Docker Best Practices

Docker way

Docker has some restrictions and requirements depending on the architecture of your system (applications that you pack into containers). You can ignore these requirements or find some workarounds, but in this case, you won't get all the benefits from using Docker. My strong advice is to follow these recommendations:

• 1 application = 1 container
• Run process in foreground (don't use systemd, upstart or any other similar tools)
• Keep data out of container — use volumes
• Do not use SSH (if you need to step into container you can use docker exec command)
• Avoid manual configurations (or actions) inside container
