I am trying to connect my Windows 10 Home system to be able to run full Linux OS Docker containers. I have installed Docker on both WSL Ubuntu 18.04 as well as a VMware Ubuntu 18.04.
I was trying to follow this guide.
However, I get stuck trying to configure the Daemon as per the instructions.
Can’t use Docker for Windows?
This is only necessary if you are NOT running Docker for Windows!
No problem, just configure your Docker daemon to use -H tcp://0.0.0.0:2375 and --tlsverify=false. Then you can follow along with the rest of this guide exactly.
If you go down this route, I highly recommend rolling your own VM with VMware Player instead of using the Docker Toolbox because VirtualBox has crazy edge case shared folder bugs that will ruin your life at some point. Don’t worry, VMware Player is free. Just Google how to set up Ubuntu 16 server on VMware Player.
When I try to change the Docker Daemon by making a daemon.json file I get errors. I've also tried editing the .profile files and the .bashrc as per other guides (another guide), with no luck.
I am unable to check the DOCKER_HOST variable on the VM Ubuntu.
Don't make things complicated. In your case, why WSL if you just want to connect to a remote daemon? Why not simply use the windows docker client?
Setup you favorite local VM with docker.
Example: I have installed a CentOS distro running on local VMWare Workstation. All Hyper-V of course deinstalled/deactivated.
In this VM, enable tcp access for the daemon.
If you have a systemd linux distro (like mine CentOS), execute this:
sudo mkdir -p /etc/systemd/system/docker.service.d
sudo echo '[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H unix:// -H tcp://0.0.0.0:2375' >> /etc/systemd/system/docker.service.d/options.conf
sudo systemctl daemon-reload
sudo systemctl restart docker`
Test if the port is open with docker info. You should get an API access warning at the bottom result.
Download the Windows docker cli zip from here: https://download.docker.com/win/static/stable/x86_64/
Move the docker.exe to any folder, for ex. your Documents folder.
Then put this folder path into your Windows PATH variable.
Set the docker host: Open PowerShell, execute setx DOCKER_HOST <VM-IP>:2375 and close it.
Open a new PowerShell and call docker info.
You should see the docker and daemon infos.
Do what ever you like now... :-)

Has anyone succeeded in running fabric-composer on windows 10 linux sub-system running ubuntu 16.04 ?
You can run composer on windows 10 WSL (windows Subsystem for linux) but you will not be able to run docker containers in it. Linux Docker containers require a linux kernel and WSL doesn't have a linux kernel. It is a clever piece of technology that converts user space Linux API calls dynamically to windows API calls.
Therefore you will have to run hyperledger fabric either by using docker for windows (which runs it for you in hyper-v) or you run your own hypervisor.
It is possible to have the docker commands run in WSL but it will need to configure it to interact with the docker daemon running inside a hypervisor.
Yes, you can use Hyperledger-fabric-composer on windows 10, but as david said in above answer you will not be able to run docker containers directly from Ubuntu sub-system.
To do that you have to do following things:
METHOD:- 1
You will need to install docker CE Client & docker-compose in Ubuntu Subsystem and install Docker(version v17.09) on Windows as well. But those dockers won’t connect together out of the box.
So you need to expose the daemon to port 2375 first by right-clicking the docker icon on task-bar then click setting then check the Expose daemon box.
Now the docker server will be able to connect via Windows network including Ubuntu subsystem. We need to set environment variables in Ubuntu by running below command:
echo "export DOCKER_HOST='tcp://0.0.0.0:2375'" >> ~/.bashrc
source ~/.bashrc
These commands will add DOCKER_HOST to the variables every time we start a new Bash.
METHOD:- 2
If you don't want to use ubuntu sub-system, then you can simply install Git Bash and Docker(version v17.09).
Then install Hyperledger-Fabric by using Git Bash.
I'm using Windows 7 Pro and have existing shared Docker engine running on a Linux. I would like to use my workstation (with development environment) to access shared Docker engine.
Does someone know how to retrieve Docker client only for Windows 7 ? I have no admin privilege, so I can't install Docker Toolbox.
Older Clients can be found here https://download.docker.com/win/static/stable/x86_64/
And here a some newer Builds by Stefan Scherer (Docker employee) https://github.com/StefanScherer/docker-cli-builder.
Just download docker.exe and add it to your windows path variable.
Then set your DOCKER_HOST variable to define against which Docker daemon you want to speak.
The official Downloads have finally been published:
Mac CLI binaries are available at
https://download.docker.com/mac/static/stable/
Windows CLI (and daemon) binaries at https://download.docker.com/win/
Linux CLI packages are available for each distro as docker-cli (deb and rpm) packages: https://download.docker.com/linux/ubuntu/dists/focal/pool/stable/amd64/

Although docker provides a REST-like API, there aren't many clients for it. A quick google turned up one on github, but ymmv. Even if you did find one, you're likely to run into the same problems involved in running docker-ce locally anyway.
There are a handful of gui clients that you could run on that engine and access with a browser, but if you are specifically after a cli you're SOL with this.
If you have an ssh client (git bash, or putty, or something), and you can arrange to run a bastion container on the engine, then you could run a container to ssh into and use that as if it's your local machine. You'd still have to scp resources onto it, but you'll eventually have to solve that problem anyway. Something like:
sudo docker container run --interactive --tty -v /var/run/docker.sock:/var/run/docker.sock image
Where 'image' is a linux image with an ssh server and appropriate keys, git, and docker installed. You could mount a local volume for persistence, or you could just keep everything in git.
I installed the latest stable docker for Mac, and started the docker directly without a virtual box. I know that it must have started a virtual box, so I use "docker-machine ls" to find the default machine, but it list nothing. How can i find the virtual machine? My OS version is 10.10.5
PS:
In fact, I didn't create any virtual machines, but do run my spring-boot app on the "alpine-oraclejdk8" image, so does that mean I exactly using the docker? And the reason I want to find the virtual machine is I used "nsenter" to enter the container to debug the log of my app but it doesn't work(the writer of "nsenter" told that I need enter the virtual machine first). So this is my confusing point that how the docker is running but I cant find the virtual machine on MAC
Docker for mac does not use docker-machine. The app that runs and give you the little whale icon in the top menu bar runs its own virtual machine. This virtual machine uses hyperkit, which is a project that uses xhyve, which is a port of bhyve to the mac os darwin kernel.
This will not create any entries to make docker-machine aware of the vm.
Rather than using nsenter to enter your container, you should use the docker exec command instead. The advantage of using docker exec is that it works without having the first ssh to where docker is running.
Because you need to create it.
Run the command
docker-machine create vm1
And you'll have your machine.
To redirect your docker client to the specific machine use this command
eval $(docker-machine env vm1)
Where 'vm1' is the same 'vm1' name that you used to create the machine. You can have a number of docker machine running at the same time using various backends like virtualbox or aws
I just install the Windows 10 Anniversary update which has a new feature that linux child system. So I try to run docker in Windows 10 ubuntu bash(linux child system). Why I want to install docker in linux child system is because:
Windows 10 native docker 1.12 need Hyper-V, but Vmware couldn't run if Hyper-V enable. I have a lot images created by Vmware, it isn't so easy to switch to Hyper-v
I don't want to use Docker Toolbox, it need install VirtualBox, just redunant.
apt-get is fine, docker install success, but fail to start.
$ sudo service docker start
initctl: Unable to connect to Upstart: Failed to connect to socket /com/ubuntu/upstart: Connection refused
* Starting Docker: docker [ OK ]
$ docker ps
Cannot connect to the Docker daemon. Is the docker daemon running on this host?
I have seen this post can-you-run-docker-natively-on-the-new-windows-10-ubuntu-bash-userspace, some people says that it is no posible to run docker in such linux child system, but there also some contrary opinions.
So, I want to ask is there any way to walk around this? Or I have to wait MS update this child system(since it is still beta now).
You have two Problems in there:
the linux child system does not provide the upstart service like e.g. ubuntu. You can work around this by running the docker deamon directly in foreground with docker daemon ...
This does nearly shure not work because docker requires features of the linux kernel like namespaces and capabilities. I don't think the NT-Kernel does implement such exotic features.
I'm new to Docker...
From my understanding, Docker is only compatible with Linux, is it possible to run docker for development purposes on a Mac?
I installed virtualbox using homebrew and have tried to create a virtualbox instance. I installed docker, but am having trouble getting my mac to communicate with the vm docker instance. My end goal is to get a locally debuggable instance of tomcat running on the docker container.
Any help or tips would be helpful.
Information:
Because Docker only runs on Linux you will need to install some kind of virtual instance on your local machine. An easy and popular way to do that is to install
Boot2docker and VirtualBox. VirtualBox is a dependency of Boot2docker. You can download, setup and install the latest versions from their websites or if you are using Homebrew, as you mentioned, you can quickly get the working binaries both in one step.
After installing boot2docker, you're ready to use Boot2docker to create a Tomcat Container. You can find a pre-configured tomcat image by searching Docker's community repository, docker hub registry.
Notes:
Each time you execute the docker run command a new container is created.
The VM running Docker requires a ssh private/public encryption key handshake to connect to. If you follow my steps below, one will be generated for you.
Steps to Setup Tomcat using the tomcat image:
Open Terminal and run this command: brew install boot2docker
Create a new Boot2Docker VM instance using the init command: boot2docker init
Run this command in Terminal to forward local ports to the vm:
for i in {10000..10999}; do VBoxManage modifyvm "boot2docker-vm" --natpf1 "tcp-port$i,tcp,,$i,,$i”; VBoxManage modifyvm "boot2docker-vm" --natpf1 "udp-port$i,udp,,$i,,$i";done
Start the boot2docker daemon: boot2docker start or boot2docker up
After starting docker, copy the exports that are displayed from the previous command to your clipboard
Edit your bash profile file ~/.bash_profile (or if you are using zsh, edit the resource configuration file ~/.zshrc) with a text editor (I prefer using Sublime text): subl .zshrc *note: this will permanently save the docker env variables.
Paste the exports into that file and save
Execute the source command on the file: source .zshrc
Pull the latest tomcat image to create a container and start tomcat: docker run -it --rm -p 10080:8080 tomcat:8.0 *note: this will forward your local 10080 port to the vm's 8080 port.
Go to http://localhost:10080, you should see the tomcat start page!
Useful Docker commands:
$ boot2docker status
$ docker version
$ docker ps #shows running containers
$ docker ps -a # shows all containers
$ docker exec -it NAME /bin/bash #to start a bash session on the container. -i = interactive, -t = tty

Most people use boot2docker to run on Macs. You may also want to take a look at Kitematic, which gives you a GUI to play with.
Finally, the future is probably to use docker machine, which can provision a VM for you.
Docker requires Linux Kernel features, hence it cannot be run natively on OSX.
See instead Boot2Docker. This link gives you instructions on how to get going.
