usage() {
cat << EOT
Usage : ${__ScriptName} [options] <install-type> <install-type-args>
Installation types:
- stable (default)
- daily (ubuntu specific)
- git
Examples:
$ ${__ScriptName}
$ ${__ScriptName} stable
$ ${__ScriptName} daily
$ ${__ScriptName} git
$ ${__ScriptName} git develop
$ ${__ScriptName} git v0.17.0
$ ${__ScriptName} git 8c3fadf15ec183e5ce8c63739850d543617e4357
Options:
-h Display this message
-v Display script version
-n No colours.
-D Show debug output.
-c Temporary configuration directory
-k Temporary directory holding the minion keys which will pre-seed
the master.
-M Also install salt-master
-S Also install salt-syndic
-N Do not install salt-minion
-C Only run the configuration function. This option automatically
bypasses any installation.
-P Allow pip based installations. On some distributions the required salt
packages or its dependencies are not available as a package for that
distribution. Using this flag allows the script to use pip as a last
resort method. NOTE: This works for functions which actually implement
pip based installations.
-F Allow copied files to overwrite existing(config, init.d, etc)
-U If set, fully upgrade the system prior to bootstrapping salt
-K If set, keep the temporary files in the temporary directories specified
with -c and -k.
