I am new to docker and have followed https://spring.io/guides/gs/spring-boot-docker/, so far successfully.
docker is installed and running on a different server in my network.
How can I push and run the image directly to that docker-server with maven?
docker-maven-plugin probably does what you want

I've been given a Docker image stored in the gitlab container registry, registry.gitlab.com.
I have a gitlab acount, with a password, and I am able to do a docker login:
docker login registry.gitlab.com
After I do that, I no longer get an authentication error when I try to do a docker command against that registry.
And the documentation for using that registry seems clear:
Go to your project or group’s Packages and registries > Container Registry and find the image you want.
Next to the image name, select Copy.
Use docker run with the image link:
docker run [options] registry.example.com/group/project/image [arguments]
https://docs.gitlab.com/ee/user/packages/container_registry/
But when I run any kind of docker command with the group/project/image I just copied, I just get the "manifest unknown" docker error, which normally indicates that the image is missing or mis-spelled.
So, maybe gitlab is broken, or maybe the gitlab documentation is wrong, or maybe there is something wrong with that particular image, or maybe it doesn't work using docker on WSL through Docker Desktop on Win10, or maybe ... I just haven't set up something correctly.
FWIW, Docker Desktop is a Windows service/application that proxies 'docker' commands in Windows, sending them to a docker instance running on WSL. It's normally transparent. It maintains a local registry, and seems to have some way of connecting to docker hub, but I've never used it with any other registry.
I'd like to pull that image into my local registry. What should I do different?
Can I build Docker images in Windows 10 using Docker For Windows and deploy the it into Openshift?
Should I use Linux Container provided by Docker for Windows?
I think you can. Build a docker image locally then login to Openshift and docker registry, then you should be able to push the image to registry.
You can find instructions on how to push the image to the internal image registry of OpenShift so it can be deployed at:
http://cookbook.openshift.org/image-registry-and-image-streams/how-do-i-push-an-image-to-the-internal-image-registry.html
I have installed docker in a system which has no connection to Internet so to run an image with docker, I had to download a simple image from this and from another system. Then I put this image in my offline system in this path : C:\Users\Public\Documents\Hyper-V\Virtual hard disks
but when I run docker run hello-world in cmd I see this message:
Unable to find image 'hello-world:latest' locally
and tries to download hello-world image form Internet but it has to no connection to the Internet so it field. Now I want to know where I should put my images in to be visible to docker?
You can do it the easy way without messing around with folders, by exporting the docker image from any other machine with access to internet:
pull the image on a machine with internet access.
$docker pull hello-world
save that image to a .tar file.
$ docker save --output hello-world.tar {your image name or ID}
copy that file to any machine.
load the .tar file to docker.
$docker load --input hello-world.tar
Check out:
https://docs.docker.com/engine/reference/commandline/image_save/
https://docs.docker.com/engine/reference/commandline/load/#examples
You are trying to start a container using the dockerfile. You need to first build the image from dockerfile. You can do this via
docker build -t < image name > < path >
You will require the internet connection while building the image.
You can check the image in your system using
docker images
Once you build the docker image you can start the container without internet connection using
docker run < image name >
Also you can export the same image using docker save and docker load functionalities.
Docker runs in a client-server architecture environment just almost like git. It can pull resources from the server online with the client on "your machine".
The command $docker pull hello-world requires connection to the server as part of docker itself.
I'm currently trying to simulate a situation where I can make a docker image after a successful build in TeamCity. I'm using Docker Hub to store my docker images and build them. After that, I web-hooked them to Tutum (Docker Cloud) to eventually push them into Microsoft Azure.
What is the best-practice to make sure there is always a valid docker images in my repo in Docker Hub? I'm running several tests in TeamCity and want to create a Docker image when the build is successful. The TeamCity server is not running a docker host, but my project has a Dockerfile.
Any ideas?
Thanks in advance,
Tim
You can put last successful artifacts on your Dockerfile with ADD command
ADD http://{{TeamcityUrl}}/guestAuth/repository/download/{{BuildName}}/latest.lastSuccessful/dist.zip /{{DockerFolder}}
I have question about docker and using it in development on windows.
I have boot2docker installed and I am able to install a container and access it with ip provided by "boot2docker ip" command. But how should i set up my project on Widnows to edit code of my app in container. for example. I have a container with lighttp and some HTML5 and JS app inside. How can I enable my host machine (Windows) to access this code?
I know i could just make git repository on my local machine and commit code to remote repo on container, but it is not very practical.
If i understand correctly, you're developing inside a docker container and you are trying to get your source from your container?
I guess the easiest way would be to put your source inside a shared volume with the boot2docker and then use scp protocol to get those file back.
On another hand if you're wanting to share a folder between the boot2docker vm and your windows host i suggest you read this tutorial : http://www.incrediblemolk.com/sharing-a-windows-folder-with-the-boot2docker-vm/
Hope it was helpful.
