Automate AWS S3 deployment with BitBucket (or Github) and Wercker

cd-aws-s3-wercker.md

This tutorial explains how to deploy automatically from bitbucket (or github) to AWS S3.

Create a bitbucket repository (public or private).

Add this repo on Wercker

• Go to Create Application
• Select use bitbucket (or github)
• Choose your repo
• For the next questions, choose the default answers

Add a file wercker.yml in your project

box: debian

deploy:
    steps:
        - s3sync:
            key-id: $S3_ACCESS_KEY_ID
            key-secret: $S3_SECRET_KEY
            bucket-url: $S3_BUCKET_NAME

Get your AWS credentials

• on AWS, go to Security Credentials
• Go to Access Keys (Access Key ID and Secret Access Key)
• Create a new key and keep the Access key ID and the Secret Access Key in a safe place.

Setup Deployment on Wercker

• on Wercker, go to the settings of your app
• in Deploy targets, click on add deploy target and choose custom deploy
• Target name can be production
• Select Autodeploy
• Branch name is master

Under Environment variables

• Click on add new variable and create a new environement variable with the name S3_ACCESS_KEY_ID and your access key id as text
• Create another new variable with the name S3_SECRET_KEY and your secret access key as text
• Create another variable with the name S3_BUCKET_NAME and s3://example.com/bucket/ as text (change example.com with the name of your bucket) - make sure the path ends with a trailing slash, subdirectories can be used.

Push your files to bitbucket

Wercker should run the build (that does nothing so far) and deploy on s3.
