Foreman Smart Proxy provides a "REST":http://en.wikipedia.org/wiki/Representational_State_Transfer API, communicating via JSON.  For providers that take POST requests, some take form parameters as inputs (var=1&var=2), others may take JSON. Please refer to this document for latest information about Foreman Smart Proxy API.

h2. Manually Calling the API
66
67
The API can be manually tested out using curl.  GET types can be retrieved like any other URL.  This one, for example, will return the HTML formatted page with the list of features enabled on the proxy.
68
69 1 Ohad Levy
<pre>
70
curl http://localhost:8443/features
71
</pre>
72
73 14 Michael Coulter
The results can also be returned as JSON if you set an appropriate Accept header.
74
75
<pre>
76
curl -H "Accept: application/json" http://localhost:8443/features
77
</pre>
78
79 1 Ohad Levy
POST URLs, used to create objects or trigger actions, need to have the parameters passed in via the -d argument.  This curl command line will trigger a puppetrun on server.example.com.
80
<pre>
81
curl -d 'nodes=server.example.com' http://localhost:8443/puppet/run
82 11 Michael Coulter
</pre>
83
84
This curl command line will add an A record for server.example.com with ip address of 10.1.2.5.
85
<pre>
86
curl -d 'fqdn=servers.example.com&value=10.1.2.5&type=A' http://localhost:8443/dns/
87 5 Frank Sweetser
</pre>
88
89 22 Johan Sunnerstig
This curl command line will remove the A record added above.
90
<pre>
91
curl -XDELETE http://localhost:8443/dns/servers.example.com
92
</pre>
93
94 5 Frank Sweetser
Multiple post options may be specified by repeating the -d argument.
95
<pre>
96
curl -d 'prefix=boot/CentOS-5-x86_64' -d 'path=http://yourlocalmirrorhere/pub/centos/5/os/x86_64/images/pxeboot/vmlinuz'  http://localhost:8443/tftp/fetch_boot_file
97
</pre>
98
99
When you are creating an object, the identifier for the object is typically passed in as part of the URL, rather than as a POST value.  For example, this will create a PXE boot configuration file for a host with MAC address 00:11:22:33:44:55, and will just put "Hello World" as the contents of the file.  (A real world example would, of course, substitute a valid PXE boot configuration in the string.)
100
101
<pre>
102
curl -d 'syslinux_config=Hello World' http://localhost:8443/tftp/00:11:22:33:44:55
103
</pre>
104
105
In order to delete objects, you use the same URL as in the original creation, but pass it not POST values, and use the DELETE HTTP method instead of POST.  This will delete the PXE boot configuration file created above.
106
107
<pre>
108 1 Ohad Levy
curl -X DELETE http://localhost:8443/tftp/00:11:22:33:44:55

h2. BMC Controls 
112
113
Summary
114
The smart-proxy can now control BMC devices through the use of the IPMI protocol.  The smart proxy utilizes ipmitool and freeipmi to control your BMC devices through the network.  
115
116
h3. Prerequisites
117
118
In order to control the BMC device using the smart proxy you must perform the following actions:
119
120
1. Enable bmc support in the settings.yml file
121
2. Install rubyipmi gem, 
122
3. Install freeipmi, and/or ipmitool either from source or package
123
4. The bmc device must be setup on the network with login credentials
124
5. Smart proxy must be able to reach the bmc device through the network
125
126
h3. Using Parameters with the BMC API
127
128
1. When using the bmc api, you must send the credentials of the bmc device using Http Basic Authorization
129
2. If you wish to override the default bmc provider for a particular BMC device please specify in the http parameter (bmc_provider) Valid options are ipmitool and freeipmi
130
3. Some api calls have optional parameters, leaving the action blank on some api calls will return valid actions and options.
131
132 17 Corey Osman
h3. BMC Security
133 16 Corey Osman
134
Its important to note that at this time the bmc api does not encrypt your credentials.  Your credentials are sent in the clear to the smart proxy and then used on the command line to execute the local command.
135
In order to achieve some level of security it is important that your smart proxy use https.  Using https will ensure that your credentials are sent via the encrypted https channel.  Additionally, by default the bmc api 
136
will never expose your credentials to prying eyes via logs or process checks.  The local bmc commands will be run with the credentials placed in a random file which is deleted upon every call and cannot be opened
137
by any other user.

h3. Examples
140
141
returns boolean if the power is off  (Note this only occurs when using GET
142
<pre>
143
curl -vks --data 'bmc_provider=freeipmi' 'http://127.0.0.1:8443/bmc/192.168.1.16/chassis/power/off' -X GET -u admin:password  => {"action":"off","result":true}
144
</pre>
145
146
returns status when the power is turned off  (Note this only occurs when using PUT)
147
<pre>
148
curl -vks --data 'bmc_provider=freeipmi' 'http://127.0.0.1:8443/bmc/192.168.1.16/chassis/power/off' -X PUT -u admin:password  => {"action":"off","result":"192.168.1.16: ok\n"}
149
</pre>
150
151
if you can't remember the basic bmc api actions you just leave things blank and the proxy will try to help you out.
152
<pre>
153
curl -vks --data 'bmc_provider=freeipmi' 'http://127.0.0.1:8443/bmc/192.168.1.16/chassis' -X GET -u admin:password => {"actions":["power","identify","config"]}

h4. Troubleshooting
158
159
If you have some weird BMC issue you can have a look at the log if your using the latest smart proxy >= 1.9.  Starting with Rubyipmi 0.9.0 it will not generate a logs with all the commands and responses it runs.
160
<pre>
161
curl -vks --data 'bmc_provider=freeipmi' 'http://127.0.0.1:8443/bmc/192.168.1.16/chassis/power/off' -X GET -u admin:password  => {"action":"off","result":true}

165
</pre>
166
167
Optionally, if you want to separate those logs you can specify the provider log level in the bmc.yml settings file (smart proxy >= 1.9) and Rubyipmi will manage a independent log file in /tmp/rubyipmi.log with the same information.
168
Set this in your smart_proxy settings.d/bmc.yaml
169
<pre>
170
:enabled: true

172
</pre>

Now you can just watch the rubyipmi events instead of other smart_proxy logs

h4. New Host
191
192
The FreeIPA returns the raw XMLRPC JSON when creating a host, however the only relevant key is "randompassword."  Any other Realm providers at a minimum should return an OTP for a new host.
193
194
Example full output from FreeIPA:

</pre>
224
225
h4. Update Host
226
227
* "rebuild=true" is passed for any host being rebuilt in order to know whether to revoke any outstanding certificates, etc.  A new randompassword should be issued.
228
229
* Foreman also triggers an update if the "userclass" is being updated.  You should not return a new one-time password for this, only update the attribute (if desired) and return 200.  If nothing needs to be updated, you should return resposen 200 and this JSON
230
231
<pre>
232
{"message" => "nothing to do"}
233

The Smart Proxy will return 404 if not found, 400 for any other error.
