Fastify+Let's Encryptでhttpsサーバーを立てる
はじめに
そういえばFastifyでLet's Encryptを導入したことなかったのを思い出したので検証のためにやってみた。ついでにLet's Encryptの記事を書いてなかった気がするので証明書作成の方法も丁寧に書いておこうと思う。
環境
- AWS EC2 Ubuntu 20.04の適当なインスタンス
- セキュリティグループで HTTPS(443)を開けておく
- インスタンスにドメインを割り当てておく今回はテスト用に letsencrypttest.bathtimefish.com
をRoute53で割り当てた
Let's Encryptで証明書を発行する
まずは certbot
をインストールする
sudo apt update
sudo apt upgrade
sudo apt install -y certbot
対話形式でStandaloneな証明書を発行する
sudo certbot certonly --standalone
いろいろ聞かれる。メールアドレスを入力

Obtaining a new certificate
Performing the following challenges:
http-01 challenge for letsencrypttest.bathtimefish.com
Waiting for verification...
Cleaning up challenges
IMPORTANT NOTES:
- Congratulations! Your certificate and chain have been saved at:
/etc/letsencrypt/live/letsencrypttest.bathtimefish.com/fullchain.pem
Your key file has been saved at:
/etc/letsencrypt/live/letsencrypttest.bathtimefish.com/privkey.pem
Your cert will expire on 2021-07-03. To obtain a new or tweaked
version of this certificate in the future, simply run certbot
again. To non-interactively renew *all* of your certificates, run
"certbot renew"
- Your account credentials have been saved in your Certbot
configuration directory at /etc/letsencrypt. You should make a
secure backup of this folder now. This configuration directory will
also contain certificates and private keys obtained by Certbot so
making regular backups of this folder is ideal.
- If you like Certbot, please consider supporting our work by:
Donating to ISRG / Let's Encrypt: https://letsencrypt.org/donate

証明書は /etc/letsencrypt/live/[ドメイン名]
下に作成される
sudo ls /etc/letsencrypt/live/letsencrypttest.bathtimefish.com
README cert.pem chain.pem fullchain.pem privkey.pem
要はこいつをFastifyで読み込めば良い
httpsサーバーを作成する
node.jsをセットアップする
sudo apt install -y nodejs npm
sudo npm i -g n
sudo n latest
sudo npm i -S typescript ts-node
sudo apt remove nodejs
sudo apt autoclean
サーバー開発に必要なものをセットアップする
mkdir -p ./work && cd $_
npm i -S fastify
npm i -D @types/node
npx tsc --init
コードは以下
import * as fs from 'fs';
import * as http2 from 'http2';
import fastify from 'fastify';
const certPath = '/etc/letsencrypt/live/letsencrypttest.bathtimefish.com';
const server = fastify({
logger: true,
http2: true,
https: {
key: fs.readFileSync(`${certPath}/privkey.pem`),
cert: fs.readFileSync(`${certPath}/fullchain.pem`)
},
});
server.get('/', function (request, reply) {
reply.code(200).send({ hello: 'world' });
});
server.listen(443, '0.0.0.0', (err, address) => {
if (err) {
console.error(err);
process.exit(1);
}
});
実行する
証明書が/etc
下にあるのとポート443を使うのでsudo
付きで実行する。
sudo ts-node index.ts
ローカルでhttpsアクセスしてみる
curl https://letsencrypttest.bathtimefish.com/
{"hello":"world"}
うまくいった。
おわりに
expressと似たような感じでFastifyでも簡単にhttps化できる。Fastifyのノウハウってけっこう少ない気がするのでこういうtipsもちょっとずつ書いていったほうがいいかな。忘れるし。
