How to invoke AWS CLI command from CodePipeline? - amazon-web-services

Question

I want to copy artifacts from S3 bucket in Account 1 to S3 bucket in Account 2. Though I was able to setup replication but I want to know whether there is a way to invoke AWS CLI command from within a pipeline.
Can it be invoked using Lambda function? If yes, any small sample script will be helpful.

Answer 1

Yes, you can add a Lambda Invoke action to your pipeline to call the copyobject API. The core part of the Lambda function is as follow.
exports.copyRepoToProdS3 = (event, context) => {
const jobId = event['CodePipeline.job'].id
const s3Location = event['CodePipeline.job'].data.inputArtifacts[0].location.s3Location
const cpParams = JSON.parse(event['CodePipeline.job'].data.actionConfiguration.configuration.UserParameters)
let promises = []
for (let bucket of prodBuckets) {
let params = {
Bucket: bucket,
CopySource: s3Location['bucketName'] + '/' + s3Location['objectKey'],
Key: cpParams['S3ObjectKey']
}
promises.push(s3.copyObject(params).promise())
}
return Promise.all(promises)
.then((data) => {
console.log('Successfully copied repo to buckets!')
}).catch((error) => {
console.log('Failed to copy repo to buckets!', error)
})
}
