It was originally designed for the Ubuntu distribution of Linux in Amazon EC2, but is now supported on many Linux and UNIX distributions in every major cloud preserve_sources_list: (boolean) By default, cloud-init will generate a new sources list in /etc/apt/sources.list.d based on any changes specified in cloud config. To disable this behavior and preserve the sources list from the pristine image, set preserve_sources_list to true.. The preserve_sources_list option overrides all other config keys that would alter sources.list or sources.list.d.

  1. Cloud-init is the standard for customizing cloud instances and now multipass can also make use of cloud-init to customize an instance during launch. Below is an example of launching a new VM with cloud-init user-data: multipass launch -n my-test-vm --cloud-init cloud-config.yaml user-data Forma
  2. Cloud-init is actually meant for the cloud platforms like AWS and Openstack. This is a work around to get it to work with vmware. Essentially, this is like creating a boot disk that will run some commands on your VM for you. Using this method, you will have to use the ISO. You can also use tools like Chef or Ansible to do the same thing, but.
  3. Introduction. The cloud-init program that is available on recent distributions (only Ubuntu 14.04 and CentOS 7 at the time of this writing) is able to consume and execute data from the user-data field of the DigitalOcean metadata service.This process behaves differently depending on the format of the information it finds.

Cloud-Init Creating a VM using a cloud image is cool, but there's a problem with this approach, we didn't get any chance to customize the installation. All the configurations that are usually done in install time—setting the hostname, username, password, importing SSH key, we didn't get to do any of that With Cloud-init it is possible to inject informations such as ssh keys, network information or user profiles in an standarized way at boot time. The benefit of using Cloud-init is the pre-provisioning of necessary configuration items such as a static ip address or a default user with activated ssh public key authentication David Duncan- Hands-on building an AMI pipeline using CentOS Stream 8 and cloud-init.

If both the XenAPI agent and cloud-init are present in an image, cloud-init handles ssh-key injection. The system assumes cloud-init is present when the image has the cloud_init_installed property. Use cloud-init to fetch the public key¶ The cloud-init package automatically fetches the public key from the metadata server and places the key in. cloud-init has the ability to generate and set a randomized password for system users. This functionality is enabled at runtime by passing cloud-config data such as: chpasswd: list: | user1:RANDOM. When used this way, cloud-init logs the raw, unhashed password to a world-readable local file bootcmd: - [ cloud-init-per, once, mkfs, -t, ext4, /dev/nvme1n1 ] Ideally it'd happen all before the user gets created since the home directory of the new user is going to be on this new mount. If the instance is stopped and started/restarted I'd not want to ideally lose all data by the reformatting happening again on boot Use the following command-line to install cloud-init on Red Hat-based systems. yum -y install cloud-init.

Today, I had the need to experiment with rerunning cloud-init on a virtual machine created with multipass. You can use cloud-init with multipass by specifying a cloud-init.yaml file when creating your instance. e.g, multipass launch --name my-instance --cloud-init ./cloud-init.yaml This is all well and good and works as you would expect.

Use Cloud-Init to configure the system during installation, first boot and package change. Cloud-Init was originally developed to provide early initialization of cloud instances. Click here to learn more about the initial Cloud-Init configuration. Note: Cloud-Init functionality is supported for the KVM virtualization only To prevent cloud-init and dhclient from changing custom DNS, use following steps: Edit /etc/dhcp/dhclient.conf and use. supersede domain-name-servers,; to replace DNS with custom DNS. If you do not want to replace DHCP based DNS but prepend some other DNS with higher priority then use below instead: prepend domain-name-servers 4. Many Cloud-Init images rely on this, as it is an requirement for OpenStack images. qm set 9000 --serial0 socket --vga serial0. In a last step, it is helpful to convert the VM into a template. From this template you can then quickly create linked clones. The deployment from VM templates is much faster than creating a full clone (copy) The cloud-init package is an open-source application built by Canonical that is used to bootstrap Linux images in a cloud computing environment, such as Amazon EC2. Amazon Linux contains a customized version of cloud-init. It enables you to specify actions that should happen to your instance at boot time. You can pass desired actions to cloud.

Cloud-init and the live server installer. We are working on enabling cloud-init during the subiquity live session. The motivation for this is to let users of systems with basic terminals complete the installation via SSH. However it also provides other interesting possibilities. The default cloud.cfg in the live session by default will create a. After a few seconds (maybe minutes depending on your cloud-init file) your VM should be up and running. Now you can check the results by executing vagrant ssh.In my example it is easy to verify that a user test_user_unique_name is present by executing cat /etc/passwords and that a package python-is-python3 was installed with python --version (it outputs Python 3 Change the system hostname. If you have a public DNS name registered for the IP address of your instance (such as webserver.mydomain.com), you can set the system hostname so your instance identifies itself as a part of that domain.This also changes the shell prompt so that it displays the first portion of this name instead of the hostname supplied by AWS (for example, ip-12-34-56-78)
