Saltstack install

General

Installation Type

Salt has very flexible installation options. Before you install, you should decide how you'd like to use salt.

• salt-master/salt-minion:
  • salt-master: hosted on central server. keeps the statefiles, pillar, and manages encryption/decryption of pillar.
  • salt-minion: hosted on each salt-managed server. Receives/Applies instructions from salt-master.
• serverless
  • states/pillar stored locally, and states are applied with argument --local.

Installer Options

If you are installing on a unix system, you can install salt either by using the version of salt in your distrobution's package repository or using salt's bootstrap script.

• unix: use your distrobution's installer if current enough for salt-master. Fall back on bootstrap script.
• windows: use chocolatey if installed, otherwise https://docs.saltstack.com/en/latest/topics/installation/windows.html

Bootstrap script Install

curl -L https://bootstrap.saltstack.com -o /tmp/install_salt.sh
sudo sh /tmp/install_salt.sh -M
rm      /tmp/install_salt.sh

platforms

Virtualenv

NOTE:

virtualenv could be used on it's own, but salt also has requirements on the python version that is used. It is safest to use pyenv to handle this requirement.

Saltstack is written in python, an interpreted language.
Most package managers do not isolate installed programs, leading to requirement conflicts.
There is value in installing saltstack into a virtualenv, so that your userland and saltstack do not conflict with each other.
Downsides include taking responsibility for updates. Please make certain to do so!

Base Install

NOTE:

Check classifiers to determine latest supported python version
https://github.com/saltstack/salt/blob/master/setup.py

NOTE:

It would be sensible to create a repo of pipenv managed services, then you could install the same one across multiple OS's

sudo -i
pacman -S python-pipenv         # use your dist's pkg manager
mkdir -p services/saltstack \
  && cd services/saltstack

cat <<EOF > servics/saltstack/Pipfile
[[source]]
url = "https://pypi.org/simple"
verify_ssl = true
name = "pypi"

[packages]
virtualenv = "*"

[dev-packages]

[requires]
python_version = "3.9"
EOF

pipenv install
pipenv run virtualenv venv
venv/bin/pip install salt

systemd

You'll also want to install symlinks for salt's various executables.

for exe in salt-api salt salt-api salt-call salt-cloud salt-cp salt-key salt-run salt-ssh salt-syncdic salt-unity; do
    (test -e /usr/bin/${exe} || test -L /usr/bin/${exe}) && sudo rm -rf /usr/bin/${exe}
    sudo ln -s /root/services/saltstack/venv/bin/${exe} /usr/bin/${exe}
done

Finally, enable

systemctl --system daemon-reload
systemctl enable virtualenv-salt-minion.service
