Description: `
|
|
This command is used to specify a new tag for a recipe. These tags are used to
|
|
identify different versions of the recipe and are published on the Co-op Cloud
|
|
recipe catalogue.
|
|
|
|
These tags take the following form:
|
|
|
|
a.b.c+x.y.z
|
|
|
|
Where the "a.b.c" part is maintained as a semantic version of the recipe by the
|
|
recipe maintainer. And the "x.y.z" part is the image tag of the recipe "app"
|
|
service (the main container which contains the software to be used).
|
|
|
|
We maintain a semantic versioning scheme ("a.b.c") alongside the libre app
|
|
versioning scheme in order to maximise the chances that the nature of recipe
|
|
updates are properly communicated.
|
|
|
|
Abra does its best to read the "a.b.c" version scheme and communicate what
|
|
action needs to be taken when performing different operations such as an update
|
|
or a rollback of an app.
