Lola

Lola is an opiniated cli tool to orchestrate AWS Cloudformation templates.

Installation

  $ [sudo] npm install lola -g

Usage

lola.yml

Lola expects a config file (lola.yml) which holds information about the AWS Cloudformation stacks you wish to control.

# The name of your project. This is required and will be used in
# stack names, tags, etc.
project: <project-name>

# List of key-value tags that should be added to each stack. When set on this or a lower level,
# it wil override the default tags of project, environment and region.
tags:
  <name-of-tag>: <value-of-tag>
  <name-of-another-tag>: <value-of-another-tag>

# Stacks is a description of the different cloudformation stacks you'll want to
# manage and the specific order in which they'll need to be managed.
stacks:
    # Give that stack a name.
    <stack1>:
        template: <location of the template.yml file for this stack>
        description: <optionally describe this stack>
        actions:
            preDeploy: preDeployScript.js

environments:
    # This is reserved, you can set global stuff for each stack in each env. Optional.
    default:
        <stack1>:
            # This will override ANY region/profile for stack1 in ANY env below
            region: <aws region>
            profile: <~/.aws/credentails profile name>
            tags:
              <name-of-tag>: <value-of-tag>
              <name-of-another-tag>: <value-of-another-tag>
    # Give that environment a name.
    <dev>:
        # Environment params for <stack1>
        <stack1>:
            # Override the stackname for this env. Optional, if not present lola generates one.
            name: <my-stack-dev>
            region: <aws region>
            profile: <~/.aws/credentails profile name>
            tags:
              <name-of-tag>: <value-of-tag>
              <name-of-another-tag>: <value-of-another-tag>
            terminationProtection: <true|false>
            params:
                <Param1>: <Value1>
            hooks:
                pre-deploy:
                    - preDeploy

Running lola

When running a lola command (validate, status, ..) without arguments, lola will ask about two things: the stack and the environment. These can also be provided through an input file (-o flag) or other input flags.

deploy hooks

• pre-deploy

actions

Each stack can define actions. Each action can be run on it's own or can be attached to one of the deploy hooks.

Since version 2.0.0, you can use traditional Common.js Modules or new ES Modules.

Common.js Modules
In package.json set "type": "commonjs" or leave it empty or name file with .cjs extension, not .js.

const { S3Client, PutObjectCommand } = require("@aws-sdk/client-s3");

/**
 * @param Object context
 */
async function runAction(context) {
    const { region } = context.config.environments[context.env][context.stackName];
    const { profile } = context.config.environments[context.env][context.stackName];
    const { params } = context.config.environments[context.env][context.stackName];

    throw new Error('Error');
}

module.exports.runAction = runAction;

ES Modules
In package.json set "type": "module" or name file with .mjs extension, not .js.

import { S3Client, PutObjectCommand } from "@aws-sdk/client-s3";
/**
 * @param Object context
 */
export async function runAction(context) {
    const { region } = context.config.environments[context.env][context.stackName];
    const { profile } = context.config.environments[context.env][context.stackName];
    const { params } = context.config.environments[context.env][context.stackName];

    throw new Error('Error');
}
