问题 Context I am using the https://wiki.jenkins.io/display/JENKINS/Amazon+EC2+Plugin for jenkins which allows me to dynamically provision new cloud instances as build slaves in AWS EC2. I am launching ami-d834aba1 (Amazon Linux 2017.09.1). The plugin supports providing user-data and block device mapping too, currently I provide config like this after reading https://cloudinit.readthedocs.io/en/latest/ User Data #cloud-config repo_update: true repo_upgrade: all package_upgrade: true bootcmd: - [

What is the Cloud-Init equivalent for Windows?

由 心不动则不痛 提交于 2019-12-10 02:30:34
问题 It seems that the stock bootstrapping process is a bit lacking on Windows. Linux has cloud-init which will install packages, store files, and run a bash script from user data. Windows has ec2config but there is currently no support to run a cmd or powershell script when the system is "ready"--meaning that all the initial reboots are completed. There seem to be third party options. For example RightScale has the RightLink agent which performs this function. Are there open source options

cloud-init how to add default user to sudoers.d

问题 I boot strap a centos 6.5 AMI with this user data: #cloud-config users: - default - name: my-user - sudo: ALL=(ALL) NOPASSWD:ALL My machine comes up with the user cloud-user as the default user, not my-user. My public key has been copied to the cloud-user. So, in short, it does not work. If I do this, the default user is my-user: #cloud-config user: my-user sudo: ALL=(ALL) NOPASSWD:ALL But I cannot sudo -i with this user. How can I in userdata set my-user to be the default and have sudo

Where to find logs for a cloud-init user-data script?

问题 I'm initializing spot instances running a derivative of the standard Ubuntu 13.04 AMI by pasting a shell script into the user-data field. This works. The script runs. But it's difficult to debug because I can't figure out where the output of the script is being logged, if anywhere. I've looked in /var/log/cloud-init.log, which seems to contain a bunch of stuff that would be relevant to debugging cloud-init, itself, but nothing about my script. I grepped in /var/log and found nothing. Is there

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 command My expectation was to see the data on the /var/log/cloud-init.log. But I don't see it there. Also I

HOWTO deploy a docker container on aws without using elastic beanstalk or ec2 container service

由 流过昼夜 提交于 2019-12-04 09:39:44
问题 I'd like to use docker containers without having to use elastic beanstalk or ec2 container service. I'd like to upload a .zip file describing the container (like you do with elastic beanstalk) and have a generic ec2 instance run it using docker. When looking into the user data section of a beanstalk-created ec2 instance running a docker container, I see a cloud-init script that downloads a big shell script that does all the setup (Example). I assume that everything that elastic beanstalk does

How to re-run cloud-init without reboot

问题 I am using openstack to create a VM using 'nova boot' command. My image is cloud-init enabled. I pass a --user-data script which is a bash shell format for cloud-init to run during VM boot up time. All this happens successfully. Now my use-case is to re-run cloud-init to execute the same user-data script without rebooting the VM. I saw /usr/bin/cloud-init options and they do talk about running specific modules but nothing is able to make it execute the same user-data script. How can this be
