bitwarden-directory-connector-containers

This project is designed to simplify automation for bwdc when the user has more than one sync profile. It utilizes containers, condensed key=value configuration files (in lieu of data.json files, however those are also unintentionally supported) and a separate secrets manager (podman, or anything that can inject them as environment vars) so that no secrets are on disk or stored within the generated images. Users can execute a single script once, and it will build an image per sync configuration file, then run bwdc test and/or bwdc sync on all of them.

This project has two sets of container images:

• The bwdc-base image (also referred to as the "base image"), which basically just has bwdc installed and a helper script. This is published to ghcr.io via the Github packages for this project (See base-image.md for details).
• The "typed images", which are built off of bwdc-base and is specific to a Directory Connector type, often abbreviated here as $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE (See typed-images.md for details).

Note

Project currently only supports the Gsuite directory connector type for the simplified config file method (See directory-connector issues), but it supports data.json files of all directory connector types (admittedly awkwardly, as it was not the project's purpose. See BYO data.json method).

Background

I personally did not like dealing with a bunch of data.json files or having secrets stored in them. So I came up with a way to use simple key=value configuration files (which mimic the Bitwarden Directory Connector app screens), and generate individual container images containing helper scripts to manage login/logout/test/sync.

Scripts

Below is a summary of the main scripts in this project, the tasks they are related to, files they depend on and links to documentation that explain them.

Task	Script	Dependencies	Documentation
Build the bwdc-base image, which is the root of the rest of the containers. Published by @hdub-tech to GitHub packages for this project.	build-base-image.sh	- Containerfile - defaults.conf / custom.conf - build-push-base.yml	base-image.md
The ENTRYPOINT of the bwdc-base image, and therefore all typed images built off of it.	entrypoint.sh	N/A	base-image.md
Build per-configuration file images, one type per run, optionally without using the podman cache and optionally testing login even if the image was already built.	build-typed-images.sh	- defaults.conf / custom.conf - $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE/Containerfile (gsuite Containerfile, as an example) - $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE/$CONFNAME.conf (gsuite argfile template, as an example)	- config-files.md - managing-secrets.md - typed-images.md
Install/verify dependencies (optional), build all images of all types (EXCEPT the bwdc-base) and/or push and/or run all the images.	ci.sh	- defaults.conf / custom.conf - */Containerfile (gsuite Containerfile, as an example) - */$CONFNAME.conf (gsuite argfile template, as an example)	- config-files.md - typed-images.md
Utility functions used by other scripts	functions.sh	N/A	N/A

Requirements

• Podman>=4.5.0 (--build-arg-file option) (Issue #5 - add Docker support)
• bash
• apt (ONLY if using ci.sh WITHOUT -s option)
• jq (ONLY if using podman secrets, which is not recommended with this project at this time: Issue #16)

Getting Started

Tip

Read through these steps once before checking out the detailed documentation links!

It is recommended (but not required) that you use this repository as a submodule within your own repository "in production" (particularly if you are using ci.sh), where your repository contains your custom.conf and type-specific configuration files (See config-files.md for details). If you are just playing around and trying this out though, use the "no submodule" version of the steps below.

1. OPTIONAL: Copy the defaults.conf file to custom.conf file, and update BWDC_VERSION, SECRETS_MANAGER and IMAGE_NAMESPACE as needed (Detailed comments in file; detailed documentation: config-files.md). Skip this step if the defaults are acceptable.

   # EXAMPLE WHEN USED AS SUBMODULE
   cp ./bitwarden-directory-connector-containers/defaults.conf ./custom.conf

   # EXAMPLE FROM THIS PROJECT'S DIRECTORY (no submodule)
   cp defaults.conf custom.conf

2. Copy the $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE/argfile.conf.template to $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE/$DESCRIPTIVE_NAME.conf and update the conf file for your sync needs. This template contains detailed comments on what and how to update. (Detailed documentation at config-files.md). Do this once per sync profile / data.json file.

   # GSUITE EXAMPLE WHEN USED AS SUBMODULE
   mkdir gsuite
   cp bitwarden-directory-connector-containers/gsuite/argfile.conf.template gsuite/admins.conf
   vi gsuite/admins.conf

   # GSUITE EXAMPLE FROM THIS PROJECT'S DIRECTORY (no submodule)
   cp gsuite/argfile.conf.template gsuite/admins.conf
   vi gsuite/admins.conf

3. Export your BW_CLIENTID and BW_CLIENTSECRET, as well as any type specific secrets specified in $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE/env.vars (gsuite env sample) (Detailed documentation: managing-secrets.md).

   # EXAMPLE (disabling history for commands with leading spaces, then issue exports with a leading space)
   # Common / needed for all Types
   export HISTCONTROL="ignorespace"  # or ignoreboth, if you do not want dupes in history either
    export BW_CLIENTID="organization.123456"
    export BW_CLIENTSECRET="keepbitwardensecretsecret"

   # GSUITE EXAMPLE
    export BW_GSUITEKEY="keepgsuitekeysecret

4. Run the desired scripts for building and running the images:

   a. IF YOU WANT TO INSTALL DEPENDENCIES, BUILD ALL IMAGES OF ALL TYPES (not bwdc-base), AND RUN ALL THE IMAGES IN CONFIG, SYNC or TEST MODE (One script to rule them all): Run the ci.sh script (Detailed documentation: typed-images.md).

   # EXAMPLE WHEN USED AS SUBMODULE
   # Use -h for all options with full descriptions
   # USAGE: ci.sh [-b] [-p] [-r config|test|sync] [-d CONFS_DIR] [-s]
   ./bitwarden-directory-connector-containers/ci.sh -b -r test

   # EXAMPLE FROM THIS PROJECT'S DIRECTORY (no submodule):
   # Use -h for all options with full descriptions
   # USAGE: ci.sh [-b] [-p] [-r config|test|sync] [-d CONFS_DIR] [-s]
   ./ci.sh -d $PWD -b -r test

   b. IF YOU ONLY WANT TO BUILD THE IMAGES OF ONE TYPE AND TEST BWDC LOGIN/LOGOUT: Run the build-typed-images.sh script once per $BITWARDENCLI_CONNECTOR_DIRECTORY_TYPE, to build one image per config file and run bwdc login and bwdc logout, which is necesary for the build image process. No secrets will be stored to disk or in the environment of the produced image (Detailed documentation: typed-images.md. NOTE: currently does not support submodule method, Issue #14).

   # GSUITE EXAMPLE: Use -h for all options
   ./build-typed-images.sh -t gsuite

5. Copy the desired workflows to use in your superproject (Detailed sample workflows documentation):

   # From $YOUR_PROJECT_REPO, where bitwarden-directory-connector-containers is a submodule
   mkdir --parents .github/workflows
   cp ./bitwarden-directory-connector-containers/.github/workflows/samples/*.yml ./.github/workflows/

Thank You

• Thank you to the folks at @bitwarden for creating the open source Directory Connector.
• Thank you to the folks at @auth0 for sharing an excellent README-sample.md, which helped me craft this one.
• And a super extra thank you to my boss (Nick Popovich @ Rotas Security), who let me take extra time on completing my assignment to design this project generically and share it with the world (and my future self, who will completely forget all of this as soon as I roll onto the next project).
