Where Are the Docker Startup Options (Raspberry Pi Host)

This is very basic question, but I don’t know what I’m doing yet :slight_smile: All of the containers I have running are from other sources, I’ve yet to make one myself. I’m wanting to add a new volume to one of my containers.

I see tutorials online that refer to docker-compose.yaml. I installed docker on my raspberry pi4 following a guide (I’m not sure which one worked now, so I can’t point to it). I have a docker-compose.yaml file in my /opt/ directory, but I’m not really sure if that is what is being used.

How can I verify which file is being used for the options when I boot up my system?

I looked at /lib/systemd/system/docker.service, but didn’t see anything that referred to a .yaml file.


I can sense a lot of confusion here…

What makes you think there would be a default location for a docker-compose.yml file that results in automated deployments?

At least the initial deployment of your compose file will be a manual execution of docker-compose up -d or docker-compose -f /path/to/your/compose.yml up -d. Depending on the restart policy you declared on your services in the compose file, the containers will or will not be automaticly restarted after a reboot.

May I suggest an excellent self paced training on docker?

Your sense is correct. I’m very much in the learning phases, so starting from the basics is good. I’ll look into that guide. Thanks for the tutorial link!
