unifi-controller

linuxserver/unifi-controller

The Unifi-controller software is a powerful, enterprise wireless software engine ideal for high-density client deployments requiring low latency and high uptime performance.

Supported Architectures

We utilise the docker manifest for multi-platform awareness. More information is available from docker here and our announcement here.

Simply pulling lscr.io/linuxserver/unifi-controller:latest should retrieve the correct image for your arch, but you can also pull specific arch images via tags.

The architectures supported by this image are:

Architecture	Available	Tag
x86-64	✅	amd64-<version tag>
arm64	✅	arm64v8-<version tag>
armhf	❌

Application Setup

The webui is at https://ip:8443, setup with the first run wizard.

For Unifi to adopt other devices, e.g. an Access Point, it is required to change the inform IP address. Because Unifi runs inside Docker by default it uses an IP address not accessible by other devices. To change this go to Settings > System Settings > Controller Configuration and set the Controller Hostname/IP to a hostname or IP address accessible by your devices. Additionally the checkbox "Override inform host with controller hostname/IP" has to be checked, so that devices can connect to the controller during adoption (devices use the inform-endpoint during adoption).

In order to manually adopt a device take these steps:

ssh ubnt@$AP-IP
set-inform http://$address:8080/inform

The default device password is ubnt. $address is the IP address of the host you are running this container on and $AP-IP is the Access Point IP address.

When using a Security Gateway (router) it could be that network connected devices are unable to obtain an ip address. This can be fixed by setting "DHCP Gateway IP", under Settings > Networks > network_name, to a correct (and accessable) ip address.

Strict reverse proxies

This image uses a self-signed certificate by default. This naturally means the scheme is https. If you are using a reverse proxy which validates certificates, you need to disable this check for the container.

Usage

To help you get started creating a container from this image you can either use docker-compose or the docker cli.

Parameters

Docker images are configured using parameters passed at runtime (such as those above). These parameters are separated by a colon and indicate <external>:<internal> respectively. For example, -p 8080:80 would expose port 80 from inside the container to be accessible from the host's IP on port 8080 outside the container.

Ports (-p)

Parameter	Function
8443	Unifi web admin port
3478/udp	Unifi STUN port
10001/udp	Required for AP discovery
8080	Required for device communication
1900/udp	Required for Make controller discoverable on L2 network option
8843	Unifi guest portal HTTPS redirect port
8880	Unifi guest portal HTTP redirect port
6789	For mobile throughput test
5514/udp	Remote syslog port

Environment Variables (-e)

Env	Function
PUID=1000	for UserID - see below for explanation
PGID=1000	for GroupID - see below for explanation
TZ=Europe/London	Specify a timezone to use (e.g. Europe/London) - see list
MEM_LIMIT=1024	Optionally change the Java memory limit (in Megabytes). Set to default to reset to default
MEM_STARTUP=1024	Optionally change the Java initial/minimum memory (in Megabytes). Set to default to reset to default

Volume Mappings (-v)

Volume	Function
/config	All Unifi data stored here

Miscellaneous Options

Parameter	Function

Environment variables from files (Docker secrets)

You can set any environment variable from a file by using a special prepend FILE__.

As an example:

-e FILE__PASSWORD=/run/secrets/mysecretpassword

Will set the environment variable PASSWORD based on the contents of the /run/secrets/mysecretpassword file.

Umask for running applications

For all of our images we provide the ability to override the default umask settings for services started within the containers using the optional -e UMASK=022 setting. Keep in mind umask is not chmod it subtracts from permissions based on it's value it does not add. Please read up here before asking for support.

User / Group Identifiers

When using volumes (-v flags), permissions issues can arise between the host OS and the container, we avoid this issue by allowing you to specify the user PUID and group PGID.

Ensure any volume directories on the host are owned by the same user you specify and any permissions issues will vanish like magic.

In this instance PUID=1000 and PGID=1000, to find yours use id user as below:

  $ id username
    uid=1000(dockeruser) gid=1000(dockergroup) groups=1000(dockergroup)

Docker Mods

We publish various Docker Mods to enable additional functionality within the containers. The list of Mods available for this image (if any) as well as universal mods that can be applied to any one of our images can be accessed via the dynamic badges above.
