This page will show you how to set up a local Bitwarden server for development purposes.
The Bitwarden server is comprised of several services that can run independently. For a basic development setup, you will need the Api and Identity services.
:::info
Before you start: make sure you’ve installed the recommended Tools and Libraries, including:
- Docker Desktop
- Visual Studio 2022
- Powershell
- NET 6.0 SDK
- Azure Data Studio
:::
:::info
A guide for developing in VS Code Dev containers can be found here if you prefer developing in a containerized environment.
:::
-
Clone the Bitwarden Server project:
git clone https://github.com/bitwarden/server.git
-
Open a terminal and navigate to the root of the cloned repository.
-
Configure Git to ignore the Prettier revision:
git config blame.ignoreRevsFile .git-blame-ignore-revs
-
(Optional) Set up the pre-commit
dotnet formathook:git config --local core.hooksPath .git-hooks
Formatting requires a full build, which may be too slow to do every commit. As an alternative, you can run
dotnet formatfrom the command line when convenient (e.g. before requesting a PR review).
We provide a Docker Compose configuration, which is used during development to provide the required dependencies. This is split up into multiple service profiles to facilitate easily customization.
-
Some Docker settings are configured in the environment file,
dev/.env. Copy the example environment file:cd dev cp .env.example .env -
Open
.envwith your preferred editor. -
Set the
MSSQL_PASSWORDvariable. This will be the password for your MSSQL database server.:::caution
Your MSSQL password must comply with the following password complexity guidelines
- It must be at least eight characters long.
- It must contain characters from three of the following four categories:
- Latin uppercase letters (A through Z)
- Latin lowercase letters (a through z)
- Base 10 digits (0 through 9)
- Non-alphanumeric characters such as: exclamation point (!), dollar sign ($), number sign (#), or percent (%).
:::
-
You can change the other variables or use their default values. Save and quit this file.
-
Start the Docker containers.
Using PowerShell, navigate to the cloned server repo location, into the
devfolder and run the docker command below.docker compose --profile mssql --profile mail up -d
Which starts the MSSQL and local mail server containers, which should be suitable for most community contributions.
docker compose --profile cloud --profile mail up -d
Which starts MSSQL, mail, and Azurite container. The additional Azurite container is required to emulate Azure used by the Bitwarden cloud environment.
After you’ve run the docker compose command, you can use the
Docker Dashboard to manage your containers. You should
see your containers running under the bitwardenserver group.
:::caution
Changing MSSQL_PASSWORD variable after first running docker compose will require a re-creation of
the storage volume.
Warning: this will delete your development database.
To do this, run
docker compose --profile mssql down
docker volume rm bitwardenserver_edgesql_dev_dataAfter that, rerun the docker compose command from Step 5.
:::
In order to support ARM based development environments such as the M1 Macs, we use the Azure SQL Edge docker container instead of a normal Microsoft SQL Server container. It behaves mostly identical to a regular SQL Server instance and runs on port 1433.
You can connect to it using Azure Data Studio using the following credentials:
- Server: localhost
- Username: sa
- Password: (the password you set in
dev/.env)
The server uses emails for many user interactions. We provide a pre-configured instance of MailCatcher, which catches any outbound email and prevents it from being sent to real email addresses. You can open its web interface at http://localhost:1080.
:::note
This section applies to Bitwarden developers only.
:::
Azurite is an emulator for Azure Storage API and supports Blob, Queues and Table storage. We use it to minimize the online dependencies required for developing in a cloud environment.
To bootstrap the local Azurite instance, navigate to the dev directory in your server repo and run
the following commands:
-
Install the
Azmodule. This may take a few minutes to complete without providing any user feedback (it may appear frozen).pwsh -Command "Install-Module -Name Az -Scope CurrentUser -Repository PSGallery -Force" -
Run the setup script:
pwsh setup_azurite.ps1
You now have the MSSQL server running in Docker. The next step is to create the database that will be used by the Bitwarden server.
We provide a helper script which will create the development database vault_dev and also run all
migrations.
Navigate to the dev folder in your server repo and perform the following steps:
-
Create the database and run all migrations:
pwsh migrate.ps1
-
You should receive confirmation that each migration script has run successfully:
Performing /mnt/migrator/DbScripts/2017-08-19_00_InitialSetup.sql Performing /mnt/migrator/DbScripts/2017-08-22_00_LicenseCheckScripts.sql Performing /mnt/migrator/DbScripts/2017-08-30_00_CollectionWriteOnly.sql [...]
If migrations are being skipped even though this is a new database, see MSSQL Database Troubleshooting.
:::note
You’ll need to re-run the migration helper script regularly to keep your local development database up-to-date. See MSSQL Database for more information.
:::
The next step is to create two self-signed certificates for local development. We provide a helper script that will generate these certificates and add them to your system’s keychain or certificate store.
Navigate to the dev folder in your server repo and perform the following commands.
-
Generate the certificates and save them to your keychain:
sh create_certificates_mac.sh
-
You will be prompted to enter a password 3 times. Create a complex password and type it into the
Export Passwordfield on each prompt. You will not be able to copy/paste. -
You will receive output similar to the following. You will need to collect the generated certificate fingerprints for use in the Configure User Secrets section.
Certificate fingerprints: Identity Server Dev: 0BE8A0072214AB37C6928968752F698EEC3A68B5 Data Protection Dev: C3A6CECAD3DB580F91A52FC9C767FE780300D8AB -
Open Keychain Access and go to your login keychain.
-
Double-click the
Bitwarden Data Protection DevandBitwarden Identity Server Devcertificates. -
In each certificate, change the Trust settings to “Always Trust”.
-
Generate the certificates and save them to the Certificate Store:
.\create_certificates_windows.ps1 -
You will receive output similar to the following. You will need to collect the generated certificate fingerprints for use in the Configure User Secrets section.
PSParentPath: Microsoft.PowerShell.Security\Certificate::CurrentUser\My Thumbprint Subject ---------- ------- 0BE8A0072214AB37C6928968752F698EEC3A68B5 CN=Bitwarden Identity Server Dev C3A6CECAD3DB580F91A52FC9C767FE780300D8AB CN=Bitwarden Data Protection Dev
-
Generate the certificates and save them to your certificate store:
./create_certificates_linux.sh
-
You will receive output similar to the following. You will need to collect the generated certificate fingerprints for use in the Configure User Secrets section.
Certificate fingerprints: Identity Server Dev: 0BE8A0072214AB37C6928968752F698EEC3A68B5 Data Protection Dev: C3A6CECAD3DB580F91A52FC9C767FE780300D8AB
To run your local server environment as a licensed instance, you will need to download the
Licensing Certificate - Dev from the shared Engineering collection and install it. This can be
done by double-clicking on the downloaded certificate.
User secrets
are a method for managing application settings on a per-developer basis. They override the settings
in appSettings.json of each project. Your user secrets file should match the structure of the
appSettings.json file for the settings you intend to override.
We provide a helper script which simplifies setting user secrets for all projects in the server repository.
-
Get a template
secrets.json. We need to get an initial version ofsecrets.json, which you will modify for your own secrets values.Navigate to the
devfolder in your server repo and copy the examplesecrets.jsonfile.cp secrets.json.example secrets.json
- Copy the user secrets file from the shared Development collection into the
devfolder. - If you don't have access to the Development collection, contact our IT Manager to arrange access. Make sure you have first set up a Bitwarden account using your company email address.
- This
secrets.jsonis configured to use the dockerized Azurite and MailCatcher instances and is recommended for this guide.
- Copy the user secrets file from the shared Development collection into the
-
Update
secrets.jsonwith your own values:sqlServer>connectionString: insert your password where indicatedidentityServer>certificateThumbprint: insert your Identity certificate thumbprint from the previous stepdataProtection>certificateThumbprint: insert your Data Protection certificate thumbprint from the previous step
installation>idandkey: request a hosting installation Id and Key and insert them herelicenseDirectory: set this to an empty directory, this is where uploaded license files will be stored.
-
Once you have your
secrets.jsoncomplete, run this command to add the secrets to each Bitwarden server project:pwsh setup_secrets.ps1
The helper script also supports an optional flag which removes all existing settings before re-applying them:
pwsh setup_secrets.ps1 -clear:$TrueYou are now ready to build and run your development server.
-
Open a new terminal window in the root of the repository.
-
Restore the nuget packages required for the Identity service:
cd src/Identity dotnet restore -
Start the Identity service:
dotnet run
-
Test that the Identity service is alive by navigating to http://localhost:33656/.well-known/openid-configuration
-
In another terminal window, restore the nuget packages required for the Api service:
cd src/Api dotnet restore -
Start the Api Service:
dotnet run
-
Test that the Api service is alive by navigating to http://localhost:4000/alive
-
Connect a client to your local server by configuring the client’s Api and Identity endpoints. Refer to https://bitwarden.com/help/article/change-client-environment/ and the instructions for each client in the Contributing Documentation.
:::info
If you cannot connect to the Api or Identity projects, check the terminal output to confirm the ports they are running on.
:::
:::note
We recommend continuing with the Web Vault afterwards, since many administrative operations can only be performed in it.
:::
:::info
On macOS, you must run dotnet restore for each Project before it can be launched in the a
debugger.
:::
To debug:
- On Windows, right-click on each project > click Debug > click Start New Instance
- On MacOS, right-click each project > click Start Debugging Project
Launch the Api project and the Identity project by clicking the "Play" button for each project separately.
