Containerized Treebird FE Build

This git repo contains files needed to build a docker container for Nekobit's Treebird C-FCGI based front end for Pleroma.

Requirements - Build

• docker (or docker.io on older distros)
• bash
• git

Requirements - Run

• docker (or docker.io on older distros)
• nginx (or another FCGI capable web server)
• bash (only for commands in the instructions. If you mentally translate you dont need it)

Installing

To install you can either build the container yourself or grab the latest from the Gitea release tab. Here I'm going to assume the latter.

1. On your server download the treebird-latest and treebird-latest-static-files tars

2. If you don't have it already, install docker (apt install docker or docker.io for old debian) NOTE: for other distros obviously this will differ so find it in your package manager

3. Load the image

	sudo docker load -i treebird-latest.tar.gz

4. Add an unprivileged treebrid user and group to the host (this is needed to avoid uid/gid conflicts)

	sudo useradd -r -s /bin/false -c 'Treebird FE user' -U treebird

5. Run the container as below to start in daemon mode (-d) on port 4008 as user:group treebird:treebird

	docker run \
	    --rm \
	    --name treebird \
	    -p 127.0.0.1:4008:4008 \
		-u "`id -u treebird`:`id -g treebird`" \
	    -e TREEBIRD_CFG_INSTANCE_URL="https://my.instance.domain/" \
	    -d "treebird:latest"

	# You can verify this started by checking `docker ps`
	# This should remain up until either the system is rebooted or the docker
	# daemon is restarted (or you can manually stop with the docker stop command).

	# To have it auto start on reboot you need to either add to your init system
	# or manage with a docker wrapper like docker-compose or etc.
	# TODO: instructions

6. Add a web folder for the static files

	sudo mkdir -p /var/www/treebird
	sudo chmod a+r /var/www/treebird

7. Extract static files to web folder

	tar -xzf treebird-static-latest.tar.gz
	sudo cp -r treebird-latest/* /var/www/treebird

8. Setup your Nginx Configuration (other servers idk for now)

	# In case the folders do not exist yet, do the following
	sudo mkdir -p /etc/nginx/sites-{available,enabled}

	# If you needed the above, ensure you also you have `include sites-enabled/*;`
	# in the http section of `/etc/nginx/nginx.conf`

	# First edit treebird.nginx to replace treebird.example.com with your treebird hostname
	sudo cp treebird.nginx /etc/nginx/sites-available/treebird.nginx
	sudo ln -s /etc/nginx/{sites-available,sites-enabled}/treebird.nginx

	# Activate SSL for domain (the usual... select domain and etc.)
	sudo certbot --nginx

	# Start nginx
	sudo systemctl start nginx

It should now be running on the domain you configured.

Updating

This is process is similar to the install, but without the need for config changes.

1. Download the latest tarballs from the release tab again.

2. Stop the running container and remove the old image

	docker stop treebird
	docker rmi treebird:latest

3. Load the new one

	docker load -i treebird-latest-HASH.tar.gz

4. Start the container again

	docker run \
	    --rm \
	    --name treebird \
	    -p 127.0.0.1:4008:4008 \
		-u "`id -u treebird`:`id -g treebird`" \
	    -e TREEBIRD_CFG_INSTANCE_URL="https://my.instance.domain/" \
	    -d "treebird:latest"

5. Extract and update static files

	tar -xzf treebird-static-files-HASH.tar.gz
	sudo cp -rf treebird-latest/* /var/www/treebird

Your install should now be running and up to date

Building

Building the container should be as simple as running build_container.sh and waiting for the build to complete.

./build_container.sh [tag (optional, defaults to latest)]

Running

The run_container.sh script will start the Treebird FCGI container on port 4008 ready to receive requests from nginx or whatever FCGI capable http server you have.

# NOTE: The instance url MUST contain the trailing /
./run_container.sh [instance, e.g. "https://sleepy.cafe/"] [tag (optional, latest)]

Running - Local Nginx

For local use and testing an nginx Dockerfile is provided in the nginx-test folder. To use it, after building the Treebird container, do the following.

cd nginx-test
./build_container.sh [tag (optional, defaults to latest)]

Then to run it just run run_container.sh. This will not launch with the -d option so it will close when you close the terminal (since this is only for testing).

./run_container.sh [tag (optional, defaults to latest)]

From here, you can open your preferred web browser to http://localhost/ and Treebird should appear.
