Receive and delete message from a SQS queue.

Receive and delete messages from a SQS queue


The following code creates and sends a message to the SQS queue.

The QueueUrl parameter sets the URL to the queue where the message will be sent. The DelaySeconds parameter sets the delay, in seconds, for the message to be sent. The MessageAttributes parameter specifies the message attributes, such as the queue name and the message body. The MessageBody parameter specifies the message body.

Send a message to a queue


The code creates a new sqs client, and then deletes the queue with the given queue URL.

Delete a SQS queue


The above code will create a sqs client and get the URL for the queue named "queuename".

Get the URL for a queue

Create a SQS queue using the `boto3` library.

This code creates a new Scanner object. The Scanner object can be used to parse text from a stream, such as a file.

The import statement imports the storeToRefs function, which is located in the pinia module. This function allows you to convert a store object into a reference to that store. This reference can then be used to access the properties and methods of that store object.

The code tries to stop the specified EC2 instances. If the instances aren't stopped, the code prints an error and terminates.

Stop EC2 instance


When this line of code is executed, the DryRun flag is set to True, which tells the code to run the command without actually starting any instances. If an error occurs while trying to start instances, an exception is raised and the code prints out the error.

Start EC2 instance


The code imports the boto3 library. Next, it creates an instance of the EC2 object. Finally, it calls the describe_instances() method on the EC2 object, passing in the instance as the first argument.

The describe_instances() method returns a dictionary containing information about the specified instance. In this case, the method returns a dictionary containing the following keys:

Name: The name of the instance

State: The state of the instance

AMI: The Amazon Elastic Compute Cloud (Amazon EC2) instance ID

 availability_zone: The Availability Zone the instance is located in

region: The region of the world where the instance is located

ami_id: The Amazon Elastic Compute Cloud (Amazon EC2) instance ID

The list of attributes returned by the describe_instances() method is broad, but some of the more important attributes include the name, state, availability zone, and region of the instance.

EC2 describe instances


The code downloads a file from Amazon S3 using the boto3 client. First, it creates a connection to the S3 service. After that, it creates a file object and opens it for writing. Finally, it instructs the S3 client to download the file from the S3 service and store it in the specified bucket.

Download a file from s3

Upload file in S3


To list metrics in CloudWatch, first create a CloudWatch client. Next, use the get_paginator() function to get the paginator object. This object allows you to query CloudWatch using the pagination interface. Finally, use the paginate() function to iterate through the results of the query. Note that the query uses the Dimensions and MetricName parameters to specify the query parameters. The Namespace parameter specifies the namespace under which the results should be retrieved.

List cloudwatch metrics



This tells the browser to use the English language.

ISO Country code



The code connects to a database, and then queries it for information. If there are any errors, they are thrown. The resulting output will show the connected status and the results of the query.

Query on a MySQL DB



The code between the < and > represents the HTML code for an input field. You would need to create a new input field with that name and type in the password you want to protect.

Input type password



This is a textarea that will hold 20 characters. The textarea will automatically wrap to the next line if it gets too long.

The code is saying to wait for the storage object named "filePath" to be populated with the contents of the file located at "filePath" as encoded in UTF-8. The first argument is the path to the file. The second argument is an object specifying the options to the put call. The third argument is an object specifying the prefix for the private items. The fourth argument specifies the bucket where the items should be stored.
