Cannot run docker container in windows server 2019 vmware. It was error response from daemon
docker container run mcr.microsoft.com/windows/nanoserver:1809 hostname
docker: Error response from daemon: container bb81979fe2974f59031e56e062f1b08f1ad6fdaa57ec57965c316563f384da59 encountered an error during hcsshim::System::Start: context deadline exceeded.
Have you tried running it with Hyper-V?
docker run -it --isolation=hyperv mcr.microsoft.com/windows/nanoserver:1809
If it works you can create or edit the config file:
C:\ProgramData\docker\config\daemon.json
Add:
{
"exec-opts": ["isolation=hyperv"]
}
Sure. If you are using something that does not require windows container. You can run a container on linux. I would install an instance of ubuntu or centos on vmware install docker and work with it there.
Download centos
https://docs.centos.org/en-US/centos/install-guide/downloading/
Install docker
https://docs.docker.com/engine/install/centos/
A side not though this is not really production grade orchestration. You may want to look at docker swarm / kubernetes / openshift for prod workloads.
I have docker (docker for windows server) and jenkins both running on a windows server 2019 and I am trying to add Docker Host URI in Jenkins but I ran into timeout error or connection refused error all time and cannot connect to docker host.
I tried the following urls:
tcp://:2375 (or 2376),
tcp://localhost:2375 (or 2376),
tcp://127.0.0.1:2375 (or 2376)
Do I have to configure anything else on docker or jenkins?. I cannot move forward in this issue. it would really help me if any one can provide some guidance to solve this.
I was facing similar issue. You need to expose your docker demon at port 2375. I did it via docker desktop.
Then added HOST URl as tcp://127.0.0.1:2375
I have a docker image that runs a webserver and I would like to access it from my local OSX, but I'm having issues.
I start the container with: docker run -p 8000:8000 <container-name>
and I can see log messages telling me that the local server is listening on localhost:8000
I am able to get a successful response from running:
docker exec <IMAGE-ID> curl "http://localhost:8000/"
Addresses I've tried on my local OSX are:
http://localhost:8000/
http://<DOCKER-IP-172.17.0.2:8000/
Neither of those work. Any suggestions?
Container is built from golang:1.8
Docker Version: Version 17.03.1-ce-mac5 (16048)
MacOS Sierra: 10.12.4
Firewall is turned off for testing purposes
I've tried the same process on Ubuntu 16.04 and no luck their either.
The newer versions of docker use vpnkit on OSX to manage the port forwarding to the containers... you should allow vpnkit through your firewall if you want to expose the container ports.
Also, in your Go code, make sure to bind to 0.0.0.0 rather than 127.0.0.1 for your webserver code.
I'm starting to experiment with Kubernetes on my Windows 10 dev machine. I've got minikube running on my machine, with some "canned" test services, so it looks like Kubernetes is working properly.
Now I'm trying to create my first service by following this: http://kubernetes.io/docs/hellonode/
The problem is I can't build the docker image. I get an error that basically says docker isn't running. I've installed the docker toolkit, and I've looked at docker for windows, but it needs hyper-v which doesn't work with Kubernetes (it requires VirtualBox). So is there any way I can get docker running on windows using VirtualBox?
Once you have the docker client on your host windows machine, you can run
minikube docker-env --shell powershell
That will point the docker client on your host to the docker daemon inside the minikube VM.
I'm runner Docker for OSX, and having trouble getting the Docker remote API to work.
My situation is this:
Docker daemon running natively on OSX (https://www.docker.com/products/docker#/mac, so not the boot2docker variant)
Jenkins running as docker image
No I want to use the Jenkins docker-build-step plugin to build a docker image, but I want it to use the docker daemon on the host machine, so in Jenkins settings, DOCKER_URL should be something like :2375. (Reason for this is I don't want to install docker on the jenkins container if I already have it on my host machine).
Is there a way to to this or is de Docker for Mac currently not supporting this? I tried fiddling with export DOCKER_OPTS or DOCKER_HOST options but still get a Connection refused on calling http://localhost:2375/images/json for example.
Basicly the question is more about enabling the Docker for OSX remote api, with use case calling it from a Jenkins docker container.
You could consider using socat. It solved my problem, which seem to be similar.
socat TCP-LISTEN:2375,reuseaddr,fork UNIX-CONNECT:/var/run/docker.sock &
This allows you to access your macOS host Docker API from a Docker container using: tcp://[host IP address]:2375
On macOS socat can be installed like this:
brew install socat
See here for a long discussion on this topic: Plugin: Docker fails to connect via unix:// on Mac OS X
If you already added an SSH public key to your remote server, then you can use this ssh credentials for your docker connection, too. You don't need to configure the remote api on the server for this approach.
When connecting to macOS Docker Desktop, you could use ssh (after you have enabled it on Mac)
docker -H ssh:user#192.168.64.1 images
or
export DOCKER_HOST=ssh:user#192.168.64.1
docker images
I had the same issue but with mysql. I needed to expose the port of my docker hosts on port 43306 to docker image mysql running on port 3306.
Solution:
Create your docker image with -p parameter.
Example:
#> docker run -p 0.0.0.0:43306:3306 --name mysql-5.7.23xx -e MYSQL_ROOT_PASSWORD=myrootdba -d mysql/mysql-server:5.7.23 --character-set-server=utf8mb4 --collation-server=utf8mb4_unicode_ci
Now I can connect from my host docker server on port 43306 to mysql docker image.
