Docker image to generate dmrpp files from netCDF and HDF files

Supported get_dmrpp configuration

Via Cumulus Collection configuration

{
  "config": {
    "meta": {
      "dmrpp": {
        "dmrpp_regex" : "^.*.H6",
        "options": [
          {
            "flag": "-M"
          },
          {
            "flag": "-s",
            "opt": "s3://ghrcsbxw-public/dmrpp_config/file.config",
            "download": "true"
          },
          {
            "flag": "-c",
            "opt": "s3://ghrcsbxw-public/aces1cont__1/aces1cont_2002.212_v2.50.tar.cmr.json",
            "download": "false"
          }
        ]
      }
    }
  }
}

opt is the value that will come after the flag, if provided with "download": "true" the value will be ignored and the file provided will be downloaded and used with the flag. If the opt is provided with "download": "false" or without download the value of opt will be used as a letteral string in get_dmrpp executable. We are supporting HTTP and s3 protocols.

Via Cumulus Workflow configuration

If you want the same dmrpp config to apply to multiple collections that use the same workflow, the configuration can be placed in the workflow at ${StepName}.Parameters.cma.task_config.dmrpp instead of in each collection at config.meta.dmrpp:

   "HyraxProcessing": {
      "Parameters": {
        "cma": {
          "event.$": "$",
          "task_config": {
            ...
            "dmrpp": {
              "dmrpp_regex" : "^.*.H6",
              "options": [
                {
                  "flag": "-M"
                },
                {
                  "flag": "-s",
                  "opt": "s3://ghrcsbxw-public/dmrpp_config/file.config",
                  "download": "true"
                },
                {
                  "flag": "-c",
                  "opt": "s3://ghrcsbxw-public/aces1cont__1/aces1cont_2002.212_v2.50.tar.cmr.json",
                  "download": "false"
                }
              ]
            }
          }
        }
      },

    ...
    }

As with other variables in the JSON template file, the dmrpp config can be set in a terraform variable:

"task_config": {
  ...
  "dmrpp": ${jsonencode(dmrpp_config)}
}

If dmrpp configuration is set on the collection and in the workflow, any keys in the collection's configuration will override those keys in the workflow's. This means, for example, if you want all collections processed with a given workflow to use the same options but different dmrpp_regex, the workflow config can set options and each collection can set dmrpp_regex to get the desired behavior.

Supported get_dmrpp configuration

Via env vars

Create a PAYLOAD environment variable holding dmrpp options

PAYLOAD='{"dmrpp_regex": "^.*.nc4", "options":[{"flag": "-M"}, {"flag": "-s", "opt": "s3://ghrcsbxw-public/dmrpp_config/file.config","download": "true"}]}'

dmrpp_regex is optional to override the DMRPP-Generator regex

Generate DMRpp files locally without Hyrax server

generate-validate-dmrpp now uses docker compose v2. Please update to
docker compose v2 or you will get the error
/bin/sh: 1: docker compose: not found

$generate-validate-dmrpp --help
usage: generate-validate-dmrpp [-h] -p NC_HDF_PATH [-prt PORT] [-pyld PAYLOAD] [-vldt VALIDATE]

Generate and validate DMRPP files.

optional arguments:
  -h, --help            show this help message and exit
  -p NC_HDF_PATH, --path NC_HDF_PATH
                        Path to netCDF4 and HDF5 folder
  -prt PORT, --port PORT
                        Port number to Hyrax local server
  -pyld PAYLOAD, --payload PAYLOAD
                        Payload to execute get_dmrpp binary
  -vldt VALIDATE, --validate VALIDATE
                        Validate netCDF4 and HDF5 files against OPeNDAP local server

The folder <absolute/path/to/nc/hdf/files> should contain netCDF and/or HDF files

generate-validate-dmrpp -p <absolute/path/to/nc/hdf/files> -vldt false

Generate DMRpp files locally with Hyrax server (for validation)

generate-validate-dmrpp -p <absolute/path/to/nc/hdf/files>
A prompt will ask you to visit localhost:8080
# If you want to change the default port run the command with
generate-validate-dmrpp -p <absolute/path/to/nc/hdf/files> -prt 8889
Now you can validate the result in localhost:8889

Generate missing metadata for non-netcdf compliant data (the -b switch)

generate-validate-dmrpp -p <absolute/path/to/nc/hdf/files> -pyld $PAYLOAD

or

docker run --rm -it --env-file ./env.list -v <absolute/path/to/nc/hdf/files>:/workstation ghrcdaac/dmrpp-generator

where PAYLOAD contains your flags and switches

PAYLOAD={"options":[{"flag": "-M"}, {"flag": "-u", "opt": "/usr/share/hyrax"}]}
