Sentry: Install, Backup and Re-Install

Requirements

According to the official documentation, the minimum requirements for Sentry 24.x are 2 CPU cores / 4 GB RAM.

My tests show that Sentry 24.x runs on the following Hetzner VPS configurations:

Provider	Server	CPU cores	RAM	SWAP
Hetzner	CPX21	3	4 GB	7+ GB
Hetzner	CX31	2	8 GB	3+ GB
Hetzner	CPX41	4	16 GB
Contabo	VPS 1	4	6 GB	5+ GB

Additional requirements are Docker Engine and optionally reverse proxy.

Before re-install

Backup config files

• sentry/config.yml
• sentry/sentry.conf.py
• sentry/enhance-image.sh
• geoip/GeoIP.conf
• .env.custom

Backup settings

e.g. to file sentry/backup.json by following command:

./sentry-admin.sh export global /etc/sentry/backup.json

You may not have permission to create this file, then you can create it yourself and grant write permissions.

Docs: Backup & Restore

Before install

Follow the official installation documentation, but before running install.sh make sure you have the following files in the correct places:

Important config files

• sentry/config.yml configured from sentry/config.example.yml.
• sentry/sentry.conf.py configured from sentry/sentry.conf.example.py.

When restoring settings

• sentry/backup.json if you want to restore the Sentry Configuration from backup.

Additional config files

• sentry/enhance-image.sh configured from sentry/enhance-image.example.sh.
• geoip/GeoIP.conf configured from documentation.

After install

If you want to restore the Sentry Configuration, answer the following question with n and follow the steps below:

Would you like to create a user account now? [Y/n]: n

./sentry-admin.sh import global /etc/sentry/backup.json

Proceeding with this operation will irrecoverably delete all existing
low-volume data - are you sure want to continue? [y/n]: y

Starting up

docker compose up -d

Side Notes

--no-report-self-hosted-issues

Set env variable in file /etc/environment:

REPORT_SELF_HOSTED_ISSUES=0

To avoid reporting error and performance data for your Sentry instance.
