Docker and Docker Distribution
Docker technologies have a fast iteration pace. This is a good thing, but it comes with some challenges. As requested by some of our users, the following table shows which versions of Docker and Docker Distribution are supported by each Portus version:
Portus | Docker Engine | Docker Distribution | CoreOS Clair |
---|---|---|---|
master | 1.6+ | 2.0+ | 2.0.x |
2.3.x | 1.6+ | 2.0+ | 2.0.x |
2.1.x & 2.2.x | 1.6+ | 2.0+ | - |
2.0.0 & 2.0.1 | 1.6 to 1.9 | 2.0 to 2.2 | - |
2.0.2 | 1.6 to 1.9 | 2.0 to 2.4 | - |
2.0.3+ | 1.6+ | 2.0 to 2.4 | - |
Let’s detail some of the versions being specified:
- Docker Engine
1.6
is the first version supported by Docker Distribution 2. Therefore, this requirement is also the same for Portus. - As of Docker
1.10
, the Manifest Version 2, Schema 2 is the one being used. This is only supported by Portus in themaster
branch and in2.0.3
. - Docker Distribution
2.3
supports both Manifest versions, but some changes had to be made in order to offer backwards compatibility. This is not supported neither for Portus2.0.0
nor2.0.1
. - CoreOS Clair has been supported as a security scanner since
2.3.0
