How to apply a tag to the azure resource group using PowerShell?
Like Azure VM, we can apply the azure tags to the resource group or any other resources. The tagging works on the resource ID and in azure, all the resources come with the resource ID property.To apply the tag to the azure resource group, we first need to use get the resource group details to use its resource ID. The below code shows that how we can apply the new tag to the azure resource group.ExamplePS C:\> $rg = Get-AzResourceGroup -Name AnsibleTestRG PS C:\> $tag = @{Owner='Chirag'; CostCenter='USFinance'} PS C:\> New-AZTag -ResourceId $rg.ResourceId -Tag $tag -VerboseOutput
Read MoreWhat is the difference between the New-AZTag and Update-AZTag command in Azure PowerShell?
New-AZTagWhen we use the New-AZTag command, it removes all the tags from the particular resource and adds a new tag. This command is generally helpful when we are creating a new resource and we want to apply the tag for it.Update-AZTagWhen we use the Update-AZTag command, it updates, deletes, and replaces the Azure tags. We need to make sure that when we are applying the tag to any existing resource which is already tagged, the Update-AZTag command should be used otherwise New-AZTag command will remove all the previous applied tags and it will add new tags.
Read MoreCheck that the element is clickable or not in Selenium WebDriver
We can check if the element is clickable or not in Selenium webdriver using synchronization. In synchronization, there is an explicit wait where the driver waits till an expected condition for an element is met.To verify, if the element can be clicked, we shall use the elementToBeClickable condition. A timeout exception is thrown if the criteria for the element is not satisfied till the driver wait time.SyntaxWebDriverWait wt = new WebDriverWait(driver, 5); wt.until(ExpectedConditions.elementToBeClickable (By.className("s-buy")));We have to add - import org.openqa.selenium.support.ui.ExpectedConditions and import org.openqa.selenium.support.ui.WebDriverWait statements to implement ExpectedConditions in our code.Exampleimport org.openqa.selenium.By; import org.openqa.selenium.WebDriver; import org.openqa.selenium.WebElement; import org.openqa.selenium.chrome.ChromeDriver; import java.util.concurrent.TimeUnit; import ...
Read MoreHow to delete the specific tag of Azure VM using PowerShell?
To delete the specific tag of the Azure VM, we can use the Delete property of the Operation parameter in the Update-AZTag command. In the below example, we have the below tags of the Azure VM TestMachine2k12.Key Value --- ----- Patching_Day Sunday Owner ChiragWe need to delete the Patching_Day tag and for that, we also need its value. The below command will delete the specified tag from the Azure VM.PS C:\> $vm = Get-AzVM -VMName TestMachine2k12 PS C:\> $tag = @{'Patching_Day'='Sunday'} PS ...
Read MoreHow to import the tags in Azure?
In the previous article, we have seen that we can export the Azure resource tags in the JSON file or CSV format. There are some cases when you rebuild your resource and you might need to restore your tags or someone with the authorized person to have azure resource access and he accidentally deletes the tags and we need to restore them. In such cases, if we have the tags backup already we can import them to the resources.In the below example, we suppose we have the Azure VM tags backup stored in the CSV file format and after rebuilding ...
Read MoreHow to Export the azure VM tags using PowerShell?
There are two ways to get the applied azure VM tags using PowerShell.Using Tags Property of the Azure VMUsing the Get-AZTag command.ExamplePS C:\> Get-AzVM -VMName Testmachine2k12 | Select -ExpandProperty Tags Key Value --- ----- Patching_Day Sunday Owner ChiragAnother way is by using the Get-AZTag command.PS C:\> $vm = Get-AzVM -VMName TestMachine2k12 PS C:\> Get-AzTag -ResourceId $vm.Id | Select -ExpandProperty PropertiesOutputTagsProperty ------------ {[Owner, Chirag], [Patching_Day, Sunday]}We need to export this tag and the best way to store the tags is using the JSON file.Get-AzVM -VMName Testmachine2k12 | Select -ExpandProperty Tags ...
Read MoreHow to add the new tag to Azure VM using PowerShell?
To add the new tag of Azure VM using PowerShell, we need to use the New-AZTag command. Please note: If you have already tags applied to the VM, you need to use the Update-AZTag command to merge with the available Azure Tags otherwise all the previous applied.For example, We have the below VM called TestMachine2k12 and after signing to the Azure account we need VMs resource ID to apply the tag to the VM.We will use a tag in the HastTable format so we will have its Key and a Value. We need to apply the below new tag.Example$tag = ...
Read MoreUse Declarations in Rust Programming
Use Declarations in Rust are used to bind a full path to a new name. It can be very helpful in cases where the full path is a bit long to write and invoke.In normal cases, we were used to doing something like this:use crate::deeply::nested::{ my_function, AndATraitType }; fn main() { my_function(); }We invoked the use declaration function by the name of the function my_function. Use declaration also allows us to bind the full path to a new name of our choice.ExampleConsider the example shown below:// Bind the `deeply::nested::function` path to `my_function`. use deeply::nested::function as my_function; ...
Read MoreSuper and Self Keywords in Rust Programming
Whenever we want to remove the tedious long importing paths of functions that we want to invoke, either from the same function or from a different module, we can make use of the super and self keywords provided in Rust.These keywords help in removing the ambiguity when we want to access the items and also prevent unnecessary hardcoding of paths.ExampleConsider a simple example shown below:fn function() { println!("called `function()`"); } mod cool { pub fn function() { println!("called `cool::function()`"); } } mod my { fn function() { println!("called `my::function()`"); ...
Read MoreChannels in Rust Programming
Channels are a medium that allow communication to take place between two or more threads. Rust provides asynchronous channels that enable communication between threads.Channels in Rust allow a unidirectional flow of communication between two endpoints. These two endpoints are Sender and Receiver.ExampleConsider the example shown below −use std::sync::mpsc::{Sender, Receiver}; use std::sync::mpsc; use std::thread; static NTHREADS: i32 = 3; fn main() { let (tx, rx): (Sender, Receiver) = mpsc::channel(); let mut children = Vec::new(); for id in 0..NTHREADS { let thread_tx = tx.clone(); let child = thread::spawn(move || { ...
