I am using Docker version 20.10.17, build 100c701, on Ubuntu 20.04.4.
I have successfully created a jenkins/jenkins:lts image with its own volume, using the following command:
docker run -p 8082:8080 -p 50001:50000 -d -v jenkins_home:/var/jenkins_home jenkins/jenkins:lts
But after installing many plugins and running many jobs on Jenkins, I kept getting a notification on the Jenkins GUI that the storage is almost full (it was almost 388 Mb).
1- What is the default size of a docker volume ? I couldn’t find an answer anywhere.
2- I tried to specify the size of the volume (after deleting everything image/container/volume) using the driver_opts and using a docker compose file.
The docker-compose.yml file.
version: '3' services: jenkins: build: context: . dockerfile: ./Dockerfile volumes: - /var/run/docker.sock:/var/run/docker.sock - jenkins_home:/var/jenkins_home ports: - 8082:8080 - 50001:50000 volumes: jenkins_home: driver_opts: o: "size=900m"

I got an error that the required device option is not specified.
I don’t want a temporary storage tmpfs, so i tried to specify a path on my machine. I got the error that there is no such device.
What am I doing wrong? How should I proceed?
My final target is to create a Jenkins container that has a large volume size.
