List Cloud Networks using Rackspace API

In the previous chapter we learnt how to add networks using the API. It’s really simple, its basically a network and label placeholder. But what about viewing the networks we have after we’ve made some? This is pretty simple to confirm.

I have simplified the code a bit to make it easier to read.

#!/bin/sh

USERNAME='mycloudusername'
APIKEY='mycloudapikey'
ACCOUNT_NUMBER=10010101
API_ENDPOINT="https://lon.networks.api.rackspacecloud.com/v2.0/$ACCOUNT_NUMBER"

TOKEN=`curl https://identity.api.rackspacecloud.com/v2.0/tokens -X POST -d '{ "auth":{"RAX-KSKEY:apiKeyCredentials": { "username":"'$USERNAME'", "apiKey": "'$APIKEY'" }} }' -H "Content-type: application/json" |  python -mjson.tool | grep -A5 token | grep id | cut -d '"' -f4`

curl -i -X GET https://lon.networks.api.rackspacecloud.com/v2.0/networks -H "X-Auth-Token: $TOKEN" 

Output

# ./list-networks.sh

{"networks": [{"status": "ACTIVE", "subnets": [], "name": "Isolatednet", "admin_state_up": true, "tenant_id": "10010101", "shared": false, "id": "ae36972f-5cba-4327-8bff-15d8b05dc3ee"}], "networks_links": [{"href": "http://localhost:9696/v2.0/networks?marker=ae36972f-5cba-4327-8bff-15d8b05dc3ee&page_reverse=True", "rel": "previous"}]}

Pretty cool, but the format kind of sucks, I forgot to use python |-mjson.tool or jq to format the json output. Lets do that now by adding the line to the end of the curl -i line.

Now the output is nice:

{
    "networks": [
        {
            "admin_state_up": true,
            "id": "ae36972f-5cba-4327-8bff-15d8b05dc3ee",
            "name": "Isolatednet",
            "shared": false,
            "status": "ACTIVE",
            "subnets": [],
            "tenant_id": "10010101"
        }
    ],
    "networks_links": [
        {
            "href": "http://localhost:9696/v2.0/networks?marker=ae36972f-5cba-4327-8bff-15d8b05dc3ee&page_reverse=True",
            "rel": "previous"
        }
    ]
}

The complete code will look like;

#!/bin/sh

USERNAME='mycloudusername'
APIKEY='mycloudapikey'
ACCOUNT_NUMBER=10010101
API_ENDPOINT="https://lon.networks.api.rackspacecloud.com/v2.0/$ACCOUNT_NUMBER"

TOKEN=`curl https://identity.api.rackspacecloud.com/v2.0/tokens -X POST -d '{ "auth":{"RAX-KSKEY:apiKeyCredentials": { "username":"'$USERNAME'", "apiKey": "'$APIKEY'" }} }' -H "Content-type: application/json" |  python -mjson.tool | grep -A5 token | grep id | cut -d '"' -f4`

# with header no formatting
#curl -i -X GET https://lon.networks.api.rackspacecloud.com/v2.0/networks -H "X-Auth-Token: $TOKEN"
# without header with formatting
curl -X GET https://lon.networks.api.rackspacecloud.com/v2.0/networks -H "X-Auth-Token: $TOKEN" | python -mjson.tool
