+# Deployment with Ansible
+
+## Getting started
+
+### Installation
+
+```bash
+python3 -m pip install ansible
+```
+
+### Inventory
+
+Update the [inventories/](inventories/) folder with your SSH information.
+
+Configuration your ssh client configuration at `~/.ssh/config`.
+
+```bash
+Host heroctf-ctfd
+    User root
+    Hostname XXX
+    Port 22
+    IdentityFile /home/xanhacks/.ssh/heroctf/linode
+
+Host heroctf-challenge-1
+    User root
+    Hostname XXX
+    Port 22
+    IdentityFile /home/xanhacks/.ssh/heroctf/linode
+
+Host heroctf-challenge-2
+    User root
+    Hostname XXX
+    Port 22
+    IdentityFile /home/xanhacks/.ssh/heroctf/linode
+
+# [...]
+```
+
+Check the SSH connection is working and accept all SSH fingerprints.
+
+```bash
+ansible -i inventories/dev -m ping all -v
+ansible -i inventories/prod -m ping all -v
+```
+
+## Roles
+
+### Prerequisites
+
+#### Features
+
+1. Update APT cache & install usefull packages (`git`, `curl`, `vim`...).
+2. Configure the VM timezone, hostname and create a low privileged account.
+3. Install and start `docker` & `docker-compose`.
+
+### CTFd
+
+#### Features
+
+1. Clone CTFd at a specific version.
+2. Overwrite the default `docker-compose.yml` and `http.conf` with enhanced configuration (HTTPs and better performance).
+3. Upload HTTPs certificates.
+4. (optional) Extract custom CTFd theme.
+5. (optional) Enable first blood Discord webhook.
+
+> Generate your HTTPs certificates using certbot: `certbot certonly --manual --preferred-challenges dns -d 'ctf.heroctf.fr' --work-dir $(pwd) --logs-dir $(pwd) --config-dir $(pwd)`
+
+#### Setup & Run
+
+1. Configure the `ctfd` role at [./group_vars/ctfd.yml](./group_vars/ctfd.yml).
+2. Add `fullchain.pem` and `privkey.pem` to [./roles/ctfd/files/certs](./roles/ctfd/files/certs).
+3. Configure the [./roles/ctfd/files/.env.sample](./roles/ctfd/files/.env.sample) file to `.env`.
+4. (optional) Add CTFd Theme `hacker_theme.zip` at [./roles/ctfd/files/](./roles/ctfd/files/).
+
+```bash
+ansible-playbook ctfd.yml -i inventories/dev
+ansible-playbook ctfd.yml -i inventories/prod
+```
+
+### Challenges
+
+#### Features
+
+1. Upload and configure the Github SSH private key to see private repositories.
+2. Clone the challenge repository.
+
+> You can create a Github SSH key for a repository under the `Settings > Deploy keys` tab, then click on `Add deploy key`.
+
+#### Setup & Run
+
+1. Configure `challenges` role at [./group_vars/challenges.yml](./group_vars/challenges.yml).
+2. Add your Github private SSH key to [./roles/challenges/files/](./roles/challenges/files/) under the name `github.key`.
+
+```bash
+ansible-playbook challenges.yml -i inventories/dev
+ansible-playbook challenges.yml -i inventories/prod
+```
+
+## Linter
+
+Use [ansible-lint](https://github.com/ansible/ansible-lint) to checks playbooks for practices and behavior that could potentially be improved.
+
+```bash
+python3 -m pip install ansible-lint
+ansible-lint
+```
+
+## About
+
+Tested on debian 12.
