New to docker and I'm using Windows 7 SP1. It looks like docker is running fine in my machine as I have tried running hello-world by command docker run hello-world as instructed in the tutorial and got expected result. Now all I'm trying to do is create a docker image for a .net core console app. My app built and ran. but while building docker image by command docker build -t myapp . I get the below error
error during connect: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.30/build?buildargs=%7B%7D&cachefrom=%5B%5D&cgroupparent=&cpuperiod=0&c

duke&target=&ulimits=null: open //./pipe/docker_engine: The system cannot find the file specified. In the default daemon configuration on
Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
Below my Dockerfile
FROM microsoft/dotnet:1.1-runtime-nanoserver
WORKDIR /DotNetConsole
COPY /bin/Debug/netcoreapp1.1/publish/ .
ENTRYPOINT ["dotnet", "DotNetConsole.dll"]
I could get around this problem by starting the "Docker QuickStart Terminal" installed with the docker tools, and running the commands for building the docker images from there.
If I used GIT BASH instead of the Docker QuickStart Terminal to execute the commands, I would get this kind of error. So it seems that if the commands are not executed from the Docker terminal itself, these errors show up.

Docker was running properly for years. I now updated it then it stopped working.
Even simple image ls command returns error.
C:\WINDOWS\system32>docker image ls error during connect: Get "http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/images/json": EOF
When I search and run an image in docker-desktop, it runs without error, but I can not run docker commands in command line.
I have tried uninstalling and reinstalling it several times, but no success.
I am using Win 10 pro and Docker Desktop service is running in services.
How can I fix it?
I created a docker image on my red hat Linux .
The base image is a centos image and has a application installed on it. I am able to run the image on dockers on multiple Linux machines .
I then saved the image and then copied the image on windows server 2019 machine with all latest updates installed .
I then loaded the image using
docker load -i img.tar
When I try to run the container I get the following error
PS C:\Users\manish\Desktop\docker> docker run -dit --name manish22ct docker_22_oct:1.0

Answering my own question to the best of my ability in case it helps someone .
I found that the docker daemon for Linux and windows are different. For Linux
its provided by dockerhub but for windows its provided by Microsoft . Some images I downloaded from dockerhub like Cassandra doesn't work directly on windows too but run perfectly fine on Linux .
Sometimes these images run too .
In case you image is not running on both there is something in your image layer that is hindering your run on windows .
For windows I found that RUN command is something you should avoid .
Check your dockerfile and remove all RUN commands and move all those in to a shell file say runMe.sh. At the end of all your commands in this shell file don't forgot to include tail -f /dev/null
Since only one CMD is allowed in dockerfile
CMD ( /runMe.sh > /runMe.log 2>&1 )
is the only thing that would remain of RUN and CMD set of instructions in your dockerfile .
Create your image . It would run on both Windows and Linux .
I'm new to using Docker (never used it before) and I'm running into these errors:
I installed the Docker for Windows and following the steps on this
tutorial, but Docker Desktop doesn't load up for me at all.
I tried to run the docker pull hello-world command but I'm getting the error: The system cannot find the file specified. In the default daemon configuration on Windows, the docker client must be run elevated to connect. This error may also indicate that the docker daemon is not running.
How do I fix this? Thanks
I have the following basic Dockerfile:
FROM mcr.microsoft.com/windows/servercore:1903
CMD echo Hello World!
When I run the command:
docker build -t latest . or docker build .
My terminal hangs forever and it seems like nothing is being done.
However, if I run:
docker pull mcr.microsoft.com/windows/servercore:1903
I can pull the image from the repository.
I'm not sure what I'm doing wrong, or how to fix it. The build command doesn't seem to have a verbose option, and I need a docker container running Windows.
I'm using Docker in Windows 10 Pro and its configured to use Windows containers.
Check which directory do you execute your commands from. You shall be executing them from directory where DOCKERFILE is located and nothing else. If you execute say from root of C drive or any other location with big number of files then docker as a first step will try to zip all of them up and then send to a builder and hence delays.
Complete docker noob here, i installed docker desktop on windows - Trying to follow the commands on this link to setup OSRM backend on my machine. i've downloaded the dataset for india(india-latest.osm.pbf) to D:/docker
and am running the commands from that location
docker run -t -v "${PWD}:/data" osrm/osrm-backend osrm-extract -p /opt/car.lua /data/india-latest.osm.pbf
fails with
[error] Input file /data/india-latest.osm.pbf not found!
i just don't understand WHY it doesn't work. according to osrm documentation of the docker command -
The file /data/india-latest.osm.pbf inside the container is referring
to "${PWD}/india-latest.osm.pbf" on the host.
but it's not the case,i am running from d:/docker so it should find india-latest.osm.pbf no problem. This is really really confusing to me even though it must be so basic
it was due to a bug in docker https://github.com/docker/for-win/issues/1712
when you change password it silently fails for commands that access the host filesystem on windows until you reauthenticate
