I'm trying to run Docker in process isolation mode on Windows Server 2019 (Docker Desktop does not work here, my VPS does not support Hyper-V).
I run this in PowerShell (all in Administrator mode)
docker run -it --isolation=process mcr.microsoft.com/windows/servercore:ltsc2019 cmd.exe /c ping 127.0.0.1 -t
Then I get error:
docker: error during connect: In the default daemon configuration on Windows, the docker client must be run with elevated privileges to connect.: Post http://%2F%2F.%2Fpipe%2Fdocker_engine/v1.24/containers/create: open //./pipe/docker_engine: The system cannot find the file specified.
See 'docker run --help'.
I ran command & 'C:\Program Files\Docker\DockerCli.exe' -SwitchDaemon, as suggested here: Docker cannot start on Windows
However, DockerCli.exe does not exist in a clean Docker install:
As suggested here I tried copying the file DockerCli.exe from my local Windows 10 Docker Desktop installation and reran, but then I get:
Unhandled Exception: System.IO.FileNotFoundException: Could not load file or assembly 'Docker.Core, Version=3.0.0.50646, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the file specified.
at Docker.Cli.MainBackendCli.Run(IReadOnlyCollection`1 args)
at Docker.Cli.MainBackendCli.Main(String[] args)
Regardless, copying files from Docker Desktop does not feel like the right approach.
I then ran dockerd in PowerShell since that's the only other executable in that folder:
Since I'm a newbie, I'm not sure if I just started a container and if so, which one, I just see start., but no idea where that comes from or how I can configure it.
UPDATE 1
Based on Peter Wishart's suggestion I tried uninstall-Package -Name docker, but then I get

The pipe access that the error message mentions is a (probably unrelated) issue when docker client is run by non-admin users (see here).
I think the most likely explanation is that the docker service has failed to start.
When you ran dockerd you were actually starting an instance of the daemon - and the line API listen on //./pipe/docker_engine means that the system service hadn't started previously - as the instance you started could create the pipe.
If you stop the running dockerd instance and run:
Get-Service docker | Restart-Service
Get-WinEvent -logname application | where ProviderName -eq docker | sort TimeCreated
You should be able to compare the log output with your manual start of dockerd, and see if any errors are blocking the service from starting.
If the event log records API listen on //./pipe/docker_engine then Get-Service docker should show the service as running, and your docker commands should be ok.
[Edit]
Looks like the uninstall of docker was failing because the service doesn't exist.
Yet, the install is succeeding except for the service installation.
You can re-register the service with &'C:\Program Files\Docker\dockerd.exe' --register-service
Maybe this will fail if the VPS provider is somehow stopping services from being registered?
Another option is to run docker interactively in one shell with &'C:\Program Files\Docker\dockerd.exe' --run-service, and run your docker commands in another shell.
To resolve the issue, I just ran & 'C:\Program Files\Docker\Docker\DockerCli.exe' -SwitchDaemon in PowerShell and quit the Docker desktop and Run Docker Desktop as administrator.
Now open command prompt or powershell and run docker images or dockers ps command. It should work.
Go to PowerShell > run as administrator and run this code:
cd "C:\Program Files\Docker\Docker"
./DockerCli.exe -SwitchDaemon
To resolve the issue, I just ran Two Steps in PowerShell.
First,
cd 'C:\Program Files\Docker\Docker
and then,
/DockerCli.exe' -SwitchDaemon
After that, install the WSL Kernel on your machine, restart the WSL machine, then it is resolved.
This solution helped me
https://github.com/docker/for-win/issues/5919#issuecomment-658815006
cd C:\Program Files\Docker\Docker\resources dockerd.exe
Now execute
'docker version' on a new powershell as administrator
Ok so i followed 2 steps and my problem was resolved:
update wsl kernel, seamingly it is a must because docker needs it and it is not installed by default. so just close all docker realated stuff and run:
wsl --update
command in cmd .
I did what other guys said here:
C:\Program Files\Docker\Docker\DockerCli.exe -SwitchDaemon
and voila!
My solution was removing last edition and installing 4.9.1
One other thing to check is whether you have started the Desktop Client for Windows and accepted the License Agreement. I had restored from an image that hadn't had Docker started and was seeing this error. Nothing worked until I accepted the license.
I checked these boxes and it worked for me:
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
I'm trying to run my Gitlab CI locally using Gitlab-runner and docker before committing to make sure they work okay. But I'm having some strange issues!
Unfortunately I have no choice but to use windows (I've had success in the past on Linux).
Every time I run a job in powershell:
C:/Gitlab-runner/gitlab-runner exec docker npm
I get an error:
Job failed (system failure): Error response from daemon: invalid volume specification: '/host_mnt/c/builds/project-0/Users/Lewsmith/api:C:/Users/Lewsmith/api:ro' (executor_docker.go:921:0s)
I've tried setting docker volumes (nemerous combinations) and builds-dir:
C:/Gitlab-runner/gitlab-runner exec docker --builds-dir /builds --docker-privileged --docker-volumes "/builds:C:/Gitlab-runner/builds" npm
That fails with Error response from daemon: invalid mode: /Gitlab-runner/builds because of the colon after the C..
Can anyone point me in the right direction as I'm stumped?
Using gitlab-runner version 11.5.0
Docker is not fully supported by GitLab Runner on Windows yet.
The workaround is to use Windows Subsystem for Linux and install gitlab-runner there:
curl -L https://packages.gitlab.com/install/repositories/runner/gitlab-runner/script.deb.sh | sudo bash
sudo apt-get install gitlab-runner
gitlab-runner exec docker build
At the moment there isn't official support for the Docker executor in Windows. A work in progress issue is open at the moment, and it looks like some people have managed to get a windows docker executor working to varying success in that merge request.
This specific comment shows how they've managed to get it setup using a custom built gitlab-runner. I'm unsure how this will work with Services however, so YMMV.
I'm brand new to both TeamCity and Docker. I'm struggling to get a Docker container with TeamCity running and usable on my local machine. I've tried several things, to no avail:
I installed Docker for Mac per instructions here. I then tried to run the following command, documented here, for setting up teamcity in docker:
docker run -it --name teamcity-server-instance \
-v c:\docker\data:/data/teamcity_server/datadir \
-v c:\docker\logs:/opt/teamcity/logs \
-p 8111:8111 \
jetbrains/teamcity-server
That returned the following error: docker: Error response from daemon: Invalid bind mount spec "c:dockerdata:/data/teamcity_server/datadir": invalid mode: /data/teamcity_server/datadir.
Taking a different tack, I tried to follow the instructions here - I tried running the following command:
docker run -it --name teamcity -p 8111:8111 sjoerdmulder/teamcity
The terminal indicated that it was starting up a web server, but I can't browse to it at localhost, nor at localhost:8111 (error ERR_SOCKET_NOT_CONNECTED without the port, and ERR_CONNECTION_REFUSED with the port).
Since the website with the docker run command says to install Docker via Docker Toolbox, I then installed that at the location they pointed to (here). I then tried the
docker-machine ip default
command they suggested, but it didn't work, error "Host does not exist: "default"". That makes sense, since the website said the "default" vm would be created by running Docker Quickstart and I didn't do that, but they don't provide any link to Docker Quickstart, so I don't know what they are talking about.
To try to get the IP address the container was running on, I tried this command
docker inspect --format='{{.Name}} - {{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps -aq)
That listed the names of the running containers, each followed by a hyphen, then nothing. I also tried
docker ps -a
That listed running contaners also, but didn't give the IP. Also, the port is blank, and the status says "exited (130) 4 minutes ago", so it doesn't seem like the container stayed alive after starting.
I also tried again with port 80, hoping that would make the site show at localhost:
docker run -it --name teamcity2 -p 80:80 sjoerdmulder/teamcity
So at this point, I'm completely puzzled and blocked - I can't start the server at all following the instructions on hub.docker.com, and I can't figure out how to browse to the site that does start up with the other instructions.
I'll be very grateful for any assistance!
JetBrains now provides official docker images for TeamCity. I would recommend starting with those.
The example command in their TeamCity server image looks like this
docker run -it --name teamcity-server-instance \
-v <path to data directory>:/data/teamcity_server/datadir \
-v <path to logs directory>:/opt/teamcity/logs \
-p <port on host>:8111 \
jetbrains/teamcity-server
That looks a lot like your first attempt. However, c:\docker\data is a Windows file path. You said you're running this on a mac, so that's definitely not going to work.
Once TeamCity starts, it should be available on port 8111. That's what -p 8111:8111 part of the command does. It maps port 8111 on your machine to port 8111 in the VM Docker for Mac creates to run your containers. ERR_CONNECTION_REFUSED could be caused by several things. Two most likely possibilities are
TeamCity could take a little while to start up and maybe you didn't give it enough time. Solution is to wait.
-it would start the TeamCity container in interactive mode. If you exit out of the terminal window where you ran the command, the container will also probably terminate and will be inaccessible. Solution is to not close the window or run the container in detached mode.
There is a good overview of the differences between Docker for Mac and Docker Toolbox here: Docker for Mac vs. Docker Toolbox. You don't need both, and for most cases you'll want to use Docker for Mac for testing stuff out locally.
I am trying to integrate docker into my CI platform. After getting this working properly with a Docker-in-a-docker solution, I came across a blog post by one of the Docker maintainers, where he says that instead of using a Docker-in-a-docker solution for my CI, I should instead simply mount the /var/run/docker.sock to my CI container.
https://jpetazzo.github.io/2015/09/03/do-not-use-docker-in-docker-for-ci/
Simply put, when you start your CI container (Jenkins or other), instead of hacking something together with Docker-in-Docker, start it with:
docker run -v /var/run/docker.sock:/var/run/docker.sock ...
So I tried this. I ran the following command:
docker run -p 8080:8080 -p 50000:50000 -v /var/run/docker.sock:/var/run/docker.sock jenkins
Using jenkins as my CI container.
When running the above command, jenkins starts up properly, and I can jump into the container to see that the docker.sock file is located in the /var/run/ path.
However, when I run the command: docker, the machine returns with the following message:
bash: docker: command not found
Does anyone know what I am missing in order to make this work per the author's instructions?
I am using Docker v. 1.11.1, on a fresh CentOS 7 box.
Thanks in advance
Figured this out today. The above command will work so long as the docker daemon + dependencies are added to the container. In my case, I ended up writing a simple Dockerfile, which also included the line:
RUN curl -sSL https://get.docker.com/ | sh
This installed Docker on the container, and when I ran docker images from within the container, I could see all of the images from my host machine. I am now able to use all of the docker commands from within the container.
