The world after February 18th

As you probably discovered, the February 2020 security update had a significant impact on NAV/Business Central Docker Containers. Especially if you were running Process isolation. Most visible problem was the fact that you couldn’t launch 32bit executables in containers after applying the security update. My blog post from February 14th (https://freddysblog.com/2020/02/14/hyperv-isolation-to-the-rescue/) would explain two ways to mitigate the problem:

  1. Run hyperv isolation
  2. Uninstall February update

None of these are perfect solutions. If you are using non-unicode apps (like finsql and C/AL code) then hyperv isolation really doesn’t work very well. It causes destructive character set conversions and you really don’t want to not apply security updates for a longer period in time. Continue reading

Having Demo Data while developing Business Central Apps with Docker

I have always preached that you shouldn’t try to keep your Docker containers running. Containers should be something, which easily can be dismissed and recreated for any developer. One of the frequent questions is then: But what about my demo/development data? Continue reading

Mounting a database from my online environment using SQL Server on the host

This blog post is really a combination between the last two blog posts, https://freddysblog.com/2019/11/04/using-sql-server-on-the-host/ and https://freddysblog.com/2019/11/12/mounting-a-database-backup-from-my-online-environment-inside-a-container/. As stated in the last blog post, you can only use databases of less than 10Gb in size inside the container due to SQL Express. This blog post will explain how to get past that problem.
