3. 1.
Docker like any other
Software has bugs
Keep it in mind to do good night's sleep

4. Reduce Image Size
Less is More
< Layer
= Base Image
One process per container
Whenever possible build “FROM scratch”
Avoid installing unnecessary packages
.dockerignore = < build time

image/dockerfile_best-practices/

5. Logs
Less is More, Once Again
Care taken with --log-drive
With json-file set max-size=[0-9+][k|m|g] and max-file=[0-9+]
https://docs.docker.com/engine/admin/logging/overview/

6. Bonus
Whenever possible use “--net=host”
Avoid Docker Compose to deploy your apps in production
Ulimit? Change the ulimit settings on the host

Deny developer make “docker push”
