Hi WickedGoat98
A few background notions:
Docker do not store their state, so if you install something inside a docker, the moment you leave, it is gone, and the next time you start the same docker you start from the same initial setup. (This is a great feature of Dockers) It seems the docker you are using is missing wget. You could build a new docker (see the Docker website for more details on how to use a Dockerfile). The way trains-agent works in dockers is it installs everything you need inside the docker. If for example you always want to have wget, or maybe even use it, you can tell trains-agent to run a specific set of bash commands when it sets up the docker. See here: https://github.com/allegroai/trains-agent/blob/216b3e21790659467007957d26172698fd74e075/trains_agent/backend_api/config/default/agent.conf#L147
