This is a maintenance release that was released due to a bug in Docker v2.1.0.0 which blocks UDP Traffic on ports lower than 1024 - docker/for-mac#3775. As soon as you update to Docker V2.1.0.0 you will need to update to pygmy v0.9.1.1 in order to get the local DNS resolution working. See Update procedure further down.
Bugfixes:
#42 - Fix non-working DNS resolver after a Docker v2.1.0.0 update
Improvements:
#37 - Improvements on pygmy update (Thanks to @fubarhouse!)
#39 - Documentation: HA Proxy information updated
#38 - Documentation: Added instruction to solve dnsmasq error in Ubuntu 18.04 and later
Update procedure:
Please see : https://pygmy.readthedocs.io/en/master/update/
After updating pygmy make sure you recreate the containers completely by running pygmy down and then pygmy up.
