Bootstrapping Salt
==================
Before `Salt`_ can be used for provisioning on the desired machine, the
binaries need to be installed. Since `Salt`_ supports many different
distributions and versions of operating systems, the `Salt`_ installation
process is handled by this shell script ``bootstrap-salt-minion.sh``. This
script runs through a series of checks to determine operating system type and
version to then install the `Salt`_ binaries using the appropriate methods.
Adding support for other operating systems
------------------------------------------
In order to install salt for a distribution you need to define:
To Install Dependencies, which is required, one of:
1. install_<distro>_<distro_version>_<install_type>_deps
2. install_<distro>_<distro_version>_deps
3. install_<distro>_<install_type>_deps
4. install_<distro>_deps
To install salt, which, of course, is required, one of:
1. install_<distro>_<distro_version>_<install_type>
2. install_<distro>_<install_type>
Optionally, define a minion configuration function, which will be called if
the -c|config-dir option is passed. One of:
1. config_<distro>_<distro_version>_<install_type>_minion
2. config_<distro>_<distro_version>_minion
3. config_<distro>_<install_type>_minion
4. config_<distro>_minion
5. config_minion [THIS ONE IS ALREADY DEFINED AS THE DEFAULT]
Also optionally, define a post install function, one of:
1. install_<distro>_<distro_versions>_<install_type>_post
2. install_<distro>_<distro_versions>_post
3. install_<distro>_<install_type>_post
4. install_<distro>_post
Below is an example for Ubuntu Oneiric:
install_ubuntu_1110_deps() {
apt-get update
apt-get -y install python-software-properties
add-apt-repository -y 'deb http://us.archive.ubuntu.com/ubuntu/ oneiric universe'
add-apt-repository -y ppa:saltstack/salt
}
install_ubuntu_1110_post() {
add-apt-repository -y --remove 'deb http://us.archive.ubuntu.com/ubuntu/ oneiric universe'
}
install_ubuntu_stable() {
apt-get -y install salt-minion
}
Since there is no ``install_ubuntu_1110_stable()`` it defaults to the
unspecified version script.
The bootstrapping script must be plain POSIX sh only, **not** bash or another
shell script. By design the targeting for each operating system and version is
very specific. Assumptions of supported versions or variants should not be
made, to avoid failed or broken installations.
Supported Operating Systems
---------------------------
- Ubuntu 10.x/11.x/12.x
- Debian 6.x
- CentOS 6.3
- Fedora
- Arch
- FreeBSD 9.0
One Line Bootstrap
------------------
Salt can be installed using a single line command.
For example, using ``curl`` to install latest git::
curl -L http://bootstrap.saltstack.org | sudo sh -s git develop
Or, using ``wget`` to install current distro's stable version::
wget -O - http://bootstrap.saltstack.org | sudo sh
If you have certificate issues using ``wget`` try the following::
wget --no-check-certificate -O - http://bootstrap.saltstack.org | sudo sh
