Nginx Image Server

Docker Repository on Quay.io Build Status

Docker Image for Nginx server for image processing with ngx_small_light. It supports resizing/cropping/formatting (png, webp...etc) of images stored in local storages or AWS S3.

Please see https://github.com/cubicdaiya/ngx_small_light for more information about image processing.

SUPPORTED TAGS

  • latest
  • Nginx 1.10.0
  • ngx_small_light 0.7.3
  • ImageMagick 6.8.6-8 (Q16) with WebP support

HOW TO USE

# Get the docker image
$ docker pull quay.io/wantedly/nginx-image-server

# Fetch an example image to try image-processing local image
$ curl -L https://raw.githubusercontent.com/wantedly/nginx-image-server/master/examples/example.jpg > \
    /tmp/example.jpg

# Start the image server
$ docker run \
    --rm \
    -it \
    --name nginx-image-server \
    -p 80:80 \
    -p 8090:8090 \
    -v /tmp/example.jpg:/var/www/nginx/images/example.jpg \
    -e "SERVER_NAME=image.example.com" \
    -e "S3_HOST=<YOUR-BUCKET-NAME>.s3.amazonaws.com" \
    quay.io/wantedly/nginx-image-server:latest

Then you can try image-processing by accessing

  • Images in S3: http://<YOUR-SERVER.com>/small_light(dh=400,da=l,ds=s)/<PATH-TO-IMAGE-IN-S3>
  • Images in Local: http://<YOUR-SERVER.com>/local/small_light(dh=400,da=l,ds=s)/images/example.jpg

And http://<YOUR-SERVER.com>:8090/status retruns the nginx status.

Custom configuration

You can build a docker image includes your own nginx.conf:

FROM quay.io/wantedly/nginx-image-server
COPY nginx.conf /etc/nginx/nginx.conf

Then build with docker build -t your-nginx-image-server . and run:

$ docker run \
    -d \
    --name your-nginx-image-server \
    -p 80:80 \
    your-nginx-image-server

Be sure to include daemon off; in your custom configuration to run Nginx in the foreground. Otherwise your container will stop immediately after starting.
