* Docker provides a static binary which is useful to have in containers when |

15
|
|
|
* in the container itself docker should be available (e.g. docker service). |
|
16
|
|
|

|

|
|
|
* It "comes" out of this binary repository. In the background there is a |
|
18
|
|
|
* BinaryUnPackager taking care of network interaction and file verification |
|
19
|
|
|
* as it is technically possible to have different kind of static docker |
|
20
|
|
|
* binaries also from different packages. |
