Why Docker resets connection upon pushing an image to a private registry?

We have a Docker private registry, listening on a non-default port (specified in our docker run command). However, our attempts to push an image (either pre-built, or built via Jenkins) fail with an error message (see bold below). Help at your earliest convenience will be much appreciated. We simply installed Docker on the machine and […]

REST API for Docker Hub Registry

The REST API for registry.hub.docker.com does not seem to match the documented API. For example, curl -k https://registry.hub.docker.com/v1/repositories/busybox/tags returns: [{“layer”: “4986bf8c”, “name”: “latest”}, {“layer”: “2aed48a4”, “name”: “buildroot-2013.08.1”}, … ] But https://docs.docker.com/reference/api/registry_api/#tags says it should return a map of tag -> id.

local docker Repos keep getting bigger and bigger

i make my first steps with docker repos in artifactory (5.1.3) and theres something that scares me a little bit. I pushed different tags from the same docker image (abaout 500MB) to a repo. I’d expected that storage use and size of the repo would stay at about 500 MB. But with 5 Image-Versions in […]

Cannot get a valid response from Docker Registry remote API

I’m using Nodejs & request to form my API calls, I can make API calls directly to a UnixSocket with it however it fails every attempt when requesting from the Docker registry container I have running, so I believe it’s the fault of my registry configuration. I’ve set it up out of the box just […]
