qm cloud init (with examples)
1: Configure cloudinit settings for a specific user and set password for the user
qm cloud-init vm_id -user=user -password=password
Motivation: When creating a virtual machine, it is often necessary to set up a specific user account and password for initial login. This use case allows you to configure the cloudinit settings for a virtual machine with the specified user and password.
Explanation:
vm_id: The ID of the virtual machine you want to configure.-user=user: Sets the username for the virtual machine.-password=password: Sets the password for the specified user.
Example output: None
2: Configure cloudinit settings for a specific user and set password for the user with a specific SSH key
qm cloud-init vm_id -user=user -password=password -sshkey=ssh_key
Motivation: To enhance security and simplify authentication, it is common to use SSH keys instead of passwords for remote access. This use case allows you to configure the cloudinit settings for a virtual machine with a specific user, password, and SSH key.
Explanation:
vm_id: The ID of the virtual machine you want to configure.-user=user: Sets the username for the virtual machine.-password=password: Sets the password for the specified user.-sshkey=ssh_key: Sets the SSH public key for the specified user.
Example output: None
3: Set the hostname for a specific virtual machine
qm cloud-init vm_id -hostname=hostname
Motivation: The hostname of a virtual machine is the unique identifier used to access it on the network. Setting the hostname allows for easy identification and management of multiple virtual machines.
Explanation:
vm_id: The ID of the virtual machine you want to configure.-hostname=hostname: Sets the hostname for the virtual machine.
Example output: None
4: Configure the network interface settings for a specific virtual machine
qm cloud-init vm_id -ipconfig ipconfig
Motivation: Network configuration is essential for proper communication between virtual machines and other devices on the network. This use case allows you to configure the network interface settings for a specific virtual machine.
Explanation:
vm_id: The ID of the virtual machine you want to configure.-ipconfig ipconfig: Sets the IP configuration for the network interface of the virtual machine.
Example output: None
5: Configure a shell script to execute before cloud-ini is run on a virtual machine
qm cloud-init vm_id -pre script
Motivation: Sometimes, it is necessary to run certain tasks or setup steps before the cloud-init process begins on a virtual machine. This use case allows you to configure a shell script that will be executed before the cloud-init process starts.
Explanation:
vm_id: The ID of the virtual machine you want to configure.-pre script: Specifies the shell script to be executed before the cloud-init process.
Example output: None
By using the qm cloud-init command with these different use cases, you can configure various settings for virtual machines managed by Proxmox Virtual Environment. Whether it’s setting up user accounts, configuring network interfaces, or executing custom scripts, the qm cloud-init command provides flexibility and customization options for your virtual machine deployments.
