SENTINEL-1 (SAR) framework

This repo consists of a SAR product generation infrastructure designed for SLA enforcement. It is packaged in an Nuvla application. Its image processing job are done via the call of a relative app namely SAR_app. The main run starts an ELK stack and an Flask REST server which is the interface for job request.

Prerequisites

In order to successfully execute the application, you should have:

1. An account on Nuvla. Follow this link where you'll find how to create the account.

2. Cloud credentials added in your Nuvla user profile

   

3. Python >=2.6 and <3 and python package manager pip installed. Usually can be installed with sudo easy_install pip.

4. SlipStream python ss-client installed: pip install slipstream-client.

Instructions

1. Clone this repository with

   $ git clone https://github.com/SixSq/SAR-framework.git
   

2. Set the environment variables

   $ export SLIPSTREAM_USERNAME=<nuv.la username>
   $ export SLIPSTREAM_PASSWORD=<nuv.la password>
   

   and run the SAR framework on Nuvla with

   $ ./SAR_server_run.sh
   

3. Wait for the 'ready' state

4. Recover the server's ip and start working with it !

- Initialization with benchmarking specs and product:

```
curl -H "Content-Type: application/json" -X POST http://<server_ip>/dmm/init -d
'{
     "specs_vm": {
       "mapper": [4, 16000, 100],
       "reducer": [1, 1000, 100]
        },
     "product_list": [
       "S1A_IW_GRDH_1SDV_20151226T182813_20151226T182838_009217_00D48F_5D5F",
       "S1A_IW_GRDH_1SDV_20160424T182813_20160424T182838_010967_010769_AA98"
       ],
     "result": {
        "s3_credentials": {
              "host": "<s3 endpoint>",
              "bucket": "<bucket name>",
              "key": "xxx",
              "secret": "yyy"}}
     }
 }'
  ```


- Product generation with SLA:

```
curl -H "Content-Type: application/json" -X POST http://<server_ip>/dmm/run -d
 '{
   "SLA":{
     "requirements": [
                  <Time bound>,
                   <OFFER>], # still hardcoded to "CannedOffer_1"
      "product_list": [
            "S1A_IW_GRDH_1SDV_20151226T182813_20151226T182838_009217_00D48F_5D5F",
            "S1A_IW_GRDH_1SDV_20160424T182813_20160424T182838_010967_010769_AA98"
            ]
        },
    "result": {
        "s3_credentials": {
              "host": "<s3 endpoint>",
              "bucket": "<bucket name>",
              "key": "xxx",
              "secret": "yyy"}}
