NOTE:

2019-08-15:

• Dropping -debian-nomongo tags from auto-build/Docker Hub. The cloud configuration with multiple tags per-build setup, and recreating build rules to change the latest version of each release makes it tedious to maintain. It will also improve build times. The Dockerfiles and setup for it will remain in the GitHub repo and can be built locally if needed/wanted.
• Version tags added. These will track the latest point release versions up to the time version is declared/released as stable by UI.
• Once a version is declared stable the version tag will track the last UI declared stable point release. If you need stable candidate, testing, etc. point releases for that version once it is stable you will need to target those specific tags.

Alpine and -nomongo tags DO NOT contain any internal MongoDB binaries. You must connect them to an external Mongo DB container or other host instance.

v5.9+: Ubiquiti changed the SSL certificate handling internally. If you're using a custom LetsEncrypt, etc. SSL certificate and upgrade to v5.9+ you will need to rename/remove the file unificert.sha256 in ./cert:/usr/lib/unifi/cert and restart the container to force a re-import of the existing certificate files under the changed keystore alias.

Additional info at https://community.ubnt.com/t5/UniFi-Beta-Blog/UniFi-5-9-4-Unstable-has-been-released/ba-p/2339206

v5.7+ discontinues support for the following hardware, if you have any of these devices in production you need to remain on v5.6:

• PicoM2 converted to UniFi
• UAP-AC
• UAP-AC v2
• UAP-AC-Outdoor

More information at https://community.ubnt.com/t5/UniFi-Updates-Blog/UniFi-5-7-20-Release-Update/ba-p/2278500

For security/attack surface reduction the container is configured to run the UniFi processes as an internal user & group unifi having a pre-set UID & GID of 999. The container will attempt to adjust permissions on mapped volumes and data to match before dropping privileges to start the UniFi Java and Mongo processes. If the container is being run with a different Docker --user setting permissions may need to be fixed manually.

IE: chown -R 999:999 ./{cert,data,logs}

A custom UID and GID can be configured for the container internal unifi user and group. For more information see the "Environment variables" section in this document.

ALWAYS MAKE A VERIFIED BACKUP OF DATA BEFORE INSTALLING UPDATES. Export a .unf from the web interface and/or stop the current container and create a backup or copy of the data volume. Database rollback from newer to older versions of UniFi and/or Mongo isn't always possible.

This container exposes three volumes:

• /usr/lib/unifi/cert - SSL custom certificate storage
• /usr/lib/unifi/data - UniFi configuration data and DBs
• /usr/lib/unifi/logs - UniFi and MongoDB logs for troubleshooting

This container exposes the following ports (see: https://help.ubnt.com/hc/en-us/articles/218506997-UniFi-Ports-Used):

• 3478/udp (port used for STUN connection)
• 6789/tcp (port used for throughput measurement from Android/iOS app)
• 8080/tcp (port for UAP/USW/USG to inform controller)
• 8443/tcp (port for controller GUI / API)
• 8880/tcp (port for HTTP portal redirect)
• 8843/tcp (port for HTTPS portal redirect)
• 10001/udp (port used for UBNT discovery broadcasts - Local LAN/L2/same subnet only)

The most basic way to run this container:

$ docker run --name unifi -d \
    -p 3478:3478/udp -p 8080:8080 -p 8443:8443 \
    -p 8880:8880 -p 8843:8843 \

Recommended run method: Docker Compose - UniFi app and Mongo DB as separate services:

version: '3'

services:
  mongo:
    image: mongo
    container_name: unifidb
    restart: unless-stopped
#   By default docker-compose will create a new bridge network for the services in the compose file.
#   Enable this to have the services/containers use the existing docker0/default bridge network.
#    network_mode: bridge
    volumes:
      - ./data/db:/data/db

  unifi:
    image: goofball222/unifi
    container_name: unifi
    restart: unless-stopped
#   By default docker-compose will create a new bridge network for the services in the compose file.
#   Enable this to have the services/containers use the existing docker0/default bridge network.
#    network_mode: bridge

Alternative network setup suggested by rogierlommers -

Please make sure to read the "NETWORK: HOST" section of the Docker "run" reference and understand the implications of this before using.

Copy the following to both services in the docker-compose.yml file under the commented out network_mode: bridge line in the example above, and then uncomment the network_mode: host line:

#   Use host network mode. Does not allow for port remapping. You may need to manually adjust
#       host firewall settings to allow traffic. Running a container in this mode is considered insecure.
#    network_mode: host

Example basic docker-compose.yml in file form.

Example advanced docker-compose.yml in file form with external Mongo DB service and UniFi service using environment variables.

Environment variables:

Recommended UniFi system.properties converted environment variables to externalize Mongo DB via docker-compose:

NB/IMPORTANT: Although I've been running my own deployments with an external DB for a year or more without issue with these settings externalizing the DB, just like running the app itself in a Docker container, is considered experimental and totally unsupported by UBNT. Full documentation for an external DB setup is outside the scope of this README and is left as an exercise for the interested reader. Additional information available on the UBNT forums in this post and in the PDF post linked below.

Additional UniFi system.properties config file settings can be passed to the container as -e/--env/environment flags at runtime (more detail and a PDF with UBNT examples here). Envrionment variables must be in ALL CAPS and replace "." with "_". -- IE:

SSL custom certificate auto-configuration support (LetsEncrypt, etc.):

1. Map the Docker host cert storage location or volume to the /usr/lib/unifi/cert volume exposed by the container
2. Must contain a PEM format SSL private key corresponding to the SSL certificate to be installed. Private key file MUST be named privkey.pem.
3. Must contain a PEM format SSL certificate file with the full certification chain. LetsEncrypt handles this automatically, other providers may need manual work (https://www.digicert.com/ssl-support/pem-ssl-creation.htm). Certificate file MUST be named fullchain.pem.
4. Start the container. SSL import and Java keystore update process is automated during startup. Status, errors, etc. can be found in the container log, IE: docker logs "containername"
5. Existing keystore file will be backed up to /usr/lib/unifi/data/keystore-"epochseconds"
6. Java keystore is only updated when changes to the certificate files are detected. To force a re-import of existing files delete the unificert.sha256 file in ./cert and restart the container.

If you don't want to use a custom SSL certificate then the /usr/lib/unifi/cert volume can be left unmapped. Alternatively if the privkey.pem and/or fullchain.pem file are not present SSL customization will be skipped.

To revert from a custom cert to a UniFi self-signed certificate stop the container, rename or remove ./data/keystore, and restart the container. The UniFi application will automatically generate a new keystore file with a new self-signed cert.

NOT RECOMMENDED FOR USE IN A PRODUCTION ENVIRONMENT - FOR TESTING/LABS ONLY

There have been past UniFi unstable/testing/stable candidate releases with AP bricking firmware, network breaking bugs, etc.

Proceed with caution! Use at your own risk.
