docker file update for 6.7.2

Could we get a docker file bump for the 6.7.2 update?

@magna-z what's the process for publishing a new version? Maybe I can do it at the same time I do releases.

@tananaev,
In the current workflow, to build and publish a Docker image, you need to create (and not delete) a branch with the target version in the vX.X.X format in this repository and set target version in all Dockerfiles and README.md.
PR (as #155) is only needed for updating README.md in master branch.

I have returned from vacation and am already transferring the build of Docker images to the main repository. Wait for my PR.

@alrassia,
Done with #155 PR.
