To open new port for new service on the instance, click Project -> Network -> Security Groups and click "Create Security Group".

By default on the new group you will have two Egress (outgoing) rules, for ipv4 and ipv6.

You need to create new Ingress (incoming) rule that should look like this:

Ingress    IPv4    TCP    80 (HTTP)    0.0.0.0/0

After creating the new Security Group you have to add it to your instance.

In the instance settings click "Security Groups" and add your newly created Security Group to your instance.

S3FS in Linux

In instances started from Linux images created after March 14,2020, /eodata is automatically mounted after adding the "eodata" network to your VM.

The /eodata mount runs as a service and can be restarted by executing the command:

sudo systemctl restart eodata.mount

and the status can be checked by executing:

sudo systemctl status eodata.mount

In instances created before March 14/2020, /eodata is mounted using the /etc/fstab file and can be remounted by executing commands below:

sudo umount -lf /eodata
sudo mount /eodata

NFS in Windows

In Windows:

Run CMD (Command Prompt) with administrator privileges.

Open START menu and type "CMD". Right click on the top result and select Run as Administrator.

Type:

route add 10.97.0.0/16 10.11.0.1

and confirm by pressing Enter.

The run script "mount eodata" from desktop.

NFS in Linux

If you want to mount eodata in Linux using NFS, you should stop the S3FS eodata.mount service:

sudo systemctl stop eodata.mount

Modify /etc/fstab and uncomment the line:

nfs.eodata.cloudferro.com:/eodata/repository /eodata nfs ro,noauto,_netdev 0 0

Save /etc/fstab and invoke:

sudo mount /eodata

If you have problems with access to eodata try the following:

install arping:

in CentOS

in Ubuntu:

check the name of the interface connected to eodata network:

based on the response, find the number of  the interface of 10.111.x.x (eth<number> or ens<number>)

after that invoke the following commands:

in CentOS:

in Ubuntu:

Next ping data.cloudferro.com again. If you receive answers, remount the resource:

a) Using web browser console

1. Open your web browser and enter https://finder.creodias.eu/www/ in the address field.

2. Click on “Log In” button located in the upper-right-corner.

3. Fill in the blanks with your e-mail address and password.

4. Press “Login”.

5. Click somewhere on the site with the right mouse button and choose “Inspect Element”.

6. Change your view side from Inspector to Console.

7. Click on the white space beside the blue arrow to start typing.

8. Type in keycloak.token and press enter in order to generate your token.

b) By query with cURL

This case has been presented in the How to order products using Finder API already. CURL is a tool to send data to the server using several protocols such as HTTP. In this example, the output is being filtred by grep and awk commands to obtain a token. In the Linux operating system it's being seen as environmental variable KEYCLOAK_TOKEN.

export KEYCLOAK_TOKEN=$(curl -d 'client_id=CLOUDFERRO_PUBLIC' \
                             -d "username=${OS_USERNAME}" \
                             -d "password=${OS_PASSWORD}" \
                             -d 'grant_type=password' \
                             'https://auth.creodias.eu/auth/realms/DIAS/protocol/openid-connect/token' | \
                             python -m json.tool | grep "access_token" | awk -F\" '{print $4}')

c) By Python script

import json
import requests

def get_keycloak(username: str, password: str) -> str:
    data = {
        "client_id": "CLOUDFERRO_PUBLIC",
        "username": username,
        "password": password,
        "grant_type": "password",
    }
    try:
        r = requests.post(
            "https://auth.creodias.eu/auth/realms/DIAS/protocol/openid-connect/token",
            data=data,
        )
        r.raise_for_status()
    except Exception as e:
        raise Exception(
            f"Keycloak token creation failed. Reponse from the server was: {r.json()}"
        )
    return r.json()["access_token"]

keycloak_token = get_keycloak(username, password)
