user-data

What is the order of the directives in the cloud-config section of a cloud-init user-data object. This is important to avoid race type conditions. I know bootcmd runs early and before runcmd, but is there a good list of the order of all the methods? From https://git.launchpad.net/cloud-init/tree/config/cloud.cfg (thanks to garbelini) # The modules that run in the 'init' stage cloud_init_modules: - migrator - ubuntu-init-switch - seed_random - bootcmd - write-files - growpart - resizefs - set_hostname - update_hostname - update_etc_hosts - ca-certs - rsyslog - users-groups - ssh # The modules

I have an EC2 ASG on AWS and I'm interested in storing the shell script that's used to instantiate any given instance in an S3 bucket and have it downloaded and run upon instantiation, but it all feels a little rickety even though I'm using an IAM Instance Role , transferring via HTTPS, and encrypting the script itself while at rest in the S3 bucket using KMS using S3 Server Side Encryption ( because the KMS method was throwing an 'Unknown' error ). The Setup Created an IAM Instance Role that gets assigned to any instance in my ASG upon instantiation, resulting in my AWS creds being baked into

I searched a lot of topic about "user-data script is not working" in these few days, but until now, I haven't gotten any idea about my case yet, please help me to figure out what happened, thanks a lot! According to AWS User-data explanation: When you launch an instance in Amazon EC2, you have the option of passing user data to the instance that can be used to perform common automated configuration tasks and even run scripts after the instance starts. So I tried to pass my own user-data when instance launch, this is my user-data: \#!/bin/bash echo 'test' > /home/ec2-user/user-script-output.txt

I'm having trouble understanding what all of the fields in a JSON datasource for a jqGrid means and I am not seeing any documentation for it anywhere. The example I'm trying to understand is this: http://www.trirand.com/blog/jqgrid/jqgrid.html and then the first example under "JSON Data" The JSON data can be accessed here: http://www.trirand.com/blog/jqgrid/server.php?q=2&rows=10&page=2 One of the things that confuse me in the JSON is this snipplet: "userdata":{"amount":1520,"tax":202,"total":1724,"name":"Totals:"} What exactly is this doing? Oleg It is very easy to explain. The server produce

When creating an application that will be targeted to many versions of Windows what is the best practice to determine where application specific data should be stored. Specifically: Application Specific Data (e.g. app config data) User Specific Data/Settings I know on Windows Vista for instance there are environment variables, like %APPDATA%, that could be used, but what about Windows 7, Windows XP, Windows 98. My main question is, does Microsoft have a best practices doc for this, outlining the file system locations for the different types of data (app vs. user) and the security implications

I need to pass userData to jqgrid , but can't find any examples of how to do this. Here's my attempt: Sent from the server: { total: 25, page: currentpage, userData: {foo: 'bar'}, rows: myRows } and in jqgrid: var data = jQuery("#grid").getGridParam('userData'); How can I send userData and read it from jqgrid? EDIT: I know my userData is being sent, because I can see it in Fiddler . I think I'm just stuck on how to read it on the client side. Oleg In general the usage of userData is pretty simple. jqGrid gives you support to send from the server any additional data which will be saved together
