It will not enable cloud-init if either: •The file /etc/cloud/cloud-init.disabledexists •The kernel command line as found in /proc/cmdlinecontains cloud-init=disabled. When running in a container, the kernel command line is not honored, but cloud-init will read an environment. #cloud-config # # This is an example file to automatically setup and run puppetd # when the instance boots for the first time. # Make sure that this file is valid yaml before starting instances. # It should be passed as user-data when starting the instance. puppet: # Every key present in the conf object will be added to puppet.conf: # [name] # subkey=value # # For example the configuration. The cloud-init code then searches for a DataSource on every boot. If your DataSource will not be present on every boot, then you can set this option to 'True', and maintain (remove) that link before the image will be booted as a new instance. Default: false output Configure where output from the various stages of cloud-init will be saved The cloud-init subcommand can generate MIME multi-part files: make-mime. make-mime subcommand takes pairs of (filename, text/ mime subtype) separated by a colon (e.g. config.yaml:cloud-config) and emits a MIME multipart message to stdout

Cloud-init is a set of init scripts for cloud instances. Cloud instances need special scripts to run during initialization to retrieve and install ssh keys and to let the user run various scripts cloud-init. For LXC images, the generator disables cloud-init by disabling any cloud-init services, and creates the file cloud-init.disable which is checked by cloud-init on startup. For LXD images, the generator creates templates depending on the provided name. Valid names are user-data, meta-data, vendor-data and network-config

Cloud-init is the perfect tool to provision a new instance. You can provide provisionning instructions to cloud-init using the cloud-init key of the user_data facility. In order for the user_data to be effective, it has to be added prior to starting the instance since cloud-init gets activated early in the first phases of the boot process systemd: Render generator from template to account for system differences. The systemd generator used had a hard coded path for the location target file to create. This path does not apply to all distributions. Make the generator and template to have the path set during build time Edit config.js and run node make-cloud-init.js to output a Cloud Init file. Start an instance (via API or manually) on your cloud provider and specify the Cloud Init file as User Data. After the box is built, SSH in as your chosen user, on your chosen port. You might wish to check the output of the Cloud Init in /var/log/cloud-init-output.log

  3. The content_type is very important in this case.template_cloudinit_config can work with rendered templates allowing for cloud-init configs templates with dynamic parts.. Note: gzip and base64_encode settings can be set to false for easier debugging of the content on the created instance. Otherwise content on the server is usually both gzip and base64 encoded
  4. As cloud-init needs to be able to enable and disable itself at runtime, it does not use a static systemd unit file, but a generator, i.e. a little script which runs at an early boot stage and creates systemd units and targets
  5. Cloud-init is the perfect tool to provision a new instance. You can provide provisionning instructions to cloud-init using the cloud-init key of the user_data facility. In order for the user_data to be effective, it has to be added prior to starting the instance since cloud-init gets activated early in the first phases of the boot process
  6. This article explains the support that exists for cloud-init to configure a virtual machine (VM) or virtual machine scale sets at provisioning time in Azure. These cloud-init configurations are run on first boot once the resources have been provisioned by Azure. VM Provisioning is the process where the Azure will pass down your VM Create.

Cloud-init is a set of init scripts for cloud instances. Cloud instances need special scripts to run during initialization to retrieve and install ssh keys and to let the user run various scripts. Built by: mbox_admin: State: complete Volume: DEFAULT: Started: Wed, 21 Jul 2021 11:06:32 UTC Note: If you are installing the cloud-init package for capturing a virtual machine, and already have the activation engine installed, you must uninstall the activation engine. To check if the activation engine RPMs are installed, run # rpm -qa | grep activation on the virtual machine. If the RPMs are present, refer to the Uninstalling the activation engine topic for details to remove them

Annotations. Line 1: the user-data file always has to start with the line '# cloud-config'. Line 2-3: These lines follow the regular YAML syntax of key-value entries. The lines defines the hostname and the FQDN that the instance will get.. Line 4-26: The write-files section instructs cloud-init to create files, with the specified properties and content on the instance cloud-init. cloud-init functions similarly: provision an adminstrative user, and SSH credentials. It can be used to install an automation agent as well, and just like Vagrant, it can run arbitrary scripts. At this stage it begins to overlap with automation systems so it is up to the user to draw the line where cloud-init ends and the automation. 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


Recently I've trace how cloud-init is being run. First, I try to find service file in /etc/system/system or /lib/systemd/system. Although I can locate the unit files, I can't see any systemd target that will bring up these cloud-init services Random port number generator. This port generator generates a random TCP/UDP port between 1024 and 65536. Your personal random port: Port 55418. Click here to generate a new random port number The generator is the first one, and the simplest one: it will determine whether we are even trying to run cloud-init, and based on that, whether it should enable or disable the processing of data files. Cloud-init will not run if there are kernel command-line directives to disable it, or if a file called /etc/cloud/cloud-init.diabled exists

With reference to the cloud-init support, we would love to have this option working and available, but currently this is beyond our control. As soon as it available, we will definitely equip our modules with this feature. We have attempted to create some sort of workaround with utilization of qemu quest agent, until cloudbase-init becomes. Cloud-init's systemd generator reduces the datasources that will be searched to only those that may be present. - Cloud-config schema validation: 'cloud-init devel schema' command can validate a cloud-config for some config modules, saving you time and resources. More coverage of modules will come this next release

Ansible is a radically simple IT automation platform that makes your applications and systems easier to deploy and maintain. Automate everything from code deployment to network configuration to cloud management, in a language that approaches plain English, using SSH, with no agents to install on remote systems. https://docs.ansible.com Provision Infrastructure with Cloud-Init. 5 min; Products Used; This tutorial also appears in: Associate Tutorials. When you create a generic compute resource in Terraform, your virtual machine (VM) may not have much capability because it is a fresh install and needs to be provisioned with the software you want to use

If cloud-init is not disabled, the generator injects cloud-init.target into the multi-user.target. This target uses WantedBy to pull several units (.service files) that ultimately call /usr/bin/cloud-init, passing it different command-line options. Note that this executable is not a daemon: It does what was requested and then exits, and you won. Network configuration for cloud init (i.e. network-config) named according to networkConfigFileName parameter of builder section specified in ISO builder configuration file.

In most scenarios the easiest way will be to provide user-data via the nocloud data source. The autoinstall config should be provided under the autoinstall key in the config. For example: #cloud-config autoinstall: version: 1. This instruction no longer works, the errors you will get are: dpkg-reconfigure cloud-init (must be run from root) If you type sudo in front of that command you will get into the cloud-init but you cannot select anything Please update the instructions. It works for me. Except that it has to be sudo dpkg-reconfigure cloud-init

Cloud-Init: The Good Parts. Cloud-Init is the de facto industry standard for early-stage initialization of virtual machines in the cloud, but few engineers are familiar with everything that it has to offer. If playback doesn't begin shortly, try restarting your device One of the biggest advantages of cloud-init is the ability to generate and set your server's hostname and SSH keys on initial boot. Rather than manually entering and verifying this information by hand, cloud-init allows users to automatically handle this process through code which can be replicated and reused as needed

Initializing a Machine Image using cloud-init. You can initialize a software event broker cloud or machine image with the cloud-init utility. At start-up, cloud-init iterates through a list of provisioned datasources looking for valid meta-data and user-data. meta-data is supplied as key value pairs, and can be used to configure instance specific parameters such as instance-id, hostname, and. The following is a simple example of how to provision and pass custom data to an Ubuntu Linux VM: In this example, custom-data.txt could be a cloud-init configuration file, or simply a shell script (as long as it starts with #!, then cloud-init will execute it). Give it a try Cloud-init has a concept of a module sempahore, which basically consists of the module name and its frequency. These files are used to ensure a module is only ran per-once, per-instance, per-always. This folder contains sempaphore files which are only supposed to run per-once (not tied to the instance id) cloud-init has a number of tools and logs, but the most useful for debugging will be /var/log/cloud-init-output.log it will tell you what modules ran and whether they were successful for not. I have found that occasionally, using sudo cloud-init collect-logs and extracting the resulting tar file is very useful for figuring out everything it's.

My First Cloud-Init Scripts.
