Subject: [PATCH] fix: correct handling of container retrieval

In the previous method, if the container was renamed or there were multiple names attached to the container, fetching the container ID would fail as the regex would only match at the end. Instead of using grep, use the docker 'filter' functionality to fetch the container ID as appropriate.
