Develop a re-usable installation method for the SNAP toolbox #13

Closed agstephens closed 3 years ago

agstephens commented 3 years ago

The SNAP toolbox is a collection of tools used for working with ESA satellite data, such as those from the Sentinel missions.

We would like to install SNAP under /apps/jasmin/supported/ (as long as it is not too difficult to install/maintain). We probably do not want to install it as part of extra-sci-packages unless there is a good reason to do so.

Here is the download location for the installer:

http://step.esa.int/main/download/snap-download/

This is a little basic install guide:

https://www.gis-blog.com/how-to-install-esa-snap-on-ubuntu-linux/

Many users will want to use the python API, snappy. Instructions for setting up the SNAP python API are here:

https://senbox.atlassian.net/wiki/spaces/SNAP/pages/19300362/How+to+use+the+SNAP+API+from+Python

Apparently, multiple users will need to be able to hook into the install and point towards it with an environment variable when loading the snappy module. ESA likely has an internal answer to this problem, so if we run into problems we should get in touch with them.

The task is:

@alaniwi - NOTE: If you have spent more than 2 days on this then leave it to discuss further when @agstephens gets back from leave.

It is installed and I have written a detailed document explaining how to repeat the installation on JASMIN. The document also explains why a scripted install is not really possible.

See /apps/jasmin/supported/snap/INSTALLATION/README-snap-on-jasmin

It will run better when the mesa-dri-drivers RPM is provided on the sci machines (as seen on sci2-test where I've installed it), and I've created a separate ticket to add the relevant meta RPM.

Part of the build process needs to be on test machine because the production sci machines don't have JDK in the OS -- they have JRE. Maybe we should provide the corresponding JDK RPM also via extra-sci-packages. Though there is also an argument for providing Java via Jaspy.

Happy to close!
