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.

StackGres features and specs

  • Integrated PostgreSQL Management
    StackGres provides a comprehensive suite for managing PostgreSQL clusters, simplifying configuration, deployment, and maintenance.
  • Scalability
    StackGres supports dynamic scaling of PostgreSQL clusters, allowing for flexible resource allocation based on workload demands.
  • Kubernetes Native
    Built on Kubernetes, StackGres leverages its powerful orchestration capabilities for high availability and container management.
  • Security Features
    Includes advanced security features like SSL/TLS, authentication, and role-based access control to safeguard data and connections.
  • Monitoring and Alerting
    Comes with integrated monitoring and alerting tools, providing insights into database performance and health metrics.

Possible disadvantages of StackGres

  • Complexity
    The Kubernetes-based environment can introduce complexity for users unfamiliar with container orchestration and management.
  • Resource Intensive
    Running StackGres requires significant computational resources, which might be overkill for small-scale or less demanding applications.
  • Learning Curve
    New users may face a steep learning curve in mastering StackGres for effective management of PostgreSQL in a Kubernetes environment.
  • Cost Considerations
    While powerful, using Kubernetes and associated resources for StackGres can lead to higher operational costs.
  • Dependency on Kubernetes
    Requires a functional Kubernetes cluster, which might be a barrier for organizations not currently using Kubernetes.

Introduction to Top Open Source Virtualization Tools
Packer is notably light, high performing, and operates on every major operating system. It assembles and configures all the necessary components for a virtual machine then creates images that run on multiple platforms. Packer doesn’t replace configuration management tools like Puppet or Chef; as a matter of fact, when creating images, Packer can utilize tools like Puppet or...

  • 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 / about 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

  • TimescaleDB compresses time-series data
    At StackGres [1] we find Timescale to be one of the most used extensions. Timescale is quite a successful project! StackGres is actually the first solution recommended by Timescale for self-hosting with Kubernetes operators [2]. So if you are into Kubernetes (or if not, consider it, using something like K3s [3] is quite straightforward and lightweight on resources), this is probably a great option to self-host... - Source: Hacker News / 3 months ago
  • Show HN: SQL-tap – Real-time SQL traffic viewer for PostgreSQL and MySQL
    * Latency. Yes, yes, yes, they add "microseconds" vs "milliseconds for queries", and that's true, but just part of the story. There's an extra hop. There's two extra sets of TCP layers being traversed. If the hop is local (say a sidecar, as we do in StackGres) it adds complexity in its deployment and management (something we solved by automation, but was an extra problem to solve) and consumes resources. If it's a... - Source: Hacker News / 7 months ago
  • Application Less Containers
    This is conceptually similar to what we did for Postgres extensions at the StackGres [1] project. I gave a talk at a Kubecon about it [2]. However, this scheme is not perfect. Some Kubernetes security solutions enforce immutable containers, and once the agent pulls any additional file into the container, it will be flagged. It's also harder to reason about the security of the image (think CVEs, etc), given that... - Source: Hacker News / about 1 year ago
  • Pg_lakehouse: Query Any Data Lake from Postgres
    I applaud the decision to use AGPL-3.0. For me, it's a license that provides forward guarantees to the Community: no proprietary forks can happen, so any fork will be an OSS fork from which the upstream project may benefit too, which benefits all users. That's the reason we chose this license for StackGres [1], another project in the Postgres space. [1]: https://stackgres.io. - Source: Hacker News / over 2 years ago
  • Keycloak with PostgreSQL on Kubernetes
    This is good and interesting recipe to get Keycloak and Postgres on Kubernetes. There is an important improvement, though: the Postgres deployed here is not production ready (high availability, backups, monitoring, etc). We run Keycloak on StackGres [1] which gives us production-ready Postgres setup (disclaimer: it's dogfooding). Happy to share the YAML manifests used to deploy Keycloak with StackGres. Maybe we... - Source: Hacker News / over 3 years ago
