openEO EODC backend deployment via TOSCA

[andrea-manzi]

Cluster deployed via IM at https://openeo.62.217.83.68.nip.io/1.1.0/

Need to clarify the EGI Check-in used. I have setup via IM to use the EGI Check-in demo instance, is that automatically configured ? or only the Production instance is there by default?

I report here the exampels I shared via email to test the deployed back-end:

Anyway, the Eurac openEO development back-end uses the same code base (openeo-processes-dask) for the processes implementation, and this works against it (you can also try it):

import openeo
from openeo.metadata import CollectionMetadata
from openeo.processes import array_element

conn = openeo.connect('https://dev.openeo.eurac.edu').authenticate_basic("guest","changeme")

url = https://earth-search.aws.element84.com/v1/collections/sentinel-2-l2a
spatial_extent =  {"east": 11.40, "north": 46.52, "south": 46.46, "west": 11.25}
temporal_extent = ["2022-06-01", "2022-06-30"]
bands = ["red", "nir"]
s2_datacube = conn.load_stac(
    url=url,
    spatial_extent=spatial_extent,
    temporal_extent=temporal_extent,
    bands=bands
)

s2_datacube.metadata = CollectionMetadata({"cube:dimensions":{"time":{"type":"temporal"},"band":{"type":"bands"}}})

def NDVI(data):    
    b04 = data.array_element(label="red")
    b08 = data.array_element(label="nir")
    return (b08 - b04) / (b08 + b04)

ndvi = s2_datacube.reduce_dimension(dimension="band",reducer=NDVI)
ndvi_median = ndvi.reduce_dimension(dimension="time", reducer="median")
result_ndvi = ndvi_median.download("ndvi_eurac.nc")

When trying to use the deployed InterTwin openEO back-end I get the following error. It seems like it’s requiring authentication, which I’m unaware of.

Code to try:

import openeo
import requests
from openeo.metadata import CollectionMetadata
from openeo.processes import array_element

s = requests.Session()
s.verify = False
conn = openeo.connect('https://openeo.62.217.83.68.nip.io/1.1.0/',session=s)

url = https://earth-search.aws.element84.com/v1/collections/sentinel-2-l2a
spatial_extent =  {"east": 11.40, "north": 46.52, "south": 46.46, "west": 11.25}
temporal_extent = ["2022-06-01", "2022-06-30"]
bands = ["red", "nir"]
s2_datacube = conn.load_stac(
    url=url,
    spatial_extent=spatial_extent,
    temporal_extent=temporal_extent,
    bands=bands
)

s2_datacube.metadata = CollectionMetadata({"cube:dimensions":{"time":{"type":"temporal"},"band":{"type":"bands"}}})

def NDVI(data):    
    b04 = data.array_element(label="red")
    b08 = data.array_element(label="nir")
    return (b08 - b04) / (b08 + b04)

ndvi = s2_datacube.reduce_dimension(dimension="band",reducer=NDVI)
ndvi_median = ndvi.reduce_dimension(dimension="time", reducer="median")
result_ndvi = ndvi_median.download("ndvi_intertwin.nc")

error:

OpenEoApiPlainError: [422] {"detail":[{"loc":["header","authorization"],"msg":"field required","type":"value_error.missing"}]}

It would be nice to have a working example using batch jobs and getting the result in STAC. @SerRichard where will the result be stored? Is there a linked object storage to this openEO back-end?

@andrea-manzi I don't see Sean in the members, could you add him so that he can take part to the discussion?

[andrea-manzi]

I have invited Sean to the organization !

Hi @clausmichele

If you change the line:

conn = openeo.connect('https://openeo.62.217.83.68.nip.io/1.1.0/',session=s)

With this, the authentication works (but I get another errors)

token = "ey.........."
conn = openeo.connect('https://openeo.62.217.83.68.nip.io/1.1.0',session=s).authenticate_oidc_access_token(token)

To get the value of the token variable you can go here, and copy the value of the Access Token:
https://aai-demo.egi.eu/token/

[clausmichele]

For me, this returns the following error:

import openeo
import requests

token = "ey..."
s = requests.Session()
s.verify = False
conn = openeo.connect('https://openeo.62.217.83.68.nip.io/1.1.0',session=s).authenticate_oidc_access_token(token)
