- Repeatable builds takes discipline to pin versions
- Your immutable image isn’t as immutable when it’s running!
- Certain actions may double your container size!
- Fat Jars may not be container image friendly
- The differences between the popular Maven Docker plugins
- How to tag your images with the plugin and store metadata in the container itself
- Why did your disk run out of space?
Join this session to learn how to best address these issues when building your Java container images.
