Hue Server

Run the image

Hue can run in one line via the docker command (but needs to be configured to point to a traditional database instead of Sqlite). To have a zero configuration start use kubernetes instead.

Docker

Directly boot the image:

docker run -it -p 8888:8888 gethue/hue:latest

Hue should then be up and running on your default Docker IP on the port 8888, so usually http://127.0.0.1:8888.

Docker Compose

Docker compose allows to start all the required services in one command line.

This will start a Hue server as well as a MySQL database by default. Only the MySQL interpreter is configured in tools/docker/hue/conf/hue-overrides.ini.

Assuming we have a local hue.ini as shown in the previous section:

cd tools/docker/hue

Edit conf/hue-overrides.ini and ucomment the MySql section in [[database]].

Then:

docker-compose up -d

And to stop:

docker-compose down

Note If http://127.0.0.1:8888 does not work, get the IP of the docker container with:

sudo docker ps
CONTAINER ID        IMAGE               COMMAND             CREATED             STATUS              PORTS                            NAMES
4064b02b42c9        gethue/hue          "./startup.sh"      About a minute ago   Up About a minute   0.0.0.0:8888->8888/tcp   awesome_wiles

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' 4064b02b42c9
172.17.0.2

So in our case http://172.17.0.2:8888.

Configuration

By default the Hue container is using tools/docker/hue/conf/hue-overrides.ini on top of desktop/conf/hue.ini which assumes localhost for all the data services and uses and embedded sqlite database that will error out.

The default ini is used for configuration at the image build time (e.g. which apps to always disable or certain settings like banner customization).

In order to be useful, configure Hue at runtime to point to external services. The simplified ini hue-overrides.ini can be edited before starting Hue via:

cd tools/docker/hue
cp conf/hue-overrides.ini hue.ini

Edit the database settings in hue.ini for one of these two databases. Do not forget to create a 'hue' database too.

Postgres

[desktop]
[[database]]
engine=postgresql_psycopg2
host=127.0.0.1
port=5432
user=hue
password=hue
name=hue

MySql

[desktop]
[[database]]
engine=mysql
host=127.0.0.1
port=3306
user=root
password=secret
name=hue

If you want to be able to query a database out of the box, update the connector interpreters accordingly, e.g.:

[notebook]

  # One entry for each type of snippet.
  [[interpreters]]
    # Define the name and how to connect and execute the language.
    # https://docs.gethue.com/administrator/configuration/editor/

    [[[mysql]]]
      name = MySQL
      interface=sqlalchemy
      ## https://docs.sqlalchemy.org/en/latest/dialects/mysql.html
      options='{"url": "mysql://root:secret@database:3306/hue"}'

Then start the Hue server:

docker run -it -p 8888:8888 -v $PWD/hue.ini:/usr/share/hue/desktop/conf/z-hue.ini gethue/hue

Note

If for example the database is pointing to your localhost, if using Docker on Linux just add the --network="host" parameter and the container will correctly point to it.

sudo docker run -it -p 8888:8888 -v $PWD/desktop/conf/pseudo-distributed.ini:/usr/share/hue/desktop/conf/z-hue.ini --network="host" gethue/hue

Get the docker image

Just pull the latest from the Internet or build it yourself from the Hue repository via the Dockerfile.

Pull the image from Docker Hub

docker pull gethue/hue:latest

Build the image

Directly from Github source:

docker build https://github.com/cloudera/hue.git#master -t hue -f tools/docker/hue/Dockerfile

Or from a cloned local Hue:

docker build . -t hue -f tools/docker/hue/Dockerfile

Note

Feel free to replace -t hue in all the commands by your own docker repository and image tag, e.g. gethue/hue:latest, docker-account/hue:4.5.0

Push the image to the container registry

push docker.io/gethue/hue:latest
