### Steps for creating an Ubuntu 18.04 cloud template
|
|
* Using a ready-to-use Ubuntu image
|
|
* [Ubuntu 18.04 LTS (Bionic Beaver) Daily Build](https://cloud-images.ubuntu.com/bionic/current/)
|
|
|
|
```sh
|
|
wget https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img
|
|
|
|
# Create a VM
|
|
qm create 9000 --name ubuntu1804-templ --memory 2048 --net0 virtio,bridge=vmbr1
|
|
|
|
# Import the disk in qcow2 format (as unused disk)
|
|
qm importdisk 9000 bionic-server-cloudimg-amd64.img local -format qcow2
|
|
|
|
# Attach the disk to the vm using VirtIO SCSI
|
|
qm set 9000 --scsihw virtio-scsi-pci --scsi0 /var/lib/vz/images/9000/vm-9000-disk-0.qcow2
|
|
|
|
# Important settings
|
|
qm set 9000 --ide2 local:cloudinit --boot c --bootdisk scsi0 --serial0 socket --vga serial0
|
|
|
|
# The initial disk is only 2GB, thus we make it larger
|
|
qm resize 9000 scsi0 +30G
|
|
|
|
# Using a dhcp server on vmbr1 or use static IP
|
|
qm set 9000 --ipconfig0 ip=dhcp
|
|
#qm set 9000 --ipconfig0 ip=10.10.10.222/24,gw=10.10.10.1
|
|
|
|
# user authentication for 'ubuntu' user (optional password)
|
|
qm set 9000 --sshkey ~/.ssh/id_rsa.pub
|
|
#qm set 9000 --cipassword AweSomePassword
|
|
|
|
# check the cloud-init config
|
|
qm cloudinit dump 9000 user
|
|
|
|
# create tempalte and a linked clone
|
|
qm template 9000
|
|
qm clone 9000 190 --name ubuntu1804-1
|
|
qm start 190
|
|
|
|
rm -v bionic-server-cloudimg-amd64.img
|
|
```
|
|
|
|
* Login with: `ssh ubuntu@10.10.10.190`

### Steps for creating a Debian 10 cloud template
|
|
* Using a ready-to-use Debian image
|
|
* [Debian Official Cloud Images for OpenStack](https://cdimage.debian.org/cdimage/openstack/)
|
|
|
|
```
|
|
wget https://cdimage.debian.org/cdimage/openstack/current/debian-10.0.2-20190721-openstack-amd64.qcow2
|
|
|
|
# Create a VM
|
|
qm create 9110 --name debian10-cloud --memory 2048 --net0 virtio,bridge=vmbr1
|
|
|
|
# Import the disk in qcow2 format (as unused disk)
|
|
qm importdisk 9110 debian-10.0.2-20190721-openstack-amd64.qcow2 local -format qcow2
|
|
|
|
# Attach the disk to the vm using VirtIO SCSI
|
|
qm set 9110 --scsihw virtio-scsi-pci --scsi0 /var/lib/vz/images/9110/vm-9110-disk-0.qcow2
|
|
|
|
# Important settings
|
|
qm set 9110 --ide2 local:cloudinit --boot c --bootdisk scsi0 --serial0 socket --vga serial0
|
|
|
|
# The initial disk is only 2GB, thus we make it larger
|
|
qm resize 9110 scsi0 +30G
|
|
|
|
# Using a dhcp server on vmbr1 or use static IP
|
|
qm set 9110 --ipconfig0 ip=dhcp
|
|
#qm set 9110 --ipconfig0 ip=10.10.10.222/24,gw=10.10.10.1
|
|
|
|
# user authentication for 'debian' user (optional password)
|
|
qm set 9110 --sshkey ~/.ssh/id_rsa.pub
|
|
#qm set 9110 --cipassword AweSomePassword
|
|
|
|
# check the cloud-init config
|
|
qm cloudinit dump 9110 user
|
|
|
|
# create tempalte and a linked clone
|
|
qm template 9110
|
|
qm clone 9110 191 --name debian10-1
|
|
qm start 191
|
|
|
|
rm -v debian-10.0.2-20190721-openstack-amd64.qcow2
|
|
```
|
|
|
|
* Login with: `ssh debian@10.10.10.191`
|
|
|
|
#### To resize the VM disk later
|
|
```
|
|
qm shutdown 190 && qm wait
|
|
qm resize 190 scsi0 +8G
|
|
qm start 190
|
|
```
|
|
|
|
### To fully disable cloud-init
|
|
When booting under *systemd*, you can disable cloud-init completely by either:
|
|
* creating a file: `sudo touch /etc/cloud/cloud-init.disabled`
|
|
* or adding `cloud-init=disabled` to the kernel command line as found in `/proc/cmdline`
|
|
|
|
### To partially disable cloud-init
|
|
To partially disable some functions, modify: `/etc/cloud/cloud.cfg`, for example to disable network configuration:
|
|
```sh
|
|
sudo su -
|
|
echo "network: {config: disabled}" > /etc/cloud/cloud.cfg.d/99-disable-network-config.cfg
|
|
```
|
|
|
|
### To show the Grub Menu on the serial console
|
|
`sudo nano /etc/default/grub config`
|
|
|
|
```
|
|
GRUB_TERMINAL="console serial"
|
|
```
|
|
|
|
`sudo update-grub`
|
|
|
|
