Pulumi's Python SDK

Project description

Slack NPM version Python version GoDoc License

Pulumi’s Cloud Native SDK is the easiest way to create and deploy cloud programs that use containers, serverless functions, hosted services, and infrastructure, on any cloud.

Simply write code in your favorite language and Pulumi automatically provisions and manages your AWS, Azure, Google Cloud Platform, and/or Kubernetes resources, using an infrastructure-as-code approach. Skip the YAML, and use standard language features like loops, functions, classes, and package management that you already know and love.

For example, create three web servers:

let aws = require("@pulumi/aws");
let sg = new aws.ec2.SecurityGroup("web-sg", {
    ingress: [{ protocol: "tcp", fromPort: 80, toPort: 80, cidrBlocks: ["0.0.0.0/0"]}],
});
for (let i = 0; i < 3; i++) {
    new aws.ec2.Instance(`web-${i}`, {
        ami: "ami-7172b611",
        instanceType: "t2.micro",
        securityGroups: [ sg.name ],
        userData: `#!/bin/bash
            echo "Hello, World!" > index.html
            nohup python -m SimpleHTTPServer 80 &`,
    });
}

Or a simple serverless timer that archives Hacker News every day at 8:30AM:

let cloud = require("@pulumi/cloud");
let snapshots = new cloud.Table("snapshots");
cloud.timer.daily("daily-yc-snapshot", { hourUTC: 8, minuteUTC: 30 }, () => {
    let req = require("https").get("https://news.ycombinator.com", (res) => {
        let content = "";
        res.setEncoding("utf8");
        res.on("data", (chunk) => { content += chunk });
        res.on("end", () => {
           snapshots.insert({ date: Date.now(), content: content });
        });
    });
    req.end();
});

Many examples are available spanning containers, serverless, and infrastructure in pulumi/examples.

Pulumi is open source under the Apache 2.0 license, supports many languages and clouds, and is easy to extend. This repo contains the pulumi CLI, language SDKs, and core Pulumi engine, and individual libraries are in their own repos.

Getting Started

Follow these steps to deploy your first Pulumi program, using AWS Serverless Lambdas, in minutes:

  1. Install:

    To install the latest Pulumi release, run the following (see full installation instructions for additional installation options):

    $ curl -fsSL https://get.pulumi.com/ | sh
    
  2. `Configure your Cloud Provider <https://pulumi.io/install#cloud-configuration>`__ so that Pulumi can deploy into it.

  3. Create a Project:

    After installing, you can get started with the pulumi new command:

    $ pulumi new hello-aws-javascript
    

    The new command offers templates for all languages and clouds. Run it without an argument and it’ll prompt you with available projects. This command created an AWS Serverless Lambda project written in JavaScript.

  4. Deploy to the Cloud:

    Run pulumi update to get your code to the cloud:

    $ pulumi update
    

    This makes all cloud resources needed to run your code. Simply make edits to your project, and subsequent pulumi updates will compute the minimal diff to deploy your changes.

  5. Use Your Program:

    Now that your code is deployed, you can interact with it. In the above example, we can curl the endpoint:

    $ curl $(pulumi stack output url)
    
  6. Access the Logs:

    If you’re using containers or functions, Pulumi’s unified logging command will show all of your logs:

    $ pulumi logs -f
    
  7. Destroy your Resources:

    After you’re done, you can remove all resources created by your program:

    $ pulumi destroy -y
    

Please head on over to the project website for much more information, including tutorials, examples, and an interactive tour of the core Pulumi CLI and programming model concepts.

Development

If you’d like to contribute to Pulumi and/or build from source, this section is for you.

Prerequisites

Pulumi is written in Go, uses Dep for dependency management, and GoMetaLinter for linting:

Building and Testing

To install the pre-built SDK, please run curl -fsSL https://get.pulumi.com/ | sh, or see detailed installation instructions on the project page. Read on if you want to install from source.

To build a complete Pulumi SDK, ensure $GOPATH is set, and clone into a standard Go workspace:

$ git clone git@github.com:pulumi/pulumi $GOPATH/src/github.com/pulumi/pulumi
$ cd $GOPATH/src/github.com/pulumi/pulumi

The first time you build, you must make ensure to install dependencies and perform other machine setup:

$ make ensure

In the future, you can synch dependencies simply by running dep ensure explicitly:

$ dep ensure

At this point you can run make to build and run tests:

$ make

This installs the pulumi binary into $GOPATH/bin, which may now be run provided make exited successfully.

The Makefile also supports just running tests (make test_all or make test_fast), just running the linter (make lint), just running Govet (make vet), and so on. Please just refer to the Makefile for the full list of targets.

Debugging

The Pulumi tools have extensive logging built in. In fact, we encourage liberal logging in new code, and adding new logging when debugging problems. This helps to ensure future debugging endeavors benefit from your sleuthing.

All logging is done using Google’s Glog library. It is relatively bare-bones, and adds basic leveled logging, stack dumping, and other capabilities beyond what Go’s built-in logging routines offer.

The pulumi command line has two flags that control this logging and that can come in handy when debugging problems. The --logtostderr flag spews directly to stderr, rather than the default of logging to files in your temp directory. And the --verbose=n flag (-v=n for short) sets the logging level to n. Anything greater than 3 is reserved for debug-level logging, greater than 5 is going to be quite verbose, and anything beyond 7 is extremely noisy.

For example, the command

$ pulumi preview --logtostderr -v=5

is a pretty standard starting point during debugging that will show a fairly comprehensive trace log of a compilation.
