Start your Docker and login into your account. If you don't have installed follow these instructions: Docker Documentation
To log in from your terminal:
docker login Username: your_username Password: XXXX
Now pull the ViSUS on-demand image:
docker pull visus/ondemand
This container provides three services:
- the ViSUS Server
- conversion service (i.e., currently limited to NetCDF datasets)
- a simple Web viewer
How to run the Containter
You need to specify few simple settings:
- the port you want to use for the conversion service (internal 80)
- the port you want to use for the webviewer and data server (internal 42299)
- the folder containing the files to serve/convert (i.e., NetCDF files), this will be mapped to "/data/xml" in the container
- a folder to use for caching the multiresolution data for streaming, this will be mapped to "/data/idx" in the container
Quick start with some demo data:
# create directory for your input data mkdir -p $PWD/nc # create directory for your cache mkdir -p $PWD/idx # download a sample NetCDF dataset wget https://www.dropbox.com/s/jnhptd5vswaurem/test2d.nc -O ./nc/test2d.nc
Run the container:
docker run -it -p 80:80 -p 42299:42299 -v $PWD/nc:/data/xml -v $PWD/idx:/data/idx visus/ondemand
In this run command we mapped:
- port 80, used in the container for the data streaming and webviewer services
- port 42299, used in the container for the NetCDF data conversion service
How to visualize your data on the server
Go to the On-demand test page: http://localhost/ondemand.php. Note: replace "localhost" with your server name and port if you are running with custom settings.
In this page you will find the list of *.nc contained in the folder you provided. You can click on the corresponding "View" button to visualize your data. Note: if the dataset has not been already converted the request could take a few second since it will be converting on-demand.
