# pve-go

PVE-Go is a go library for the Proxmox VE API.

The design is based on the Hetzner Clound API implementation: https://github.com/hetznercloud/hcloud-go

## Cloud-Init Image

How to prepare a cloud-init image.

### Ubuntu 20.04

Download the latest version of the base image to one of your proxmox nodes:

```
curl -sSL https://cloud-images.ubuntu.com/focal/current/focal-server-cloudimg-amd64.img >/tmp/focal-server-cloudimg-amd64.img
```

Create a cloud-init config to bootstrap the template:
```
cat <<'EOF'> /var/lib/vz/snippets/9002_bootstrap
#cloud-config
package_update: true
package_upgrade: true
ntp:
  enabled: true
  servers: ["pool.ntp.org"]
ssh_deletekeys: true
ssh_genkeytypes: ["ed25519", "rsa"]
runcmd:
- "apt-get -y clean"
- "apt-get -y autoremove --purge"
- "bash -c 'rm /home/ubuntu/.ssh/authorized_keys; exit 0'"
- "bash -c 'find /var/log -type f | while read f; do echo -ne >$f; done; exit 0'"
- "bash -c 'rm -rf /var/lib/cloud/* /var/tmp/* /tmp/* /tmp/.*-unix; exit 0'"
power_state:
  mode: poweroff
EOF
```

Create the template VM:
```
qm stop 9002; qm destroy 9002
qm create 9002 --name ubuntu-2004 --memory 2048 --net0 virtio,bridge=vmbr0
qm importdisk 9002 /tmp/focal-server-cloudimg-amd64.img local
qm set 9002 --scsihw virtio-scsi-pci --scsi0 local:9002/vm-9002-disk-0.raw
qm set 9002 --ide0 local:cloudinit
qm set 9002 --boot c --bootdisk scsi0
qm set 9002 --serial0 socket --vga serial0
qm set 9002 --cicustom "user=local:snippets/9002_bootstrap"
qm set 9002 --ipconfig0 ip=dhcp,ip6=dhcp

qm start 9002
sleep 10;while :; do qm status 9002|grep -q stopped && break; done
qm set 9002 --cicustom ""
qm set 9002 --ipconfig0 ""
qm template 9002
```

#### More Image Cleanup

```
mkdir /etc/systemd/system/motd-news.service.d
cat <<EOF>/etc/systemd/system/motd-news.service.d/override.conf

EOF

mkdir /etc/systemd/timesyncd.conf.d
cat <<EOF>/etc/systemd/timesyncd.conf.d/ntp.conf

Even more cleanup:

apt -y autoremove
```

### Ubuntu 18.04

Download the latest version of the base image to one of your proxmox nodes:

```
curl -sSL https://cloud-images.ubuntu.com/bionic/current/bionic-server-cloudimg-amd64.img >/tmp/bionic-server-cloudimg-amd64.img
```

Create a cloud-init config to bootstrap the template:
```
cat <<'EOF'> /var/lib/vz/snippets/9000_bootstrap

package_upgrade: true
ntp:

- "bash -c 'rm /home/ubuntu/.ssh/authorized_keys; exit 0'"
- "bash -c 'find /var/log -type f | while read f; do echo -ne >$f; done; exit 0'"
- "bash -c 'rm -rf /var/lib/cloud/*; exit 0'"
power_state:
  mode: poweroff
EOF
```

Create the template VM:
```
qm stop 9000; qm destroy 9000
qm create 9000 --name ubuntu-1804 --memory 2048 --net0 virtio,bridge=vmbr0
qm importdisk 9000 /tmp/bionic-server-cloudimg-amd64.img local

qm set 9000 --ipconfig0 ip=dhcp,ip6=dhcp

qm start 9000
sleep 10;while :; do qm status 9000|grep -q stopped && break; done
qm set 9000 --cicustom ""
qm set 9000 --ipconfig0 ""
qm template 9000
```

#### More Image Cleanup

```
apt -y purge apport apport-symptoms bash-completion byobu htop landscape-common lxcfs lxd lxd-client motd-news-config nano ntfs-3g os-prober ufw
apt -y autoremove
