My environment is using a 3 node Docker Swarm (all being managers) and I have a docker-compose.yaml that was created to deploy out to the Swarm. Inside my docker-compose.yaml I have two services being setup, one is a MySQL instance and the other is my custom Django App. What I am trying to do is twofold. One is that I need to mount a local directory (Example: /geofftest) into the container. This file does exist on the host/node/server and I am trying to mount it to a file that exists in the container (Example: /tmp). The second thing I am trying to do is create a persistent database folder so that our MySQL doesn’t get destroyed when the container exits.
My issue is that I am not able to get a local host file (something in this case /geofftest) to show inside the container. I have tried using both the long syntax and short syntax to create a “bind mount”.
Here is my docker-compose.yaml file:
version: '3.2'
services:
project_mysql:

MYSQL_USER: 'project'
MYSQL_PASSWORD: 'password1234'

Thanks for any assistance!
