This document contains additional information on deploying dribdat to a web server.
The installation of dribdat on some cloud providers has been facilitated with quick-deploy scripts:
We have a (beta) Docker image available at https://hub.docker.com/r/loleg/dribdat
To deploy dribdat using a local Docker or Podman build, use the included
docker-compose.yml file as a starting point. This, by default, persists the PostgreSQL database outside the container, on the local filesystem in the
.db folder. For a first-time setup, perform the initial migrations as follows:
docker-compose run --rm dribdat ./release.sh
At this point you should be ready to start with Docker Compose:
docker-compose up -d
Optimize your dribdat instance with the following environment variables in production:
TIME_ZONE- set if your event is not in UTC time (e.g. "Europe/Zurich" - see pytz docs).
SERVER_URL- fully qualified domain name where the site is hosted.
DATABASE_URL- connects to PostgreSQL or another database via
postgresql://username:password@...(in Heroku this is set automatically)
DRIBDAT_SECRET- a long scary string for hashing your passwords - in Heroku this is set automatically.
DRIBDAT_ENV- 'dev' to enable debugging, 'prod' to optimise for production.
The following environment variables can be used to toggle application features:
DRIBDAT_CLOCK- use 'up' or 'down' to change the position, or 'off' to hide the countdown clock.
DRIBDAT_THEME- can be set to one of the Bootswatch themes.
DRIBDAT_STYLE- provide the address to a CSS stylesheet for custom global styles.
DRIBDAT_STAGE- provide the address to a YAML configuration for custom global stages.
DRIBDAT_APIKEY- a secret key for connecting bots with write access to the remote API.
DRIBDAT_USER_APPROVE- set to True so that any new non-SSO accounts are inactive until approved by an admin.
DRIBDAT_NOT_REGISTER- set to True to hide the registration, so new users can only join this server via SSO.
DRIBDAT_ALLOW_EVENTS- set to True to allow regular users to start new events, which admins can edit to make visible on the home page.
DRIBDAT_SOCIAL_LINKS- set to False to hide automatic social network links (Twitter etc.) on the site.
Support for Web analytics can be configured using one of the following variables:
ANALYTICS_GOOGLE(starts with "UA-...")
ANALYTICS_HREF- an optional link in the footer to a public dashboard for your analytics.
If you are required by law to use a cookie warning or banner, you can add this through your community code configuration.
If you would like people to be able to activate their accounts and reset passwords, you can connect to an SMTP mailing service (use Mailgun, or any other). Note that this is not really needed when you use OAuth (see next session) and disable registration completely.
MAIL_SERVER- just the domain name of your server.
MAIL_PORT- defaults to 25.
MAIL_USERNAME- the user name of your service.
MAIL_PASSWORD- the password to your service.
MAIL_DEFAULT_SENDER- a required reply-to address for e-mails.
MAIL_USE_TLS- require a secure (TLS) connection when talking to the SMTP server.
MAIL_USE_SSL- require a secure (SSL) connection when talking to the SMTP server.
OAuth 2.0 support for Single Sign-On (SSO) is currently available using Flask Dance, and requires SSL to be enabled (using
SERVER_SSL=1 in production or
OAUTHLIB_INSECURE_TRANSPORT in development). You may wish to disable non-SSO logins using
Register your app with the provider, and set the following variables:
OAUTH_TYPE- a supported provider: 'mattermost', 'slack', 'github', 'azure', 'auth0'
OAUTH_ID- the Client ID of your app.
OAUTH_SECRET- the Client Secret of your app.
OAUTH_DOMAIN- Slack subdomain, Auth0/Mattermost domain, or Azure tenant.
OAUTH_SKIP_LOGIN- (optional) users should go directly to external login screen.
OAUTH_LINK_REGISTER- (optional) a registration link to your SSO platform.
OAUTH_HELP_REGISTER- (optional) a short text for the login page.
You can find more advice in the Troubleshooting guide.
For uploading images and other files directly within dribdat, you can configure S3 through Amazon and compatible providers:
S3_KEY- the access key (20 characters, all caps)
S3_SECRET- the generated secret (long, mixed case)
S3_BUCKET- the name of your S3 bucket.
S3_REGION- defaults to 'eu-west-1'.
S3_FOLDER- skip unless you want to store to a subfolder.
S3_HTTPS- URL for web access to your bucket's public files.
S3_ENDPOINT- alternative endpoint for self-hosted Object Storage.
MAX_CONTENT_LENGTH- defaults to 1048576 bytes (1 MB) file size.
See example connection in the Troubleshooting guide.
Due to the use of the boto3 library for S3 support, there is a dependency on OpenSSL via awscrt. If you use these features, please note that the product includes cryptographic software written by Eric Young (email@example.com) and Tim Hudson (firstname.lastname@example.org).
These parameters can be used to improve the production setup:
SERVER_SSL- redirect all visitors to HTTPS, applying CSP rules.
SERVER_PROXY- set to True to use a standalone proxy and static files server - do not use if you already have a proxy set up.
SERVER_CORS- set to False to disable the CORS whitelist for external API access.
CSP_DIRECTIVES- configure content security policy - see Talisman docs.
CACHE_TYPE- speed up the site with Redis or Memcache - see Flask-Caching.
To customize some of the default content, you can edit the template include files in the folder
dribdat/templates/includes, for example you will find there the default quickstart.md and stages.yaml definitions. Make sure your changes will not be overwritten is you are using ephemeral storage (e.g. Heroku) for your deployment.
We encourage the use of Gunicorn to run the application in production. Here is an example with 4 workers:
gunicorn -w 4 -b 127.0.0.1:5000 "dribdat.app:init_app()"
A web proxy server is typically also used in production to optimize your deployment, add SSL certificates, etc. Here is an example configuration using nginx if you are running your application on port 5000:
