Running your Symfony project on AWS Lambda

Given during Symfony Live London 2018, this presentation showcases a new tool called Bref, which takes the pain out of deploying PHP projects on AWS Lambda, allowing you to focus on your application code while saving money by cutting down on wasted server resources.

18. Lambda is a piece of code that only costs you money while it’s being executed
19. Lambda & PHP from scratch is a PITA

29. • Well documented • Serverless framework plugin (easy to get running) • Built on top of FIG standards (PSR-7) mnapoli/bref
30. Lambda function JS Handler PHP Binary
31. Lambda function JS Handler PHP Binary PSR-7 bref.php
32. Lambda function JS Handler PHP Binary PSR-7
33. Lambda function JS Handler PHP Binary PSR-7 API Gateway
34. Lambda function JS Handler PHP Binary API Gateway HTTPS FREE SSL!!! PSR-7
35. Things to remember
36. • Application logs are sent to Cloudwatch • PHP is running through the CLI SAPI
37. What we’ll cover
38. • Setting up a new ‘Hello World’ SF 4 site • Setting up a REST API with database migrations • Converting an existing site to Lambda • Retro-fitting to an older Symfony site • Cron tasks • Performance
39. Hello World
40. • Install Symfony • Install Bref • Set up some config • Deploy • Explore the environment • Fix any issues
54. use the Symfony adapter
56. includes Lambda env vars package name
59. create .bref.yml with build hooks
73. click me
74. oh noes
78. let’s refresh…
79. oh noes again!
82. let’s refresh again…
85. • Installed Symfony • Installed Bref • Copied config from the docs • Deployed • Had a look around • Used Cloudwatch to help us debug
86. That’s great, but how about doing something useful?
88. • Install Api-Platform • Install Bref • Add a database connection • Run Symfony commands • Get rid of the ugly Cloudfront hostname
99. • Change logs directory in Kernel class • Configure includes in serverless.yml • Replace contents of bref.php with Symfony adapter • Add cache warmup to .bref.yml
100. add /dev prefix to routing
101. Setting up the database connection
102. Lambda function JS Handler PHP Binary PSR-7 API Gateway
103. Lambda function JS Handler PHP Binary PSR-7 API Gateway
104. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store
105. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store VPC
106. ${env:DATABASE_URL}
109. Running Symfony commands with bref
111. invoke Lambda function
112. Symfony command
115. entry point works!
116. get empty collection
117. post a new book
118. yay!!!
119. That’s great, but I have a really cool domain name…
125. we can remove /dev route prefix :)
126. w00t!
127. • Installed Symfony • Installed Api-Platform • Installed Bref • Configured the standard files • Added a database connection through environment vars • Ran Symfony commands • Added a custom domain name via the AWS GUI
128. That’s great, but my site is more than just a REST API…
133. vich/uploader-bundle
134. • Install Bref to an existing site • Move assets to a CDN • Move session storage to a centralised location • Add image uploading
138. • Change logs directory in Kernel class • Configure includes in serverless.yml • Replace contents of bref.php with Symfony adapter • Add cache warmup to .bref.yml
144. webpack.config.js
145. process.env.ASSETS_BUCKET_NAME
149. ${env:ASSETS_BUCKET_NAME}
152. Symlinking bug :(
157. %env(ASSETS_BUCKET_NAME)%
158. refresh… :)
160. got kicked, lol
161. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store
162. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store Sessions
163. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store JS Handler PHP Binary PSR-7 Sessions Sessions
164. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store JS Handler PHP Binary PSR-7 Sessions
174. migrations worked!
175. where are my images?
176. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store
177. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store
178. Lambda function JS Handler PHP Binary PSR-7 API Gateway Data Store File Store
179. original value
180. point to CDN instead
183. create a global twig variable
185. pretty kitties!
186. Uploading new images
187. Use pre-signed URLs
188. Client Server Amazon S3
189. Client Server Amazon S3 Get Pre-Signed URL
190. Client Server Amazon S3 Get Pre-Signed URL Get Pre-Signed URL
191. Client Server Amazon S3 Get Pre-Signed URL Get Pre-Signed URL One-time use URL
192. Client Server Amazon S3 Get Pre-Signed URL Get Pre-Signed URL One-time use URL One-time use URL
193. Client Server Amazon S3 Get Pre-Signed URL Get Pre-Signed URL One-time use URL One-time use URL PUT file to One-time use URL 200 OK
194. Client Server Amazon S3 Get Pre-Signed URL Get Pre-Signed URL One-time use URL One-time use URL PUT file to One-time use URL 200 OK Update record
195. Client Server Amazon S3 Get Pre-Signed URL Get Pre-Signed URL One-time use URL One-time use URL PUT file to One-time use URL 200 OK Update record Delete previous file
196. we can delete all of this
197. and this
200. we only want /uploads to be writeable
201. let’s re-create this in yaml
212. • Added Bref to an existing site • Fixed assets by moving them to a CDN • Added serverless-s3-uploads plugin • Configured CORS & bucket security in serverless.yml • Moved session storage to the database • Used pre-signed URLs for image uploading
213. That’s really cool, but I need to run cron tasks in PHP
218. { “cli”: “app:dump-lambda — message=Hello” }
221. But my site isn’t Symfony 4!
