We are currently solving the following issue within our repository. Here is the issue text:
--- BEGIN ISSUE ---
Env value of TOIL_DOCKER_REGISTRY is not honored in the docker image
When a docker image is build with a custom `TOIL_DOCKER_REGISTRY`, the built docker image still looks at `quay.io/ucsc_cgl` for pulling related images (e.g. `mtail`, `grafana`, etc). The fix is to put the actual registry in `version_template.py`.

15 """This script is a template for src/toil/version.py. Running it without arguments echoes all
16 globals, i.e. module attributes. Constant assignments will be echoed verbatim while callables
17 will be invoked and their result echoed as an assignment using the function name as the left-hand
18 side and the return value of the function as right-hand side. To prevent a module attribute from
19 being echoed, start or end the attribute name with an underscore. To print the value of a single
20 symbol, pass the name of that attribute to the script as a command line argument. You can also
21 import the expand_ function and invoke it directly with either no or exactly one argument."""
