Thumbor S3

Simple Thumbor Docker image that serves image files from an AWS S3 bucket, using the ImageMagick engine. To run, supply the following environment variables for docker run:

• AWS_ACCESS_KEY_ID
• AWS_SECRET_ACCESS_KEY
• AWS_S3_BUCKET
• THUMBOR_KEY

Running It

• Prepare an environment file such as thumbor.env with the following content:

AWS_ACCESS_KEY_ID=<your AWS access key ID>
AWS_SECRET_ACCESS_KEY=<your AWS secret access key>
AWS_S3_BUCKET=<your s3 bucket>
THUMBOR_KEY=<your Thumbor key>

• docker run --name thumbor -p "8888:8888" --env-file=thumbor.env 9gel/thumbor-s3
• Get a URL for a file yourfile.png:
  • docker exec thumbor thumbor-url -k '<your Thumbor key>' -w 400 -e 400 "yourfile.png"
  • You'll get a URL like: /<generated signature>/400x400/yourfile.png
• Access the file:
  • http://<your docker host>:8888/<generated signature>/400x400/yourfile.png

Deploying It

Launch a few Thumbor executables per machine, and put Nginx in front.

With Docker Compose

Here's an example using Docker Compose with files in this repository:

• Edit thumbor.env to fill in your specifics
• docker-compose up
  • You should see the container names. One of those for Thumbor will look like dockerthumbors3_thumbor1_1
• Get a URL for a file yourfile.png:
  • docker exec dockerthumbors3_thumbor1_1 thumbor-url -k '<your Thumbor key>' -w 400 -e 400 "yourfile.png"
  • You'll get a URL like: /<generated signature>/400x400/yourfile.png
• Access the file:
  • http://<your docker host>:8880/<generated signature>/400x400/yourfile.png

Amazon Elastic Beanstalk

Easily deploy to Amazon Elastic Beanstalk in a Multicontainer Docker Environment and take advantage of their auto-scaling feature. You can also put a CDN in front of your setup with CloudFront.

• Follow this Elastic Beanstalk tutorial, using the Dockerrun.aws.json in this repository.
• Define these Environment Properties in Elastic Beanstalk Configuration -> Software Configuration

AWS_ACCESS_KEY_ID
AWS_SECRET_ACCESS_KEY
AWS_S3_BUCKET
THUMBOR_KEY

How It Works

The ENTRYPOINT script:

• Takes the thumbor.conf.tpl template and produces /etc/thumbor.conf with environment variables using 'envtpl'.
• Runs thumbor
