Docker dev environment doesn't allow command line commands

Question

I recently set up a magento2 dev environment with Docker as identified on magento.com. However after installing new extensions I cannot run setup:upgrade or static-content deploy. Is this because of an internal domain name not being set or a db connection issues? Below are my CLI errors.

[Zend_Db_Adapter_Exception]

Answer 1

You need access your container using:

docker exec -ti CONTAINER_NAME bash

To discover the name use docker ps.
