一、Vagrant
file: Vagrant
# -*- mode: ruby -*-
# vi: set ft=ruby :
# All Vagrant configuration is done below. The "2" in Vagrant.configure
# configures the configuration version (we support older styles for
# backwards compatibility). Please don‘t change it unless you know what
# you‘re doing.
Vagrant.configure("2") do |config|
# The most common configuration options are documented and commented below.
# For a complete reference, please see the online documentation at

# Every Vagrant development environment requires a box. You can search for
# boxes at https://vagrantcloud.com/search.
config.vm.box = "centos/7"
config.vm.hostname = "prometheus"
# Disable automatic box update checking. If you disable this, then

# config.vm.box_check_update = false
# Create a forwarded port mapping which allows access to a specific port
# within the machine from a port on the host machine. In the example below,
# accessing "localhost:8080" will access port 80 on the guest machine.
# NOTE: This will enable public access to the opened port
# config.vm.network "forwarded_port", guest: 80, host: 8080
# Create a forwarded port mapping which allows access to a specific port

# via 127.0.0.1 to disable public access
# config.vm.network "forwarded_port", guest: 80, host: 8080, host_ip: "127.0.0.1"
# Create a private network, which allows host-only access to the machine
# using a specific IP.
# config.vm.network "private_network", ip: "192.168.33.10"

# Share an additional folder to the guest VM. The first argument is

vb.gui = false
# Customize the amount of memory on the VM:
vb.memory = "4096"
vb.cpus = "4"
end
#
# View the documentation for the provider you are using for more
# information on available options.
# Enable provisioning with a shell script. Additional provisioners such as
# Ansible, Chef, Docker, Puppet and Salt are also available. Please see the
# documentation for more information about their specific syntax and use.

# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: ‘prometheus‘
# metrics_path defaults to ‘/metrics‘
# scheme defaults to ‘http‘.
