This changes the effective license from a simple Apache-2.0 license to a dual license consisting of both Apache-2.0 and the MIT license to be more compatible for use in GPL Code. The MIT license requires reproducing countless copies of the same copyright header with diffferent names in the copyright field, for every MIT library in use. The Apache license does not have this drawback. However, this is not the primary motivation for creating these issues. The Apache license also has protections from patent trolls and explicit contribuition licensing clause. However the Apache license is incompatible with GPLv2. This is why Rust is dual-licensed as MIT/Apache (the "primary" license being Apache, MIT only for GPLv2 compat), and doing so would be wise for this project. This also makes this crate suitable for inclusion and unrestricted sharing in the Rust standard distribution and other projects using dual MIT/Apache.

|
### Deleteing a tagged image
|
|
|
|
Delete a tagged image from the registry
|
|
|
|
Note! This requires that the registry has storage delete rights enabled. For
|
|
example, when creating the registry, setting the environment variable
|
|
`REGISTRY_STORAGE_DELETE_ENABLED=true` to enable that feature. If that is not
|
|
enabled, a `MethodNotAllowed` error will be returned.
|
|
|
|
Note! This will only remove the tag from the registry, it will not remove
|
|
orphaned digests. For that, the garbage collector on the registry service must
|
|
be run separately.
|
|
|
|
```shell
|
|
Usage: dredge <REGISTRY> delete <IMAGE> <TAG>
|
|
|
|
Arguments:
|
|
<IMAGE>
|
|
<TAG>
|
|
|
|
Options:
|
|
-h, --help Print help
