Develop OCI Client Library

[ishitasequeira]

Summary

As part of Argo CD OCI Integration, we would need to create a client library for supporting Argo CD interactions with OCI content using ORAS.

The library should include the support for the following functionalities:

• Creation/packaging
• Pushing
• Pulling
• Inspecting remote registries
• Extraction

The following capabilities should also be supported by the library:

• Authentication
• TLS Certificate handling (including disabling TLS verification)
  Support should also be available for associating Argo CD specific MediaType's to the content (such as application/vnd.cncf.argoproj.argocd.content.v1.tar+gzip/application/vnd.cncf.argoproj.argocd.config.v1+json)

The PR for the changes need to be raised targeting to oci-integration branch.

Feel free to join the Slack Channel #argo-cd-oci-integration for more discussions on OCI integration.

oras-go v2 can assist with the following functionalities:

• Creation/Packaging:
  • oras.PackManifest can be used to generate an OCI Image manifest.
• Pushing:
  • Consider copying artifacts from an OCI layout directory or the local file system to a remote repository.
• Pulling:
  • Similarly, artifacts can be copied from a remote repository to an OCI layout directory or the local file system.
• Inspecting Remote Registries:
  • The remote package provides an OCI-compliant SDK for interacting with remote registries.
• Authentication:
  • The auth package offers a configurable client for accessing remote registries.
• TLS Certificate Handling (including disabling TLS verification):
  • TLS certificates are supported through configuring auth.Client.

BTW, if you encounter any pain points in understanding/using oras-go v2, please let us know! We have an issue to track the documentation enhancement.

@ishitasequeira I also want to contribute to this task. Any followups or meetings I have to take up?

@nikzayn We are doing the work on the oci-integration branch for this feature. Also, we have the #argo-cd-oci-integration slack channel and working on building out the OCI Integration project to track progress.
