Centos as Host OS #1

Closed funky81 closed 5 years ago

Hi, thanks for the guide and code for this. Just wondering, if I'm using centos, which part that I should change to make it compatible with centos

Thanks

Hi,

You should modify the first parameter of the Kubespray configuration template to "centos" instead of "ubuntu": https://github.com/sguyennet/terraform-vsphere-kubespray/blob/master/templates/kubespray_all.tpl

The second thing is that will be different is the VM template itself. Be careful because I believe that CentOS doesn't install the open-vm-tools automatically. You will have to install them during the creation of the VM template. The open-vm-tools are used by Terraform to customize the VM (network configuration, etc.). Without them inside the template the Terraform deployment will fail.

Let me know if you have an issue. I never tested it myself but I can do a quick lab around this if needed (it is not the first time someone ask me about CentOS :D ).

Have a good weekend,

Simon.

Thanks for your feedback..

noted for this, i have successfuly change

Noted also, the VM already successfully installed the VMware-Tools.

Last thing is that there's script when installing HAproxy server, and i've got

sudo: apt-get: command not found

Since I'm using Centos, have to change this into yum. Feedback very welcome

Thanks

Hi, now I have change the apropriate file, to change apt-get command into yum. but now I got error like in below

Using /root/terraform-vsphere-kubespray/kubespray/ansible.cfg as config file ERROR! no action detected in task. This often indicates a misspelled module name, or incorrect module path. The error appears to have been in '/root/terraform-vsphere-kubespray/kubespray/roles/vault/handlers/main.yml': line 44, column 3, but may be elsewhere in the file depending on the exact syntax problem. The offending line appears to be:

  • name: unseal vault ^ here

Any solutions for this?

Thanks

funky81 commented 5 years ago

Done, i already found out the solution

sguyennet commented 5 years ago

Good to know you managed to have it working on CentOS. I forgot about the HAProxy configuration which is done as an inline in the Terraform script. I should probably modify this as it is not very clean.

funky81 commented 5 years ago

Yup, thanks ...already use this script. Working flawlessly. Thanks
