Windows Offline Deployment | Bitwarden Help Center (2024)

Self-hostingInstall & Deploy Guides

This article will walk you through the procedure to install and deploy Bitwarden to your own Windows server in an offline or air-gapped environment. Please review Bitwarden software release support documentation.

ª - Docker Compose can be installed via Docker Desktop, which includes Engine and Compose. Install Docker Desktop for Engine and Compose.

During this setup, you must uncheck the Use WSL2 instead of Hyper-V (recommended) option.

Additionally, ensure the following requirements are met:

• Using a machine with internet access, you have downloaded the latest docker-stub.zip file from the Bitwarden Server repository's releases page and transferred this file to your server.

• An offline SMTP server is setup and active in your environment.

• (Optional) OpenSSL Windows binaries are installed and ready to use on your server. You may use a self-signed certificate instead of OpenSSL if you wish.

Running Bitwarden on a Windows Server requires use of nested virtualization. Please check your Hypervisor's documentation to find out if nested virtualization is supported and how to enable it.

By default, Bitwarden will be served through ports 80 (http) and 443 (https) on the host machine. Open these ports so that Bitwarden can be accessed from within and/or outside the network. You may opt to choose different ports during installation.

We recommend configuring a domain name with DNS records that point to your host machine (for example, bitwarden.example.com), especially if you are serving Bitwarden over the internet.

Open PowerShell and create a Bitwarden local user by running the following command:

Bash
PS C:\> $Password = Read-Host -AsSecureString

After running the above command, enter the desired password in the text input dialog. After specifying a password, run the following command:

Bash

As the newly created user, create a Bitwarden folder under C:\:

Bash
PS C:\> mkdir Bitwarden

Once you install Docker Desktop, navigate to Settings → Resources → File Sharing and add the created directory (C:\Bitwarden) to the Resources list. Select Apply & Restart to apply your changes.

We recommend logging in as the newly created user before completing all subsequent procedures in this document.

To configure your machine with the assets required for your Bitwarden server:

1. Create a new directory in C:\Bitwarden named bwdata and extract docker-stub.zip to it.

   Once unzipped, the bwdata directory will match what the docker-compose.yml file's volume mapping expects. You may, if you wish, change the location of these mappings on the host machine.

2. In bwdata\env\global.override.env, edit the following environment variables:

   • globalSettings__baseServiceUri__vault=: Enter the domain of your Bitwarden instance.

   • globalSettings__sqlServer__ConnectionString=: Replace the RANDOM_DATABASE_PASSWORD with a secure password for use in a later step.

   • globalSettings__identityServer__certificatePassword=: Set a secure certificate password for use in a later step.

   • globalSettings__internalIdentityKey=: Replace RANDOM_IDENTITY_KEY with a random alphanumeric string.

   • globalSettings__oidcIdentityClientKey=: Replace RANDOM_IDENTITY_KEY with a random alphanumeric string.

   • globalSettings__duo__aKey=: Replace RANDOM_DUO_AKEY with a random alphanumeric string.

   • globalSettings__installation__id=: Enter an installation id retrieved from https://bitwarden.com/host.

   • globalSettings__installation__key=: Enter an installation key retrieved from https://bitwarden.com/host.

   • globalSettings__pushRelayBaseUri=: This variable should be blank. See Configure Push Relay for more information.

     tip

     At this time, consider also setting values for all globalSettings__mail__smtp__ variables and for adminSettings__admins. Doing so will configure the SMTP mail server used to send invitations to new organization members and provision access to the System Administrator Portal.

     Learn more about environment variables.

3. Generate a identity.pfx certificate for the identity container. You can do using OpenSSL or using any tool to generate a self-signed certificate. If you're using OpenSSL, run the following commands:

   Bash
   openssl req -x509 -newkey rsa:4096 -sha256 -nodes -keyout identity.key -out identity.crt -subj "/CN=Bitwarden IdentityServer" -days 10950

   and

   Bash
   openssl pkcs12 -export -out ./identity/identity.pfx -inkey identity.key -in identity.crt -passout pass:IDENTITY_CERT_PASSWORD

   In the above command, replace IDENTITY_CERT_PASSWORD with the certificate password created and used in Step 2.

4. Move identity.pfx to the mapped volume directory (by default, .\bwdata\identity).

5. Copy identity.pfx to the .\bwdata\ssl directory.

6. Create a subdirectory in .\bwdata\ssl named for your domain.

7. Provider a trusted SSL certificate and private key in the newly created .\bwdata\ssl\bitwarden.example.com subdirectory.

   note

   This directory is mapped to the NGINX container at \etc\ssl. If you can't provide a trusted SSL certificate, front the installation with a proxy that provides an HTTPS endpoint to Bitwarden client applications.

8. In .\bwdata\nginx\default.conf:

   1. Replace all instances of bitwarden.example.com with your domain, including in the Content-Security-Policy header.

   2. Set the ssl_certificate and ssl_certificate_key variables to the paths of the certificate and private key provided in Step 6.

   3. Take one of the following actions, depending on your certificate setup:

      • If using a trusted SSL certificate, set the ssl_trusted_certificate variable to the path to your certificate.

      • If using a self-signed certificate, comment out the ssl_trusted_certificate variables.

9. In .\bwdata\env\mssql.override.env, replace RANDOM_DATABASE_PASSWORD with the password created in Step 2.

10. In .\bwdata\web\app-id.json, replace bitwarden.example.com with your domain.

To get docker images for use on your offline machine:

1. From an internet-connected machine, download all bitwarden/xxx:latest docker images, as listed in the docker-compose.yml file in docker-stub.zip.

2. Save each image to a .img file, for example:

   Bash
   docker image save -o mssql.img bitwarden/mssql:version

3. Transfer all .img files to your offline machine.

4. On your offline machine, load each .img file to create your local docker images, for example:

   Bash
   docker image load -i mssql.img

Start your Bitwarden server with the following command:

Bash
docker compose -f ./docker/docker-compose.yml up -d

Verify that all containers are running correctly:

Bash
docker ps

Congratulations! Bitwarden is now up and running at https://your.domain.com. Visit the web vault in your browser to confirm that it's working.

You may now register a new account and log in. You will need to have configured SMTP environment variables (see Environment Variables) in order to verify the email for your new account.

Updating a self-hosted server that has been installed and deployed manually is different from the standard update procedure. To update your manually-installed server:

1. Download the latest docker-stub.zip archive from the releases pages on GitHub.

2. Unzip the new docker-stub.zip archive and compare its contents with what's currently in your bwdata directory, copying anything new to the pre-existing files in bwdata.
   Do not overwrite your pre-existing bwdata directory with the contents of the newer docker-stub.zip archive, as this would overwrite any custom configuration work you've done.

3. Download the latest container images and transfer them to your offline machine as documented above.

4. Run the following command to restart your server with your updated configuration and the latest containers:

   Bash
   docker compose -f ./docker/docker-compose.yml down && docker compose -f ./docker/docker-compose.yml up -d
