Virtual-environments: Incorrect version

[trajano]

Description

https://github.com/actions/virtual-environments/blob/main/images/linux/Ubuntu1804-README.md

states that it is using Docker Compose (docker-compose version 1.26.2, build eefe0d31)

However, when I did docker-compose --version I got

docker-compose version 1.27.0, build 980ec85b

Area for Triage:

Question, Bug, or Feature?:

Bug

Virtual environments affected

• [ ] macOS 10.15
• [ ] Ubuntu 16.04 LTS
• [X] Ubuntu 18.04 LTS
• [X] Ubuntu 20.04 LTS
• [ ] Windows Server 2016 R2
• [ ] Windows Server 2019

Expected behavior

The versions match the documentation

Actual behavior

The versions do not match the documentation. In addition, there appears to be a bug in 1.27 which prevents docker-compose config from exiting 0 with no message causing the build scripts to fail.

Hi @trajano!
We've been updating Ubuntu 18 environments with the new VM image since Wednesday and plan to finish on Monday. The new readmes are available here, they will be automatically merged into the main branch when the deployment is finished
https://github.com/actions/virtual-environments/blob/releases/ubuntu18/20200908/images/linux/Ubuntu1804-README.md
https://github.com/actions/virtual-environments/blob/releases/ubuntu20/20200908/images/linux/Ubuntu2004-README.md

As a workaround you can update to 1.27.2 until we roll out the new image with this version:

URL="https://github.com/docker/compose/releases/download/1.27.2/docker-compose-Linux-x86_64"
sudo curl -L $URL -o /usr/local/bin/docker-compose
docker compose -v

Thanks, in my case I have to use

          - bash: |
              URL="https://github.com/docker/compose/releases/download/1.26.2/docker-compose-Linux-x86_64"
              sudo curl -L $URL -o /usr/local/bin/docker-compose
              docker-compose version
            displayName: Fix docker-compose version

since the upgrade to 1.27.x is causing the issue

I'm going to close the issue since we can't do much with compose bugs. Feel free to reopen it if you have any concerns.
Thank you!
