I don't think there are many blind programmer communities out there. I know of an attempt to create /r/BlindDevelopers here on reddit but that's essentially dead, and the
$1 at audiogames.net. I'm a programmer myself, though I don't do it professionally anymore since I'm still trying to find my niche as a blind programmer.
Right now I find comfort with TextMate 2 and the Terminal on MacOS, as well as Xcode for iOS and MacOS development. Despite being totally blind I don't use Braille, relying entirely on the speech synthesizer instead, as I struggle reading Braille to the point that it is a lot more functional to just move the caret and make the screen-reader read character by character. However this is one subject on which there doesn't seem to exist a consensus in the blind community, because adapting to new environments is so difficult and requires such an investment of time that people tend to stick to what they already feel comfortable with.
Regarding Docker I use it in the command-line and work on a bind mount so that I can use TextMate 2 and git on the host for development while installing all the dependencies that I need inside disposable containers.
