The below test passes if the container ubuntu-container exists, is running, and the properties value matches against the desired value.

  describe lxc("ubuntu-container") do
    it { should exist }
    it { should be_running }
    its("name") { should eq "ubuntu-container" }
    its("status") { should cmp "Running" }
    its("type") { should eq "container" }
    its("architecture") { should eq "x86_64" }
    its("pid") { should eq 1378 }
    its("created_at") { should eq "2022/08/16 12:07 UTC" }
