Could fedcloudclient interact with registry.egi.eu?

Initial checklist

• I read the support docs
• I read the contributing guide
• I agree to follow the code of conduct
• I searched issues and couldn’t find anything (or linked relevant results below)

Problem

Hi,

As proposed by @rosinec, it would be nice if fedcloudclient had some support to interact with https://registry.egi.eu/, e.g.

• list projects
• download and upload image/artefacts

Could this be considered?

Thanks!

Solution

Add the code to support the below commands:

# List projects in the registry
fedcloud registry --vo vo.name project list

# List repositories in the project
fedcloud registry --vo <name> --project <name> repository list

# List artefacts in the project/repository
fedcloud registry --vo <name> --project <name> --repository <name> artefact list

# Download artefacts
fedcloud registry --vo <name> --project <name> --repository <name> --artefact <name> artefact download

# Upload artefacts
fedcloud registry --vo <name> --project <name> --repository <name> --artefact <name> artefact upload

Alternatives

We are currently using: https://oras.land/

There is also https://github.com/goharbor/harbor-cli but at the moment this tool is experimental

Hello, I think it's great topic for some final thesis at university.
Give me some time to find someone who would appriciate work on this as thesis topic - I will report in a month.

For simplicity, we can split the new code into two modules:

• library module: a Python module registry.py with simple functions like project_list(token, vo), where token is OIDC access token for authentication and vo is the VO given as command-line parameter. Similarly functions repository_list(token, vo, project), artifact_list(token, vo, project, repository) and so on. All other parameters (e.g. registry endpoints) are defined as constant in the code or configuration file. CESNET, as the service provider, could develop it with or without dependency on fedcloudclient

• CLI module: that call the relevant functions from CLI

@rosinec what do you think

Alright, that makes sense.
