Even in the absence of docker-machine one can still create a remotely accessible Docker Host on a Windows Server 2016 VM.
The steps are very straight forward:
The docker-compose tool is pretty popular for running dockerized applications in a local development environment. All we need to do is write a Compose file containing the configuration for the application's services and have a running Docker engine for deployment. From here, we can get the application running locally in a few seconds with a single `docker-compose up` command. Unit Description=Docker HTTP Socket for the API Socket ListenStream=2375 BindIPv6Only=both Service=docker.service Install WantedBy=sockets.target Register the new systemd http socket and restart docker systemctl enable docker-tcp.socket systemctl stop docker systemctl start docker-tcp.socket.
The Docker Manager communicates with the Docker Engine via TCP. The Docker Engine needs to be configured to open the TCP port, which is usually 2375. If the port is not the default one, then this property needs to be provided in the CPS. Docker Engines CPS Property. It is conventional to use port 2375 for un-encrypted, and port 2376 for encrypted communication with the daemon.
Create the certs on the server using dockertls.If you're creating the certs with an IP address, you may want to consider a static IP to avoid having to recreate certs when the IP address changes.
Restart the docker service
Restart-Service DockerMake port docker's TLS ports 2375 and 2376 available by creating an NSG rule allowing inbound traffic. Note that for secure connections you only need to allow 2376.The portal should show an NSG configuration like this:
Bl40 music sync player driver download for windows. Allow inbound connections through the Windows Firewall.
- Copy the files
ca.pem, 'cert.pem' and 'key.pem' from your user's docker folder on your machine, e.g.c:userschris.dockerto you local machine. For example, you can ctrl-c, ctrl-v the files from an RDP session. - Confirm that you can connect to the remote Docker Host. Run
Troubleshooting
Try connecting without TLS to determine your NSG firewall settings are correct
Connectivity errors typically manifest themselves in errors like:
Allow unencrypted connetions, by adding
to c'programdatadockerconfigdaemon.json and then restart the service.
Connect to the remote host with a command line like:
Cert problems
Accessing the Docker Host with a cert not created for the IP Address or DNS name will result in an error:
Docker Tcp Port 2375
Make sure w.x.y.z is the DNS name for the host's public IP and that either the DNS name matches the cert's Common Name, which was the SERVER_NAME environment variable or one of theIP addresses in the IP_ADDRESSES variable supplied to dockertls
Docker Port 2375

Enable Docker Remote REST API on Docker Host in Ubuntu
Introduction
Docker provides remote REST API which is beneficial if you want to connect to a remote docker host. Few of the functions which you can achieve using Docker REST API over a simple browser are
- Create and Manage Containers
- Get low-level information about a container
- Get Container Logs
- Start/Stop container
- Kill a container
In this tutorial, I will show you
- What didn't worked?
- What really worked.
Things that didn't worked
Over the internet, most of the people have suggested editing DOCKER_OPTS variable.
- I changed DOCKER_OPTS in the/etc/default/docker file but it didn't have any effect
- Then I tried changing DOCKER_OPTS in the file/etc/init/docker.conf but again no success.

What really worked for me to enable docker remote API on docker host
Docker Windows Port 2375
- Navigate to /lib/system/system in your terminal and open docker.service file2vi/lib/systemd/system/docker.service
- Find the line which starts with ExecStart and adds -H=tcp://0.0.0.0:2375 to make it look likeUbuntu Docker Port 2375<div><em>Please note that docker standard TLS port is 2376 and 2375 are the standard unencrypted port. As we have defined 0.0.0.0, which defines an open interface for everyone. Anyone with network access to this port will have full root access on the host. I have restricted the access by creating an access-controlled list in Azure so please follow some similar mechanism to restrict access</em></div>
