In this blog, we will share you how to access docker host remotely using docker client.

 

REQUIREMENTS

  • Nano Server with Docker Installed
  • Client Machine to access the docker host through PowerShell

 

DOCKER ENGINE OVERVIEW

 

The docker engine is powered by dockerd in both windows and Linux. Dockerd is for Docker Daemon. This service has an ability to interface with docker client. It has lots of start-up options to customize the docker client service. We can configure the start-up option manually or we can setup in a configuration file. To configure the remote access to docker host, we need to specify the IP and port number using the customize options.

 

For more information about the dockerd, please check this URL: https://docs.docker.com/engine/reference/commandline/dockerd/#windows-configuration-file

 

CONFIGURING FIREWALL

  • We need to open a port a firewall on nano server (docker host). Execute the below command to open port 2375

netsh advfirewall firewall add rule name=”Docker Daemon” dir=in action=allow protocol=TCP localport=2375

INSTALLING DOCKER ENGINE IN CLIENT MACHINE

  • Execute the bunch of PowerShell scripts given below.

Invoke-WebRequest $package -OutFile “$env:TEMP\docker.zip” -UseBasicParsing

Expand-Archive -Path “$env:TEMP\docker.zip” -DestinationPath $env:ProgramFiles

[Environment]::SetEnvironmentVariable(“path”,$env:Path + “;$($env:ProgramFiles)\Docker”, [EnvironmentVariableTarget]::Machine)

 

Above scripts will download the docker.zip and extract the files under program files folder. Also, it adds the environment variable for Docker folder.
