2FAuth/docker

Docker

You can run 2fauth in a single Docker container.

Features

• Runs without root as user www-data
• 
• Compatible with amd64 only for now
• Stores data in a Sqlite database file

Setup

1. Create a directory on your host 2fauth:

   mkdir 2fauth
   

2. If your host is not Windows: since the container runs without root as user www-data (uid=33(www-data) gid=33(www-data) groups=33(www-data)), you need to fix the ownership and permissions of that directory:

   chown 33:33 2fauth
   chmod 700 2fauth
   

3. Run the container interactively:

   docker run -it --rm -p 8000:8000/tcp \
   -v /yourpath/2fauth:/2fauth 2fauth/2fauth
   

4. Access it at http://localhost:8000

You can stop it with CTRL+C.

• You can also run it in the background by replacing -it --rm with -d.
• You can set environment variables available (see the .env.example) with -e, for example -e APP_NAME=2FAuth.
• You can also use the docker-compose.yml with docker-compose and modify it as you wish.

Use an existing SQLite file

If you already have an SQLite file, move it to /yourpath/2fauth/database.sqlite on your host before starting the container. Don't forget to fix its ownership and permissions if you run on *nix:

chown 33:33 /yourpath/2fauth/database.sqlite
chmod 700 /yourpath/2fauth/database.sqlite

The container will automagically pick it up.

Update

The Docker image 2fauth/2fauth is built on every commit pushed to the master branch.

You can therefore pull the image with docker pull 2fauth/2fauth and restart the container to update it.

Build the image

You can build the image from the master branch with docker and git using:

docker build -t 2fauth/2fauth https://github.com/Bubka/2FAuth.git

You can also build a specific commit (see master's commits) by appending the commit hash with #<commit-hash> to the command. For example:

docker build -t 2fauth/2fauth https://github.com/Bubka/2FAuth.git#fba9e29bd4e3bb697296bb0bde60ae869537528b

Implementation details

• The container is based on debian:buster-slim
• The container runs an Nginx server together with PHP-FPM as a system service.
• The /srv directory holds the repository data and PHP code.
• The /2fauth directory is targeted for the container end users.
• By default the container logs the Nginx logs and the PHP-FPM logs. The application logs can be found in /2fauth/storage/logs.

TODOs

• Base image (or other image) on Alpine (for a possibly smaller image)
