I am a beginner with docker. I want to run a docker engine api call from within one of my docker containers - specifically list all images (images/json endpoint). I am trying to troubleshoot this, and want to see the issue live from the command line.
I am struggling to figure out what is the host I should be using in the curl request form within a container (this post seems to be related, but I tried all what is suggested there without success). Tried container ip (taken from ifconfig), localhost, service name as defined in the docker-compose yml file. Nothing works.
This post seem to instruct how to do that. But again the suggestion does not work for me: curl --unix-socket /var/run/docker.sock http://images/json. This returns {"message":"page not found"}
Any help would be highly appreciated.
Argh... found the answer here:
curl --unix-socket /run/docker.sock http://docker/images/json finally works for me.
This post talks about the need for "docker" or another dummy host being added starting from curl version 7.4. Older versions did not require it.
