I was hoping to use the OtelCollector, so I added the following configuration. However, I noticed that the stable and beta releases do not include the OpenTelemetry binary.

While looking for related issues, I came across #28523, and as a workaround, I applied the following configuration:

agents:
  image:
    repository: datadog/agent-dev
    tag: nightly-ot-beta-main
    doNotCheckTag: true

Up until a few days ago, the deployment was working well with this setup.

However, after recently updating the datadog-agent, I noticed that nightly-ot-beta-main had also been updated. When I tried rolling back to a previous version that had been working correctly, I found that its SHA256 digest was no longer available.

I believe there might be two possible solutions to this issue:

1. Would it be possible to provide the SHA256 digest of a version where the OtelCollector functions correctly?
2. Could the otel-agent binary be included in the stable release?

Additionally, I would really appreciate any insights into when this issue might be addressed.

Thank you for your time and support!

Hi @pilab-gwon, the otel-agent is not GA at this time and is not shipped at this time in the stable builds. You should look for images tagged with the ot-beta suffix. What agent version are you working with? Maybe we can help you find a tag (including the sha256), that is suitable for you. The fact the old image you were using satisfactorily is no longer available is somewhat surprising - I'll try to look into what might've happened there.

As for your point (2) made, we are still currently working on the beta to help address small issues and incorporate feedback such that the otel-agent can be deemed stable.
