  1 | # Build and deploy Rust binary to Lambda
  2 | 
  3 | ## TL;DR
  4 | 
  5 | - I reccomend ZIP deploy to `provided.al2` than container deploy, because of faster cold start time.
  6 | - To avoid shared library version mismatch, run `cargo build` on Amazon Linux 2 environment.
  7 | - Using CodeBuild may be the simplest way. You can also build Arm64 binary if you prefer it.
  8 | - This repository contains [sample buildspec.yml](./buildspec.yml) for this purpose.
  9 | 
 10 | ## Deploy Rust binary to AWS Lambda
 11 | 
 12 | At the time of writing (Nov, 2021), Amazon AWS supports two ways to deploy Rust binary to AWS Lambda.
 13 | 
 14 | - ZIP deploy to custom runtime `provided.al2`
 15 | - Container image deploy
 16 | 
 17 | Both work well, but cold start time is differ.
 18 | In my measurement, cold start time of ZIP deploy is around 250ms, while container deploy is around 600ms.
 19 | (Measurement is end-to-end, it's time includes network latency, TLS handshake, API gateway processing time, etc.)
 20 | 
 21 | ## How to build binary for `provided.al2` runtime
 22 | 
 23 | If you have a Linux system, you can run `cargo build` to get binary. But sometimes you get error on runtime like
 24 | 
 25 | ```txt
 26 | /lib64/libc.so.6: version `GLIBC_2.18` not found
 27 | ```
 28 | 
 29 | This error is occured becasuse your system has newer version of libc than Amazon Linux 2 runtime.
 30 | 
 31 | So, I recommend to run `cargo build` on Amazon Linux 2 environment.
 32 | There are a few way to do it, I think [AWS CodeBuild](https://aws.amazon.com/codebuild/) is the simplest way.
 33 | Since CodeBuild provides Amazon Linux 2 as the standard build environment, you only need to place `buildspec.yml` file in the repository.
 34 | 
 35 | ## Using AWS CodeBuild
 36 | 
 37 | - Write `buildspec.yml`
 38 | - Prepare S3 bucket where built binary will be placed.
 39 | - Create CodeBuild project
 40 | - Deploy to Lambda
 41 | 
 42 | First, place following `buildspec.yml` in your repository root directory. Make sure, `YOUR_PROJECT_NAME` is for your project.
 43 | 
 44 | ```yml
 45 | version: 0.2
 46 | 
 47 | env:
 48 |   variables:
 49 |      PATH: "/root/.cargo/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/codebuild/user/bin"
 50 | phases:
 51 |   install:
 52 |     commands:
 53 |       # Install rust toolchanin
 54 |       - curl -sSf https://sh.rustup.rs | sh -s -- -y --profile minimal
 55 |   build:
 56 |     commands:
 57 |       # build Rust binary
 58 |       - cargo build --release
 59 |       # binary name must be "bootstrap" for Lambda custom runtime
 60 |       - mv target/release/YOUR_PROJECT_NAME bootstrap
 61 |       # strip & check size, dependencies
 62 |       - strip --strip-all bootstrap
 63 |       - size bootstrap
 64 |       - ldd bootstrap
 65 | artifacts:
 66 |   files:
 67 |     - bootstrap
 68 |     # - add other resources such as CSS, Javascript assets, etc.
 69 |   #discard-paths: yes
 70 | ```
 71 | 
 72 | Second, prepare S3 bucket in same region with Lambda and CodeBuild. If you have already some bucket, you can use it. Or make new one.
 73 | 
 74 | Third, create new CodeBuild project.
 75 | 
 76 | - `Source` section: \
 77 |   Select source code repository of your project.
 78 |   CodeBuild can fetch CodeCommit, GitHub, Bitbucket repositories directly, or you should pack all source codes into ZIP and upload it to S3.
 79 | - `Environment` section:
 80 |   - Select `Managed Image`
 81 |   - Operating system - `Amazon Linux 2`
 82 |   - Runtime - `Standard`
 83 |   - Image - `aws/codebuild/amazonlinux2-aarch64-standard:2.0` or `aws/codebuild/amazonlinux2-x86_64-standard:3.0` (as of writing; Newer image will come)
 84 |   - Environment type - `Linux`
 85 |   - Privileged - `disable`
 86 |   - Service role - If you unsure, select `New service role` and name it. If you use existing role, the role needs S3:PutObject permision to the bucket mentioned above.
 87 | - `Buildspec` section: \
 88 |   `Use a build file` and keep `Buildspec name` as blank, if you place buildspec.yml on your repository root.
 89 |   In other case, specify where your buildspec.yml is.
 90 | - `Batch configuration` section: \
 91 |   Disable `Define batch configuration`
 92 | - `Artifacts` section:
 93 |   - Set type as `Amazon S3` and specify `Bucket name` as the S3 bucket mentioned above.
 94 |   - `Name` is ZIP file name like lambda_deploy.zip
 95 |   - `Path` is directory of ZIP file. ZIP file will be placed at `s3://<Bucket name>/<Path>/<Name>`
 96 |   - `Namespace` - None
 97 |   - `Artifacts packaging` - Select `ZIP`
 98 | 
 99 | Congratulations! You can now `Start build` and get ZIPed Rust binary in S3 bucket.
100 | 
101 | Finally you can deploy binary to Lambda. Since ZIP is already on S3 bucket, `Upload from` - `Amazon S3 location` in the Lambda console.
102 | 
103 | ## Another way to build - run Amazon Linux 2 Docker container on your machine
104 | 
105 | If you are familier with Docker, you can build Rust binary with Amazon Linux 2 container image.
106 | 
107 | First, build Amazon Linux 2 container image including Rust compiler toolchain with following Dockerfile.
108 | 
109 | ```Dockerfile
110 | FROM amazonlinux:2
111 | 
112 | # Setup build environment
113 | RUN mkdir -p /build/src && \
114 |     yum update -y && \
115 | # Add required packages
116 |     yum install -y awscli gcc openssl-devel tree zip && \
117 | # Install rust with rustup
118 |     curl -sSf https://sh.rustup.rs | sh -s -- -y --profile minimal
119 | 
120 | # Build environment setting
121 | WORKDIR /build
122 | ENV PATH=/root/.cargo/bin:/usr/sbin:/usr/bin:/sbin:/bin
123 | # Default build command
124 | CMD \
125 |   cargo build --release --target-dir target_al2 && \
126 |   mv target_al2/release/YOUR_PROJECT_NAME bootstrap && \
127 |   strip --strip-all bootstrap && \
128 |   size bootstrap && \
129 |   ldd  bootstrap && \
130 |   zip -9 -j deploy.zip bootstrap
131 | ```
132 | 
133 | Then, run container with mounting source code directory.
134 | 
135 | ```console
136 | $ cd /your/cargo-project/top
137 | $ ls
138 | Cargo.lock  Cargo.toml  src
139 | $ docker run -it --rm \
140 |   -v ~/.cargo/registry:/root/.cargo/registry:z \
141 |   -v .:/build:z \
142 |   BUILD_CONTAINER_NAME
143 | ...
144 | $ ls
145 | Cargo.lock  Cargo.toml  bootstrap  deploy.zip  src  target_al2
146 | ```
147 | 
148 | ## Arm64 build
149 | 
150 | [AWS released Graviton2 processor (Arm64) for Lambda](https://aws.amazon.com/blogs/aws/aws-lambda-functions-powered-by-aws-graviton2-processor-run-your-functions-on-arm-and-get-up-to-34-better-price-performance/)
151 |  on Sep, 2021.
152 | Graviton2 Lambda function is cost effective option, you may interested in it.
153 | 
154 | If you use CodeBuild, all pieces for Arm64 support are available!
155 | 
156 | - CodeBuild already [supports Graviton2](https://aws.amazon.com/about-aws/whats-new/2021/02/aws-codebuild-supports-arm-based-workloads-using-aws-graviton2/)
157 | - Rust compiler supports [aarch64-unknown-linux-gnu as tier 1](https://doc.rust-lang.org/rustc/platform-support.html#tier-1-with-host-tools)
158 | - Lambda function [powered by Graviton2 prcessor](https://aws.amazon.com/about-aws/whats-new/2021/09/better-price-performance-aws-lambda-functions-aws-graviton2-processor/)
159 | 
160 | You only switch CodeBuild image as
161 | `aws/codebuild/amazonlinux2-aarch64-standard` and Lambda function architecture as `arm64`.

194 | 
195 | ## Create deploy ZIP file
196 | 
197 | As of writing (Nov, 2021), we have two options to run Rust on AWS Lambda: [Amazon Linux 2 custom runtime](https://docs.aws.amazon.com/lambda/latest/dg/runtimes-custom.html) or Docker container image.
198 | 
199 | I recommend ZIP deploy to Amazon Linux 2 custom runtime (`provided.al2`) because it's faster cold start time than container image.
200 | 
201 | To build Amazon Linux 2 compatible binary, see [Deploy.md](./Deploy.md) for more details.
202 | 
203 | ## Setup AWS Lambda & function URLs
204 | 
205 | - Create lambda function with `provided.al2` custom runtime. Choose "Provide your own bootstrap on Amazon Linux 2" .
206 | - Upload ZIP file described above.
207 | - IAM role, memory settings, etc. are as your demands. \
208 |   As sample code above consumes only 30MB of memory, many simple Rust app can fit in 128MB setting.
209 | - Create function URL, then you can call your Lambda function with `https://<url-id>.lambda-url.<region>.on.aws`
210 | - You can use CloudFront for custom domain.
211 | 
212 | ## Setup AWS Lambda & API gateway
213 | 
214 | ### Lambda
215 | 
216 | - Create lambda function with `provided.al2` custom runtime. Choose "Provide your own bootstrap on Amazon Linux 2" .
217 | - Upload ZIP file described above.
218 | - IAM role, memory settings, etc. are as your demands. \
219 |   As sample code above consumes only 30MB of memory, many simple Rust app can fit in 128MB setting.
220 | 
221 | ### API Gateway (HTTP)
222 | 
223 | - Create HTTP API
224 | - Create single route "$default" and attach Lambda integration. Make sure, payload format version is "2.0"
225 | 
226 | ### API Gateway (REST)
227 | 
228 | - Create REST API
229 | - Create two resources:
230 |   - ANY method on route `/` and attach Lambda proxy integration.
231 |   - ANY method on route `/{proxy+}` and attach Lambda proxy integration.
232 | - In settings tab, add `*/*` binary media type.
233 | - Then, deploy API to stage.
