Universal, serverless, single-command deployment

How it works

Now enables instant immutable deployments to any cloud provider with a simple API that's scalable, intuitive and optimized for collaboration.

This is all it takes to deploy, for example, a Node.js project:

cd my-project
cat server.js

require('http').createServer((req, res) => {
  res.end('▲ Hello World')
}).listen(process.env.PORT)

and deploy!

now

The output of the now command will be a unique url to the deployment. No need for git.

Features

• Single command deployment: now.
• 100% OSS and licensed under Apache 2.0
• Serverless. Worry about code, not servers.
• Immutable. Every time you write now, a new deployment is provisioned.
• Pluggable. Client can query any public and private cloud provider APIs
• Flexible. Interact with multiple clouds at once: now gcp deploy && now aws deploy
• Single command setup: now [provider] login
• Secure. All deployments are served over SSL
• Dynamic and Static. Deploy popular runtimes or static websites
• Remote fs support. Deploy any github project with now project/repo, gitlab with gitlab://. PRs welcome!

Installation

To install the latest version:

npm install -g now@beta

Note: while the API has been in production for over a year, the different providers are still under heavy development

Optionally, you can clone this repo and run npm run build to produce the pkg binaries.

Setup

Configuration of one or more providers via login command is necessary. If no logins are active and now

Global configuration is stored as ~/.now/config.json. Your default provider will be the first one you log in to.

Now.sh

now login

To skip the configuration steps and deploy to https://now.sh execute now login without any parameters, defaulting to the sh provider (equivalent to: now sh login).

Now.sh is free for open-source projects and static deployments. It supports Dockerfile, package.json and static sites out of the box. All builds are reproducible and executed in the cloud.

AWS Lambda (aws)

Run:

now aws login

If you have already run aws configure before, you will be offered to synchronize your credentials.

Serverless deployments are provisioned by using:

• Lambda functions λ
  • A proxy is automatically used to bridge the API between HTTP and lambda functions and retain a consistent interface
• Certificate Manager
• API Gateway

Google Cloud Platform (gcp)

$ now gcp login

and follow the instructions!

Microsoft Azure (az)

$ now az login

and follow the instructions!

Project Configuration

ℹ️	We welcome feedback from the community!

The v1 release of now.json includes the following specification:

• name (optional, recommended) String
• description (optional, recommended) String
• type (optional, recommended). One of:
  • String an unique identifier for the project type. The following are recommended choices to be supported by every provider:
    • docker
    • nodejs
    • static
  • Object when it's necessary to specify a version or multiple interacting runtimes. It's a dictionary of runtime identifier and SemVer-compatible version. For example:

    { "type": { "docker": "1.x.x" } }
    

  • provider (optional) indicates affinity to a certain provider
• target (optional) String
  • specifies a directory or file to deploy. If relative, it's resolved to the project directory. This is useful when a certain deployment type (like static) has an output target, like an out or dist directory.
• env (optional). One of
  • Object a dictionary mapping the name of the environmental variable to expose to the deployment and its value. If the value begins with @, it's considered a
  • Array a list of suggested environmental variables that the project might require to be deployed and function correctly
• regions - Array of String
  • specifies one or more regition identifiers to deploy to. A wildcard can be used to signify deployment to all supported regions by the provider
• files - Array of String
  • specifies a whitelist of what files have to be deployed

To supply provider-specific configuration, you can include an arbitrary Object and use the provider identifier as the key.

Global Configuration

The client will initialize a .now directory in the user's home directory upon first running.

There, two files can be found:

• config.json
• credentials.json

Implementation notes

Now is directly modeled after UNIX. It's useful to think of the primary subcommands deploy, alias and rm as being the "cloud equivalents" of cp, ln and rm.

The minimal set of commands that providers must supply are:

[] / deploy	the default command to launch a deployment
remove / rm	remove a deployment identified by its unique URL

Recommended, but not required, commands are:

logs | ln	associates a URL with a permanent domain name
secrets ls rm add	associates a URL with a permanent domain name
domains ls / add / rm	manage domains
dns ls / add / rm	manage dns records
certs ls / add / rm	manage certificates

The build step for serverless deployments is implemented locally and is compatible with projects configured with the type nodejs, and others are on the way!

Philosophy

Immutability

Each time you write now a new deployment is provisioned. Whenever possible, providers should strive to make deployments idempotent in the absence of changes to:

• Originating source code
• Configuration
• Environment variables

Standards compliance

All projects expose a HTTP/1.1-compatible interface. A port is provided via the standard process.env.PORT.

Secure

Whenever possible, deployments are strongly encouraged to be served over SSL. The process of provisioning certificates should be transparent to the user.

Projects should require minimal JSON configuration

Whenever possible, projects should be deployable with minimal or no configuration.

Avoid manifest duplication

If the configuration or conventions imposed by a programming language or framework are present, attempt to provide sane defaults.

Examples of this is the presence of Dockerfile or package.json. When publishing a project it's recommended that the type is strictly configured in now.json to avoid

Ongoing development

• Support for now <file>, with support for:
  • Binaries as a first-class deployment type
  • Static deployments as a fallback
• We are working on built-in support for provisioning Kubernetes replication controllers and pods, in a similar vein as the Draft project.
• A simple API to register custom providers and pluggable build systems externally, such as Travis, Circle CI, etc.
• A companion desktop app Now Desktop is available, released under the MIT license. Work is ongoing for pluggable providers to enable:
  • Team collaboration
  • One-click context switch
  • Drag and drop deployments
• Adding interoperabity between objects that live in different providers
• Providing a Next.js and React powered dashboard that can be deployed anywhere
