k3s features and specs

  • Lightweight
    K3s is designed to be lightweight and less resource-intensive compared to full Kubernetes distributions, making it ideal for edge and IoT devices, as well as development environments.
  • Easy Installation
    K3s provides a simple installation process, requiring only a single binary for installation, which simplifies the setup procedure for users.
  • Low Resource Usage
    By stripping away non-essential features, K3s consumes significantly fewer resources, lowering the barrier to entry for running Kubernetes on resource-constrained environments.
  • Fully CNCF Conformant
    K3s is certified by the Cloud Native Computing Foundation (CNCF) as conformant with standard Kubernetes, meaning it follows the same API and operational model.
  • Built-In Database
    K3s includes an embedded SQLite database by default, which simplifies deployment and reduces the complexity associated with managing an external etcd cluster.
  • Automated TLS Management
    K3s has integrated support for TLS certificates management, which helps in ensuring secure communications between components without additional configuration.
  • Ecosystem Compatibility
    K3s supports popular Kubernetes add-ons and CI/CD tools, so it can be seamlessly integrated into existing Kubernetes-based workflows.

Possible disadvantages of k3s

  • Reduced Feature Set
    To keep K3s lightweight, some non-essential Kubernetes features and components are omitted or replaced, which might limit functionality for more advanced use cases.
  • Lack of Scalability
    K3s is optimized for smaller clusters and edge environments, so it may not scale as efficiently as standard Kubernetes distributions in large, enterprise-level deployments.
  • Embedded SQLite Limitations
    While the built-in SQLite database simplifies initial setup, it may not handle high write loads or offer the same reliability and performance as an external etcd cluster for production environments.
  • Community and Enterprise Support
    Although supported by the Kubernetes community, K3s may have less enterprise-grade support and fewer educational resources compared to other full-featured Kubernetes distributions.
  • Ecosystem Integration
    Certain Kubernetes tools or cloud services optimized for full Kubernetes distributions may not work seamlessly with K3s, requiring custom configurations or workarounds.
  • Limited Networking Options
    K3s might have fewer networking configuration options compared to full-featured Kubernetes implementations, potentially restricting advanced network setup.
  • Simplified Security Model
    K3s implements a simplified security model which might lack some advanced security features and policies found in the standard Kubernetes distribution.

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.

  • 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 / 19 days ago
  • Kubernetes testing w/ Dagger.io
    What we need is a way to bootstrap a Kubernetes Cluster itself. Being in a docker-like environment the best option is a Kubernetes in Docker solution, Such as KinD or K3s. Both are available in Daggerverse and can be installed as external module to be reused. - Source: dev.to / about 2 months ago
  • How I Cut Our GitHub Actions Pipeline Time by More Than 50%
    Before landing on the base image approach, my first assumption was that the Kubernetes cluster setup was the bottleneck - we use kind to run dependencies like PostgreSQL and NATS. I replaced kind with k3s. It saved 1โ€“2 minutes, but nothing significant on its own. - Source: dev.to / 3 months ago
  • Docker Compose vs Kubernetes: Secure Homelab Choices
    I use K3s specifically because full Kubernetes is absurd for a homelab. K3s strips out the cloud-provider bloat and runs the control plane in a single binary. My cluster runs on a box with 32GB RAM โ€” plenty for ~40 pods. - Source: dev.to / 3 months ago
  • Stop babysitting your AI agent!
    NVIDIA seems to agree. Their OpenShell project takes the same approach: sandboxed execution environments with declarative YAML policies governing egress, filesystem access, and credentials. It uses containers (K3s under the hood) as the isolation boundary. - Source: dev.to / 3 months ago

  • Show HN: SQL-tap โ€“ 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 / 5 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 / 11 months 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 / about 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 / about 3 years ago
