2025, and you change is from Sep 2025. I'll give it a go with new version and let you know.

Please note that in the example configuration file for system-imaging, the key is fedora-43-x86_64 with two dashes, not fedora_43-x86_64 as you write here - maybe this could be the problem, unless you have changed it locally.

More likely I've made a typo when creating the issue :) For this second issue I wasn't copy-pasting.

Can I ask for a push of v0.9.58 version to ghcr.io?

docker pull ghcr.io/refenv/cijoe-docker:v0.9.58
Error response from daemon: manifest unknown

@karlatec sorry! It's done now :)

Lost the finger on the pulse here. Sorry about that. However, @karlatec it's up now. Can you check that it works as expected?

[karlatec]

Gracias! Can confirm that overriding with --config works in new version.
