SFTP_PASS=testpass
SFTP_PORT=2222

Then restart: docker compose up -d

./setup.sh
ssh-keygen -R "[localhost]:2222"  # Clear old host key from known_hosts
docker compose up -d

Stop / Clean Up

# Stop the server
docker compose down

docker compose down -v
rm -rf keys/ data/
ssh-keygen -R "[localhost]:2222"
./setup.sh
