Problems when deploying via ansible

[ykorzikowski]

Describe the problem I created a ansible role for deploying netbird automatically.

For this, I retrieve the setup key via bitwarden vault, install netbird and run the up command afterwards. (Will add this to github later)

There are two issues I am dealing with right now:

1. sometimes, the up command fails (actually most of the times). Not sure if its timing issue or something. I am trying to retry it multiple times or restarting the netbird service

2. When re-installing my server via ansible role, connecting a second time to netbird will result into different dns name. E.g. server.example.com will be server-1.example.com after running it a second time. Question: Is there an option for delelting it automatically? Now, I need to manually delete the old netbird entry in the webinterface.

Are there plans improving automatic netbird deployment for servers?

@ykorzikowski I checked your error message and I see this issue already has been solved. More info: https://github.com/netbirdio/netbird/issues/764 In the next release the fix will be available.

[mlsmaycon]

@ykorzikowski the latest v0.14.6 contains the fix for the issue, can you validate?

[ykorzikowski]

Hey @mlsmaycon ,
