Playbooks to install and configure Pytroll-based satellite data processing pipelines and optionally a WMS server. These playbooks are used in the European Weather Cloud (EWC) environment.

Overview

ewc-playbooks provides Ansible playbooks to set up a robust, containerized environment for processing satellite data using the Pytroll ecosystem. Supported datasets include:

• FCI – Flexible Combined Imager (MTG-I)
• SEVIRI – Spinning Enhanced Visible and Infrared Imager (MSG)
• VIIRS – Visible Infrared Imaging Radiometer Suite (NOAA/NASA)

Optionally, a WMS server can be deployed to serve processed imagery for visualization in GIS clients.

Key features:

• Automated provisioning of multiple containers.
• Scalable and isolated pipelines for each satellite sensor.
• Integration with Pytroll tools for reading, processing, and resampling satellite data.
• Optional WMS server for serving processed data.

Tested Platforms

This playbook and container setup have been tested on the following platforms:

Note: Other Linux distributions may work but have not been officially tested.

Run the Playbook

1. Install Ansible

You can install Ansible and other Python dependencies in a virtual environment:

python3 -m venv venv
source venv/bin/activate
pip install ansible

For more details, see the Ansible installation guide: https://docs.ansible.com/ansible/latest/installation_guide/intro_installation.html

2. Define Your Inventory

Create the inventory file to list your hosts and groups. Example:

[satellite_hosts]
localhost ansible_connection=local

3. Run the main playbook (or any specific playbook) using:

ansible-playbook -i inventory satellite-data-processing-main.yaml

This will:

• Build and launch containers for processing FCI, SEVIRI, and VIIRS data.
• Optionally deploy WMS containers to serve processed outputs.

Optional Variables

You can customize the playbook behavior using the following variables:

Passing Variables to Ansible

You can override these defaults when running the playbook by using the --extra-vars (-e) flag:

ansible-playbook -i inventory path/to/playbook/filename.yaml -e "satellite_data_type=seviri"
