iipsrv

A single-container deployment of IIPImage, running on nginx with FastCGI.

(Forked from iiip-nginx-single.)

Configuration

When using this image, either on its own or with the included docker-compose.yml, take note of the following environment variables:

Variable	Purpose	Default	Notes
FILESYSTEM_PREFIX	path to the image file directory	none (but see below under "Image files")	must include trailing slash
LOGFILE	IIPImage log output	/dev/stdout (in Dockerfile)
CORS	CORS Access-Control-Allow-Origin header value	* (in docker-compose.yml; none in Dockerfile)

See the IIPImage docs for a full list of environment variables.

Notes for developers

Default development configuration

Building and running

To build and run the container based on the configuration in docker-compose.yml:

docker-compose build --pull
docker-compose up

Note that nginx/IIPImage runs on port 80, and is exposed on host port 80.

Image files

By default, the iipsrv-entrypoint.sh script will cause files to be served from the test/data directory.

You can override this mount by passing a $FILESYSTEM value to the container; see below under "Custom configuration".

Testing

To test that the container has come up correctly, using the image file test/data/test.tif:

curl -v 'http://localhost/iiif/test.tif/info.json'

This should produce a IIIF information response in JSON format, e.g.:

{
  "@context" : "http://iiif.io/api/image/2/context.json",
  "@id" : "http://localhost/iiif/test.tif",
  "protocol" : "http://iiif.io/api/image",
  "width" : 2769,
  "height" : 3855,
  "sizes" : [
     { "width" : 173, "height" : 240 },
     { "width" : 346, "height" : 481 },
     { "width" : 692, "height" : 963 },
     { "width" : 1384, "height" : 1927 }
  ],
  "tiles" : [
     { "width" : 256, "height" : 256, "scaleFactors" : [ 1, 2, 4, 8, 16 ] }
  ],
  "profile" : [
     "http://iiif.io/api/image/2/level1.json",
     { "formats" : [ "jpg" ],
       "qualities" : [ "native","color","gray","bitonal" ],
       "supports" : ["regionByPct","regionSquare","sizeByForcedWh","sizeByWh","sizeAboveFull","rotationBy90s","mirroring"],
       "maxWidth" : 5000,
       "maxHeight" : 5000
     }
  ]
}

Custom configuration

You also can build an image directly from the Dockerfile and point it at an external image directory.

docker build . -t iipsrv:latest

This builds an image and tag it iipsrv:latest.

docker run --rm \
  --volume /tmp/iipsrv-images:/images \
  --env FILESYSTEM_PREFIX=/images/ \
  --env CORS='*' \
  --publish 127.0.0.1:80:80 \
  iipsrv:latest

Note: FILESYSTEM_PREFIX must have a trailing slash.

This runs the image built above with the following configuration:

1. serving images from a host directory /tmp/iipsrv-images, mounted as /images in the container directory
2. sending CORS header Access-Control-Allow-Origin: *
3. publishing container port 80 (the IIPImage/nginx port) to port 80 on 127.0.0.1
