The docs state the Docker image is not maintained - https://developers.eos.io/eosio-home/v1.7.0/docs/introduction
The Docker image is no longer maintained has been deprecated. The eosio/eos image from Dockehub will be available until it's sunset on June 29 2018
I had seen before that docker should be used.
Is there an official recommendation from Block One about how to install EOSIO?
