Serverless Confirm Command

serverless npm package License

This Serverless Framework plugin allows you to define commands (as well as provider-specific options) that will require confirmation before being executed.

Features

  • Works with all cloud providers (and all runtimes)
  • Supports all CLI commands
  • Supports AWS stages and command/stage pairs

You can find a list of all serverless infrastructure providers (as well as their associated documentation) here.

Changelog

You can find the changelog here or in the releases section.

Disclaimer

One of the intentions of this plugin is to make it more difficult to accidentally deploy or remove a serverless application when it should not. Although it provides another layer of protection, it does not replace deployment and security policies for your applications. Please do not forget to set up and protect your deployments appropriately (especially your production environment).

Documentation

Prerequistes

  • Serverless Framework 1.0.0 or more recent
  • Node.js 6.4.0 or more recent

Installation

Install the plugin by running:

npm install serverless-confirm-command --save-dev

Alternatively, if you are using Yarn:

yarn add serverless-confirm-command --dev

Then add the plugin to your serverless.yml file plugin section:

plugins:
  - serverless-confirm-command

Configuration

You must configure the plugin in the custom section of your serverless.yml file, in a dedicated confirm section. All options (provider-agnostic or not) can be used at the same time.

Commands (provider-agnostic)

List the commands you want to confirm in a sub-section of the same name.

custom:
  confirm:
    commands:
      - 'deploy'
      - 'remove'

For instance, the configuration above will require both the deploy and remove commands to be confirmed.

List of commands

Please refer to the CLI reference of each provider for a complete list of available commands.

Additionally, it is important to note that each command possessing its own section in the documentation is considered a separate command. For instance, if you are using AWS as your cloud provider, deploy and deploy function are considered to be two different commands.

AWS options

In you are using AWS as your cloud provider, you can set up any stage and/or command/stage pair to require confirmation.

custom:
  confirm:
    aws:
      stages:
        - 'release'
      commandsForStages: # Must be listed as 'command:stage'
        - 'remove:prod'

For instance, the configuration above will require the following cases to be confirmed:

  • Any command using the stage release
  • The remove command used in combination with the prod stage

You can list as many stages and command/stage pairs as you want (as long as the command is supported by the plugin).

Usage

Once you have configured the plugin, you can continue to use the Serverless Framework exactly as you were before. The commands (and potentially the other options) you have configured will now need to be confirmed.

To confirm a command (or any option), you must provide the CLI option --confirm when using Serverless.

Example

Let us assume you want to configure the remove command to require confirmation to prevent accidental deletion of your application.

Configuration of the plugin:

custom:
  confirm:
    commands:
      - 'remove'

Using the command serverless remove will produce an error:

  Serverless Error ---------------------------------------

  Command not confirmed. Use [--confirm] or change the configuration of the plugin.

Using the command serverless remove --confirm will suceed!
