title: Eclipse C++ Run blocked by Docker config with message "Docker Connection is missing or invalid"

  <p><em>Basic description:</em></p>
  <p>I have been having some troubles with Eclipse at every turn, it seems. After I build my code(with no issues), I run the program, and a config popup tells me that I'm missing a docker connection... to be entirely truthful, I'm not even that sure what a docker is/does. To my knowledge, I am not using a docker in any way.</p>

  <p><strong>sidenotes</strong></p>
  <p>-this happens for any program I attempt to run (hello world or anything)
  -I am not experienced with Eclipse, but I have run code without this issue</p>
