Docker & Docker Compose notes

prevent a ubuntu container in Docker Compose from stop

Running a ubuntu container in background using docker compose

# So if you want to keep your ubuntu container alive and don't want to attach it to a terminal, you'll have to use a process that will stay alive for as long as you want.
# Below is an example with sleep infinity as your main process

version: "3"
services:
  ubuntu:
    container_name: ubuntu
    image: ubuntu
    restart: on-failure
    command: ["sleep","infinity"]

learning Docker Compose

After gaining an understanding of some basic concepts, I realize that different Compose file version has different feature, so I tend to start from latest version as Compose file format 3.9 at 2022.12.13.
