Docker-DNS-Name-Problem.md

IF Docker is not able to detect nodes based on their name when running on Ubuntu or differnt Linux distributions....

execute the following script:

sudo apt-get install bridge-utils
sudo pkill docker
sudo iptables -t nat -F
sudo ifconfig docker0 down
sudo brctl delbr docker0
sudo service docker restart

If ifconfig is not installed.

add it via

sudo apt install net-tools
