尝试编写脚本在 cloud-int VM 上安装 qemue 代理

  • 772

我目前正在使用 Proxmox 来部署一些 VMS。我正在使用此处提供的脚本。

我当前的脚本是这样的

#!/bin/bash

#Create template
#args:
# vm_id
# vm_name
# file name in the current directory
function create_template() {
    #Print all of the configuration
    echo "Creating template $2 ($1)"

    #Create new VM 
    #Feel free to change any of these to your liking
    qm create $1 --name $2 --ostype l26 
    #Set networking to default bridge
    qm set $1 --net0 virtio,bridge=vmbr0
    #Set display to serial
    qm set $1 --serial0 socket --vga serial0
    #Set memory, cpu, type defaults
    #If you are in a cluster, you might need to change cpu type
    qm set $1 --memory 1024 --cores 4 --cpu host
    #Set boot device to new file
    qm set $1 --scsi0 ${storage}:0,import-from="$(pwd)/$3",discard=on
    #Set scsi hardware as default boot disk using virtio scsi single
    qm set $1 --boot order=scsi0 --scsihw virtio-scsi-single
    #Enable Qemu guest agent in case the guest has it available
    qm set $1 --agent enabled=1,fstrim_cloned_disks=1
    #Add cloud-init device
    qm set $1 --ide2 ${storage}:cloudinit
    #Set CI ip config
    #IP6 = auto means SLAAC (a reliable default with no bad effects on non-IPv6 networks)
    #IP = DHCP means what it says, so leave that out entirely on non-IPv4 networks to avoid DHCP delays
    qm set $1 --ipconfig0 "ip6=auto,ip=dhcp"
    #Import the ssh keyfile
    # qm set $1 --sshkeys ${ssh_keyfile}
    #If you want to do password-based auth instaed
    #Then use this option and comment out the line above
    qm set $1 --cipassword password
    #Add the user
    qm set $1 --ciuser ${username}
    #Resize the disk to 8G, a reasonable minimum. You can expand it more later.
    #If the disk is already bigger than 8G, this will fail, and that is okay.
    qm disk resize $1 scsi0 8G

    #Make it a template
    qm template $1

    #Remove file when done
    rm $3
}


#Path to your ssh authorized_keys file
#Alternatively, use /etc/pve/priv/authorized_keys if you are already authorized
#on the Proxmox system
export ssh_keyfile=/root/id_rsa.pub
#Username to create on VM template
export username=root

#Name of your storage
export storage=main

#The images that I've found premade
#Feel free to add your own

## Fedora 37
#Image is compressed, so need to uncompress first
wget https://download.fedoraproject.org/pub/fedora/linux/releases/37/Cloud/x86_64/images/Fedora-Cloud-Base-37-1.7.x86_64.raw.xz

## CentOS Stream
#Stream 8
wget https://cloud.centos.org/centos/8-stream/x86_64/images/CentOS-Stream-GenericCloud-8-20220913.0.x86_64.qcow2
create_template 930 "temp-centos-8-stream" "CentOS-Stream-GenericCloud-8-20220913.0.x86_64.qcow2"
#Stream 9 (daily) - they don't have a 'latest' link?
wget https://cloud.centos.org/centos/9-stream/x86_64/images/CentOS-Stream-GenericCloud-9-20230123.0.x86_64.qcow2
create_template 931 "temp-centos-9-stream-daily" "CentOS-Stream-GenericCloud-9-20230123.0.x86_64.qcow2"

现在，为了尝试在每台设备上安装 qemu，我在创建模板之前尝试了类似的操作，但它失败了。所以我不确定是否有更好的方法在 VM 上安装并启用 qemu-agent？

    # Install and enable qemu-guest-agent based on the distribution
    case $2 in
        temp-debian-10 | temp-debian-11 | temp-debian-12-daily)
            qm set $1 --exec "apt update && apt install -y qemu-guest-agent"
            ;;
        temp-ubuntu-20-04 | temp-ubuntu-22-04 | temp-ubuntu-23-04-daily)
            qm set $1 --exec "apt update && apt install -y qemu-guest-agent"
            ;;
        temp-fedora-37)
            qm set $1 --exec "dnf install -y qemu-guest-agent && systemctl enable --now qemu-guest-agent"
            ;;
        temp-centos-8-stream | temp-centos-9-stream-daily)
            qm set $1 --exec "dnf install -y qemu-guest-agent && systemctl enable --now qemu-guest-agent"
            ;;
        *)
            echo "Unsupported distribution: $2"
            ;;
    esac
qemu

    我能够使用 cloud-int 文件修复它

    qm set $1 --cicustom "user=local:snippets/100.yaml"

    文件看起来像这样

    #cloud-config
ssh_pwauth: true
disable_root: false
chpasswd:
  list: |
    root:password
  expire: false

write_files:
  - path: /etc/sudoers.d/cloud-init
    content: |
      Defaults !requiretty

package_update: true
package_upgrade: true
packages:
  - qemu-guest-agent

runcmd:
  - sed -i 's/^#PermitRootLogin.*/PermitRootLogin yes/' /etc/ssh/sshd_config
  - sed -i -e 's/^GSSAPIAuthentication yes/GSSAPIAuthentication no/g' /etc/ssh/sshd_config
  - sed -i -e 's/^PasswordAuthentication no/PasswordAuthentication yes/g' /etc/ssh/sshd_config
  - systemctl restart sshd
  - systemctl enable qemu-guest-agent
  - systemctl start qemu-guest-agent
