| ### HOW TO USE | |
| ### Pre-req: | |
| ### - run on a Proxmox 6 server | |
| ### - a dhcp server should be active on vmbr1 | |
| ### | |
| ### - fork the gist and adapt the defaults (especially SSHKEY) as needed | |
| ### - download latest version of the script: | |
| ### curl wget https://gist.githubusercontent.com/chriswayg/43fbea910e024cbe608d7dcb12cb8466/raw/create-cloud-template.sh > /usr/local/bin/create-cloud-template.sh && chmod -v +x /usr/local/bin/create-cloud-template.sh | |
| ### - (optionally) prepare a cloudinit user-config.yml in the working directory | |
| ### this could be copied and modified from the cloudinit user dump at the end of this script | |
| ### - run the script: | |
| ### $ create-cloud-template.sh | |
| ### - clone the finished template from the Proxmox GUI and test | |
| ### | |

Hello, with respect to Flatcar linux and your comments above , I can confirm that the
manage_etc_hostsbug exists. But I can not replicate a successful build withcicustom. Can you share yours? Even things as simple as:hostname: testand
manage_etc_hosts: false hostname: "test" ssh_authorized_keys: - REDACTEDDon't work for me. I am never able to connect after the VM comes up and a VNC console shows that the hostname is set to
localhostnottest.
https://gist.github.com/aw/ce460c2100163c38734a83e09ac0439a
Did you try this method ?
I modified this script a little bit.
Now you can set the used storage for the VM
You can also set the used format for the disk images
The node name is automaticly set since Proxmox uses the systems hostname as nodenames.
I also added a new menu for Ubuntu which will let you choose the version between 18.04 and 20.04.

Hello,
I use this script on debian 9.But the nameserver always use 127.0.0.1
How to fix it?
Hello,
Could support Centos8 and Ubuntu 20.04 LTS?
please see my updated one with centos8 more ubuntu ones and also almalinux
https://gist.github.com/meramsey/aa759614cb5e387d8b88a0adfe77cc1d
Also there is alot of improvements that could be made to this such as enabling root login and adding in custom packages and naming the containers nicer. You really don't need to usually expand the disk until its deployed and if you use cloud-init then it will expand on first boot so there is no reason to normally make the template large in advance of when its used unless you got space to burn.
Also for more detail see:

I need to make a script wrapper for this but you can get an idea of how easy it is with the below examples:

Heya,
Thank you very much for this!
I've made some changes so that passwords and VLANs can be added if needs be:
Albeit, this is purely for Ubuntu, but should be easily scalable to others.
How can I put multiple routes?

# Create/Set vNIC
qm set $VMID --net0 virtio,bridge=${NET_BRIDGE}${VLAN:+,tag=$VLAN}
qm set $VMID --net1 virtio,bridge=${NET_BRIDGE}${VLAN:+,tag=$VLAN}
# Create/Set Cloud-Init vNIC settings
qm set $VMID --ipconfig0 ip=10.10.10.222/24,gw=10.10.10.1
qm set $VMID --ipconfig1 ip=10.10.0.222/24,gw=10.10.0.1The above has variables that are set in my script in the above comment, but they should be easy enough to figure out.
Thank you,
sorry, I am not very familiar with scripts.
But to create several routes with the same network interface and being in the same VLAN?
--ipconfig0 and --ipconfig1 have nothing to do with the interface or yes?
I can easily make several lines for each route leaving only net0?
qm set $VMID --ipconfig0 ip=10.10.10.222/24,gw=10.10.10.1
qm set $VMID --ipconfig1 ip=10.10.0.222/24,gw=10.10.0.1

netX is the interface details (you might need to add a vlan tag as well).
qm set 100 --net0 virtio,bridge=vmbr1,tag=10
qm set 100 --net1 virtio,bridge=vmbr1,tag=20
ipconfigX is to configure the interface in cloud-init if you're using that.
qm set 100 --ipconfig0 ip=10.10.10.222/24,gw=10.10.10.1
qm set 100 --ipconfig1 ip=10.10.0.222/24,gw=10.10.0.1
You cannot define an IP address in the NIC settings in the hardware tab as IP addresses are dealt with by the VM. But you can set VLAN tags.
What you can do, if you use cloud-init is define what the IP address/subnet should be - although this is optional, but very useful.

Hello, with respect to Flatcar linux and your comments above , I can confirm that the
manage_etc_hostsbug exists. But I can not replicate a successful build withcicustom. Can you share yours? Even things as simple as:hostname: testand
Don't work for me. I am never able to connect after the VM comes up and a VNC console shows that the hostname is set to
localhostnottest.
