Alternatively, if you do not wish to push to a repository: Export the container to a tarball docker export <CONTAINER ID> > /home/export.tar Move your tarball to new machine Import it back cat /home/export.tar | docker import – some-name:latest
(Copying answer from question) To add an insecure docker registry, add the file /etc/docker/daemon.json with the following content: { “insecure-registries” : [ “hostname.cloudapp.net:5000” ] } and then restart docker.
Latest answer Edit suggested by OhJeez in the comments. docker inspect –format=”{{index .RepoDigests 0}}” $IMAGE Original answer I believe you can also get this using docker inspect –format=”{{.RepoDigests}}” $IMAGE Works only in Docker 1.9 and if the image was originally pulled by the digest. Details are on the docker issue tracker.
If your task is running under a service you can force a new deployment. This forces the task definition to be re-evaluated and the new container image to be pulled. aws ecs update-service –cluster <cluster name> –service <service name> –force-new-deployment

In general, deleting a repository means, that all the tags associated to this repo are deleted. Deleting a tag means, that the association between an image and a tag is deleted. None of … Read more
As of Docker 1.9, You are looking for –build-arg and the ARG instruction. Check out this document for reference. This will allow you to add ARG arg to the Dockerfile and then build with docker build –build-arg arg=2.3 .
For the latest (as of 2015-07-31) version of Registry V2, you can get this image from DockerHub: docker pull distribution/registry:master List all repositories (effectively images): curl -X GET https://myregistry:5000/v2/_catalog > {“repositories”:[“redis”,”ubuntu”]} List all tags for a repository: curl -X GET https://myregistry:5000/v2/ubuntu/tags/list > {“name”:”ubuntu”,”tags”:[“14.04”]} If the registry needs authentication you have to specify username and password … Read more
Docker images are stored as filesystem layers. Every command in the Dockerfile creates a layer. You can also create layers by using docker commit from the command line after making some changes (via docker run probably). These layers are stored by default under /var/lib/docker. While you could (theoretically) cherry pick files from there and install … Read more
You need to tag your image correctly first with your registryhost: docker tag [OPTIONS] IMAGE[:TAG] [REGISTRYHOST/][USERNAME/]NAME[:TAG] Then docker push using that same tag. docker push NAME[:TAG] Example: docker tag 518a41981a6a myRegistry.com/myImage docker push myRegistry.com/myImage
