How to setup sentry with docker - docker

Question

I have found the official sentry image in dockerhub. But the document is incomplete and I can't setup the environment step by step.
We have to setup the database container first but none of them tell how to setup it at first. Specifically I don't know what are the username and password that sentry will use.
And I also get the following error when I run the sentry container:
sudo docker run --name some-sentry --link some-mysql:mysql -d sentry
e888fcf2976a9ce90f80b28bb4c822c07f7e0235e3980e2a33ea7ddeb0ff18ce
sudo docker logs some-sentry
Traceback (most recent call last):

UPDATE circa version 21
They don't seem to want to build the official image for us any more as per the deprecation notice on Docker Hub. However, good news, in https://develop.sentry.dev/self-hosted/#getting-started
They supply an install script
There is an official docker-compose included
Seems Kafka and Zookeeper are now required too. Follow the docs to stay up to date.
This is a moving target. I suggest checking https://hub.docker.com/_/sentry/ for updates as their documentation is pretty good.
Circa version 8 you can easily convert those instructions to use docker-compose
docker-compose.yml
version: "2"
services:
redis:
image: redis:3.0.7
networks:
- sentry-net
postgres:
image: postgres:9.6.1
environment:
- POSTGRES_USER:sentry
- POSTGRES_PASSWORD:sentry
# volumes:
# - ./data:/var/lib/postgresql/data:rw
networks:
- sentry-net
sentry:
image: sentry:${SENTRY_TAG}
depends_on:
- redis
- postgres
environment:
- SENTRY_REDIS_HOST=redis
- SENTRY_SECRET_KEY=${SECRET}
- SENTRY_POSTGRES_HOST=postgres
ports:
- 9000:9000
networks:
- sentry-net
sentry_celery_beat:
image: sentry:${SENTRY_TAG}
depends_on:
- sentry
environment:
- SENTRY_REDIS_HOST=redis
- SENTRY_SECRET_KEY=${SECRET}
- SENTRY_POSTGRES_HOST=postgres
command: "sentry run cron"
networks:
- sentry-net
sentry_celery_worker:
image: sentry:${SENTRY_TAG}
depends_on:
- sentry
environment:
- SENTRY_REDIS_HOST=redis
- SENTRY_SECRET_KEY=${SECRET}
- SENTRY_POSTGRES_HOST=postgres
command: "sentry run worker"
networks:
- sentry-net
networks:
sentry-net:
.env
SENTRY_TAG=8.10.0
Run docker run --rm sentry:8.10.0 config generate-secret-key and add the secret
.env updated
SENTRY_TAG=8.10.0
SECRET=somelongsecretgeneratedbythetool
First boot:
docker-compose up -d postgres
docker-compose up -d redis
docker-compose run sentry sentry upgrade
Full boot
docker-compose up -d
Debug
docker-compose ps
docker-compose logs --tail=10

Answer 2

Take a look at the sentry.conf.py file that is part of the official sentry docker image. It gets a bunch of properties from the environment e.g. SENTRY_DB_NAME, SENTRY_DB_USER. Below is an excerpt from the file.
os.getenv('SENTRY_DB_PASSWORD')
or os.getenv('MYSQL_ENV_MYSQL_PASSWORD')
or os.getenv('MYSQL_ENV_MYSQL_ROOT_PASSWORD')
So as for your question about how to sepcify database password it must be set in environment variables. You can do this by running:
sudo docker run --name some-sentry --link some-mysql:mysql \
-e SENTRY_DB_USER=XXX \
-e SENTRY_DB_PASSWORD=XXX \
-d sentry
As for your issue with the exception you seem to be missing a config file Configuration file does not exist at '/.sentry/sentry.conf.py' That file is copied to /home/user/.sentry/sentry.conf.py inside the container. I am not sure why your sentry install is looking for it at /.sentry/sentry.conf.py. There may be an environment variable or a setting that controls this or this may just be a bug in the container.

This works for me https://github.com/slafs/sentry-docker and we don't have to setup database or others. I will learn more about the configuration in detail later.

Answer 4

Here my docker compose yml, with official image from https://hub.docker.com/_/sentry/:
https://gist.github.com/ebuildy/270f4ef3abd41e1490c1
Run:
docker-compose -p sw up -d
docker exec -ti sw_sentry_1 sentry upgrade
Thats it!
