Install explicit version and use tags #1
Description
Add the version to the install command (e.g. apt-get install cura=1:3.3.1~201806260909~rev3015~pkg252~ubuntu18.10.1) and upload the docker image with version tag (e.g. stevebake/cura-docker:3.3.1). This way you are able to use a previous version of the cura docker image, if you want to.
