Improvements to the Traefik usage with NAV/BC or why Open Source is awesome

I had introduced the usage of Traefik with NAV/BC containers and also shared the integration into navcontainerhelper over the last couple of months. As always, there was room for improvement and to my delight Damien Duportal, Developer Advocate at Containous, the company behind Traefik, contacted me via email to suggest three important changes:

• I had used the [web] directive in the Traefik config file to make the Traefik dashboard and API available on port 8080. That directive however is deprecated and Damien suggested to replace it with [api] as you can see here
• Having the API open for everyone has a security impact (see CVE-2018-15598 and CVE-2019-12452), so he changed the port binding of the Docker container so that the API is only available from the Docker host VM itself, not from the outside, as you can see here
• And last but not least, something I really should have done to begin with¹: He referenced the Traefik image with a version tag as you can see here

Overall, while maybe not having a huge impact for most users, those are very good improvements. And all of this is only possible because Microsoft (i.e. Freddy) is sharing all this as Open Source on Github. Otherwise I wouldn’t have been able to implement the Traefik support and definitely Damien would never have come across it and improved it. That’s why Open Source rocks!

   I’ve created a PR to the navcontainerhelper for using a custom toml with a certificate:

3. It’s my opinion that a property foreclosure can have a important effect on the applicant’s life. House foreclosures can have a Seven to decade negative affect on a borrower’s credit report. A borrower having applied for a home loan or any loans as an example, knows that a worse credit rating is, the more hard it is to acquire a decent bank loan. In addition, it could affect the borrower’s power to find a respectable place to let or hire, if that will become the alternative property solution. Great blog post.
