Edit this page. First, you will bootstrap EC2 instance to install web server and content. Then you will create an EC2 Security Group and allow access on port 80 to the instance. Finally, you will view the content served by the web server. The following diagram provides a high-level overview of the architecture you will implement. Open the user-data. Copy the code as you go through the topics below. Join [ '-' , [! Ref EnvironmentType, webserver ] ].
UserData : Fn::Base64 :! For example:. By default, the user data scripts are run one time when you launch the instance. If you associate an IAM role with your instance, you don't need to specify credentials to the cmdlets, as applications that run on the instance use the role's credentials to access AWS resources for example, Amazon S3 buckets.
Specify a Windows PowerShell script using the powershell tag. If you're using the Amazon EC2 API or a tool that does not perform base64 encoding of the user data, you must encode the user data yourself. If not, an error is logged about being unable to find script or powershell tags to run. The following is an example that encodes using Windows PowerShell. You can specify that user data scripts are run the next time the instance reboots or restarts.
Alternatively, you can specify that user data scripts are run every time the instance reboots or restarts. User data scripts are run from the local administrator account when a random password is generated. Otherwise, user data scripts are run from the System account. Scripts in the instance user data are run during the initial launch of the instance.
If the persist tag is found, user data execution is enabled for subsequent reboots or starts. To view the folder, you must show hidden files and folders. Info: Initializing user-data state — The start of user data execution. Info: Frequency is: always — If the user data task is running on every boot.
Info: Frequency is: once — If the user data task is running just once. Stage: postReadyUserData execution completed — The end of user data execution. Message: The output from user scripts — If user data scripts are run, their output is logged. The following information is logged when the user data is run:. When you update instance user data, user data scripts are not run automatically when you reboot or start the instance.
However, you can enable user data execution so that user data scripts are run one time when you reboot or start the instance, or every time you reboot or start the instance. If you choose the Shutdown with Sysprep option, user data scripts are run the next time the instance starts or reboots, even if you did not enable user data execution for subsequent reboots or starts.
The user data scripts will not be executed on subsequent reboots or starts. To run a task in user data on first boot, set frequency to once. To run a task in user data on every boot, set frequency to always. Disconnect from your Windows instance. To run updated scripts the next time the instance is started, stop the instance and update the user data. For more information, see View and update the instance user data.
You can specify instance user data when you launch the instance. If the root volume of the instance is an EBS volume, you can also stop the instance and update its user data. The example in the following image creates a file in the Windows temporary folder, using the current date and time in the file name. When you select As text , the Amazon EC2 console performs the base64 encoding for you. You can view the instance user data for any instance, and you can update the instance user data for a stopped instance.
Select the instance and choose Actions , Instance state , Stop instance. When you stop an instance, the data on any instance store volumes is erased. To keep data from instance store volumes, be sure to back it up to persistent storage. When prompted for confirmation, choose Stop. It can take a few minutes for the instance to stop.
This is the most important part of a userdata. To retrieve the metatable added to the userdata, we would use the getmetatable function. For example:. When using table. Although userdatas are unknown and undocumented, they can have some neat use-cases. These are not necessary for development. A function that makes a table readonly. Symbols are used in Roblox libraries like Roact to represent markers kind of like Enums.
For example in Roact :. Hopefully you learned more about userdatas and there is no confusion about the data type. Have a good day or night. Stay safe! I would recommend adding a section explaining what userdata actually are in general, not just newproxy.
Also explain the difference between userdata created by newproxy and C-side userdata. Edit: wait this is an old thtead? I am extremely sorry to boost it idk how it got boosted automatically though…. Userdatas are for storing and managing arbitary values stored in C and representing them as an object in Lua. Python is available by default with the build itself, but also it must be in the system PATH. The following cloud-config directives are supported:.
It can be a list of items or only one item, with the following attributes:. The users are defined as a list. Each element from the list represents a user. Each user can have the the following attributes defined:. The servers and pools are aggregated, servers being the first ones in the list.
On Windows, there is no difference between an NTP pool or server. A command can be defined as a string or as a list of strings, the first one being the executable path. On Windows, the commands are aggregated into a file and executed with cmd. The userdata exit codes can be used to request a reboot: File execution.
The reboot is performed at the end of the cloud-config execution after all the directives have been executed. On 32bit OSes, the return value will be the System32 directory, which contains 32bit programs. On 64bit OSes, the return value may be different, depending on the Python bits and the sysnative parameter. If the Python interpreter is 32bit, the return value will be System32 containing 32bit programs if sysnative is set to False and Sysnative otherwise.
On a WOW case 32bit interpreter on 64bit OS , a return value of System32 will point to the physical SysWOW64 directory and a return value of Sysnative , which is consolidated by the existence of this alias, will point to the real physical System32 directory found on disk.
If the OS is still 64bit and there is no WOW case that means the interpreter is 64bit , the system native concept is out of discussion and each return value will point to the physical location it intends to. Its purpose is to provide the correct system paths by taking into account the Python interpreter bits too, because on a 32bit interpreter version, System32 is not the same with the System32 on a 64bit interpreter.
Also, using a 64bit interpreter, the Sysnative alias will not work, but the sysnative parameter will take care to return SysWOW64 if you explicitly want 32bit applications, by setting it to False.

Or whoami this all runs as root? Remember that any files you create will be owned by root ; if you need non-root users to have file access, you should glm floor plan app the permissions accordingly in the script.

You can pass two types of user data to Amazon EC2: shell scripts and cloud-init directives. You can also pass this data into the launch wizard as plain text, as. For User Data, select Enable UserData execution for next service start. Disconnect from your Windows instance. To run updated scripts the next time the instance. Cloud-config is the simplest way to accomplish some things via user-data. Using cloud-config syntax, the user can specify certain things in a human friendly.
