Run Sentry on Dokku
Deploy your own instance of Sentry onto Dokku!
This project is a clone of the official bootstrap repository (getsentry/onpremise) with a few modifications for a seamless deploy to Dokku.
What you get
This repository will deploy Sentry 9.1. It has been tested with Dokku 0.10+.
Requirements
Upgrading
When upgrading to a newer version, e.g. 8.22 to 9.1.0, you just need to follow the following steps:
First get the newest version of this repository from GitHub and push it to you Dokku host:
git pull
git push dokku masterDuring the deploy, Dokku will run all commands that are necessary to upgrade the database to the newest version. You do not need to do anything else.
Setup
This will guide you through the set up of a new Sentry instance. Make sure to follow these steps one after another.
App and databases
First create a new Dokku app. We'll call it sentry.
dokku apps:create sentry
Next we create the databases needed by Sentry and link them.
dokku postgres:create sentry_postgres
dokku postgres:link sentry_postgres sentry
dokku redis:create sentry_redis
dokku redis:link sentry_redis sentry
dokku memcached:create sentry_memcached
dokku memcached:link sentry_memcached sentry
Configuration
Set a secret key
dokku config:set --no-restart sentry SENTRY_SECRET_KEY=$(echo `openssl rand -base64 64` | tr -d ' ')
Email settings
If you want to receive emails from sentry (notifications, activation mails), you need to set the following settings accordingly.
dokku config:set --no-restart sentry SENTRY_EMAIL_HOST=smtp.example.com
dokku config:set --no-restart sentry SENTRY_EMAIL_USER=<yourusername>
dokku config:set --no-restart sentry SENTRY_EMAIL_PASSWORD=<yourmailpassword>
dokku config:set --no-restart sentry SENTRY_EMAIL_PORT=25
dokku config:set --no-restart sentry [email protected]
dokku config:set --no-restart sentry SENTRY_EMAIL_USE_TLS=True
Persistent storage
To persists user uploads (e.g. avatars) between restarts, we create a folder on the host machine and tell Dokku to mount it to the app container.
sudo mkdir -p /var/lib/dokku/data/storage/sentry
sudo chown 32768:32768 /var/lib/dokku/data/storage/sentry
dokku storage:mount sentry /var/lib/dokku/data/storage/sentry:/var/lib/sentry/files
Domain setup
To get the routing working, we need to apply a few settings. First we set the domain.
dokku domains:set sentry sentry.example.com
The parent Dockerfile, provided by the sentry project, exposes port 9000 for
web requests. Dokku will set up this port for outside communication, as
explained in its
documentation.
Because we want Sentry to be available on the default port 80 (or 443 for
SSL), we need to fiddle around with the proxy settings.
First add the proxy mapping that sentry uses.
dokku proxy:ports-add sentry http:80:9000
Then, remove the proxy mapping added by Dokku.
dokku proxy:ports-remove sentry http:80:5000
If dokku proxy:report sentry shows more than one port mapping,
remove all port mappings except the added above.
Push Sentry to Dokku
Grabbing the repository
First clone this repository onto your machine.
Via SSH
git clone [email protected]:mimischi/dokku-sentry.git
Via HTTPS
git clone https://github.com/mimischi/dokku-sentry.git
Set up git remote
Now you need to set up your Dokku server as a remote.
git remote add dokku [email protected]:sentry
Push Sentry
Now we can push Sentry to Dokku (before moving on to the next part).
git push dokku master
SSL certificate
Last but not least, we can go an grab the SSL certificate from Let's Encrypt.
dokku config:set --no-restart sentry [email protected]
dokku config:set --no-restart sentry SENTRY_USE_SSL=True
dokku letsencrypt sentry
Create a user
Sentry is now up and running on your domain (https://sentry.example.com). Before you're able to use it, you need to create a user.
dokku run sentry sentry createuser
This will prompt you to enter an email, password and whether the user should be a superuser.
