• Configure the Amazon Linux 2 MATE desktop connection - Amazon Elastic Compute Cloud

  • Follow these steps to set up a Remote Desktop Protocol (RDP) connection from your local machine to an   Amazon Linux 2 instance running the MATE desktop environment.
  • Reconnect to the instance and run the following command on your Linux instance   to set the password for ec2-user.

• Xrdp - ArchWiki

  • First, start the xrdp service. You should be able to connect an RDP client to the host on the default RDP port (3389). If successful, you will be greeted with the xrdp session manager window which allows you to choose between Xorg or Xvnc sessions and provides inputs for user authentication. The session manager UI can be highly customized by modifying /etc/xrdp/xrdp.ini. 

    The parameters used to start Xorg and Xvnc display servers can be configured in /etc/xrdp/sesman.ini. 

    After successfully starting a display server, xrdp will execute /etc/xrdp/startwm.sh by default. This script is meant to start a window manager (similar to .xinitrc) and will read from ~/.xinitrc or /etc/X11/xinit/xinitrc if they exist. It is recommended to edit ~/.xinitrc to start your desktop environment or window manager, but you can also edit /etc/xrdp/startwm.sh. 

    If you just close the session window and RDP connection, you can access the same session again next time you connect with RDP. When you exit the window manager or desktop environment from the session window, the session will close and a new session will be opened the next time.

• Provider Requirements - Configuration Language | Terraform | HashiCorp Developer

  • The required_providers block must be nested inside the top-level terraform block (which can also contain other settings).
  • Each module should at least declare the minimum provider version it is known to work with, using the >= version constraint syntax:

• Use xrdp with Linux - Azure Virtual Machines | Microsoft Learn

  • If you created a password for your user account when you created your VM, skip this step. If you only use SSH key authentication and don't have a local account password set, specify a password before you use xrdp to log in to your VM. xrdp can't accept SSH keys for authentication. The following example specifies a password for the user account azureuser:
  • Specifying a password does not update your SSHD configuration to permit password logins if it currently does not. From a security perspective, you may wish to connect to your VM with an SSH tunnel using key-based authentication and then connect to xrdp.

• What are Terraform Workspaces? Overview with Examples

  • In this example, I have used the AWS S3 bucket as the remote backend.
  • When we look at the contents of the Terraform state S3 bucket, apart from our default terraform.tfstate file, we can see that a new directory named “env:/” is created, within which another directory with the name of our workspace (test_workspace) is created. A new terraform.tfstate file is maintained at this location.

  • Looking closely, the size of the default state file is considerably larger than that of the custom workspace-specific state file. This shows that the new state file is created, but it does not hold any information from the default state file. This is how Terraform creates an isolated environment and maintains its state file differently.

     

    The contents of the test_workspace state file before running terraform apply are shown below:

• Understand ‘terraform plan/apply -refresh-only’ (formerly ‘terraform refresh’) and fixing drift | by Soon Hin Khor, Ph.D. | Code Oil | Medium

  • When you practice infrastructure-as-code (IaC), e.g., using terraform, there are 3 types of “infrastructure state”

    • “infrastructure state described by the terraform DSL (Domain Specific-Language) configuration files”: This is the outcome of a devops codifying the infrastructure in a bunch of files
    • “actual infrastructure state”: This is the actual infrastructure, which is the result of using terraform to deploy the infrastructure codified in the “terraform DSL configuration files” from the previous step
    • “terraform state file”: This an artifact generated by the terraform deployment. It holds information that is otherwise not available anywhere else; it maps the infrastructure components codified in the “terraform DSL configuration files” to the actual manifested infrastructure components. This is usually stored in central store, e.g., AWS S3, etc., accessible to all terraform users so that everyone sees the same state, and it can be locked to prevent simultaneous changes, to avoid state corruption.

• WSL Page - Feature Exploration! · Issue #2266 · microsoft/devhome

  • Nice.

     

    But there existing more solutions then "Raft". I have none of them tested.

     

    For example

     
     
    • eaysWSL https://github.com/redcode-labs/easyWSL
     
    • WSL2 Distro Manager https://github.com/bostrot/wsl2-distro-manager
     
    • WSL ToolBox https://github.com/FalconNL93/WslToolbox
     
    • .. etc
     
     

    But I think, that a WSL-developer could created a better integrated GUI, which is more then only a frontend of an command line program. For example, like in the mockup shown, something to show the used memory and CPU-usage of every VM. Possible in an graph like the TaskManger doing it for the complete computer.

• Debugging | Terraform | HashiCorp Developer

  • Note that even when TF_LOG_PATH is set, TF_LOG must be set in order for any logging to be enabled.

• What does terraform apply/plan refresh-only do? - Stack Overflow

  • For all terraform commands that involves states, e.g., plan, apply, refresh (deprecated and is now '-refresh-only'), it is useful to think about it in terms of 2 things:

     
     
    • The authoritative state
     
    • The states being compared Note that the 'authoritative state' is NEVER changed as a result of the command.
     
     

    There are 3 types of 'state' (loosely):

     
     
    • Actual state of your infra (actual-state)
     
    • terraform state file (tf-state-file)
     
    • State described by terraform code config (tf-dsl-config)
     
     

    When you do terraform plan/apply WITH -refresh-only:

     
     
    • The authoritative state is 'actual-state'
     
    • The states being compared in 'terraform plan -refresh-only' is 'actual-state' vs. 'tf-state-file'
     
    • The outcome of 'terraform apply -refresh-only' is 'tf-state-file' is synced to become 'actual-state'
     
     

    When you do terraform plan/apply WITHOUT -refresh-only:

     
     
    • The authoritative state is 'tf-dsl-config'
     
    • The states being compared in 'terraform plan' is 'tf-dsl-config' vs. 'actual-state'
     
    • The outcome of 'terraform apply' is 'actual-state' is synced to become 'tf-dsl-config'
     
     

    For more details of what authoritative states are, and what states are being compared for various terraform commands see:

• Amazon OpenSearch Service’s vector database capabilities explained | AWS Big Data Blog

  • RAG is a method for building trustworthy generative AI chatbots using generative LLMs like OpenAI, ChatGPT, or Amazon Titan Text. With the rise of generative LLMs, application developers are looking for ways to take advantage of this innovative technology. One popular use case involves delivering conversational experiences through intelligent agents. Perhaps you’re a software provider with knowledge bases for product information, customer self-service, or industry domain knowledge like tax reporting rules or medical information about diseases and treatments. A conversational search experience provides an intuitive interface for users to sift through information through dialog and Q&A. Generative LLMs on their own are prone to hallucinations—a situation where the model generates a believable but factually incorrect response. RAG solves this problem by complementing generative LLMs with an external knowledge base that is typically built using a vector database hydrated with vector-encoded knowledge articles.

• Ultimate Guide to Terraform: From Beginner to Expert — Zero to Devops

  • Ansible, Chef and Puppet are configuration management tools which means they are primarily designed to install and manage software on existing server
  • In Terraform there are certain providers that are either "Hashicorp Maintained" (AWS, Azure etc.) or "Non-Hashicorp Maintained". Below is best practice syntax for establishing providers in your Terraform, notice how there are two blocks, one for what providers are required and another for each provider specific config.
  • Terraform Variables Basics
  • Local Values

    Local values assign a name to an expression, allowing it to be used multiple times within a module without repeating it.
  • Load Order and File Structure
  • Dynamic Blocks
  • Notice how we define the iterator as port now instead of being ingress.value it is port.value. This can make dynamic blocks easier to read and understand.
  • What if you want multiple different dynamic values in one dynamic block?
  • Variables and Terraform Modules
  • Terraform Remote Backend
  • With one shared state file every time an apply is done the state file is locked so two apply processes can not be run at the same time.

    Using a remote backend for state files is the recommended process for collaborative environments. Nearly all businesses using Terraform use remote backend for state files.

• An Introduction to Terraform. Learn the basics of Terraform in this… | by Yevgeniy Brikman | Gruntwork

  • Adding a data source to your Terraform configurations does not create anything new; it’s just a way to query the provider’s APIs for data and to make that data available to the rest of your Terraform code. Each Terraform provider exposes a variety of data sources. For example, the AWS Provider includes data sources to look up VPC data, subnet data, AMI IDs, IP address ranges, the current user’s identity, and much more.
  • With the aws_vpc data source, the only filter you need is default = true
