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.
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.
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.
