[trivikr]

Describe the bug

make test shows "version" is obsolete warning

To Reproduce

Follow https://github.com/bluesky-social/atproto#developer-quickstart

Expected behavior

make test to not show any warning

WARN[0000] /Users/trivikram/workspace/atproto/packages/dev-infra/docker-compose.yaml: `version` is obsolete

Details

• Operating system: macOS 14.6.1 (23G93)
• Node version: v20.18.0
• Docker version: 27.0.3, build 7d4bcd8

Additional context

N/A

This is happening since Version top-level element (obsolete) is obsolete.

But it's defined in

atproto/packages/dev-infra/docker-compose.yaml

Line 1 in 3a5fc92

version: '3.8'

[trivikr]

The test failure seems to be for different reason, and I wrongly associated it with "version" is obsolete warning.
I renamed this issue to just the warning, and will create new one for failure. The bug label can be removed.
