docker_container: "Malformed version number string 23.0.6+azure-2"

[mietzen]

Describe the problem

I'm running a GitHub action and trying to execute the following inspec test:

describe docker_container('my-container') do
  it { should exist }
  it { should be_running }
end

Locally this runs fine, but on the github action worker the docker version string is: 23.0.6+azure-2
and inspec fails with: Malformed version number string 23.0.6+azure-2

Possible Solution

Mayby sanitize the version string from 23.0.6+azure-2 to 23.0.6 in inspec?

[clintoncwolfe]

You're saying that you have a container, whose version number is 23.0.6+azure-2? And when InSpec encounters it, it throws this error?

Could you paste the backtrace (add --debug if needed)?

[mietzen]

No its the docker executable version:

$ docker --version
Docker version 23.0.6+azure-2, build ef23cbc

Here is a example GitHub Action Workflow:

name: "Docker Version"

on:
  push:
  workflow_dispatch:

jobs:
  docker-version:
    runs-on: ubuntu-latest
    steps:
      - run: docker --version

Edit: I'll post the debug log later.

For reference this is the project I encountered the problem:
