### Installation
|
|

|
|
|
|
## Syntax
|
|
|
|
A `docker_container` resource block declares the configuration data to be tested:
|
|
|
|
describe docker_container('container') do
|
|
it { should exist }
|
|
it { should be_running }
|
|
its('id') { should_not eq '' }
|
|
its('image') { should eq 'busybox:latest' }
|
|
its('repo') { should eq 'busybox' }
|
|
its('tag') { should eq 'latest' }
|
|
its('ports') { should eq [] }
|
|
its('command') { should eq 'nc -ll -p 1234 -e /bin/cat' }
|
|
end
|
|
|
|
<br>
|
|
|
|
## Resource Parameter Examples
|
|
|
|

it { should exist }
|
|
it { should be_running }
|
|
end
|
|
|
|
### id

describe docker_container(id: '71b5df59442b') do

|
it { should exist }
|
|
it { should be_running }
