In this article, I’ll show you how I build a Docker Container that will connect to Exchange Online.
Following the success of my Office 365 PowerShell container Image, I’ve decided to build another Docker Image that will connect to Exchange Online.
When managing multiple Exchange Online environments, It’s always a bit hard to manage connection sessions when using a management machine and sometimes you can make changes in the wrong environment.
This Image will remove this risk and make the connection process more secure and safe when managing multiple environments or a single environment.
About the build
The Image Is based on Windows Server Core 2016 operating system with the PowerShell connection script that asks for a username and password.
Below, you can see the connection script to Exchange Online, The script Is located on the C:\ Drive.
$powerUser = read-host "Enter Username" $password = read-host "Enter Password" -AsSecureString $adminCredential = New-Object -TypeName System.Management.Automation.PSCredential -argumentlist $powerUser,$password $O365Cred = $adminCredential $ExchangeSession = New-PSSession -ConfigurationName Microsoft.Exchange -ConnectionUri "https://outlook.office365.com/powershell-liveid/" -Credential $O365Cred -Authentication "Basic" -AllowRedirection Import-PSSession $ExchangeSession
And below, you can see the DockerFile that makes all the magic.
FROM microsoft/windowsservercore RUN powershell.exe COPY Connect.ps1 c:\
Once the Image Is completed, I’ll spin a new Container.
docker run -it --rm ntweekly/exchangeonline powershell
To run the Connection script, I’ll start the connection script from the C: drive.
The connection script Is called Connect.ps1
If you want to download the image, please use the command below to pull it from Docker Hub
Docker pull ntweekly/exchangeonline
