What is Vaultwarden? is an alternative implementation of API written in Rust. It’s compatible with official Bitwarden clients and is a perfect choice for a self-hosted vault. Being written in Rust makes it lightweight, unlike the original Bitwarden which is written in C# and quite resource-heavy. Vaultwarden Bitwarden server Why Podman? Docker doesn’t work properly with systemd. The problem is that systemd doesn’t monitor a docker container but a docker client. It means if the container crashes but the client is running, the systemd will not restart the container. It’s caused by Dockers’ client-server architecture. There’s a workaround for it but using a native solution seems more reasonable. is an open-source, daemon-less, Linux-native tool to run containers. It was developed under standards and it works perfectly with systemd. Because of its daemon-less nature, it allows running containers under an arbitrary user. Podman OCI Install Podman I will show how to install podman in Ubuntu 20.10, for other distributions refer to : the official guide sudo apt update
sudo apt install podman Run Vaultwarden My normal setup includes the admin panel enabled and registration of new users disabled. To enable the admin panel we have to pass an environment variable. It is recommended to use a long random string for this value. We can generate it using the command: ADMIN_TOKEN openssl rand openssl rand -base64 48 One more thing to do before we run our vault is to create a data directory. In this directory Vaultwarden stores its config and database: sudo mkdir /vw-data Now everything is ready to run Vaultwarden: sudo podman pull vaultwarden/server:latest
sudo podman run -d --name vaultwarden.pod -e ADMIN_TOKEN=YOUR_RANDOM_TOKEN_GOES_HERE -v /vw-data/:/data/ -p 8000:80 vaultwarden/server:latest Create systemd service Create a service file under : /etc/systemd/system/vaultwarden.pod.service sudo touch /etc/systemd/system/vaultwarden.pod.service I like to have the suffix to differentiate native services from containerized services. .pod Put the following content to the service file: [Unit]
Description=Vaultwarden/Bitwarden Server (Rust Edition)
Documentation=https://github.com/dani-garcia/vaultwarden
Wants=syslog.service

[Service]
Restart=on-failure
ExecStart=/usr/bin/podman start -a vaultwarden.pod
ExecStop=/usr/bin/podman stop vaultwarden.pod

[Install]
WantedBy=multi-user.target Here are a few things worth pointing out: is instructing to only restart the service when it exits with non-zero code. It allows us to stop the service using the as well as the command. Restart=on-failure podman stop systemctl To store the container’s logs to syslog we have . The option instructs to attach the container’s STDOUT and STDERR. podman start -a -a is needed to start our container on system boot. The option basically means that the service should be started when all network services are up and the system is ready to accept logins. If you omit the option your service will start on boot. WantedBy multi-user.target WantedBy NOT The option tells that syslog should be started when our service is being started. However, it’s a weak requirement and the service will still start if syslog fails to start. In other words, we would like to have logs but it’s not mandatory for our service. Wants=syslog.service Reload the daemon: sudo systemctl daemon-reload And check the Vaultwarden status: sudo systemctl status vaultwarden.pod
