CI/CD Integration with CodeBuild: Auto-Deploy Lambda Function

Create CodeBuild Project

Next step, we need to create a CodeBuild Project to integrate with github webhook to auto deploy lambda functions when a new commit is detected.

1. Go to https://us-east-1.console.aws.amazon.com/codesuite/codebuild/start?region=us-east-1

2. Click Create project

3. Fill your Project configuration, Source

4. Choose source: S3/GitHub, at here we choose GitHub

5. At Environment, we select lambda to build image

6. Choose Operating system: Amazon Lunix

7. Choose Runtime(s): Java 11

8. Choose Image: aws/codebuild/amazonlinux-aarch64-lambda-standard:corretto11

9. On Buildspec we select Insert build commands and choose Switch to editor

10. It see like this, now we need config pipeline using code below to build successfully project

    version: 0.2
    phases:
    install:
        runtime-versions:
        java: corretto11
        maven: 3.9.6
        # commands:
        #   - export JAVA_HOME=$(readlink -f /usr/bin/java | sed "s:bin/java::")
        #   - export PATH=$JAVA_HOME/bin:$PATH
    build:
        commands:
        - ls
        - cd note-app-serverless/aws-serverless-note-app
        - ls -lrt
        - mvn clean package -DskipTests=true
        - ls
        # Upload JAR file to S3
        - aws s3 cp target/aws-serverless-note-app-0.0.1-SNAPSHOT.jar s3://cf-templates-1ohbdpx0bstp8-us-east-1/aws-serverless-note-app-0.0.1-SNAPSHOT.jar
        - aws lambda update-function-code --function-name LambdaAddDataFunction --s3-bucket cf-templates-1ohbdpx0bstp8-us-east-1 --s3-key aws-serverless-note-app-0.0.1-SNAPSHOT.jar
        - aws lambda update-function-code --function-name LambdaDeleteNote --s3-bucket cf-templates-1ohbdpx0bstp8-us-east-1 --s3-key aws-serverless-note-app-0.0.1-SNAPSHOT.jar
        - aws lambda update-function-code --function-name LambdaFetchDataFunction --s3-bucket cf-templates-1ohbdpx0bstp8-us-east-1 --s3-key aws-serverless-note-app-0.0.1-SNAPSHOT.jar
        - echo 'Successfully Build new version'
    

aws s3 cp target/aws-serverless-note-app-0.0.1-SNAPSHOT.jar s3://cf-templates-1ohbdpx0bstp8-us-east-1/aws-serverless-note-app-0.0.1-SNAPSHOT.jar

Explain: This command have meaning is coppy .jar file to S3 bucket

• target/aws-serverless-note-app-0.0.1-SNAPSHOT.jar is output file, after run mvn clean package -DskipTests=true
• s3://cf-templates-1ohbdpx0bstp8-us-east-1/aws-serverless-note-app-0.0.1-SNAPSHOT.jar is s3 bucket url, you save file on s3

aws lambda update-function-code –function-name LambdaDeleteNote –s3-bucket cf-templates-1ohbdpx0bstp8-us-east-1 –s3-key aws-serverless-note-app-0.0.1-SNAPSHOT.jar

Explain: This command have meaning is update source for lambda funtion LambdaDeleteNote from jar file, you have puted in s3

Create Pipeline

1. Go to https://us-east-1.console.aws.amazon.com/codesuite/codepipeline/pipelines?region=us-east-1
2. Click Create pipeline

We have complete 4 steps:

• Step 1 :Choose pipeline settings
• Step 2: Add source
• Step 3: Add build
• Step 4:Add deploy
• Step 5: Review and Create

Now, almost set up done, we will test by publish new commit change and pipeline auto execution

Test

Now, inspect source code and make any change to test pipeline work correctly.

    luongtx@daotq1:~/Workspace/GITHUB/aws-handson$ git status
    On branch main
    Your branch is up to date with 'origin/main'.

    Changes not staged for commit:
    (use "git add <file>..." to update what will be committed)

            modified:   note-app-serverless/aws-resource/code-deploy/pipeline.yaml

    no changes added to commit (use "git add" and/or "git commit -a")

Open your CodeBuild Project and Click to detail and view the build console.

If you received response below, pipeline already build completed and lambda function have been update.
