Remove All Docker Container Images

New Windows Server 2019 Container Images

Microsoft today released the new Windows Server 2019 again. After they quickly released Windows Server 2019 during Microsoft Ignite, they removed the builds again, after some quality issues. However, today Microsoft made the Windows Server 2019 builds available again. Microsoft also released new Windows Server 2019 Container Images for Windows, Windows Server Core and Nano Server.

Download Windows Server 2019 Container Images

You can get them from the new Microsoft Container Registry (MCR).

Microsoft was hosting their container images on Docker Hub until they switch to MCR (Microsoft Container Registry). This is now the source for all Windows Container Images like Windows Server 2019, Windows Server 2016 and all the Semi-Annual Channel releases like Windows Server, version 1709 or Windows Server, version 1803.

Download the Windows Server 2019 Semi-Annual Channel Container Images (Windows Server, version 1809). This includes also the new Windows Container Image.

The Windows Server Core Image is also available as a Long-Term Servicing Channel Image:

However, if you want to browse through container images, Docker Hub continues to be the right place to discover container images. Steve Lasker wrote a blog post about how Microsoft syndicates the container catalog and why.

Also the existing Windows Server 2016 and Windows Server, version 1803 and Windows Server 1709 container images moved to the Microsoft Container Registry (MCR).

You should also make sure to update your Dockerfile references:

Old Windows Server Dockerfile reference

FROM microsoft/windowsservercore:ltsc2016

New Windows Server Dockerfile reference

FROM mcr.microsoft.com/windows/servercore:ltsc2016

Removing the “latest” tag from Windows Images

Starting 2019, Microsoft is also deprecating the “latest” tag for their container images.

We strongly encourage you to instead declare the specific container tag you’d like to run in production. The ‘latest’ tag is the opposite of specific; it doesn’t tell the user anything about what version the container actually is apart from the image name. You can read more about version compatibility and selecting the appropriate tag on our container docs.

Next to me there will be a lot of great community speakers present. Geekmania is always a lot of fun, so hopefully see you there!



Thomas Maurer speaking at Experts Live Europe

Azure Stack Operations Interview at Experts Live Europe

As you may know I was speaking at Experts Live Europe 2018 in Prague a couple of days ago, which was a lot of fun. In my sessions, I was talking about Azure Stack Operations and Windows Server 2019. Between does sessions I had time to quickly talk about Azure Stack Operations and Experts Live Europe in a short interview.

I really enjoyed the conference and hopefully I will be back next year. If you want to see more videos from Experts Live Europe 2018, check out the Experts Live TV YouTube channel. Thanks to the Experts Live team for the great conference and the great opportunity to speak there.



HPE Azure Stack Innovation Center

Let’s talk about the HPE Azure Stack Innovation Center

Together with HPE, I did some short videos about HPE Azure Stack and the HPE Azure Stack Innovation Center in Geneva. The videos are very short to just give you a quick idea about the different scenarios and the benefits of the Innovation Center as well as the HPE solutions. If you want to know more about it, you can check out my blog and look for my articles on Azure Stack and Azure.

About the Azure Stack Innovation Centers

To help you get started on your journey with Microsoft Azure Stack, HPE and Microsoft have built Azure Stack Innovation Centers. Staffed by HPE and Microsoft experts, and leveraging the latest industry-leading Azure Stack hardware and software solutions, the Azure Stack Innovation Centers are designed to help simplify and accelerate your hybrid cloud journey.

In simple words, the Innovation Centers are a place to try out Azure Stack multi-node systems, do proof of concepts and test your real-world workloads. We used the Azure Stack Innovations Centers to work with customers, to try out their workloads directly on a full multi-node system. This helps to better understand the benefits and challenges for the specific customer workloads and get some hands-on experience. It is also a great possibility to test out the Azure Stack Operator capabilities and tasks.

Azure Confidential Compute VM Deployment

Protect Workloads with Azure Confidential Computing

A year ago Microsoft announced that they were working on a new technology in Azure to protect and encrypt data in use, called Azure Confidential Computing. If you are moving sensitive data to the cloud, you also want to encrypt it. Today, you can do this for data in transit and data at rest, however data in use is a challenge. Azure Confidential Computing addresses exactly that scenario, and helps you to encrypt data in use. Microsoft was running a private preview program in the last year, and at Microsoft Ignite this year, Microsoft opened up a public preview.

What is Azure Confidential Computing

Azure Confidential Computing together with Intel SGX technology addresses the following threads:

  • Malicious insiders with administrative privilege or direct access to hardware on which it is being processed
  • Hackers and malware that exploit bugs in the operating system, application, or hypervisor
  • Third parties accessing it without their consent

There are ways to secure data at rest and in transit, but you need to protect your data from threats as it’s being processed. Now you can. Confidential computing adds new data security capabilities using trusted execution environments (TEEs) or encryption mechanisms to protect your data while in use. TEEs are hardware or software implementations that safeguard data being processed from access outside the TEE. The hardware provides a protected container by securing a portion of the processor and memory. Only authorized code is permitted to run and to access data, so code and data are protected against viewing and modification from outside of TEE.



Create new Azure Backup

Backup Windows 10 to Microsoft Azure Backup

This is not really a new feature, it exists already for a while, but it seems that still a lot of people don’t know about it. Azure Backup not only allows you to backup services in Azure or Windows Server and services on-premises, Azure Backup can also backup your Windows Client PC.

Azure Backup for your Windows 10 PC allows you to backup Files and Folders and store and backup them to the cloud. You can use this for small environments, VIP machines or for remote workers which are always on the road. Data is encrypted on the on-premises client machine using AES256 and the data is sent over a secure HTTPS link. Backups are stored encrypted in Azure with the customers own key.

I use Azure Backup for my own devices. I am often on the road and working on different documents and files. Obviously I also use OneDrive and OneDrive for Business, which also allows you to restore files after you delete them. However, the retention rate is way to short and it is not a backup. Azure Backup in that case is a great addition. You can backup your files where ever you are.

Setup Azure Backup for Windows Clients

Azure Backup and Site Recovery

First you will need to setup a Azure Recovery Services Vault in Microsoft Azure. This is the service which your backups will be stored.



Microsoft Certified Azure Administrator Associate

Passed Microsoft Certified: Azure Administrator

After the announcement of the new Microsoft Azure certifications at Microsoft Inspire in Las Vegas, I decided to take the beta exam which was available to upgrade my current Azure certifications. Since I had already passed Exam 70-533 Implementing Microsoft Azure Infrastructure Solutions, I needed exam AZ-102 to do the transition. Today I got confirmation that I passed the Microsoft exam AZ-102 and earned the Microsoft Certified Azure Administrator Associate certification.

I already took the new available beta Exam for the Microsoft Certified Azure Architect at Microsoft Ignite, however for the results I still need to wait a bit.

What is Exam AZ-102 Microsoft Certified: Azure Administrator Associate

The new certifications are based on different job roles, like Azure Administrator, Azure Developer and Azure Architect. You can read more about the new Azure Certifications here on my blog.

Earning Azure Administrator Associate certification demonstrates understanding of services across the IT lifecycle, and ability to take requests for infrastructure services, applications, and environments. Candidates for this certification are typically Azure Administrators who manage cloud services spanning storage, security, networking, and compute cloud capabilities. They recommend services to use for optimal performance and scale, as well as provision, size, monitor, and adjust resources.

This is great news to start in the day while I am flying to a customer in Paris today for some more Azure work.

Exam Preparation

The skills measured in AZ-102 are a mix from AZ-100 and AZ-101 and will focus on Azure Infrastructure and deployment, Azure Integration and Azure Security.

I often get asked how I prepared for exams such as this. Obviously it makes sense to certify the knowledge you already have. I usually use Microsoft free online courses on Channel 9, Virtual Academy and now the new Microsoft Learn. However, I realized that also the Azure Documentation is a great resource to learn. I recommend you check the skills needed for the exam, in this case AZ-102 and read the specific Azure Documentation for these topics, and also try it out.
