greenlock-store-sequelize | A Root project

A database-driven Greenlock storage plugin with wildcard support.

Features

• Many Supported SQL Databases
  • PostgreSQL (best)
  • SQLite3 (easiest)
  • Microsoft SQL Server (mssql)
  • MySQL, MariaDB
• Works on all platforms
  • Mac, Linux, VPS
  • AWS, Heroku, Akkeris, Docker
  • Windows

Usage

To use, provide this Greenlock storage plugin as the store option when you invoke create:

Greenlock.create({
  store: require('greenlock-store-sequelize')
  ...
});

Configuration

• SQLite3 (default)
• Database URLs / Connection Strings
• Environment variables
• Table Prefixes

SQLite3 (default)

SQLite3 is the default database, however, since it has a large number of dependencies and may require a native module to be built, you must explicitly install sqlite3:

npm install --save sqlite3

The default db file will be written wherever Greenlock's configDir is set to, which is probably ~/acme or ~/letsencrypt.

~/acme/db.sqlite3

If you wish to set special options you may do so by passing a pre-configured Sequelize instance:

var Sequelize = require('sequelize');
var db = new Sequelize({ dialect: 'sqlite', storage: '/Users/me/acme/db.sqlite3' });

Greenlock.create({
  store: require('greenlock-store-sequelize').create({ db: db })
  ...
});

Database URL Connection String

You may use database URLs (also known as 'connection strings') to initialize sequelize:

var Sequelize = require('sequelize');
var db = new Sequelize('postgres://user:pass@hostname:port/database');

Greenlock.create({
  store: require('greenlock-store-sequelize').create({ db: db })
  ...
});

If you need to use custom options, just instantiate sequelize directly:

var dbUrl = 'postgres://user:pass@hostname:port/database';

Greenlock.create({
  store: require('greenlock-store-sequelize').create({ storeDatabaseUrl: dbUrl })
  ...
});

For more information, see the Sequelize Getting Started docs.

ENVs (i.e. for Docker, Heroku, Akkeris)

If your database connection string is in an environment variable, you would use the usual standard for your platform.

For example, if you're using Heroku, Akkeris, or Docker you're database connection string is probably DATABASE_URL, so you'd do something like this:

var Sequelize = require('sequelize');
var databaseUrl = process.env['DATABASE_URL'];
var db = new Sequelize(databaseUrl);

Greenlock.create({
  store: require('greenlock-store-sequelize').create({ db: db })
  ...
});

Table Prefixes

The default table names are as follows:

• Keypair
• Domain
• Certificate
• Chain

If you'd like to add a table name prefix or define a specific schema within the database (PostgreSQL, SQL Server), you can do so like this:

var Sequelize = require('sequelize');
var databaseUrl = process.env['DATABASE_URL'];
var db = new Sequelize(databaseUrl, {
    hooks: {
        beforeDefine: function (columns, model) {
          model.tableName = 'MyPrefix' + model.name.plural;
          //model.schema = 'public';
        }
    }
});

Greenlock.create({
  store: require('greenlock-store-sequelize').create({ db: db })
  ...
});

Table Structure

This is the table structure that's created.

CREATE TABLE `Keypairs` (
  `id` INTEGER PRIMARY KEY AUTOINCREMENT,
  `xid` VARCHAR(255) UNIQUE,
  `content` TEXT,
  `createdAt` DATETIME NOT NULL,
  `updatedAt` DATETIME NOT NULL);

CREATE TABLE `Domains` (
  `id` INTEGER PRIMARY KEY AUTOINCREMENT,
  `subject` VARCHAR(255) UNIQUE,
  `altnames` TEXT,
  `createdAt` DATETIME NOT NULL,
  `updatedAt` DATETIME NOT NULL);

CREATE TABLE `Certificates` (
  `id` INTEGER PRIMARY KEY AUTOINCREMENT,
  `subject` VARCHAR(255) UNIQUE,
  `cert` TEXT,
  `issuedAt` DATETIME,
  `expiresAt` DATETIME,
  `altnames` TEXT,
  `chain` TEXT,
  `createdAt` DATETIME NOT NULL,
  `updatedAt` DATETIME NOT NULL);

CREATE TABLE `Chains` (
  `id` INTEGER PRIMARY KEY AUTOINCREMENT,
  `xid` VARCHAR(255) UNIQUE,
  `content` TEXT,
  `createdAt` DATETIME NOT NULL,
  `updatedAt` DATETIME NOT NULL,
  `CertificateId` INTEGER REFERENCES
  `Certificates` (`id`) ON DELETE SET NULL ON UPDATE CASCADE);
