This is a simple docker based tool for creating Eth vanity addresses.
A vanity crypto-currency address is the same thing as a vanity car plate as in, an address wich you choose yourself (or at least the beginning part of it) as described on the StackExchange What is vanity address page.
Clone the repository in your main working directory in a folder like ~/ubuntu-node-vanityeth.
Build the docker image with:
docker build -t ubuntu-node-vanityeth .
And run it with (put your text at the end instead of 01):
docker run --rm ubuntu-node-vanityeth 01
Or just use the shell script and try: ./vanity.sh 01
In conclusion, if you run ./vanity.sh beef you will see how the new address starts with 0xbeef....
