+title: 'Nginx ansible role'
+description: 'The ansible role I use to manage my nginx web servers'
+date: '2024-10-28'
+tags:
+- ansible
+- nginx
+---
+
+## Introduction
+
+Before succumbing to nixos, I had been using an ansible role to manage my nginx web servers. Now that I am in need of it again I refined it a bit: here is the result.
+
+## The role
+
+### Vars
+
+The role has OS specific vars in files named after the operating system. For example in `vars/Debian.yaml` I have:
+
+``` yaml
+---
+nginx:
+ etc_dir: '/etc/nginx'
+ pid_file: '/run/nginx.pid'
+ www_user: 'www-data'
+```
+
+While in `vars/FreeBSD.yaml` I have:
+
+``` yaml
+---
+nginx:
+ etc_dir: '/usr/local/etc/nginx'
+ pid_file: '/var/run/nginx.pid'
+ www_user: 'www'
+```
+
+### Tasks
+
+The main tasks file setups nginx and the global configuration common to all virtual hosts:
+
+``` yaml
+---
+- include_vars: '{{ ansible_distribution }}.yaml'
+
+- name: 'Install nginx'
+ package:
+ name:
+ - 'nginx'
+
+- name: 'Make nginx vhost directory'
+ file:
+ path: '{{ nginx.etc_dir }}/vhost.d'
+ mode: '0755'
+ owner: 'root'
+ state: 'directory'
+
+- name: 'Deploy nginx configuration files'
+ copy:
+ src: '{{ item }}'
+ dest: '{{ nginx.etc_dir }}/{{ item }}'
+ notify: 'reload nginx'
+ loop:
+ - 'headers_base.conf'
+ - 'headers_secure.conf'
+ - 'headers_static.conf'
+ - 'headers_unsafe_inline_csp.conf'
+
+- name: 'Deploy nginx configuration template'
+ template:
+ src: 'nginx.conf'
+ dest: '{{ nginx.etc_dir }}/'
+ notify: 'reload nginx'
+
+- name: 'Deploy nginx certificates'
+ copy:
+ src: '{{ item }}'
+ dest: '{{ nginx.etc_dir }}/'
+ notify: 'reload nginx'
+ loop:
+ - 'adyxax.org.fullchain'
+ - 'adyxax.org.key'
+ - 'dh4096.pem'
+
+- name: 'Start nginx and activate it on boot'
+ service:
+ name: 'nginx'
+ enabled: true
+ state: 'started'
+```
+
+I have a `vhost.yaml` task file which currently simply deploys a file and reload nginx:
+
+``` yaml
+- name: 'Deploy {{ vhost.name }} vhost {{ vhost.path }}'
+ template:
+ src: '{{ vhost.path }}'
+ dest: '{{ nginx.etc_dir }}/vhost.d/{{ vhost.name }}.conf'
+ notify: 'reload nginx'
+```
+
+### Handlers
+
+There is a single `main.yaml` handler:
+
+``` yaml
+---
+- name: 'reload nginx'
+ service:
+ name: 'nginx'
+ state: 'reloaded'
+```
+
+### Files
+
+I deploy four configuration files in this role. These are all variants of the same theme and their purpose is just to prevent duplicating statements in the virtual hosts configuration files.
+
+`headers_base.conf`:
+
+``` nginx

+```
+
+### Templates
+

+
+ include vhost.d/*.conf;
+}
+```
+
+## Usage example
+
+I do not call the role from a playbook, I prefer running the setup from an application's role that relies on nginx using a `meta/main.yaml` containing something like:
+
+``` yaml
+---
+dependencies:
+ - role: 'borg'
+ - role: 'nginx'
+ - role: 'postgresql'
+```
+
+Then from a tasks file:
+
+``` yaml
+- include_role:
+ name: 'nginx'
+ tasks_from: 'vhost'
+ vars:
+ vhost:
+ name: 'www'
+ path: 'roles/www.adyxax.org/files/nginx-vhost.conf'
+```
+
+I did not find an elegant way to pass a file path local to one role to another. Because of that, here I just specify the full vhost file path complete with the `roles/` prefix.
+
+### Conclusion
+
+I you have an elegant idea for passing the local file path from one role to another do not hesitate to ping me!

+tags:
+- ansible
+- podman
+---
+
+## Introduction
+
+Before succumbing to nixos, I had was running all my containers on k3s. This time I am migrating things to podman and trying to achieve a lighter setup. This article presents the ansible role I wrote to manage podman containers.
+
+## The role
+
+### Tasks
+
+The main tasks file setups podman and the required network configurations with:
+
+``` yaml
+---
+- name: 'Run OS specific tasks for the podman role'
+ include_tasks: '{{ ansible_distribution }}.yaml'
+
+- name: 'Make podman scripts directory'
+ file:
+ path: '/etc/podman'
+ mode: '0700'
+ owner: 'root'
+ state: 'directory'
+
+- name: 'Deploy podman configuration files'
+ copy:
+ src: 'cni-podman0'
+ dest: '/etc/network/interfaces.d/'
+ owner: 'root'
+ mode: '444'
+```
+
+My OS specific task file `Debian.yaml` looks like this:
+
+``` yaml
+---
+- name: 'Install podman dependencies'
+ ansible.builtin.apt:
+ name:
+ - 'buildah'
+ - 'podman'
+ - 'rootlesskit'
+ - 'slirp4netns'
+
+- name: 'Deploy podman configuration files'
+ copy:
+ src: 'podman-bridge.json'
+ dest: '/etc/cni/net.d/87-podman-bridge.conflist'
+ owner: 'root'
+ mode: '444'
+```
+
+The entrypoint tasks for this role is the `container.yaml` task file:
+
+``` yaml
+---
+# Inputs:
+# container:
+# cmd: optional(list(string))
+# env_vars: list(env_var)
+# image: string
+# name: string
+# publishs: list(publish)
+# volumes: list(volume)
+# With:
+# env_var:
+# name: string
+# value: string
+# publish:
+# container_port: string
+# host_port: string
+# ip: string
+# volume:
+# dest: string
+# src: string
+
+- name: 'Deploy podman systemd service for {{ container.name }}'
+ template:
+ src: 'container.service'
+ dest: '/etc/systemd/system/podman-{{ container.name }}.service'
+ owner: 'root'
+ mode: '0444'
+ notify: 'systemctl daemon-reload'
+
+- name: 'Deploy podman scripts for {{ container.name }}'
+ template:
+ src: 'container-{{ item }}.sh'
+ dest: '/etc/podman/{{ container.name }}-{{ item }}.sh'
+ owner: 'root'
+ mode: '0500'
+ register: 'deploy_podman_scripts'
+ loop:
+ - 'start'
+ - 'stop'
+
+- name: 'Restart podman container {{ container.name }}'
+ shell:
+ cmd: "systemctl restart podman-{{ container.name }}"
+ when: 'deploy_podman_scripts.changed'
+
+- name: 'Start podman container {{ container.name }} and activate it on boot'
+ service:
+ name: 'podman-{{ container.name }}'
+ enabled: true
+ state: 'started'
+```
+
+### Handlers
+
+There is a single `main.yaml` handler:
+
+``` yaml
+---
+- name: 'systemctl daemon-reload'
+ shell:
+ cmd: 'systemctl daemon-reload'
+```
+
+### Files
+
+Here is the `cni-podman0` I deploy on Debian hosts. It is required for the bridge to be up on boot so that other services can bind ports on it. Without this, the bridge would only come up when the first container starts which is too late in the boot process.

+
+## Conclusion
+
+I enjoy this design, it works really well. I am missing a task for deprovisioning a container but I have not needed it yet.

+description: 'How I deploy privatebin with ansible'
+date: '2024-11-17'
+tags:
+- ansible
+- privatebin
+---
+
+## Introduction
+
+I am migrating several services from a NixOS server (myth.adyxax.org) to a Debian server (lore.adyxax.org). Here is how I performed the operation for my self hosted [privatebin](https://privatebin.info/) served from paste.adyxax.org.
+
+## Ansible role
+
+### Meta
+
+The `meta/main.yaml` contains the role dependencies:
+
+``` yaml
+---
+dependencies:
+ - role: 'borg'
+ - role: 'nginx'
+ - role: 'podman'
+```
+
+### Tasks
+
+The `tasks/main.yaml` file only creates a data directory and drops a configuration file. All the heavy lifting is then done by calling other roles:
+
+``` yaml
+---
+- name: 'Make privatebin data directory'
+ file:
+ path: '/srv/privatebin'
+ owner: '65534'
+ group: '65534'
+ mode: '0750'
+ state: 'directory'
+
+- name: 'Deploy privatebin configuration file'
+ copy:
+ src: 'privatebin.conf.php'
+ dest: '/etc/'
+ owner: 'root'
+ mode: '0444'
+ notify: 'restart privatebin'
+
+- include_role:
+ name: 'podman'
+ tasks_from: 'container'
+ vars:
+ container:
+ cmd: ['--config-path', '/srv/cfg/conf.php']
+ name: 'privatebin'
+ env_vars:
+ - name: 'PHP_TZ'
+ value: 'Europe/Paris'
+ - name: 'TZ'
+ value: 'Europe/Paris'
+ image: '{{ versions.privatebin.image }}:{{ versions.privatebin.tag }}'
+ publishs:
+ - container_port: '8080'
+ host_port: '8082'
+ ip: '127.0.0.1'
+ volumes:
+ - dest: '/srv/cfg/conf.php:ro'
+ src: '/etc/privatebin.conf.php'
+ - dest: '/srv/data'
+ src: '/srv/privatebin'
+
+- include_role:
+ name: 'nginx'
+ tasks_from: 'vhost'
+ vars:
+ vhost:
+ name: 'privatebin'
+ path: 'roles/paste.adyxax.org/files/nginx-vhost.conf'
+
+- include_role:
+ name: 'borg'
+ tasks_from: 'client'
+ vars:
+ client:
+ jobs:
+ - name: 'data'
+ paths:
+ - '/srv/privatebin'
+ name: 'privatebin'
+ server: '{{ paste_adyxax_org.borg }}'
+```
+
+### Handlers
+
+There is a single handler:
+
+``` yaml
+---
+- name: 'restart privatebin'
+ service:
+ name: 'podman-privatebin'
+ state: 'restarted'
+```
+
+### Files
+
+First there is my privatebin configuration, fairly simple:

+ }
+ ssl_certificate adyxax.org.fullchain;
+ ssl_certificate_key adyxax.org.key;
+}
+```
+
+## Migration process
+
+The first step is to deploy this new configuration to the server:
+
+``` shell
+make run limit=lore.adyxax.org tags=paste.adyxax.org
+```
+
+After that I log in and manually migrate the privatebin data folder. On the old server I make a backup with:
+
+``` shell
+systemctl stop podman-privatebin
+tar czf /tmp/privatebin.tar.gz /srv/privatebin/
+```
+
+I retrieve this backup on my laptop and send it to the new server with:
+
+``` shell
+scp root@myth.adyxax.org:/tmp/privatebin.tar.gz .
+scp privatebin.tar.gz root@lore.adyxax.org:
+```
+
+On the new server, I restore the backup with:
+
+``` shell
+systemctl stop podman-privatebin
+tar -xzf privatebin.tar.gz -C /srv/privatebin/
+chown -R 65534:65534 /srv/privatebin
+chmod -R u=rwX /srv/privatebin
+systemctl start podman-privatebin
+```
+
+I then test the new server by setting the record in my `/etc/hosts` file. Since all works well, I rollback my change to `/etc/hosts` and update the DNS record using OpenTofu. I then clean up by running this on my laptop:
+
+``` shell
+rm privatebin.tar.gz
+ssh root@myth.adyxax.org 'rm /tmp/privatebin.tar.gz'
+ssh root@lore.adyxax.org 'rm privatebin.tar.gz'
+```
