Hi @esigo. Thanks for your PR.

I'm waiting for a kubernetes member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.

Looks good to me, @longwuyuan wdyt? If tested and works fine we can approve it :D

[longwuyuan]

@rikatz :-) this is 100% good to merge. FYI, there is history here. I created a issue in the Opentelemetry project open-telemetry/opentelemetry-cpp-contrib#141 and @esigo is a maintainer at OT is actually going above and beyond to help solve the confusing problem we are having with running OT module in sidecar.

Thanks tons @esigo

@esigo You're great. If images works normally in the VM, can you push your docker image to the hub and provide it to me for download and test? thank

[esigo]

It seems I have used the wrong sha256 in this PR. I have to raise another one to fix the hash.

[longwuyuan]

@esigo , Please go ahead. Will wait for she fix.
@rikatz , this merge should have fired a cloud build for new OT image. But there is no new OT image even after 24 hours. Did I assume wrong.
