title: "Docker Version"

description: "More information on why Docker version marks the installation as unsupported."

## The issue
|
|
|
|
The version that is needed by the Supervisor depends on the features it needs
|
|
to work properly.
|
|
|
|
The current minimum supported version of Docker is: `20.10.17`.
|
|
|
|
However, the feature set changes and improves over time. Therefore, the minimal
|
|
required version may change. When that happens, it will be communicated
|
|
before we publish a version that requires you to upgrade Docker.
|
|
|
|
## The solution
|
|
|
|
If you are running an older version of Home Assistant OS,
|
|
{% my updates title="update" %} it.
|
|
|
|
If this is not Home Assistant OS, you need to manually update Docker on your
|
|
host. For instructions on how to do that, check the official
|
|
[Docker documentation](https://docs.docker.com/engine/install/debian/).
