This is a Drone configuration to build Docker image containing both Bitwarden Web interface and Bitwarden-compatible API implementation in ruby.
The build is using upstream code for the Vault (web interface) and universal's fork of bitwarden-ruby.
You can run your own instance by running:
docker run -d -v /bitwarden_data/:/bitwarden/api/db/ -p 8080:8080 mprasil/bitwarden-ruby
The important part is the volume mapping. The above example will preserve your passwords DB in /bitwarden_data directory on the host machine - adapt this path to your preference.
After you run above command, bitwarden will be available on port 8080. Note that the service is exposed over http, which might be fine to use over local network if you can trust it, but if you want to expose and use the service over the internet using https is strongly encouraged. You can use Caddy or other https capable proxy server for that purpose.
You don't have to build your own image to use Bitwarden, you can just use mprasil/bitwarden-ruby for that, however if you need some extra modifications, the process is fairly simple.
This configuration is written for Drone, however it shouldn't be har to write similar configuration for CI tool of your choice. Essentially Drone will run two build scripts in dedicated node/ruby docker images and will then compile the output of these into final image. The .drone.yml file is pretty self-explanatory. Building by hand:
Build web vault:
docker run -it --rm --name bitwarden-vault-build -v "$PWD":/usr/src/app -w /usr/src/app node:8-alpine sh /usr/src/app/build-web.sh
build ruby app:
docker run -it --rm --name bitwarden-api-build -v "$PWD":/usr/src/app -w /usr/src/app ruby:2.4-alpine3.7 sh build-api.sh
build image:
docker build -t bitwarden-ruby .
