Possible disadvantages of iTerm2

    iTerm2 is exclusive to macOS, which means users on other operating systems cannot utilize its features.
  • Complexity
    The sheer number of features and customization options can be overwhelming for beginners, requiring a learning curve to utilize efficiently.
  • System Resource Usage
    iTerm2 may consume more system resources compared to simpler terminal emulators, which could be a concern on lower-end hardware.
  • Update Frequency
    Occasional updates can introduce bugs or unexpected behavior, requiring users to adjust settings or find workarounds.

Packer features and specs

  • Multi-Provider Support
    Packer supports a wide variety of providers such as AWS, Azure, Google Cloud, VMware, and more. This allows for flexibility and the ability to create machine images across different environments.
  • Automation
    Packer automates the creation of machine images, eliminating the need for manual image configuration and reducing the potential for human error.
  • Script Reusability
    Packer allows for the reuse of scripts and configuration files, enabling a consistent and repeatable process for image creation.
  • Parallel Builds
    Packer can build multiple images in parallel, which can significantly speed up the provisioning process.
  • Idempotency
    Packer ensures that the output machine image is always an identical result given the same input configuration, reducing the risk of inconsistencies.

Possible disadvantages of Packer

  • Steep Learning Curve
    The variety of features and flexibility that Packer offers can make it complex and challenging to learn, especially for beginners.
  • Limited Debugging Tools
    Packer's debugging tools are not as mature or as integrated as those found in some other DevOps tools, making troubleshooting more difficult.
  • Configuration Complexity
    Complex configurations with multiple builders and provisioners can become hard to manage and maintain, leading to potential errors.
  • No State Management
    Unlike Terraform, Packer does not manage state, which means users need to handle state management separately if required.
  • Dependency on External Tools
    Packer often relies on external scripts and tools for provisioning, which can introduce additional dependencies and complexities.

  • Failed to connect to the host via SSH on Ubuntu 22.04
    If you have just upgraded to Ubuntu 22.04, and you suddenly experience either errors when trying to ssh into hosts, or when running ansible or again when running the ansible provisioner building a packer image, this is probably going to be useful for you. - Source: dev.to / almost 4 years ago
  • Create a minimalist OS using Docker Containers and Hashicorp Packer
    I am already using Hashicorp Packer at work and for personal projects and I wanted to test This idea out by wrapping it a single Packer Template file. This reduces the level of maintaining a lot of small scripts, Dockerfiles and configurations and the user can simply trigger a couple of Commands to get a minimalist OS at the end of the process. - Source: dev.to / almost 4 years ago
  • After self-hosting my email for twenty-three years I have thrown in the towel. The oligopoly has won.
    And while it is a slight increase in complexity, it can be an overall net gain in functionality, configurability and reliability. Much like Packer is far more reliable and practical than manually making VM images sitting in front of a terminal, even though making the initial configuration takes some time.

  • Customized Ubuntu Images using Packer + QEMU + Cloud-Init & UEFI bootloading
    Hashicorp Packer provides a nice wrapper / abstraction over the QEMU in order to boot the image and use it to set it up on first-boot. Instead of writing really long commands in order to boot up the image using QEMU, Packer provided a nice Configuration Template in a more Readable fashion. - Source: dev.to / almost 4 years ago
  • The journey of sharing a wired USB printer over the network
    Packer seemed like the perfect tool for the job. I have never used it before and wanted to get familiar with the tool. It doesn't come with ARM support out of the box, but there are two community projects to fill that niche. - Source: dev.to / over 4 years ago
