Integrating block-sync in an init-container #779

kushalShukla-web · 2024-11-08T16:46:07Z

Changes that are introduced in this pr , followed by Create a CLI for uploading and downloading blocks #760 .
Integrated download-key in an init container that downloads the key.yml file from the Prometheus repository. It uses the key.sh script to fetch the pull request and copy the key.yml file into the volumeMount section:

volumeMounts:
  - name: key
    mountPath: /config

Integrated data-downloaderon both pr and released side, which uses the block-sync binary to download pre-generated block data.
Updated the prometheus-builder image, modifying the builder.sh file to copy the key.yml file into the volumeMount section so that the PR section can also download the pre-generated block data.

I'm struggling to find my way around. Some trivial points stand out, but I need better orientation.

removed from block-sync:

Please explain each PR in terms of what it does, not what some other PR didn't do.

For example, you could describe the intended purpose of key.sh.

Could we instead tell people to create an empty Secret?

How would someone coming to this for the first time understand this choice?
Can we give some context why data might be downloaded?
