#043 /dev/night - Optimizing Docker Builds

Are you using Docker images for deploying your apps?
​
AWS services like ECS and EKS needs lean builds(can make the process slower). On the other side, CI/CD and local development need faster builds(can get output bulky).
​
In this talk, Naren will show you a few strategies for optimizing your docker builds against time and size. You will see with various examples of possible optimizations and trade-offs.
​
Theme:

1. To show what impacts time and size while building a Docker image
2. How to optimize for time?
3. How to optimize for size?
4. Can we achieve both 2 & 3?
   ​
   Agenda:
   -------

• Choosing the right base image (Slim, Alpine, etc.)
• Build time. vs run time dependencies
• Importance of Docker layers
• Multi-stage building
• Using squid proxy for caching the re-installable packages
• Digging deep for junk in images
  ​
  The final example: Deploying a Django application with Wheel(No eggs) and multi-stage builds.

We will also livestream the event!
