Struct cage::DefaultTags

pub struct DefaultTags { /* fields omitted */ }

This is typically used to incorporate image tags for specific builds generated by a continuous integration system (such as Go).

The on-disk format is a text file with one tagged image name per line:

example.com/app1:30
example.com/app2:57
alpine:4.3

The tags from this file will be used as default tags for these images. So for example, example.com/app1 would default to example.com/app1:30, and alpine would default to alpine:4.3.

Methods
