There is now an official [uMap](https://hub.docker.com/r/umap/umap) image. There is now an official [uMap](https://hub.docker.com/r/umap/umap) image.
To run it with docker compose, use a `docker-compose.yml` like this: To run it with docker compose, create a `docker-compose.yml` like this:
_Sample docker-compose.yml_
```yaml ```yaml

services: services:
db: db:
image: postgis/postgis:14-3.3-alpine # check https://hub.docker.com/r/postgis/postgis to see available versions

environment: environment:
- DATABASE_URL=postgis://postgres@db/postgres - DATABASE_URL=postgis://postgres@db/postgres
- SECRET_KEY=some-long-and-weirdly-unrandom-secret-key - SITE_URL=https://localhost:8001/
- SITE_URL=https://umap.local/ - STATIC_ROOT=/srv/umap/static
- UMAP_ALLOW_ANONYMOUS=True - MEDIA_ROOT=/srv/umap/uploads
- DEBUG=1
volumes: volumes:
- data:/srv/umap/uploads - umap_userdata:/srv/umap/uploads
# FIX the path on the left, below, to your location
- /home/ubuntu/umap.conf:/etc/umap/umap.conf
restart: always
depends_on:
- db
volumes: volumes:
data: umap_userdata:
db: umap_db:
``` ```
next, create a basic settings file, named `umap.conf`` in the same directory.
You can use this example below and it will run, but you may want to look at the project sample config, using `wget https://raw.githubusercontent.com/umap-project/umap/master/umap/settings/local.py.sample -O /etc/umap/umap.conf` and modify as needed.
Make sure the settings in the docker-compose don't conflict with the sample config and vice-versa. In particular, remove the DATABASES section from the config file if useing the docker-compose file, or it will override the DATABASE_URL setting and things won't work.
_Sample umap.conf_
```python
"""
Example settings for docker quickstart:
Lots of stuff has been removed for simplicity
See https://umap-project.readthedocs.io/en/master/settings/
Things YOU need to change before launching:
- modify SECRET_KEY
"""
from umap.settings.base import * # pylint: disable=W0614,W0401
SECRET_KEY = '!!secretsecret!!'
INTERNAL_IPS = ('127.0.0.1', )
ALLOWED_HOSTS = ['*', ]
DEBUG = True
COMPRESS_ENABLED = True
COMPRESS_OFFLINE = True
LANGUAGE_CODE = 'en'
# Set to False if login into django account should not be possible. You can
# administer accounts in the admin interface.
ENABLE_ACCOUNT_LOGIN = True
AUTHENTICATION_BACKENDS = (

)
# Enables a banner letting users know this site is not for production use
UMAP_DEMO_SITE = True
# Whether to allow non authenticated people to create maps.
UMAP_ALLOW_ANONYMOUS = True
```
Some basic settings are available through env vars (see https://github.com/umap-project/umap/blob/master/umap/settings/base.py) and can be defined right in the docker-compose file,
but if you need more custom ones (like custom OAuth configuration), the easiest
way is to put them in a [settings file](settings.md) and mount it to `/etc/umap/umap.conf`.

#### Quick sidebar about docker and docker-compose
A multi-platform tutorial on [installing docker](https://docs.docker.com/get-docker/) and docker-compose is outside the scope of this howto, but if you are on a recent Ubuntu, this is all you need to install both:
```bash
sudo groupadd docker
sudo snap install docker
sudo usermod -aG docker $USER
# EXIT and log back in to pickup the docker group membership, then test with
docker run hello-world
```
Current versions of docker compose are integrated into the docker command and launch with `docker compose` (two words) -- older versions use a separate binary named `docker-compose`. Either one will work for this.
---
### Initial launch
Start the server with
```bash
docker compose up
```
... and let it run some initial setup until the output quiesces with a message about spawning uWSGI workers. Because there is a race between the time the app tries to connect to the DB and when the DB is actually ready, you might see a few exceptions/erros about 'psychopg' being unable to connect. This should sort itself out as the app retries.
### Create superuser ### Create superuser
With docker-compose, run `docker-compose run app /venv/bin/umap createsuperuser` Now you need to create your site superuser. Stop the server (Ctrl-C) and then type:
```bash
docker-compose run app /venv/bin/umap createsuperuser`
``````
Once that's done, you can relaunch your server with `docker compose up`
### Try It!
You should not ne able to brose to your uMap instance form a browser on your local system, by pointing your browser to ${SITE_URL} (see the docker-compose file, above.)
### Administration
To administer the site (add users, change map tiles, other customizations) log in as the root user you just created, then go to ${SITE_URL}/admin
### Custom settings
Some basic settings are available through env vars (see https://github.com/umap-project/umap/blob/master/umap/settings/base.py),
but if you need more custom ones (like custom OAuth configuration), the easiest
way is to push a [settings file](settings.md) to `/etc/umap/umap.conf`.
