NASA Global Imagery Browse Services (GIBS)

This software is part of NASA GIBS OnEarth (https://github.com/nasa-gibs/onearth) and was developed at the Jet Propulsion Laboratory.

OnEarth-Boxes

OnEarth-Boxes is a system that creates VM images for use in running, testing, and experimenting with the OnEarth and MRF tools. It uses Packer to produce a variety of pre-built VMs in different formats.

Boxes comes with some sample imagery and some pre-configured endpoints for use with testing and development.

What's in the Boxes?

OnEarth-Boxes comes pre-configured with several sample layers in 4 separate projections. There are OpenLayers endpoints for testing with WMTS, as well as TWMS/KML and Mapserver endpoints.

All the source code for both MRF and OnEarth is included, and all the utilities are pre-installed, including the GDAL MRF extensions.

To get started with OnEarth-Boxes once you've created a VM image and have it running, go to <onearth-boxes_vm_url>/onearth/demo.

Requirements

Creation of an OnEarth-Boxes image requires Packer to be installed on your computer.

Creating an OnEarth VM

To create a VM, use the packer build <template.json> command. There are .json template files for several different kinds of builds. See below for details.

Build Options

To specify options for the build process, use the -var tag, for example:

packer build -var "host_port=8080" oe-vagrant.json

Available Options

host_port - in order for the OnEarth TWMS endpoint to work, Apache in the VM needs to be configured to use the same port within the VM as will be used on the host machine. Defaults to 8080.

In other words, if you're planning to access the VM under localhost:8888, it works best if Apache within the VM also uses that port. This option automatically configures Apache to use the specified port.

Builders

The following build templates are included:

• oe-virtualbox.json -- A VirtualBox image
• oe-vagrant.json -- A VirtualBox image packaged as a Vagrant box
• oe-vmware.json -- A VMWare image
• oe-parallels.json -- A Parallels image
• oe-docker.json -- A Docker container

Note for building Docker containers

Currently, Packer only supports building Docker containers in Linux. You'll need to install Docker and Packer and make sure the Docker daemon is active before running the Packer build process.

Vagrant info

Using Vagrant is one of the easiest ways to get started with the OnEarth demo VM.

Step 1: Install Vagrant

Vagrant is available for Mac, Windows, and Linux. It's free and requires VirtualBox.

Step 2: Build the Vagrant box with Packer

Run the default Packer command: packer build oe-vagrant.json within the root of this repo. See above for options to customize the install.

Note that the build process compiles a lot of software and generates some MRF imagery, so it can take quite a while.

Step 3: Add the Vagrant box

After the Packer build process is complete, go to the builds directory that will be created in the root of the repo and add the box with this command: vagrant box add --name=onearth-demo builds/virtualbox-onearth.box

Once the Vagrant box is added, you can create multiple new virtual machines using that box as a base. It's not necessary to rebuild with Packer each time.

Step 4: Create a Vagrantfile

From any directory you like, type the command vagrant init, which will set up a sample Vagrantfile. Open the Vagrantfile and make sure the following lines are present:

config.vm.box = "onearth-demo"

config.vm.network "forwarded_port", guest: <chosen_port>, host: <chosen_port>

Step 5: Start the VM

Use the vagrant up command to boot the VM. The demo should now be available at: localhost:<chosen_port>/onearth/

You can use the vagrant ssh command to open a shell inside the VM. The directory that contains your Vagrantfile is mapped to /vagrant within the VM by default.

The username and password within the Vagrant VM are vagrant and vagrant

Docker Info

Docker is a great way to run OnEarth as a standalone process.

To run OnEarth within a Docker container, first use Packer to build the Docker image (packer build oe-docker.json).

Then, to run a container, use the docker run command. You'll want to follow something like this:

docker run -d -p <host_port>:<container_port> nasagibs/onearth:1.3.5 apachectl -D FOREGROUND

So to run a Docker container that's accessible via port 8080 on the host machine, run:

docker run -d -p 8080:8080 nasagibs/onearth:1.3.5 apachectl -D FOREGROUND

You can then view the OnEarth demo page by pointing your browser to: http://localhost:8080/onearth/.
