Wattson

The WaTTS (INDIGO Token Translation Service) command line client

Quickstart

Once installed using wattson is straight forward:

The next lines will set up the connection and check the supported issuer:

export WATTSON_URL=https://tts-dev.data.kit.edu
wattson lsprov

The output will be similar to:

connecting to https://tts-dev.data.kit.edu/api/v2/ using protocol version 2

*** WARNING: either access token or issuer has not been specified ***

retrieving provider list:
Provider [iam][ready] INDIGO Datacloud Identity and Access Management (IAM) (https://iam-test.indigo-datacloud.eu/)
Provider [hbp][ready] Human Brain Project (HBP) (https://services.humanbrainproject.eu/oidc/)
Provider [eudat][ready] EUDAT (b2access) (https://b2access.eudat.eu:8443/oauth2)
Provider [egi][ready] European Grid Infrastracture (Development) (https://aai-dev.egi.eu/oidc/)
Provider [google][ready] Google, the well known search giant (https://accounts.google.com)

The output shows the list of supported provider:

• their id
• wether they are ready or not
• a descriptive name
• the issuer url

Also a warning is shown that the access token and isuer need to be set. In this example we will use 'iam'. Log in at the web interface of TTS using IAM. Then select 'show access token' and copy the content of the dialog. The following line will set up the authorization for the command line client and request the list of services:

export WATTSON_TOKEN=<paste the copied text from the dialog here>
export WATTSON_ISSUER=https://iam-test.indigo-datacloud.eu/
wattson lsserv

The output should be similar to:

connecting to https://tts-dev.data.kit.edu/api/v2/ using protocol version 2
retrieving service list:

    Empty Parameter Set (allows basic request)


Service [aarc_ssh][enabled/NOT AUTHORIZED] Ssh Key Deployment on multiple VMs
   Your authorisation is insufficient for this service. This may be due to missing group membership or due to a too low Level of Assurance (LoA) (Yes, we already support that kind of stuff ;D)
 - credenitals: 0/1
 - parameter sets:
    Parameter Set:
      MANDATORY Parameter 'public key' [pub_key]: the public key to upload to the service (textarea)

The warning of the missing token/issuer is gone. The output shows the list of all services:

• the id
• wether the service is enabled
• wether one is authorized to use that service
• a description of the service
• the number of credentials one has and max. allowed
• the parameter sets (mainly used for development)

Requesting a credential simply works with the command 'request' and the service id:

wattson request info

the output should be similar to:

requesting credential for service [info]:
Credential [f9dbb0e0-9e3e-4065-9fee-8ac30387d2b4]:
[ TTS version (text)] => 1.0.0-rc4
[ TTS userid (text)] => eyJpc3N1ZXIiOiJpc3MiLCJzdWJqZWN0Ijoic3ViIn0
[ TTS userid (decoded) (text)] => {"issuer":"iss","subject":"sub"}
[ family_name (text)] => Wegh
[ Name (text)] => Bas Wegh
[ Issuer (text)] => iss
[ Gender (text)] => M
[ preferred_username (text)] => bwegh
[ updated_at (text)] => Wed Aug 31 09:06:43 UTC 2016
[ given_name (text)] => Bas
[ Groups (textarea)] => [<<"Users">>]
[ organisation_name (text)] => indigo-dc
[ Subject (text)] => sub
[ json object (textarea)] => {
    "action": "request",
    "conf_params": {},
    "cred_state": "undefined",
    "params": {},
    "tts_userid": "eyJpc3N1ZXIiOiJpc3MiLCJzdWJqZWN0Ijoic3ViIn0",
    "tts_version": "1.0.0-rc4",
    "user_info": {
        "family_name": "Wegh",
        "gender": "M",
        "given_name": "Bas",
        "groups": [
            "Users"
        ],
        "iss": "iss",
        "name": "Bas Wegh",
        "organisation_name": "indigo-dc",
        "preferred_username": "baswegh",
        "sub": "sub",
        "updated_at": "Wed Aug 31 09:06:43 UTC 2016"
    }
}

Now you can use that information/credential, once you do not need it anymore you need to revoke it using the credential id, shown in the first line:

wattson revoke f9dbb0e0-9e3e-4065-9fee-8ac30387d2b4

the output should look like:

revoking credential [f9dbb0e0-9e3e-4065-9fee-8ac30387d2b4]:
credential sucessfully revoked
