This is the main repository for the IOOS Glider DAC site, scripts, and tools.
Detailed documentation on contact information, file format, user account registration, deployment registration and file submission can be found on the IOOS National Glider DAC wiki.
Inquires should be sent to glider.dac.support@noaa.gov
To create a development build, install Docker and Docker Compose.
Run docker-compose up -d to run the initial setup.
Glider DAC is driven by NetCDF data, so if you are not intending to populate a development copy with your own glider data, you'll likely want to request read-only S3 access for the NetCDF data and database contents without password by emailing a request to glider.dac.support@noaa.gov and explaining your use case.
Once this is in place, optionally create a folder where you wish to sync data
as a bind mount for docker and then in the .env file, set the DATA_VOLUME
environment variable to match the local path of the data directory. If using a bind mount, ensure that the corresponding directories for the submission and served ERDDAP data
exist with the filesystem hierarchy. By default in the configuration, these
are submission and data/priv_erddap by default. Issuing the following command in shell will create the
necessary directories:
mkdir -p /<DESTINATION_DATA_DIRECTORY>/submission /DESTINATION_DATA_DIRECTORY/data/priv_erddap
The default compose setup comes with a named Docker volume, so it is also an
option to copy directly to this mount using docker cp or moving the files to
the volume location reported by docker volume inspect gliderdac_data_volume.
Create an empty file named datasets.xml in the project root directory glider-dac so that
ERDDAP can populate the datasets when running the job to add XML dataset entries
to this file.
Next, comment out the line - ./config.local.yml:/glider-dac/config.local.yml in the docker-compose.yml file. Look under volumes: in the glider-dac-providers-app: services section. This step is necessary to setting up the correct configuration for the providers app.
Then, run the aws s3 sync command to fetch the data, with s3://ioosngdac/submission/
as the source directory. It is recommended to fetch a subset of the data using the --include option.
Here, the command fetches NetCDF files with "202312" in the name, corresponding
to glider profiles which started in December 2023:
aws s3 sync s3://ioosngdac/submission/ <DESTINATION_DATA_DIRECTORY>/submission --exclude '*' --include '*202312*.nc'
`
While the data are downloading from the s3 bucket, copy one of the nightly database backups and restore it to the database:
mkdir backup_dir
cd backup_dir
aws s3 cp s3://ioosngdac/backups/2023-12-29-gliderdac-mongodb.tar.gz .
tar xf 2023-12-29-gliderdac-mongodb.tar.gz
docker cp mongo_dumps mongo:/data/
docker exec -w /data mongo sh -c "mongorestore mongo_dumps/dump && rm -rf mongo_dumps"
rm -rf mongo_dumps
Once these steps are run, you should be able to navigate to the development server at http://localhost:3000 and view various deployments.
If desired, create a user with docker exec -it glider-dac-providers-app python usertool.py set <username>
to add a user and set the password. If creating a user with the same name as one of the restored users in the database backup,
this will set the password and allow you to perform editing actions once logged in as the user through the application.
