install docker container - docker run - invalid reference format

From the docker quickstart terminal on Windows 7 64-bit, I'm following the instructions to install this docker container. I run the command,

docker run http://wiki.openstreetmap.org/wiki/nominatim


and I get this error:

c:program filesdocker toolboxdocker.exe: invald reference format.


I can't find any information about this error related to this container.

The image name that you have specified to pull and run is wrong. The image name should be mediagis/nominatim.

mediagis/nominatim

Your docker run command should be

docker run mediagis/nominatim


It is not necessary to pull the image first and run it. By default docker run first tries to find such image in your machine if not then it tries to download from docker repository.

If you specify URL format it directly downloads from private repo if such image is not found in your machine.

Brief Explanation:

Docker takes whatever that is in form of url as an image and the reason for this is sometimes you may want to run image from your private repository. So here http://wiki.openstreetmap.org/wiki/nominatim is considered as an image called wiki/nominatim from a private repo called wiki.openstreetmap.org by docker and the format of private repo and image is wrong . It should be <domain.com>/image:tag where tag is optional. You are not supposed to provide protocol (http://). See this for reference Hence the error is thrown as invalid reference format.

wiki/nominatim

wiki.openstreetmap.org

<domain.com>/image:tag

tag

If you would have given as docker run wiki.openstreetmap.org/wiki/nominatim it would have tried to download image called wiki/nominatim from wiki.openstreetmap.org private repo with latest tag. Since no such repo and image exists it reports Error response from daemon: error parsing HTTP 404 response body as the url throws 404: Not Found when docker daemon tries connecting to it.

docker run wiki.openstreetmap.org/wiki/nominatim

wiki/nominatim

wiki.openstreetmap.org

latest

404: Not Found

References:

Note: Unless you specify tag name which is optional docker always downloads latest tag from repo.

latest

You need to pull the image first , then run the container. according to your docker command, you are trying to access a website, it is not a docker container image. so that's why it is giving you the invalid reference format.

docker run http://wiki.openstreetmap.org/wiki/nominatim

does non make any sense syntactically ...

In any case the correct command to get the latest image is:

sudo docker pull mediagis/nominatim:3.1

Notice that each version has its own installation instructions (versions prior to 3.1 were structurally different), so please do refer to the appropriate section:

https://hub.docker.com/r/mediagis/nominatim/tags/

However I do agree with you that

docker run --restart=always -p 6432:5432 -p 7070:8080 -d -v /home/me/nominatimdata/postgresdata:/var/lib/postgresql/9.5/main nominatim sh /app/start.sh

Should be

docker run --restart=always -p 6432:5432 -p 7070:8080 -d -v /home/me/nominatimdata/postgresdata:/var/lib/postgresql/9.5/main mediagis/nominatim sh /app/start.sh

instead. The installation instructions need updating there.
