Do you prefer a terminal to manage your Kubernetes resources yet find yourself sometimes kubectl’ing a bit too much? There’s a new rising star in the K8s TUI space!

kty, dubbed “the terminal for Kubernetes” and written in Rust, was recently created to empower you with a console-based dashboard for interacting with K8s clusters via any SSH client (including the one you might have on your phone!). You will need to install it to your cluster in order to:

- Log in to your cluster via OpenID providers’ accounts, such as GitHub or Google;
- Navigate through your Kubernetes Pods and filter them (listing Nodes will be added soon);
- Check your Pods’ manifests, get a shell, read the logs;
- Forward traffic from your local machine to the cluster and vice versa;
- Transfer files from your Pods via SCP or SFTP.

The recent ISSTA (International Symposium on Software Testing and Analysis) 2024 conference featured a research article called “An Empirical Study on Kubernetes Operator Bugs”. Its authors conducted the first comprehensive study on 210 operator bugs from 36 Kubernetes operators, including those for PostgreSQL, MySQL, Redis, Elasticsearch, OpenTelemetry, Prometheus, etc.

Some of the findings are:
- The most common bug patterns in the K8s operators are incorrect state observation and analysis (60%), incorrect reconciliation (27%), incorrect custom resource definition (9%), and incorrect access control configuration (4%).
- 83% of operator bugs require updating specific state properties or updating them with specific values.
- 54% of operator bugs only lead to silent failures such as unstable state and undesired state.

Here comes our newest digest of the prominent software updates in the Cloud Native ecosystem!

Release Spotlight: CloudNativePG 1.24.0

CNPG is a Kubernetes operator for PostgreSQL databases. Last month, the project announced its new v1.24.0 release with significant updates. Perhaps the two most prominent features are Distributed PostgreSQL Topologies, which enable hybrid and multi-cloud CNPG deployments, and Managed Services, which allow advanced service management, including accessing PostgreSQL outside Kubernetes.

CNPG 1.24 also got an enhanced synchronous replication API with the synchronous_standby_names option, WAL disk space exhaustion prevention, declarative delayed replicas, transparent support for the allow_alter_system parameter (from PostgreSQL 17), an ability to define postInit and postInitTemplate instructions in configmaps or secrets, and more. You can find more information on GitHub.


Other noticeable updates in the Cloud Native space:

1. OpenTelemetry Collector v0.109.0 with an updated GitHub Receiver (previously known as Git Provider Receiver) adhering to the CICD Semantic Conventions 1.27.0 and GitHub metrics promoted to alpha. Other new features include a receiver for Google Cloud monitoring, support for Prometheus-created timestamps, exponential histogram support for Elasticsearch, encoding extensions in the Kafka receiver, and more.

2. CRI-O, an OCI-based implementation of Kubernetes Container Runtime Interface (a graduated CNCF project), was updated to v1.31.0 with crun as the default OCI runtime. It also got support for fine-grained SupplementalGroups control and Kubernetes image volume source (both appeared in Kubernetes v1.31), sigstore signature verification for policies corresponding to a certain Kubernetes namespace, new --no-sync-log option, new crio check subcommand, etc.

3. Jaeger, a distributed tracing system (a graduated CNCF project), is getting closer to its v2 with v1.61.0 / v2.0.0-rc1. Jaeger v2 introduces a new architecture for Jaeger backend components based on the OpenTelemetry Collector framework. You can read more about it in this article. The latest release also brought numerous experimental features, such as validation in badger storage and memory storage configs, tail-based sampling processor extension, and health check extension.

4. Argo CD v2.13 RC was announced with 40+ new features. They include a new argocd appset generate command to preview application manifests, a dry-run mode for argocd appset create, promotion of the multi-source applications from beta to stable, an ability to use regexps to configure the allowed namespaces, improved reconcile performance for applications with many resources, added Application Set metrics, and more.

5. KCL, a constraint-based record and functional language (a CNCF Sandbox project), released its v0.10.0 with numerous changes in the core, toolchain, IDE, libraries, and SDKs. Some of them are attribute access and index access in assignment statements, a new kcl test tool, a new KCL C/C++ language SDK, KCL WASM lib support for Mode.js and browser integration.

Here goes our latest bunch of interesting Kubernetes-related articles recently spotted online:

1. “Kubernetes security fundamentals: Admission Control” by Rory McCune, Datadog.

“In this post we'll take a look at admission control, another key aspect of Kubernetes security. Admission control is the last of the three stages that requests go through when they're being processed by a Kubernetes cluster. Assuming that the request has valid credentials and is authorized, Kubernetes admission controllers will process the request and may modify or reject it during that process.”

2. “High Availability Alertmanager on Kubernetes: No Alerts Left Behind” by Joe Banks.

“For alerting in Python Discord and other personal projects I am a big fan of AlertManager. Unlike other much more complex alerting and on-call systems, AlertManager is a dead-simple Go application which is easy to deploy and configured solely with YAML files. [..] This article covers my approach to making AlertManager highly available on Kubernetes, and how you can do the same.”

3. “Developer's Guide to Installing OpenTelemetry Collector” by Prathamesh Sonpatki, Last9.

“Learn how to install and configure the OpenTelemetry Collector for enhanced observability. This guide covers Docker, Kubernetes, and Linux installations with step-by-step instructions and configuration examples.”

4. “Using GitHub as a Helm Chart Repository” by Christian Huth.

“GitHub Pages in combination with the GitHub Releaser Action make it really easy to publish your Helm Charts securely and reliably. You can use a custom domain to change the default domain to suit your needs and make the Helm Repository easily accessible. [..] In this guide, I'll show you how to set up a Helm Chart Repository in less than 10 minutes using GitHub Pages and GitHub Action Workflows.”

5. “Securing Kubernetes and Containers: Best Practices to Reduce Attack Surface” by Nathan Hueck.

“By following these best practices for securing Kubernetes and Containers in cloud environments, you can significantly reduce the attack surface and ensure that your containerised workloads are protected from common security threats. [..] Secure the Kubernetes API; Secure the Kubelet; Pod Security; Network Security; Secrets Management; Image Security; Monitoring and Logging; Regular Patching and Updates; Auditing Kubernetes; Additionally Securing Containers.”

EDB, the original authors of CloudNativePG, celebrates the leadership of its well-known Kubernetes operator for PostgreSQL in GitHub stars. The project was launched just two years ago, and now it has surpassed all other Open Source PgSQL operators in stargazers.

This happened just recently: at the time of writing this post, CNPG had 4291 stars vs. 4264 for its closest opponent (an operator from Zalando). Also, as we all know, GitHub stars are quite a vague metric. However, the star history chart confirms an overall trend in how the community adopts CNPG.

P.S. Here, you can find an overview of CNPG and a brief comparison with other solutions.

Here comes our newest digest of the prominent software updates in the Cloud Native ecosystem!

1. Cortex, a scalable long-term storage for Prometheus (a CNCF Incubating project), got its v1.18.0 with lots of updates. They include an experimental native histogram ingestion, support for filtering alerts (ListRules API), new query rejection mechanism, a token bucket limiter, and ingester metadata API limits.

2. Argo Workflows, a workflow engine for orchestrating parallel jobs on Kubernetes, has seen its v3.6.0-rc1 with hundreds(!) of changes. Some of its new features are using Prometheus TLS by default, configurable individual metrics, OpenTelemetry metrics and numerous new other metrics (Pod pending counter, Pod phase counter, leader metric, etc.), multiple schedules in CronWorkflow, SQLite-based memory store for live workflows, dynamic templateRef naming, support for ephemeral credentials for S3, and many UI improvements.

3. Kanister, a framework for application-level data management on K8s (a CNCF Sandbox project), released v0.111.0 with support for read-only and write access modes when kando connects to Kopia repository server, cache size limits for Kopia server, an ability to pass labels and annotations when creating/cloning volume snapshot resources, and customisation of the labels and annotations of the temporary Pods created by Kanister.

4. Kata Containers 3.9.0 introduced support for pulling cosign-signed images, refined device management for kata-agent, image annotations for remote hypervisors, SetPolicy support in agent-ctl, and more.

5. Devtron, a tool integration platform for Kubernetes, was updated to v0.7.2. This release brought support for creating plugins at pipeline stage level, TLS support for Git and GitOps, GitOps support for OCI repositories, GitLab webhook support, async Argo CD app refresh operation, and other features.

6. PipeCD, a GitOps-style continuous delivery platform for apps across different environments (a CNCF Sandbox project), got its v0.49.0 featuring significantly improved AWS Lambda support (plan preview, drift detection, etc.), ECS enhancements (drift detection, LiveState UI), OIDC support for the SSO, and sending OpenTelemetry traces to control plane.

Our newest bunch of interesting Kubernetes-related articles recently spotted online:

1. “The Beginner's Guide to Securing Kubernetes” by Ophir Kelmen, Hunters.

“In this article, you will learn foundational terms and concepts essential for securing Kubernetes clusters. Whether you're a beginner or an experienced professional, this guide covers the critical knowledge required to understand the security dimensions of Kubernetes and methods to identify and detect specific attack techniques. No prior knowledge of Kubernetes is necessary to benefit from the article.”

2. “OpenTelemetry Tracing in 200 lines of code” by Jeremy Morrell.

“It’s no wonder then that most developers approach tracing libraries as unknownable black boxes. We add them to our applications, cross our fingers, and hope they give us useful information when the pager goes off at 2am. They are likely a lot simpler than you expect! Once you peel back the layers, I find a useful mental model of tracing looks like “fancy logging” combined with “context propagation” a.k.a “passing some IDs around”.”

3. “The Istio Service Mesh for People Who Have Stuff to Do” by Luca Cavallin.

“Istio is a powerful tool that simplifies traffic management, security, and observability for microservices. Contributing to Istio gave me insight into how it helps solve some of the complex challenges that come with running distributed systems. If you're running a microservices architecture or planning to scale, Istio can help you make your system more resilient and easier to manage.”

4. “Node.js 20 upgrade: a journey through unexpected HEAP issues with Kubernetes” by Loïc “Ztec” Doubinine, Deezer.

“When using Node.js in a Kubernetes environment, and more broadly in a containerized scenario, you must consider the memory and CPU reservation. It needs to be configured in order to set limits to your process that would otherwise consume more than you expected. Also, setting it to low values requires attention to ensure the process accommodates the limit appropriately.”

5. “Introduction to the Gateway API: Revolutionizing Kubernetes Networking” by Disha Virk.

“Traditional tools like the Ingress API have long been the backbone for exposing services to external traffic, but as environments grow more sophisticated, developers and operators are looking for greater flexibility, extensibility, and fine-grained control over network traffic. In this article, we’ll dive deep into what the Gateway API is, why it was developed, and how it’s set to transform the way we handle networking in Kubernetes.”

6. “Keycloak with istio and Oauth2-Proxy” by Chris Haessig.

“Setting up Istio with Keycloak and OAuth2 Proxy is a common pattern for adding authentication and authorization to your microservices architecture. Each component plays a crucial role in securing access to resources while maintaining flexibility and scalability. Keycloak acts as an identity provider (IdP) and OAuth2 authorization server. It manages user authentication, including multi-factor authentication (MFA), single sign-on (SSO), and federation. By integrating OAuth2 Proxy, you can convert the OAuth2 authentication flow from Keycloak into HTTP headers that are passed to backend services. This decouples services from handling authentication logic, allowing centralized security management.”

I’ve explored the value it brings and found that, in the end, many solutions share a similar logic."

6. "The Karpenter Effect: Redefining Our Kubernetes Operations" by Tanat Lokejaroenlarb, Adevinta.

"Managing a fleet of over 2,000 Kubernetes nodes and 30 clusters across 25 marketplaces is no small feat. While using Kubernetes Cluster Autoscaler and Amazon EKS Managed Node Groups served us well initially, we began encountering operational hurdles that hampered our efficiency and scalability. The complexities of cluster upgrades, the rigidity in instance type selection and limitations in use-case flexibility were becoming increasingly burdensome. We needed a solution that could address these challenges head-on."

Stefan Prodan, a core maintainer of Flux, announced Flux Operator in the ControlPlane blog.

This project is described as “a new component in the Flux CD ecosystem that automates the lifecycle management of Flux components and streamlines GitOps workflows for Kubernetes clusters.” Technically, it works as a Kubernetes operator (CRD controller), which can be used (instead of flux bootstrap) to deploy Flux and manage it in your cluster. This approach strives to simplify the installation, configuration, and operation (e.g., upgrading, scaling, and improved observability) of Flux. The operator's code is written in Go and licensed under AGPL 3.0.

Operators became an essential part of the Kubernetes ecosystem. There are hundreds of operators today, and you can find most of them at OperatorHub. Interestingly, there is another way to discover them, especially the most popular ones.

awesome-operators repo on GitHub lists 300+ Kubernetes operators and:

1. sorts them by GitHub stars;
2. dismisses the projects with no updates in the last 6 months.

… which proves to be quite useful! The only visible downside is that little additional information on each operator is provided (e.g., no categorisation).
