Tips & Tricks for the week

Hard-coded ports in a docker compose file can cause issues when you try to start the container when something is already running on that port.

To get around this, don't hard-code the port in your docker-compose.yaml file:

services:
  adminer:
    image: adminer
    restart: always
    ports:
      - 8080:8080

Don't define a port, but let docker select a dynamic port for you.

services:
  adminer:
    image: adminer
    restart: always
    ports:
      - 8080

Then get the dynamic port from docker compose:

docker-compose port adminer 8080

Then you can open this URL in a browser.

What this week has in store

Now that I've added a few tools my everything bot I'm going to add a some MCP servers, such as Github, to see if they can speed up my development process.

See you next week!
