First, check to see if Python is already installed. You can do this by typing which python in your shell. If Python is installed, the response will be the path to the Python executable. If Python is not installed, go to the Python. We will be using Python 2. Check your version of Python by typing python -V. Your install should work fine as long as the version is 2. You can check for pip by typing which pip. If pip is installed, the response will be the path to the pip executable.
If pip is not installed, follow the instructions at pip. Your version of pip should be 9.
Now, with Python and pip installed, we can install the packages needed for our scripts to access AWS. If nothing is reported, all is well. If there are any error messages, review the setup for anything you might have missed.
Creating Automation documents that run scripts
Before we can get up and running on the command line, we need to go to AWS via the web console to create a user, give the user permissions to interact with specific services, and get credentials to identify that user. Open your browser and navigate to the AWS login page. On the review screen, check your user name, AWS access type, and permissions summary.Rapidmoviez down
It should be similar to the image below. Protect these credentials like you would protect a username and password! Back in the terminal, enter aws configure. Using the credentials from the user creation step, enter the access key ID and secret access key.Kamar ki chuk in english
For the default region name, enter the region that suits your needs. The region you enter will determine the location where any resources created by your script will be located. You can find a list of regions in the AWS documentation. In the shell, enter:. If not, you should see an empty response. If you see any errors, walk through the previous steps to see if anything was overlooked or entered incorrectly, particularly the access key ID and secret access key.
We can get this information with just a few short lines of code.
AWS Systems Manager Automation
This is like a handle to the EC2 console that we can use in our script. That will allow you to run the script directly from the command line. In this case, the procedure looks like this:. This will let us tell our script what type of EC2 instance to create. We can capture the output of the function call which is an instance object. While the command will finish quickly, it will take some time for the instance to be created.
Now that we can programmatically create and list instances, we also need a method to terminate them.In my work as a data scientist, I have come to realize how necessary it is to automate any and every aspect of the workflow.
The project outlined below is all hosted on my github. Apply a dedicated IP address to the instance. Install Python3. Clone python repository to the instance. Create a cron job that will run every hour. Amazon Lightsail is the easiest way to get started with AWS if you just need virtual private servers. Lightsail includes everything you need to launch your project quickly — a virtual machine, SSD-based storage, data transfer, DNS management, and a static IP.
After you create your instance, you can easily connect to it. To begin you will need to sign up at Amazon LightSail. The first month is free which will give you plenty of time to decide if this service is what you need. Once you have logged in, you should see the Lightsail dashboard. Create an Ubuntu Instance. Click on the Create instance button circled above.
Select OS only. Select Ubuntu Select Create Instance. It will take the Ubuntu instance a few minutes to be created. You will also see the IP address assigned to the instance, for my instance the IP address is 3.
This IP address is dynamic and will change every time you reboot the instance.Automation enables you to do the following:.
Build Automation workflows to configure and manage instances and AWS resources. Automation includes several pre-defined Automation documents that you can use to perform common tasks like restarting one or more EC2 instances or creating an Amazon Machine Image AMI.
You can create your own Automation documents as well. Steps run in sequential order. For more information, see Working with Automation documents. Automation documents are Systems Manager documents of type Automationas opposed to CommandPolicySession documents.
Automation documents currently support schema version 0. Command documents use schema version 1. Policy documents use schema version 2. The Automation workflow defined in an Automation document includes one or more steps. Each step is associated with a particular action, or plugin.Download amapiano beats only
The action determines the inputs, behavior, and outputs of the step. Steps are defined in the mainSteps section of your Automation document. Automation supports 20 distinct action types. For more information, see the Systems Manager Automation actions reference.
If you attempt to run more than this, Systems Manager adds the additional executions to a queue and displays a status of Pending. When an Automation completes or reaches a terminal statethe first execution in the queue starts.Essay on an interesting dream for class 5
Each AWS account can queue 1, Automation executions. Automation can simplify common IT tasks such as changing the state of one or more instances using an approval workflow and managing instance states according to a schedule. Here are some examples:. After the approval is received, Automation stops the instance.
For example, you can configure an Automation workflow to stop instances every Friday evening, and then restart them every Monday morning. The update applies a new template. You can configure the Automation to request approval by one or more IAM users before the update begins. For information about how to run an Automation workflow by using State Manager, see Running Automation workflows with triggers using State Manager. Systems Manager includes features that help you target large groups of instances by using Amazon EC2 tags, and velocity controls that help you roll out changes according to the limits you define.
You can configure the Automation workflow to use velocity controls. For example, you can specify the number of instances that should be restarted concurrently. You can also specify a maximum number of errors that are allowed before the Automation workflow is cancelled. Automation offers one-click automations for simplifying complex tasks such as creating golden Amazon Machines Images AMIsand recovering unreachable EC2 instances. You can run custom scripts before and after updates are applied.Subscribe to get all the news, info and tutorials you need to build better business apps and sites.How to install pixel experience
You have the right to request deletion of your Personal Information at any time. You'll learn how to set up the Python scripting environment for first use, and how to enable yourself as a user to create Python scripts to launch virtual machine instances in AWS EC2 as per specific requirements. You'll need some prior understanding of basic Python 3, an AWS account with admin privileges, and experience working on a Linux shell Bash before attempting this how-to.
Follow these steps to create your user credentials:. In the new window, provide a user name and choose the 'Programmatic Access' access type, then click next. The next page will show your keys, as shown below. These are only available once, so it its a good idea to download and save then safely in a secure location.Best statistics book for economics
After creating the user and obtaining the credentials Access ID and Secret keywe can now configure our Python scripting environment with this credential in order to manage EC2. To do that, run the following command from a Bash shell:. Otherwise, an error is thrown, which means the credentials do not work. Before we can jump into how to create EC2 instances, it's important to understand how to create a keypair for EC2 instances, so that they can be accessed later, once the virtual machines are launched programmatically using Python.
The above program not only creates a key pair in AWS, it also captures and stores it on your local machine. You can use this key pair to SSH into the virtual machines later. Please make sure to change the mode of the key pair file to read-only using the following command in bash terminal, otherwise it will be denied access. Once we have this information, it's pretty straight-forward to script this in Python.
After running the above script, now when you go to your EC2 dashboard in AWS console, you'll observe new EC2 instances are being provisioned and are in initialization state, which is expected to complete in a few minutes.
Automating routine cloud operations with AWS Systems Manager and MontyCloud

Operations people. Sign Up Login.The dependency on apps and software programs in carrying out tasks in different domains has been on a rise lately. This necessity has caused many businesses to adopt public cloud providers and leverage cloud automation. This shift is fueled by a demand for lesser costs and easier maintenance. AWS has emerged as a leader in the cloud computing domain and companies leveraging algorithmic DevOps AIOps for better management and streamlined cloud operations.
There are lot of challenges that newbies face when migrating their infrastructure to AWS. The functioning of all services and detailed analysis of infrastructure becomes necessary to perform any operation. Regularly performing DevOps tasks further complicates the problem. This might incur a lot of human resource investment, and the associated risk of human errors is inevitable.
AWS answers these problems through automation. The use of language specific libraries that can be easily incorporated and used in simple scripts comes in handy, when a person has to perform an operation that requires a lot of manual effort.Python Scripting and AWS Automation with Python
For instance, if you were copying a huge number of snapshots from one region to another, and midway realize that you have copied snapshots of unwanted volumes as well. This can prove to be a costly mistake. To avoid such errors and unnecessary headaches, you can transfer the burden to a simple script that takes care of necessary operations. Many devops engineers are stuck in the inertia of performing manual operations in all kinds of devops tasks. Consider the case of uploading a file to multiple S3 buckets- A person not familiar with coding practices will prefer to do the task manually.
This works when the number of buckets are less. For instance, when a s3 buckets are to be uploaded with the same file, the person looks for alternatives to perform the task. This is where scripting comes to the rescue. Few DevOps engineers stay away from writing scripts for cloud automation, thinking it consumes a lot of time.
This argument makes sense when writing a script consumes more time than the actual manual operations. This is where the thought process needs to be streamlined and improvised.
Get started using Python on Windows for scripting and automation
Think of the script as an infrastructural investment. Initially, it involves effort in setting up and learning to write. But it will be useful in the long game. Every time you put effort into writing a script, you have one less problem to worry about when the same use case arises.
These scripts when documented and stored together, will also help other engineers who face similar problems. Hence, though initial effort is necessary, scripting is beneficial in the long run and saves a lot of time. Python is a kind of programming language that can easily be learnt and used. It is a boon that such an easy language can be used to solve problems of high complexities and cloud automation. One need not know core concepts of the language to solve problems.
Boto library consists of a set of functions specific to AWS services which can be invoked to perform necessary cloud automation operations. The earlier version of boto was maintained by MIT. This version is more reliable as it is regularly updated by AWS and availability of descriptive documentation in one place. This can be achieved by creating a boto3 session using authentication credentials.
Hence it is very important to protect credentials and make sure that no outsider gets hold of your access key or secret key. Installation of boto3 can be done easily using the command pip install boto3.
Region can be configured as well if necessary. If there is no key value pair, you can generate one and use the same.
If no session is specified, boto3 uses the default session to connect with AWS and return a session object.IT administrators and DevOps engineers often perform routine operations to manage their cloud infrastructure and modern cloud workloads.
Such tasks are considered as Day-2 tasks as they generate routine outcomes for the organization. Customers often use Python scripts to perform such tasks. Creating and managing the required computing environment for Python scripts, along with ongoing administration overheads for security and traceability, is a growing challenge. Python scripts can be embedded in Automation Documents and executed without the need for additional compute resources.
Customers will need to enable required permissions and make documents available to each AWS Account and Region they would like to manage. Customers can easily upload and manage a catalog of Python scripts and convert scripts into reusable tasks. MontyCloud has also enabled a simple Role-Based Access Control model to securely enable self-service capabilities.
In just a few clicks, administrators can resolve issues and deliver efficient Day-2 operations. Customers like LeadSquared demand a high degree of automation in cloud operations and better efficiency in enabling modern DevOps. Before the launch of this feature, LeadSquared was creating and managing several Lambda functions to accomplish their goals.
LeadSquared also had to perform additional overhead tasks to centrally manage, provision, and secure custom Python scripts. To better manage their growing AWS Cloud infrastructure and mission-critical applications, LeadSquared was looking to improve the efficiency of their Day-2 operations. Typical Day-2 tasks performed by LeadSquared can be classified into the following three categories:. MontyCloud has empowered cloud IT teams in LeadSquared to perform operations in all these categories.
LeadSquared uses Amazon SQS queues in their distributed application to decouple tasks and execute units of work. Their application uses over queues and is provisioned to dynamically and horizontally scale. A routine task was performed to track every queue individually, and analyze their usage and performance throughout the day, taking over two hours to complete.
To optimize this operation, LeadSquared developed a Python script that pulls data from Amazon CloudWatch for querying multiple queues and aggregates the data. The script also analyzes the aggregated data and reports critical metrics that help assess performance of both individual queues and the overall application.
LeadSquared used MontyCloud to convert this script into a centrally managed task and made it available to multiple users in their environment. LeadSquared uses Amazon Aurora databases to power several critical cloud applications. When an application experiences performance issues, they create a clone of their Aurora DB on the AWS Management Console to perform analysis and develop fixes.
The traffic first traverses the firewall and then their network. A few months ago, due to an inadvertent configuration change, the tool malfunction, which caused a significant impact on LeadSquared, as their critical cloud applications were inaccessible. It took LeadSquared over 20 minutes to reroute traffic away from the firewall and directly to their network because this task had to be manually performed for each application. Since that incident, LeadSquared has designed a Python script that easily redirects traffic away from the firewall and directly to their network by modifying the DNS entries in Route Due to the critical nature of some tasks, IT administrators had to protect details of API endpoints and were unable to decentralize tasks.
