NavContainerHelper doesn’t work anymore…

With a total of over 300000 downloads, NavContainerHelper is no more. As of this weekend, NavContainerHelper cannot be used to create containers anymore. There has been a lot of blog posts here on my blog and others that indicated that this day would come and now it is here… – all specific images are gone and with those all the “old” generic images, which was used by NavContainerHelper.

I will contact PowerShell Gallery to get the entry removed.

RIP NavContainerHelper, Long Live BcContainerHelper.

Removing all specific NAV and Business Central Docker Images

On October 27th 2017, I posted the first announcement which introduced NAV on Docker. For approx. 3 years we published Docker images first to Docker Hub and later to Microsoft Container Registry for both Windows Server 2016 and Windows Server 2019. Many 1000 images was pushed to the container registries until we during the summer of 2020 changed strategy to use artifacts together with the generic image.

The various versions of specific images on different container OS’ amounts to more than 100Tb of docker images and now is the time to cleanup…

How to use Run-AlValidation

When releasing the first version of Run-AlValidation in BcContainerHelper, i did a quick blog post about the function here. This blog post serves to explain some common scenarios of how to run the function. The blog post will also explain the parameters of Run-AlValidation a bit more in depth, for people to have a good chance of using the function before submitting for AppSource Validation.

TimeStampServer – you had one job!

The important part of this blog post: Please make sure to upgrade to BcContainerHelper 1.0.18 or reconfigfure the timestampServer in your existing version.

December 30th 2020 we got a number of apps for validation failing due to a wrong timestamp signature. Some partners discovered this before submitting and filed an issue on github here, complaining about this error: “The timestamp signature and/or certificate could not be verified or is malformed.

I was enjoying a nice walk in the forest with my dogs, but my phone would reveal increased activity on github and emails from partners running into this strange issue.

18 hours of no containerhelper…

Friday morning around 6am. I had just kicked off a few validation builds when they started failing. Failing builds can happen and typically there is a valid reason for this, but in this case – ALL builds was failing and looking in the logs I quickly realized that this problem was something different.

PowerShell Gallery was down, PowerShell Gallery had an outage and it took a stunning 18 hours before it was back online…:-(

Troubleshooting Business Central on Docker

This blog post is not really a troubleshooting guide (although there is a small TSG at the end). It is more like a brain dump of what I have seen over time and how I would approach a trouble shooting session. I have divided it into 6 sections:

  1. Dockers worst enemy (just FYI)
  2. Installing Docker
  3. Installing BcContainerHelper
  4. Creating a Business Central container
  5. Keep the script, not the Container
  6. Frequently seen docker errors

Going forward, I will add a link to this blog post to all issues on https://www.github.com/microsoft/navcontainerhelper/issues, where the answer to the issue is in this blog post.

Run-AlPipeline

WARNING: Very boring long blog post ahead…

Run-AlPipeline is a new function in BcContainerHelper. It has been in preview for a number of releases while being worked on, and a number of partners have already tried to use it. My apologies for changing things under your feet, but to my defense – I did write that the function was in preview.

With version 1.0.8 of BcContainerHelper, Run-AlPipeline is ready for real-life usage… (I think)

One of these days…

Many years ago, I heard a joke:

3 people (a biologist, a mathematician and a developer) were in Africa on a Safari. They drive by a blue elephant. The biologist shouts out: “Look, there is a BLUE elephant.”. The mathematician states: “Right you are, there is ONE blue elephant”. The developer slaps his palm against his forehead and says: “Damn, there are blue elephants…
