3: # Introduction
4:
5: This tutorial aims at showing how you can build, setup, upload and launch NetBSD under the [Amazon EC2](http://aws.amazon.com/ec2/) service. We will first give some brief explanations on how you can obtain an AWS account, and what you will need to run NetBSD under EC2. Then, at your convenience, you will be able to start with pre-made images, or roll-out your own.
6:
7: # Subscribe to AWS (Amazon Web Services)
8:
9: If you already have an account for [Amazon Web Services](http://aws.amazon.com/), and you are a registered user for EC2 service, you can directly jump to section [What do you need to know](#index2h2). If not, keep reading.
10:
11: ## Quick overview
12:
13: Before you can start playing with Amazon EC2, you have to create an account on Amazon Web Services, of which EC2, the Elastic Compute Cloud, is part. This is fairly straightforward, and done in two steps:
14:
15: 1. you "sign-up" directly on [Amazon Web Services](http://aws.amazon.com/) home-page. This is where you enter your credentials, and confirm your AWS account registration.
16: 1. you sign-up to EC2 through [EC2 AWS home-page](http://aws.amazon.com/ec2/). You will be asked some more information, like a credit card (for billing), and a phone-number, for account validation.
17:
18: ## What do you need to know?
19:
20: EC2 uses different types of credentials. In addition to your login and password, you need an access key, a X.509 certificate (with its private key), and a pair of RSA keys, for remote SSH access.
21:
22: These can be created through the [Security Credentials](https://aws-portal.amazon.com/gp/aws/developer/account/index.html?ie=UTF8&action=access-key) page (also accessible from the [Account](http://aws.amazon.com/account/) page):
23:
24: 1. create the access key. Keep a secured copy of the ID and its associated secret value. These will be used by various scripts later on to perform certain EC2 actions.
25: 1. note down your account number (different from your access key ID!). This identifier can usually be obtained in the right top part of the page; it is a serie of numbers, separated with dashes: XXXX-XXXX-XXXX.
26: 1. create, or upload, a X.509 certificate, in PEM format. Keep the private key in a safe place.
27: 1. lastly, generate Amazon EC2 key pairs that will be used for SSH access. This step will be performed through the [Amazon Management Console](https://console.aws.amazon.com/ec2/home). Note down the SSH Key Pair Name you chose.
28:
29: ### Keep your credentials!
30:
31: The different credentials created above will be used in various places of EC2, and by a myriad of commands. You are advised to keep them easily accessible, while still reasonably secure regarding their access. Most EC2 tools expect them to be find through a set of environment variables.
32:
33: For convenience, you could store them under a *.ec2* directory inside your *$HOME*:
34:
35: [[!template id=programlisting text="""
36: $ ls .ec2/
37: cert-SOMERANDOMKEY.pem # the X.509 certificate
38: id_rsa.ec2 # private RSA SSH key
39: id_rsa.ec2.pub # public RSA SSH key
40: pk-SOMERANDOMKEY.pem # the private key associated to the certificate
41: """]]
42:
43: then set the environment accordingly:
44:
45: [[!template id=programlisting text="""
46: export EC2_PRIVATE_KEY=$HOME/.ec2/pk-SOMERANDOMKEY.pem
47: export EC2_CERT=$HOME/.ec2/cert-SOMERANDOMKEY.pem
48: export EC2_SSH_KEY=$HOME/.ec2/id_rsa.ec2
49: export EC2_SSH_KEYNAME=<your_ssh_key_pair_name>
50: export EC2_ACCOUNT_NUM=XXXX-XXXX-XXXX
51: export EC2_ACCESS_KEY=MYACCESSKEYID
52: export EC2_SECRET_KEY=MYSECRETACCESSKEY
53: """]]
54:
55: Please note that the rest of the tutorial will assume that these variables are set.
56:
57: ## Installing EC2 API tools
58:
59: NetBSD provides EC2 API tools, to ease EC2 account management a little bit. The package is found inside [pkgsrc](http://www.pkgsrc.org), under [[!template id=pkg category=misc name=ec2-api-tools]].
60:
61: [[!template id=programlisting text="""
62: cd /usr/pkgsrc/misc/ec2-api-tools
63: make ACCEPTABLE_LICENSES+=amazon-software-license install
64: """]]
65:
66: Package depends on Java, so build will take some time to finish. While it builds, just continue reading.
67:
68: ## EC2 vocabulary -- last notes
69:
70: Before starting to play with EC2, you need to be familiar with the EC2 vocabulary used throughout this tutorial.
71:
72: Briefly said, EC2 uses [Xen](http://www.xen.org) as virtualization solution. So, in essence, all operating systems that support Xen para-virtualization can theoretically run inside EC2, as a domU. This is the case for NetBSD; however, please note that only amd64 is currently supported. Work is on-going to support 32 bits for EC2.
73:
74: All operating systems are run as *instances*, which are, as their name implies, the instantiation of a specific AMI, or *Amazon Machine Image*. An AMI is an image built from specific *snapshots* of *volumes*. The volumes are part of [Elastic Block Storage](http://aws.amazon.com/ebs/) (or EBS for short), which is another service offered by AWS, distinct from EC2.
75:
76: These instances are tied to a *region* (a geographical location; typically US East, US West, Europe West, etc.). Each region has *availability zones*, which can be compared to a sub-region, each one being physically distinct from another. Regions are identified by a name, like *us-east-1*, *eu-west-1*. Same goes for availability zones, usually with the region's name as prefix: *us-east-1a*, *us-east-1b*, and so forth. Note that resources are **not** shared between zones, so if you transfer data from one zone to another, you will be charged for it.
77:
78: AKI, or *Amazon Kernel Image*, are a specific type of image. It represents the Xen guest para-virtualized kernel, as used by an AMI. Certain AKIs are allowed to boot customized operating systems, e.g. those that are still not officially supported by Amazon. Thanks to [PyGrub](http://wiki.xensource.com/xenwiki/PyGrub), it can boot a kernel that resides inside an AMI's snapshot.
79:
80: # Using pre-made AMIs
81:
82: The following AMIs are publicly available. You can use them to [start a NetBSD instance](#index11h2) quickly, without needing to build your image by hand.

133:
134: ## Fetch and build NetBSD
135:
136: EC2 does not provide direct access to console. As a consequence, we cannot rely on it for installation, especially via [[!template id=man name=sysinst section=8]]. We must therefore build and install NetBSD in a separate directory, and configure it manually, before upload.
137:
138: This tutorial assumes that you will build the system under */mnt/ec2*.
139:
140: /!\Please note that you will need the [[!template id=man name=makefs section=8]] tool later in the process, so you can build a file system image that can be uploaded to Amazon EC2. You are therefore advised to perform the installation directly under a living NetBSD system, or in case your are not, to fetch the *src* tree to build the toolchain, which will contain the **nbmakefs** utility.
141:
142: [Details regarding on how you can fetch *src* are given in the NetBSD's guide](http://www.netbsd.org/docs/guide/en/chap-fetch.html). Here are the basic commands you should type to build and install NetBSD under */mnt/ec2*:
143:
144: [[!template id=programlisting text="""
145: cd /usr/
146: # grab a recent src.tgz file (use curl(1), ftp(1), wget(1), ...)
147: ftp -a 'http://ftp.netbsd.org/pub/NetBSD/NetBSD-current/tar_files/src.tar.gz'
148: # Decompress
149: tar -xzpf src.tar.gz
150: cd src
151: # build distribution and kernel

158: # Configuration of your NetBSD EC2 tree
159:
160: /!\This part assumes that you have a non-configured NetBSD system extracted under */mnt/ec2*; that is, it should have not been modified through [[!template id=man name=sysinst section=8]], nor by you.

269: # Upload NetBSD to EC2
270:
271: We must now upload our NetBSD system to EC2. For that, we will have to create a minimalist EC2 instance, to which we will copy our files to construct our snapshots. We will use an Amazon Linux AMI instance.
272:
273: EC2 being localized in geographical regions, you have to carefully choose the AMI identifier you want to use there. This depends on where you want to execute your instance. Amazon Linux AMI IDs are listed on [the main page](http://aws.amazon.com/amazon-linux-ami/) of the project, by regions. Choose ones backed by EBS.
274:
275: The examples listed here assume that the instances run in **US East**, within the **c** zone (e.g. **us-east-1c**). To have a list of EC2 regions, you can use the command **ec2-describe-regions**, and **ec2-describe-availability-zones** for availability zones.
276:
277: ## Create an Amazon Linux instance
278:
279: Creating an instance is straightforward. Amazon provides [different types of instances](http://aws.amazon.com/ec2/pricing/), with varying levels of billing and reliability. We will use a [*micro* instance](http://aws.amazon.com/ec2/faqs/#How_much_compute_power_do_Micro_instances_provide); its pricing is almost free.

392: ## Create your first NetBSD AMI
393:
394: An AMI requires multiples components to be registered: the snapshots IDs we made in the previous chapter, as well as a specific AKI: the one that can chain-load Xenified kernels through PyGrub.
395:
396: /!\ AKIs are entitled to the same conditions as AMIs: their IDs are region-specific. So choose one carefully, or you will not be able to launch your NetBSD instance later!
397:
398: The list of AKIs that suits our situation can be obtained with the following command:
399:

409: Pick the one with the correct architecture (x86_64 here). **hd0** are for AMIs where the snapshot contains no partition (where the volume is itself the whole partition), while **hd00** are for snapshots partitioned in a classical way (via MBR).

469: Done!
470:
471: ## And now?
472:
473: Well, you got a NetBSD instance that is in almost every part similar to what a NetBSD domU can be. You can use this domU to host Internet services, run a database, extend your build farm, or use it as a sandbox. The AMI being built around snapshots, you can play and break your instance in every way you want; just restart one anew if you need to. Don't forget that Amazon will charge acccordingly :)
474:
475: Remember, you can query information regarding your AWS account through [[!template id=pkg category=misc name=ec2-api-tools]] package. It is quite easy to use these tools for scripting; for a more elaborate, graphical interface, use the [Amazon Management Console](https://console.aws.amazon.com/ec2/home).
