cloud-init

问题 This is a similar problem to a previous SO question, from which I adapted my code How can i use cloud-init to load a datadisk on an ubuntu VM in azure Using a cloud-config file passed through Terraform: #cloud-config disk_setup: /dev/disk/azure/scsi1/lun0: table_type: gpt layout: true overwrite: false fs_setup: - device: /dev/disk/azure/scsi1/lun0 partition: 1 filesystem: ext4 mounts: - [ "/dev/disk/azure/scsi1/lun0-part1", "/opt/data", auto, "defaults,noexec,nofail", ] data "template_file"

问题 I have been trying use cloud-init to partition and mount a datadisk on a Ubuntu VM in azure. Most of the online examples show how to do that for the temporary disk but not for data disk. I tried dabbling around with it with out much luck. Please let me know if I am doing something wrong in the below code or if its not possible to do it with cloud-init #cloud-config device_aliases: {'ephemeral0': '/dev/sdb','datadisk': '/dev/sdc1'} disk_setup: ephemeral0: table_type: mbr layout: True overwrite

问题 I have a simple cloud-init user data that I am passing in to ec2. I set this data on my ec2 instance by right clicking the instance and setting the user data in there. Following is my cloud-init user data #cloud-config runcmd: - [ ls, -l, / ] - [ sh, -xc, "echo $(date) ': hello world!'" ] - [ sh, -c, echo "=========hello world'=========" ] - [ touch, /home/ec2-user/hello.txt ] final_message: "The system is finally up, after 10 seconds" I got this example from here and I added the touch

问题 I'm writing a CloudFormation template and I'm trying to debug the user-data script I provide in the template. How can I run the cloud-init manually and make it perform the same actions it does when starting a new instance? 回答1: You can just run it like this: /usr/bin/cloud-init -d init This runs the cloud init setup with the initial modules. (The -d option is for debug) If want to run all the modules you have to run: /usr/bin/cloud-init -d modules Keep in mind that the second time you run

问题 I've got a custom hardended RHEL 7.5 custom AMI. I want to use user data to complete some deploy time configuration. I've already ensured that /var/lib/cloud/* is removed before I create the AMI. These are the contents of my user data: echo "My script fired." >> /tmp/test.txt echo "This line should produce an output log." The file /tmp/test.txt is present, indicating the my script did indeed run. However, the expected result of the second statement is that a file /var/log/cloud-init-output

问题 I have a simple bash script I'm trying to pass to an AWS EC2 ubuntu instance via a Powershell script using the AWS Library. #!/bin/bash apt-get update apt-get upgrade Heres the powershell script that encodes the file contents in base64 and calls the cmdlet that starts the EC2 instance: $fileContent = Get-Content $UserDataTarget $fileContentBytes = [System.Text.Encoding]::UTF8.GetBytes($fileContent) $fileContentEncoded = [System.Convert]::ToBase64String($fileContentBytes) $MasterInstance = New

问题 I've installed Python 3.6 instead of the default 3.5 release on a new cloud server (Ubuntu 16.04). After I restarted the server, I found that it failed to execute cloud-init at startup with the following errors in the syslog . Sep 20 16:16:14 cloud-init[1310]: Traceback (most recent call last): Sep 20 16:16:14 cloud-init[1310]: File "/usr/bin/cloud-init", line 9, in <module> Sep 20 16:16:14 cloud-init[1310]: load_entry_point('cloud-init==0.7.9', 'console_scripts', 'cloud-init')() Sep 20 16:16
