message-writer

Create json file to be used by the WMS server.

1. Clone the repository

git clone https://github.com/nordsat/message_writer.git

2. Move to the repository and build the container

cd message_writer && podman build -t message-worker .

3. Download the area file from https://github.com/pytroll/satpy/blob/main/satpy/etc/areas.yaml

4. Create the configuration file Configuration file for the script has the following information:

• output file name path, for example /tmp/list-of-files.json
• area file path (taken from https://github.com/pytroll/satpy/blob/main/satpy/etc/areas.yaml)
• filepattern, for example /eodata/fci-out/{start_time:%Y%m%d_%H%M}_{platform_name}_{area}_{product}.tif

Example file called config_fci.yaml:

filename: /tmp/list-of-files.json
area_file:  /usr/local/bin/message-writer/areas.yaml
filepattern: /eodata/fci-out/{start_time:%Y%m%d_%H%M}_{platform_name}_{area}_{product}.tif

5. Run the container mounting the area file, the configuration file (from point 2) and the folder with the actual products created with satpy

podman run -it -v ./areas.yaml:/usr/local/bin/message-writer/areas.yaml -v ./config_fci.yaml:/usr/local/bin/message-writer/config_fci.yaml -v /tmp/:/tmp/ -v /home/murdaca/fci-data/:/eodata/fci-out  message-worker python3 create_file.py config_fci.yaml /eodata/fci-out/

Example output of the json (formatted) from /tmp/list-of-files.json:
