Uninstall

Back up first

Before uninstalling, save:

• /opt/pier/data/pier.db — the SQLite database.
• /opt/pier/.env — the encryption key (PIER_SECRET). Without it, the database cannot be decrypted.
• /opt/pier/data/backups/ — any automated backups.

Remove Pier

sudo systemctl stop pier
sudo systemctl disable pier
sudo rm /etc/systemd/system/pier.service
sudo rm -rf /opt/pier
sudo systemctl daemon-reload

Clean up containers

Pier does not remove the Docker containers it created. If you want to wipe everything:

docker ps -a --filter "label=pier.service" --format "{{.Names}}" | xargs -r docker rm -f
docker volume ls --filter "label=pier.service" --format "{{.Name}}" | xargs -r docker volume rm
docker network rm pier-net
