+
+Sometimes it's the little things in life. For example trying to
+connect to a MongoDB instance over and over again, without getting
+attached to a proper shell.
+
+```bash
+$ docker run --rm --net=host mongo mongo mydb
+MongoDB shell version: 3.2.7
+connecting to: mydb
+bye
+```
+
+So, before you end up like me – debugging things on the server side:
+Check your docker parameters. You might be missing a `-ti` argument to
+receive an interactive shell.
+
+``` bash
+$ docker run --rm -ti --net=host mongo mongo mydb
+MongoDB shell version: 3.2.7
+connecting to: mydb
+type "help" for help
+Welcome to the MongoDB shell.
+For interactive help, type "help".
