Adapted bootstrapping script

bootstrap_salt_master_from_formula_aws.sh

#!/bin/sh

# Bootstaps a SaltStack master server
# salt-formula configures the salt master using salt itself. This includes establishing connections allowing salt to serve assets from git and s3 endpoints.
# Before this can happen, we need to perform a lightweight saltstack installation, clone salt-formula, and call a salt highstate.

# Note: The state and pillar for this formula stay in the repo from the formula and are copied into /srv/salt and /srv/pillar upon invocation of this script.
# This repo will be the source of truth for our state and pillar tops, even though we will recieve configuration via gitfs.

# Instructions
# 1) Ensure the root user has an ssh key. If not, create one with:
#   $ ssh-keygen -t rsa;
# 2) Add the root user's ssh public key to the salt-formula repo's list of access keys.
# 3) Navigate to /srv/salt. Clone the salt-formula repo with:
#   $ git clone git@bitbucket.org:opentempo/salt-formula.git . ; The . at the end is important so that we clone without the top level directory.
# 4) Run:
#   $ /srv/salt/salt-formula/setup/bootstrap_salt_master_from_formula_aws.sh;

# Script self-awareness variables
_script_path=$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd );
_script_filename=$(basename "${0}")

# Salt formula repo URL
_salt_formula_remote_url="git@bitbucket.org:opentempo/salt-formula.git"

# Salt statetree path
_salt_statetree_path="/srv/salt"

# Salt pillar path
_salt_pillar_path="/srv/pillar"

# Use the latest stable Salt from repo.saltstack.com
# Instructions from http://repo.saltstack.com/#amzn
sudo yum install https://repo.saltstack.com/yum/amazon/salt-amzn-repo-latest-2.amzn1.noarch.rpm

sudo yum clean expire-cache

sudo yum update -y

# Install the salt master and minion
sudo yum install salt-master -y

sudo yum install salt-minion -y

# Create the pillar directory
if [ ! -d "${_salt_pillar_path}" ]; then
  sudo mkdir -p "${_salt_pillar_path}"
fi

# Copy salt-formula pillar and top file to /srv/pillar
sudo cp "${_salt_statetree_path}/setup/pillar/salt.sls" "${_salt_pillar_path}/"
sudo cp "${_salt_statetree_path}/setup/pillar/top.sls" "${_salt_pillar_path}/"

# Copy salt-formula state top to /srv/salt
sudo cp "${_salt_statetree_path}/setup/salt/top.sls" "${_salt_statetree_path}/"

# Accept all keys
sleep 15 #give the minion a few seconds to register
sudo salt-key -y -A

# By this point we should be in a state where we can call salt-call state.highstate to trigger configuration
