# IPv6-Support for Docker
|
|
|
|
## Docker on Linux and Docker-rootless
|
|
First of all upgrade your docker installation to v27.0.1 or higher.
|
|
1. Then edit `/etc/docker/daemon.json` (or `~/.config/docker/daemon.json` in case of docker-rootless), add the below json:
|
|
|
|
```json
|
|
{
|
|
"default-network-opts": {"bridge":{"com.docker.network.enable_ipv6":"true"}}
|
|
}
|
|
```
|
|
|
|
Save the file.
|
|
|
|
2. Reload the Docker configuration file.
|
|
|
|
```console
|
|
sudo systemctl restart docker
|
|
```
|
|
3. Make sure that ipv6 is enabled for the internal `nextcloud-aio` network by running `sudo docker network inspect nextcloud-aio | grep EnableIPv6`. On a new instance, this command should return that it did not find a network with this name. Then you can run `sudo docker network create nextcloud-aio` in order to create the network with ipv6-support. However if it finds the network and its value `EnableIPv6` is set to false, make sure to follow https://github.com/nextcloud/all-in-one/discussions/4989 in order to recreate the network and enable ipv6 for it.

|
|
## Docker Desktop (Windows and macOS)
|
|
First of all upgrade your docker desktop installation to v4.32.0 or higher.
|
|
Then, on Windows and macOS which use Docker Desktop, you need to go into the settings, and select `Docker Engine`. There you should see the currently used daemon.json file.
|
|
|
|
1. You need to now adjust this json file:
|
|
|
|
```
|
|
"default-network-opts": {"bridge":{"com.docker.network.enable_ipv6":"true"}}
|
|
```
|
|
|
|
2. Add these values to the json and make sure to keep the other currently values and that you don't see `Unexpected token in JSON at position ...` before attempting to restart by clicking on `Apply & restart`.
