Building and running

make && _rel/executive/bin/executive

SSH access

Configuration

Run deps/erl_sshd/make_keys. This will create:

• create a system key as `priv/erl_sshd/ssh_host_rsa_key',
• create a public and private user key in the top directory
• add the created public user key to the priv/erl_sshd/authorized_keys.

Adjust listen port and user/passwords in the config/sys.config file:

 {erl_sshd, [
             {app, executive},
             {port, 11122},
             {passwords, [{"alice","secret"}]}
            ]}

Remember to re-generate release after changing/creating the keys/sys.config.

Detailed information can be find in the erl_sshd README.

Access using keys

To access running Executive node via keys run in the top directory:

ssh HOSTNAME -p 111222 -i id_rsa

Access via user/password

ssh alice@HOSTNAME -p 11122

Example

Publishing Physical Host

Ports = 
   [{"PP1", #{mac_address => "00:00:00:00:01:AA", interface => "eth0"}},
    {"PP2", #{mac_address => "00:00:00:00:01:AB", interface => "eth1"}}].
executive:publish_physical_host("ClusterPatchP", "PH1", Ports).

Publishing Virtual Host

It will be attached to the previously pbulished Physical Host PH1.

VirtualPorts = 
   [{"VP1", #{mac_address => "00:00:00:00:01:AA", interface => "eth0"}},
    {"VP2", #{mac_address => "00:00:00:00:01:AB", interface => "eth1"}}].
VifPorts = 
   [{"VP1.1", #{vp_to_bound => "VP1", interface => "vif1.1"}},
    {"VP1.2", #{vp_to_bound => "VP2", interface => "vif1.2"}}].
executive:publish_virtual_host("PH1", "PH1/VH1", VirtualPorts, VifPorts).

Publishing OpenFlow Switch

It will be attached to previously published Virtual Host VH1.

Ports = 
   [{"OFP1", #{vp_to_bound => "VP1"}},
    {"OFP2", #{vp_to_bound => "VP2"}}].
executive:publish_of_switch("PH1/VH1", "PH1/VH1/OFS1",  Ports).

Publishing Endpoint

It will be attach to the previously published Virtual Host VH1 assuming that the OpenFlow Switch OFS1 was not published.

executive:publish_endpoint("PH1/VH1", "EP1", "VP1").

Publishing another Physical Host and linking it to the first one

The hosts will be connected via PP1 Physcial Ports on each host.

Ports = 
   [{"PP1", #{mac_address => "00:00:00:00:01:AA", interface => "eth0"}},
    {"PP2", #{mac_address => "00:00:00:00:01:AB", interface => "eth1"}}].
executive:publish_physical_host("ClusterPatchP", "PH2", Ports).
executive:bound_physical_hosts("PH1", "PP1", "PH2", "PP1").
