There may need to be modifications to the included example config files (`sentry/config.example.yml` and `sentry/sentry.conf.example.py`) to accommodate your needs or your environment (such as adding GitHub credentials). If you want to perform these, do them before you run the install script and copy them without the `.example` extensions in the name (such as `sentry/sentry.conf.py`) before running the `install.sh` script.
If you have any issues or questions, our [Community Forum](https://forum.sentry.io/c/on-premise) is at your service! Everytime you run the install script, it will generate a log file, `sentry_install_log-<ISO_TIMESTAMP>.txt` with the output. Sharing these logs would help people diagnose any issues you might be having.
We continously push the Docker image for each commit made into [Sentry](https://github.com/getsentry/sentry), and other services such as [Snuba](https://github.com/getsentry/snuba) or [Symbolicator](https://github.com/getsentry/symbolicator) to [our Docker Hub](https://hub.docker.com/u/getsentry) and tag the latest version on master as `:latest`. This is also usually what we have on sentry.io and what the install script uses. You can use a custom Sentry image, such as a modified version that you have built on your own, or simply a specific commit hash by setting the `SENTRY_IMAGE` environment variable to that image name before running `./install.sh`:
If you want to use different or specific images for other services, you may create a `docker-compose.overrides.yaml` file in the repo and override the `image` field for the corresponding services.
We strongly recommend keeping the `latest` tags for all, if you are using this repository directly. We also recommend using specific commit tags if you are consuming any of our Docker images in an environment that needs consistent deploys such as [a Helm chart](https://github.com/helm/charts/tree/master/stable/sentry).
Sentry comes with a cleanup cron job that prunes events older than `90 days` by default. If you want to change that, you can change the `SENTRY_EVENT_RETENTION_DAYS` environment variable in `.env` or simply override it in your environment. If you do not want the cleanup cron, you can remove the `sentry-cleanup` service from the `docker-compose.yml`file.
_You need to be on at least Sentry 9.1.2 to be able to upgrade automatically to the latest version. If you are not, upgrade to 9.1.2 first by checking out the [9.1.2 tag](https://github.com/getsentry/onpremise/tree/9.1.2) on this repo._
The included `install.sh` script is meant to be idempotent and to bring you to the latest version. What this means is you can and should run `install.sh` to upgrade to the latest version available. Remember that the output of the script will be stored in a log file, `sentry_install_log-<ISO_TIMESTAMP>.txt`, which you may share for diagnosis if anything goes wrong.
