Mounting a database backup from my online environment inside a container

Update 2021/2/10: Microsoft stopped creating images for Docker in the summer of 2020. We now publish artifacts, which can be used to spin up containers and BcContainerHelper has replaced NavContainerHelper. This blog post reflects the old way of using NAV/BC on Docker and references NavContainerHelper, which is outdated.

Just recently, a new functionality was enable in the Dynamics 365 Business Central admin center. The ability to request a backup. It didn’t take long before I got the first question from a partner, who asked whether they could run this locally using Docker. This blog post describes how to do just that. Continue reading →

Using SQL Server on the host

This blog post reflects the old way of using NAV/BC on Docker and references NavContainerHelper, which is outdated.

I have had quite a few partners asking me how to connect a NAV / Business Central container to a SQL Server placed on the host. This is the way I started a blog post back in april here: https://freddysblog.com/2019/04/12/placing-the-database-on-the-host/ and elegantly, I avoided to answer the question and instead described how to place the database on the host and use the SQL engine in the container. Of course this doesn’t solve the issue if you have a very large database, which SQL Express doesn’t support.

In this blog post I will try to address the original problem. Continue reading →

I think I have mentioned before, that I strongly recommend partners to use the extension model and create extensions, which can be published, installed and upgraded much easier then code customizations.

Having said that, I know that there are partners out there for who AL code customizations will be the right stepping stone towards adapting an extension model. Continue reading →

Using APIs on containers

Update 2021/2/10: Microsoft stopped creating images for Docker in the summer of 2020. We now publish artifacts, which can be used to spin up containers and BcContainerHelper has replaced NavContainerHelper. This blog post reflects the old way of using NAV/BC on Docker and references NavContainerHelper, which is outdated.

A while ago, I added two functions to the ContainerHelper for using APIs on containers:

  • Get-BCContainerApiCompanyId
  • Invoke-BCContainerApi

In the end, these functions are just invoking a REST method on the container, so why create a function for this? Continue reading →

Zombie containers -> Skip This Build?

Yet Another Update: A cure is found… https://freddysblog.com/2019/09/05/a-cure-for-zombie-containers/

Another Update: Docker engine 19.03.2 (and docker Desktop 2.1.0.2) should be released first week of September with a cure for Zombie containers.

Update: A way to bring your Zombie Container back to live is in the comments by Mick Carr (THANKS MICK) – just tried this and it works on my Computer with 2.1.0.1 as well. Basically modify the containers config.v2.json, change running to false, restart docker and now your container is dead (not living dead). Use docker start to start the container and it comes back to life…

Over the last few days I have experienced a strange behavior with the latest version of Docker Desktop Community edition (2.1.0.0 (36874) released July 31, 2019) on my Windows 10 1903 machine. Thinking this was a problem with my machine, I decided to postpone the investigation, while working on other issues. Yesterday I had two partners contact me with the same behavior, it was going to be a long night… Continue reading →

With the release of NAV and Business Central images on Docker, a lot of people who are not familiar with PowerShell will be using PowerShell. They will be handed a script to run and they will run it. Then something doesn’t work as expected – and somebody (might be me) will tell them to add a parameter called xyz. That might seem simple for people who use PowerShell on a daily basis, but not if you have never written PowerShell before… Continue reading →
