uR
Parses opts and generates a list of master (host,port) addresses.
By default looks for list of masters in opts['master'] and uses
opts['master_port'] as the default port when otherwise not provided.
To use this function to generate the cluster master list then
call with masters='cluster_masters' and port='raet_port' on a master
and
call with masters='cluster_masters' on a minion
Use the opts key given by masters for the masters list, default is 'master'
If parameter port is not None then uses the default port given by port
Returns a list of host address dicts of the form
[
{
'external': (host,port),
'internal': (host, port)
},
...
]
When only one address is provided it is assigned to the external address field
When not provided the internal address field is set to None.
For a given master the syntax options are as follows:
hostname [port]
external: hostname [port]
[internal: hostaddress [port]]
Where the hostname string could be either an FQDN or host address
in dotted number notation.
master.example.com
10.0.2.110
And the hostadress is in dotted number notation
The space delimited port is optional and if not provided a default is used.
The internal address is optional and if not provided is set to None
Examples showing the YAML in /etc/salt/master conf file:
1) Single host name string (fqdn or dotted address)
a)
master: me.example.com
b)
master: localhost
c)
master: 10.0.2.205
2) Single host name string with port
a)
master: me.example.com 4506
b)
master: 10.0.2.205 4510
3) Single master with external and optional internal host addresses for nat
in a dict
master:
external: me.example.com 4506
internal: 10.0.2.100 4506
3) One or host host names with optional ports in a list
master:
- me.example.com 4506
- you.example.com 4510
- 8.8.8.8
- they.example.com 4506
- 8.8.4.4 4506
4) One or more host name with external and optional internal host addresses
for Nat in a list of dicts
master:
-
external: me.example.com 4506
internal: 10.0.2.100 4506
-
external: you.example.com 4506
internal: 10.0.2.101 4506
-
external: we.example.com
- they.example.com

Parse hostname string and return a tuple of (host, port)
If port missing in hostname string then use default_port
If anything is not a valid then return None
hostname should contain a host and an option space delimited port
host port
As an attempt to prevent foolish mistakes the parser also tries to identify
the port when it is colon delimited not space delimited. As in host:port.
This is problematic since IPV6 addresses may have colons in them.
Consequently the use of colon delimited ports is strongly discouraged.
An ipv6 address must have at least 2 colons.
