Instalación de Grafana, Prometheus y Pi-hole con Ansible

 

Instalación de Grafana, Prometheus y Pi-hole con Ansible en Raspberry Pi

Se describe el proceso para instalar estas aplicaciones en Raspberry Pi:

  uname -r

Devuelve el siguiente resultado sobre la version del SO:

  6.1.0-rpi6-rpi-v8

Para configurar tu red y monitorearla con Grafana, Prometheus y Pi-hole usando Ansible, sigue estos pasos:

1. Instala ansible:

  pipx install --include-deps ansible
  pipx upgrade --include-injected ansible

2. Clona el repositorio:

  git clone https://github.com/geerlingguy/internet-pi.git
  cd internet-pi/
  cp example.inventory.ini inventory.ini
  cp example.config.yml config.yml
  nano inventory.ini 
  nano config.yml 
  sudo ansible-playbook main.yml

Yo he tenido problemas al ejecutar el playbook porque daba el siguiente error al instalar docker-compose:

TASK [Install Docker Compose using Pip.] *************************************************************************

Para solucionarlo he intentado instalar docker-compose manualmente, pero tambien da el siguiente error:

 pip install docker-compose

error: externally-managed-environment

× This environment is externally managed
╰─> To install Python packages system-wide, try apt install
    python3-xyz, where xyz is the package you are trying to
    install.
    
    If you wish to install a non-Debian-packaged Python package,
    create a virtual environment using python3 -m venv path/to/venv.
    Then use path/to/venv/bin/python and path/to/venv/bin/pip. Make
    sure you have python3-full installed.

note: If you believe this is a mistake, please contact your Python installation or OS distribution provider. You can override this, at the risk of breaking your Python installation or OS, by passing --break-system-packages.

Tambien lo intento instalar con:

 pipx install docker-compose

pero tambien da error:

Fatal error from pip prevented installation. Full pip output in file:
    /.local/pipx/logs/cmd_2023-11-14_22.35.44_pip_errors.log

pip seemed to fail to build package:
    PyYAML6,>=3.10

Some possibly relevant errors from pip install:
    error: subprocess-exited-with-error
    AttributeError: cython_sources

Error installing docker-compose.

Entonces sigo las instrucciones descritas en este enlace para instalar docker-compose en un entorno virtual

3. Para instalar Docker Compose manualmente:

 python3 -m venv /ruta/a/tu/entorno_virtual
 source /ruta/a/tu/entorno_virtual/bin/activate
 pip install PyYAML==5.4.1
 pipx install docker-compose

Después de seguir estos pasos, deberías tener instalados Grafana, Prometheus, Pi-hole y Docker Compose para monitorear tu red.

Recuerda ajustar los comandos según tu entorno y las necesidades específicas de tu configuración.

Despues modifica el archivo docker.yml para actualizar el path al comando de instalacion a la nueva ubicacion en el entorno virtual

  nano tasks/docker.yml

El archivo docker.yml contiene pip3 como ejecutable, para que se ejecute pip3 en el entorno virtual, modifica el path del executable:

  - name: Install Docker Compose using Pip.
    ansible.builtin.pip:
    name: docker-compose
    state: present
    executable: /ruta/a/tu/entorno_virtual/bin/pip3

Ahora activamos el entorno virtual y ejecutamos el playbook:

  source ~/python-venv/bin/activate
  ansible-playbook ~/internet-pi/main.yml
