Virtual box vagrant do not set /etc/hosts correctly

[rrameshbtech]

I am setting up cluster using /virtualbox/ folder. But it does not set the /etc/hosts/. The output of vagrant up below

    Setting /etc/hosts on nodes...
Uploading hosts.tmp to /tmp/hosts.tmp

Use either of the following to access any NodePort services you create from your browser
replacing "port_number" with the number of your NodePort.

  http://:port_number
  http://:port_number

Though I set it manually and set ssh. after vagrant halt & vagrant up then all the ssh settings were lost.
I am using BRIDGE mode.
Any help appriciated.

Hello @rrameshbtech and others,

I am suffering this issue too. It looks like the the root cause can be in the setup-hosts.sh script:

MY_IP="$(ip route | grep default | grep -Pv '10\.\d+\.\d+\.\d+' | awk '{ print $9 }')"

When setup-hosts.sh is executed, above returns "", not informing the MY_IP var. This value is used in the public-ip script which is invoked by the Vagrantfile to complete the creation of the /etc/hosts file in the VMs

If you still want to use the bridge mode a quick, dirty and temporary workaround can be to setup these IPs manually in the /etc/hosts file, inform the PRIMARY_IP env var and set its value in the /etc/environment file.

Funny thing is that couple of weeks ago this bridge mode was working fine for me, it seems that the setup_dns function was being executed "too early" 😅 when the VM networking (IP, gateway...) is not yet ready 🤔

Good news are that NAT mode works like a charm 🙌, so maybe this could be an option for you.

Hope it helps,

Luis

ps: nevertheless it would be nice if BRIDGE mode would work for me too (as it is the default one). My stack looks like this:

Just waiting a bit so router DHCP resolves IP for VMs worked for me

sleep 30
MY_IP="$(ip route | grep default | grep -Pv '10\.\d+\.\d+\.\d+' | awk '{ print $9 }')"

Thanks! I was facing this same issue. I set it to sleep 5, that seemed to be enough for my machine.

I'm running VirtualBox v7.1.6 and Vagrant v2.4.3 on:

Edition Windows 11 Pro
Version 24H2
Installed on ‎12/‎3/‎2024
OS build 26100.2894

Thank you, that really helped me :)
