Bootstrapping Salt
==================

|build|

.. contents::
    :local:

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.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. For Windows, use the
``bootstrap-salt.ps1`` script.

**NOTE**

This ``README`` file is not the absolute truth as to what the bootstrap script is capable of. For
that, please read the generated help by passing ``-h`` to the script or even better,
`read the source`_.

Also, to secure your Salt installation, check out these instructions for `hardening salt`_.

Bootstrap
=========

In every two-step installation example, you would be well-served to **verify against the SHA256
sum** of the downloaded ``bootstrap-salt.sh`` file.

    - bootstrap-salt.sh git 06f249901a2e2f1ed310d58ea3921a129f214358

  Options:
    -h  Display this message
    -v  Display script version
    -n  No colours
    -D  Show debug output
    -c  Temporary configuration directory
    -g  Salt Git repository URL. Default: https://github.com/saltstack/salt.git
    -w  Install packages from downstream package repository rather than
        upstream, saltstack package repository. This is currently only
        implemented for SUSE.
    -k  Temporary directory holding the minion keys which will pre-seed
        the master.
    -s  Sleep time used when waiting for daemons to start, restart and when
        checking for the services running. Default: 3
    -L  Also install salt-cloud and required python-libcloud package
    -M  Also install salt-master
    -S  Also install salt-syndic
    -N  Do not install salt-minion
    -X  Do not start daemons after installation
    -d  Disables checking if Salt services are enabled to start on system boot.
        You can also do this by touching /tmp/disable_salt_checks on the target
        host. Default: ${BS_FALSE}
    -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 only works for functions which actually
        implement pip based installations.
    -U  If set, fully upgrade the system prior to bootstrapping Salt
    -I  If set, allow insecure connections while downloading any files. For
        example, pass '--no-check-certificate' to 'wget' or '--insecure' to
        'curl'. On Debian and Ubuntu, using this option with -U allows obtaining
        GnuPG archive keys insecurely if distro has changed release signatures.
    -F  Allow copied files to overwrite existing (config, init.d, etc)
    -K  If set, keep the temporary files in the temporary directories specified
        with -c and -k
    -C  Only run the configuration function. Implies -F (forced overwrite).
        To overwrite Master or Syndic configs, -M or -S, respectively, must
        also be specified. Salt installation will be ommitted, but some of the
        dependencies could be installed to write configuration with -j or -J.
    -A  Pass the salt-master DNS name or IP. This will be stored under
        ${BS_SALT_ETC_DIR}/minion.d/99-master-address.conf
    -i  Pass the salt-minion id. This will be stored under
        ${BS_SALT_ETC_DIR}/minion_id
    -p  Extra-package to install while installing Salt dependencies. One package
        per -p flag. You are responsible for providing the proper package name.
    -H  Use the specified HTTP proxy for all download URLs (including https://).
        For example: http://myproxy.example.com:3128
    -b  Assume that dependencies are already installed and software sources are
        set up. If git is selected, git tree is still checked out as dependency
        step.
    -f  Force shallow cloning for git installations.
        This may result in an "n/a" in the version number.
    -l  Disable ssl checks. When passed, switches "https" calls to "http" where
        possible.
    -V  Install Salt into virtualenv
        (only available for Ubuntu based distributions)
    -a  Pip install all Python pkg dependencies for Salt. Requires -V to install
        all pip pkgs into the virtualenv.
        (Only available for Ubuntu based distributions)
    -r  Disable all repository configuration performed by this script. This
        option assumes all necessary repository configuration is already present
        on the system.
    -R  Specify a custom repository URL. Assumes the custom repository URL
        points to a repository that mirrors Salt packages located at
        repo.saltproject.io. The option passed with -R replaces the
        "repo.saltproject.io". If -R is passed, -r is also set. Currently only
        works on CentOS/RHEL and Debian based distributions.
    -J  Replace the Master config file with data passed in as a JSON string. If
        a Master config file is found, a reasonable effort will be made to save
        the file with a ".bak" extension. If used in conjunction with -C or -F,
        no ".bak" file will be created as either of those options will force
        a complete overwrite of the file.
    -j  Replace the Minion config file with data passed in as a JSON string. If
        a Minion config file is found, a reasonable effort will be made to save
        the file with a ".bak" extension. If used in conjunction with -C or -F,
        no ".bak" file will be created as either of those options will force
        a complete overwrite of the file.
    -q  Quiet salt installation from git (setup.py install -q)
    -x  Changes the Python version used to install Salt.
        For CentOS 6 git installations python2.7 is supported.
        Fedora git installation, CentOS 7, Ubuntu 18.04 support python3.
    -y  Installs a different python version on host. Currently this has only been
        tested with CentOS 6 and is considered experimental. This will install the
        ius repo on the box if disable repo is false. This must be used in conjunction
        with -x <pythonversion>.  For example:
            sh bootstrap.sh -P -y -x python2.7 git v2017.7.2
        The above will install python27 and install the git version of salt using the
        python2.7 executable. This only works for git and pip installations.

The Salt Bootstrap script has a wide variety of options that can be passed as
well as several ways of obtaining the bootstrap script itself. Note that the use of ``sudo``
is not needed when running these commands as the ``root`` user.

**NOTE**

The examples below show how to bootstrap Salt directly from GitHub or another Git repository.
Run the script without any parameters to get latest stable Salt packages for your system from
`SaltStack's corporate repository`_. See first example in the `Install using wget`_ section.


Install using curl
~~~~~~~~~~~~~~~~~~

If you want to install a package of a specific release version, from the SaltStack repo:

.. code:: console

  curl -o bootstrap-salt.sh -L https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh -P stable 3004.1

If you want to install a specific release version, based on the Git tags:

.. code:: console

  curl -o bootstrap-salt.sh -L https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh git v3004.1

Using ``curl`` to install latest development version from GitHub:

.. code:: console

  curl -o bootstrap-salt.sh -L https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh git master

To install a specific branch from a Git fork:

.. code:: console

  curl -o bootstrap-salt.sh -L https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh -g https://github.com/myuser/salt.git git mybranch

If all you want is to install a ``salt-master`` using latest Git:

.. code:: console

  curl -o bootstrap-salt.sh -L https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh -M -N git master

If your host has Internet access only via HTTP proxy, from the SaltStack repo:

.. code:: console

  PROXY='http://user:password@myproxy.example.com:3128'
  curl -o bootstrap-salt.sh -L -x "$PROXY" https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh -P -H "$PROXY" stable

If your host has Internet access only via HTTP proxy, installing via Git:

.. code:: console

  PROXY='http://user:password@myproxy.example.com:3128'
  curl -o bootstrap-salt.sh -L -x "$PROXY" https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh -H "$PROXY" git


Install using wget
~~~~~~~~~~~~~~~~~~

Using ``wget`` to install your distribution's stable packages:

.. code:: console

  wget -O bootstrap-salt.sh https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh

Installing a specific version from git using ``wget``:

.. code:: console

  wget -O bootstrap-salt.sh https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh git v3004.1

Installing a specific version package from the SaltStack repo using ``wget``:

.. code:: console

  wget -O bootstrap-salt.sh https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh -P stable 3004.1

**NOTE**

On the above examples we added ``-P`` which will allow PIP packages to be installed if required.
However, the ``-P`` flag is not necessary for Git-based bootstraps.


Install using Python
~~~~~~~~~~~~~~~~~~~~

If you already have Python installed, ``python 2.7``, then it's as easy as:

.. code:: console

  python -m urllib "https://bootstrap.saltproject.io" > bootstrap-salt.sh
  sudo sh bootstrap-salt.sh -P stable 3004.1

With python version 2, the following in-line code should always work:

.. code:: console

  python -c 'import urllib; print urllib.urlopen("https://bootstrap.saltproject.io").read()' > bootstrap-salt.sh
  sudo sh bootstrap-salt.sh git master

With python version 3:

.. code:: console

  python3 -c 'import urllib.request; print(urllib.request.urlopen("https://bootstrap.saltproject.io").read().decode("ascii"))' > bootstrap-salt.sh
  sudo sh bootstrap-salt.sh git v3004.1

Install using fetch
~~~~~~~~~~~~~~~~~~~

On a FreeBSD-based system you usually don't have either of the above binaries available. You **do**
have ``fetch`` available though:

.. code:: console

  fetch -o bootstrap-salt.sh https://bootstrap.saltproject.io
  sudo sh bootstrap-salt.sh

If you have any SSL issues install ``ca_root_nss``:

.. code:: console

  pkg install ca_root_nss

And either copy the certificates to the place where fetch can find them:

.. code:: console

  cp /usr/local/share/certs/ca-root-nss.crt /etc/ssl/cert.pem

Or link them to the right place:

.. code:: console

  ln -s /usr/local/share/certs/ca-root-nss.crt /etc/ssl/cert.pem


Installing via an Insecure One-Liner
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The following examples illustrate how to install Salt via a one-liner.

**NOTE**

Warning! These methods do not involve a verification step and assume that the delivered file is
trustworthy.

Any of the examples above which use two lines can be made to run in a single-line
configuration with minor modifications.

Installing the latest stable release of Salt (default):

.. code:: console

  curl -L https://bootstrap.saltproject.io | sudo sh

Using ``wget`` to install your distribution's stable packages:

.. code:: console

  wget -O - https://bootstrap.saltproject.io | sudo sh

Installing a target version package of Salt from the SaltStack repo:

.. code:: console

  curl -L https://bootstrap.saltproject.io | sudo sh -s -- stable 3004.1

Installing the latest master branch of Salt from git:

.. code:: console

  curl -L https://bootstrap.saltproject.io | sudo sh -s -- git master


Install on Windows
~~~~~~~~~~~~~~~~~~

Using ``PowerShell`` to install latest stable version:

.. code:: powershell

  [System.Net.ServicePointManager]::SecurityProtocol = [System.Net.SecurityProtocolType]'Tls12'
  Invoke-WebRequest -Uri https://winbootstrap.saltproject.io -OutFile "$env:TEMP\bootstrap-salt.ps1"
  Set-ExecutionPolicy -ExecutionPolicy RemoteSigned -Scope CurrentUser
  & "$env:TEMP\bootstrap-salt.ps1"

Display information about the install script parameters:

.. code:: powershell

  Get-Help $env:TEMP\bootstrap-salt.ps1 -Detailed

Using ``cygwin`` to install latest stable version:

.. code:: console

  curl -o bootstrap-salt.ps1 -L https://winbootstrap.saltproject.io
  "/cygdrive/c/WINDOWS/System32/WindowsPowerShell/v1.0/powershell.exe" -NoProfile -InputFormat None -ExecutionPolicy Bypass -Command "[System.Net.ServicePointManager]::SecurityProtocol = 3072; iex ./bootstrap-salt.ps1"


Supported Operating Systems
---------------------------

The salt-bootstrap script officially supports the distributions outlined in
`Salt's Supported Operating Systems`_ document, except for Solaris and AIX. The operating systems
listed below should reflect this document but may become out of date. If an operating system is
listed below, but is not listed on the official supported operating systems document, the level of
support is "best-effort".

Since Salt is written in Python, the packages available from `SaltStack's corporate repository`_
are CPU architecture independent and could be installed on any hardware supported by Linux kernel.
However, SaltStack does package Salt's binary dependencies only for ``x86_64`` (``amd64``) and
``AArch32`` (``armhf``). The latter is available only for Debian/Raspbian 8 platforms.

It is recommended to use ``git`` bootstrap mode as described above to install Salt on other
architectures, such as ``x86`` (``i386``), ``AArch64`` (``arm64``) or ``ARM EABI`` (``armel``).
You also may need to disable repository configuration and allow ``pip`` installations by providing
``-r`` and ``-P`` options to the bootstrap script, i.e.:

.. code:: console

  sudo sh bootstrap-salt.sh -r -P git master

**NOTE**

Bootstrap may fail to install Salt on the cutting-edge version of distributions with frequent
release cycles such as: Amazon Linux, Fedora, openSUSE Tumbleweed, or Ubuntu non-LTS. Check the
versions from the list below. Also, see the `Unsupported Distro`_ section.

Ubuntu Best Effort Support: Non-LTS Releases
********************************************

This script provides best-effort support for current, non-LTS Ubuntu releases. If package
repositories are not provided on `SaltStack's Ubuntu repository`_ for the non-LTS release, the
bootstrap script will attempt to install the packages for the most closely related LTS Ubuntu
release instead.

For example, when installing Salt on Ubuntu 21.10, the bootstrap script will setup the repository
for Ubuntu 20.04 from `SaltStack's Ubuntu repository`_ and install the 20.04 packages.

Non-LTS Ubuntu releases are not supported once the release reaches End-of-Life as defined by
`Ubuntu's release schedule`_.

Using a custom salt bootstrap
-----------------------------

By default the ``salt-cloud -p`` provisioning command will use the latest release from this
repository to bootstrap new minions. If

- your needs are not met by that script,
- you want to lock salt bootstrap to a specific release, or
- you want to use an unreleased development version of this script

you can add your bootstrap-salt script to your salt cloud configuration and point to it with the
``script`` attribute.

Unsupported Distributions
-------------------------

If you are running a Linux distribution that is not supported yet or is not correctly identified,
please run the following commands and report their output when creating an issue:

.. code:: console

  sudo find /etc/ -name \*-release -print -exec cat {} \;
  command lsb_release -a

For information on how to add support for a currently unsupported distribution, please refer to the
`Contributing Guidelines`_.

Python 3 Support
----------------

Some distributions support installing Salt to use Python 3 instead of Python 2. The availability of
this offering, while limited, is as follows:

- CentOS 7
- Debian 10
- Debian 11
- Fedora (only git installations)
- Ubuntu 18.04
- Ubuntu 20.04

On Fedora, PIP installation must be allowed (-P) due to incompatibility with the shipped Tornado
library.

Installing the Python 3 packages for Salt is done via the ``-x`` option:

.. code:: console

    sh bootstrap-salt.sh -x python3

See the ``-x`` option for more information.

The earliest release of Salt that supports Python3 is `2018.3.4`.

Tornado 5/6 Workaround
----------------------
Salt does not support tornado>=5.0 currently. This support will be included in an upcoming release.
In order to work around this requirement on OSs that no longer have the tornado 4 package
available in their repositories we are pip installing tornado<5.0 in the bootstrap script. This
requires the user to pass -P to the bootstrap script if installing via git to ensure tornado is pip
installed.  If a user does not pass this argument they will be warned that it is required for the
tornado 5 workaround. So far the OSs that are using this workaround are Debian 10, Centos 8 and
Fedora 31.

Testing
-------

There are a couple of ways to test the bootstrap script. Running the script on a fully-fledged
VM is one way. Other options include using Vagrant or Docker.

Testing in Vagrant
==================

Vagrant_ can be used to easily test changes on a clean machine. The ``Vagrantfile`` defaults to an
Ubuntu box. First, install Vagrant, then:

.. code:: console

  vagrant up
  vagrant ssh

Running in Docker
=================

It is possible to run and use Salt inside a Docker_ container on Linux machines.
Let's prepare the Docker image using the provided ``Dockerfile`` to install both a Salt Master
and a Salt Minion with the bootstrap script:

.. code:: console

  docker build -t local/salt-bootstrap .

Start your new container with Salt services up and running:

.. code:: console

  docker run --detach --name salt --hostname salt local/salt-bootstrap

And finally "enter" the running container and make Salt fully operational:

.. code:: console

  docker exec -i -t salt /bin/bash
  salt-key -A -y

Salt is ready and working in the Docker container with the Minion authenticated on the Master.

**NOTE**

The ``Dockerfile`` here inherits the Ubuntu 14.04 public image with Upstart configured as the init
system. Use it as an example or starting point of how to make your own Docker images with suitable
Salt components, custom configurations, and even `pre-accepted Minion keys`_ already installed.

Updating Drone Pipelines
========================

You should install and configure the drone-cli as shown here: https://docs.drone.io/cli/install/

Make edits to .drone.jsonnet and then save them into the .drone.yml by doing the following:

.. code:: console

  drone jsonnet --format --stream
  drone sign saltstack/salt-bootstrap --save
