Hi,

I was trying to run some the Travis CI Build locally by using docker. I noticed that some worker instance cannot be found on the Dockerhub ([https://hub.docker.com/r/travisci/ci-garnet](https://hub.docker.com/r/travisci/ci-garnet))

Could you info me where to find the docker base images which are not on the Dockerhub?

Here here some examples:  
In [this job](https://travis-ci.org/Adobe-Consulting-Services/acs-aem-commons/jobs/538587343), under worker information, the instance “travis-ci-garnet-trusty-1512502259-986baf0” cannot found anywhere.

However,  
In [this job](https://travis-ci.org/Adobe-Consulting-Services/acs-aem-commons/jobs/463083587), under worker information, the instance “travisci/ci-garnet:packer-1512502276-986baf0” can be found.

Thanks!
