NAME

t3c-preprocess - Traffic Control Cache Configuration preprocessor

SYNOPSIS

t3c-preprocess

[--help]

[--version]

DESCRIPTION

The 't3c-preprocess' app preprocesses generated config files, replacing directives with relevant data.

The stdin must be the JSON '{"data": <data>, "files": <files>}' where <data> is the output of 't3c-request --get-data=config' and <files> is the output of 't3c-generate'.

DIRECTIVES

The following directives will be replaced. These directives may be placed anywhere in any file, by either t3c-generate(1) or Traffic Ops Parameters.

__SERVER_TCP_PORT__ is replaced with the Server's Port from Traffic Ops; unless the server's
                    port is 80, 0, or null, in which case any occurrences preceded by a colon
                    are removed.

__CACHE_IPV4__      is replaced with the Server's IP address from Traffic Ops.

__HOSTNAME__        is replaced with the Server's (short) HostName from Traffic Ops.

__FULL_HOSTNAME__   is replaced with the Server's HostName, a dot, and the Server's DomainName
                    from Traffic Ops (i.e. the Server's Fully Qualified Domain Name).

__CACHEGROUP__      is replaced with the Server's Cachegroup name from Traffic Ops.

__RETURN__          is replaced with a newline character, and any whitespace before or after
                    it is removed.
