Adhokku Save Abandoned

A toy FreeBSD PaaS

Project README


A toy single-host PaaS powered by FreeBSD jails and managed with Ansible.

How it works

When you deploy an application using Adhokku, Adhokku creates a new jail on the remote host and provisions it from a fixed clean state using the instructions in the Jailfile in your Git repository. (A Jailfile is a simple POSIX shell script; here is one.) All jails sit behind a reverse proxy that directs traffic to one of them based on the host's domain name or IP address in the HTTP request. When a new jail has been provisioned for an application, Adhokku seemlessly reconfigures the reverse proxy to send traffic to it instead of the one currently active for that application.

Adhokku is built as an Ansible role, so it operates over SSH and requires no specialized daemons running on the remote host for setup or deployment.


Ansible 2.0 or later and Git installed on the developer machine. FreeBSD 10.4 or 11.1, -RELEASE or -STABLE, on the server (other versions may work but haven't been tested). An SSH key pair.


The following instructions show how to get Adhokku and an example application running in a VM on your development machine using Vagrant. This process should require no FreeBSD-specific knowledge, though modifying the Jailfile to customize the application may.

If you are familiar with FreeBSD you can install Adhokku on a host of your choice. To do this, get the host to a point where it accepts SSH connections with your SSH key and lets you run commands as root via sudo. Then, follow the instructions with the appropriate modifications like skipping step 5.

Note that Adhokku expects a clean FreeBSD installation that isn't used for anything else and does not account for possible conflicts with other software.

1. Install Adhokku using Ansible Galaxy and set the environment variable ADHOKKU_PATH.

export ANSIBLE_ROLES_PATH="$HOME/.ansible/roles"
ansible-galaxy install adhokku.adhokku
export ADHOKKU_PATH="$ANSIBLE_ROLES_PATH/adhokku.adhokku"

2. Create a new project, e.g., in ~/projects/adhokku-hello/.

cd ~/projects/
mkdir adhokku-hello
cd adhokku-hello
git init

3. Create the Ansible files needed to run Adhokku commands with adhokku-tool.

sh "$ADHOKKU_PATH/adhokku-tool" init

4. Add a submodule for a Jailfile. Your project's Jailfile will import it.

git submodule add
echo '/.vagrant' > .gitignore
echo '. /app/adhokku-caddy/Jailfile' > Jailfile
mkdir static
echo '<h1>Hello, world!</h1>' > static/index.html
git add .
git commit -m 'Initial commit'

5. If you do not have a FreeBSD VM running Adhokku yet, create a new one with Vagrant.

cp "$ADHOKKU_PATH/Vagrantfile" .
vagrant up || vagrant up

6. Set up Adhokku on the VM with Ansible.

ansible-playbook -i inventory playbooks/setup.yml

If you get an SSH error like "Failed to connect to the host via ssh." at this point, remove the key for other Vagrant VMs from your ~/.ssh/known_hosts file with the commands

ssh-keygen -R '[]:2222' -f ~/.ssh/known_hosts
ssh-keygen -R '[localhost]:2222' -f ~/.ssh/known_hosts

6. Deploy the application.

ansible-playbook -i inventory playbooks/deploy.yml
