`docker.env`
```bash
AWS_ACCESS_KEY_ID=xxx
AWS_DEFAULT_REGION=ap-northeast-1
AWS_SECRET_ACCESS_KEY=xxx
```
### docker-compose

$ docker-compose build
$ docker-compose --rm run serverless sh
sh-4.2# bundle config set path 'vendor/bundle'

use https://github.com/customink/ruby-vips-lambda
```
$ git clone https://github.com/customink/ruby-vips-lambda.git
$ cd ruby-vips-lambda
$ ./bin/deploy
```
#### If you deploy to layer other region(not us-east-1)
- change `AWS_DEFAULT_REGION` in `ruby-vips-lambda/bin/deploy`
```
#!/bin/bash
set -e
./bin/build
export VIPS_VERSION=$(cat share/VIPS_VERSION)
export LAYER_NAME="rubyvips${VIPS_VERSION//./}-27"
# change here
export AWS_REGION=${AWS_REGION:=ap-northeast-1}
aws lambda publish-layer-version \
--region $AWS_REGION \
--layer-name $LAYER_NAME \
--description "Libvips for Ruby FFI." \
--zip-file "fileb://share/libvips.zip"
