[BUG] otel-agent binary not present in Docker image

[nickvecelliooo]

Agent Environment
Initially found on 7.55.2, also tested on 7.55.3, latest, and 7-beta (the most recent push to dockerhub)

Describe what happened:
When otelCollector.enabled is set to true in the Helm chart, a container is added to the pod called otel-agent, with a command of

  command: ["otel-agent", "-foreground", "-config={{ template "datadog.otelconfPath" . }}/datadog.yaml"]

When the container tries to start, the following occurs:

    message: 'failed to create containerd task: failed to create shim task: OCI
      runtime create failed: runc create failed: unable to start container
      process: exec: "otel-agent": executable file not found in $PATH: unknown'

Describe what you expected:
The otel-agent binary to be present and the container to start

Steps to reproduce the issue:
Install the Datadog Helm chart with the below

datadog:
  apiKey: <yoink>
  clusterName: demo
  otelCollector:
    enabled: true

and the pod will not start.

This can also be tested in the images on dockerhub

$ docker run -it datadog/agent:7-beta bash
root@a5bfaa78b3f9:/# find / -name 'otel*'
/opt/entrypoints/otel-agent
root@a5bfaa78b3f9:/# cat /opt/entrypoints/otel-agent 
#!/usr/bin/env bash
set -euo pipefail

exec /opt/datadog-agent/embedded/bin/otel-agent --config /etc/datadog-agent/otel-config.yaml
root@a5bfaa78b3f9:/# /opt/datadog-agent/embedded/bin/otel-agent
bash: /opt/datadog-agent/embedded/bin/otel-agent: No such file or directory

I think this is because the feature is in beta:

You can find from this example in the helm repo : https://github.com/DataDog/helm-charts/blob/main/examples/datadog/agent_otel_collector.yaml that the image used is a not the latest one

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

When testing this image it seems to work

Hi team,

Do you have any update on this work? We are want to use the otel collector feature and waiting this issue.

Hey @sanglt sorry for the slow response. As mentioned above, the feature is indeed still in beta. There are several beta images available (you can identify them with the ot-beta suffix in the image tags). If you are interested in an extensive use of the feature, I would recommend you reach out to us to join the beta testing program.

Thank you!
