What is Sentry?

Sentry is a realtime event logging and aggregation platform. It specializes in monitoring errors and extracting all the information needed to do a proper post-mortem without any of the hassle of the standard user feedback loop.

How to use this image

How to setup a full Sentry instance

  1. Start a Redis container

                    $ docker run -d --name sentry-redis redis
  2. Start a Postgres container

                    $ docker run -d --name sentry-postgres -e POSTGRES_PASSWORD=secret -e POSTGRES_USER=sentry postgres
  3. Generate a new secret key to be shared by all sentry containers. This value will then be used as the SENTRY_SECRET_KEY environment variable.

                    $ docker run --rm sentry config generate-secret-key
  4. If this is a new database, you’ll need to run upgrade

                    $ docker run -it --rm -e SENTRY_SECRET_KEY='<secret-key>' --link sentry-postgres:postgres --link sentry-redis:redis sentry upgrade

    Note: the -it is important as the initial upgrade will prompt to create an initial user and will fail without it

  5. Now start up Sentry server

                    $ docker run -d --name my-sentry -e SENTRY_SECRET_KEY='<secret-key>' --link sentry-redis:redis --link sentry-postgres:postgres sentry
  6. The default config needs a celery beat and celery workers, start as many workers as you need (each with a unique name)

                    $ docker run -d --name sentry-cron -e SENTRY_SECRET_KEY='<secret-key>' --link sentry-postgres:postgres --link sentry-redis:redis sentry run cron
    $ docker run -d --name sentry-worker-1 -e SENTRY_SECRET_KEY='<secret-key>' --link sentry-postgres:postgres --link sentry-redis:redis sentry run worker

Port mapping

If you’d like to be able to access the instance from the host without the container’s IP, standard port mappings can be used. Just add -p 8080:9000 to the docker run arguments and then access either http://localhost:8080 or http://host-ip:8080 in a browser.

Configuring the initial user

If you did not create a superuser during upgrade, use the following to create one:

        $ docker run -it --rm -e SENTRY_SECRET_KEY='<secret-key>' --link sentry-redis:redis --link sentry-postgres:postgres sentry createuser


Environment variables

When you start the sentry image, you can adjust the configuration of the Sentry instance by passing one or more environment variables on the docker run command line. Please note that these environment variables are provided as a jump start, and it’s highly recommended to either mount in your own config file or utilize the sentry:onbuild variant.


A secret key used for cryptographic functions within Sentry. This key should be unique and consistent across all running instances. You can generate a new secret key doing something like:

        $ docker run --rm sentry config generate-secret-key



Database credentials for your Postgres server. These values aren’t needed if a linked postgres container exists.


Connection information for your Redis server. These values aren’t needed if a linked redis container exists.


Connection information for a Memcache server. These values aren’t needed if a linked memcached container exists.


Directory where uploaded files will be stored. This defaults to /var/lib/sentry/files and is a VOLUME for persistent data.


The email address used for From: in outbound emails. Default: root@localhost


Connection information for an outbound smtp server. These values aren’t needed if a linked smtp container exists.


If you’re using Mailgun for inbound mail, set your API key and configure a route to forward to /api/hooks/mailgun/inbound/.

Image Variants

The sentry images come in many flavors, each designed for a specific use case.


This is the defacto image. If you are unsure about what your needs are, you probably want to use this one. It is designed to be used both as a throw away container (mount your source code and start the container to start your app), as well as the base to build other images off of.


This image makes it easy to custom build your own Sentry instance by copying in a custom config.yml and/or file and installing plugins from requirements.txt.

It’s also possible to develop custom extensions within your onbuild package. If the build directory contains a file, this will also get installed.

See the official Sentry documentation for more information.

To create your custom sentry:onbuild package, simply do the following:

  1. Create a Dockerfile containing FROM sentry:onbuild
  2. In the same directory, add your custom configuration files.
  3. You can get copies of those files to use as templates from the docker-sentry GitHub repo.
  4. Build your image: docker build -t mysentry .
  5. Run your custom image using mysentry instead of sentry.
