apcera-stager-api

Simple gem to assist users writing stagers for the Apcera Platform.

Usage

First create your Gemfile. The contents should be:

source "https://rubygems.org"

gem "apcera-stager-api"

Then run bundle install to download and install the gem and its dependencies.

Now that your environment is setup, create a new file for your stager. We recommend "stager.rb".

Start off with the contents:

#!/usr/bin/env ruby

require "bundler"
Bundler.setup

require "apcera-stager-api"

stager = Apcera::Stager.new

# Download the package from the staging coordinator.
# This is the code that requires staging!
puts "Downloading Package..."
stager.download

# Extract the package to the "app" directory.
puts "Extracting Package..."
stager.extract("app")

# Your custom staging logic goes here.
# This will be a set of commands to execute in order to stage
# your applications.

# Finish staging, this will upload your final package to the
# staging coordinator.
puts "Completed Staging..."
stager.complete

Deploying

Deploying just requires you to run apc stager create.

apc stager create mystager --start-command="./stager.rb" --staging=/apcera::ruby --pipeline

Now you can deploy apps using your stager with apc app create.

apc app create someapp --staging=mystager --start
