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: environment: MYSQL_USER: 'project' MYSQL_PASSWORD: 'password1234' ports: - 3306:3306 image: 'mysql/mysql-server' tty: true stdin_open: true deploy: mode: replicated replicas: 1 restart_policy: condition: on-failure placement: constraints: - node.hostname == node1-dc1 healthcheck: test: ["CMD", "mysqladmin" ,"ping", "-h", "localhost"] interval: "5s" timeout: "1s" project_web: image: 'localhost:5123/project_web:0.1.5' tty: true stdin_open: true volumes: - type: bind source: /geofftest target: /tmp ports: - "8000:8000" depends_on: - project_mysql healthcheck: test: ["CMD-SHELL", "nc -z 127.0.0.1 8000 || exit 1"] interval: "5s" timeout: "1s" networks: projectnet: driver: overlay ipam: config: - subnet: 10.2.0.0/24
Thanks for any assistance!
