10. Docker ‐ Produc on 10
11. Few ps before start Use some service to run containers eg. ECS, Docker Cloud, ... Use same image for development and production Don't mount code to containers in production If you need logs, send them from container Don't run databases in containers until you know what you're doing (you may loose all your data) Automate in small steps, not everything at once 11
12. Build and image docker-compose build app Building app Step 1/12 : FROM php:7.1-apache ... ... Step 11/12 : RUN composer install --prefer-dist --no-dev ---> Using cache ---> 9dddd2ab7071 Step 12/12 : RUN chmod -R 777 log temp ---> Using cache ---> f390380986e5 Successfully built f390380986e5 Successfully tagged ujovlado/posobota-91-docker:latest 12
13. Push the image docker login docker push ujovlado/posobota-91-docker:latest repository: docker.io/ujovlado/posobota-91-docker alternatives: Quay, AWS ECR, ... 13
