Project mention: Best Open Source Monitoring Tools in 2026: 7 Self-Hosted Options Compared | dev.to | 2026-06-13
Netdata is a real-time infrastructure monitoring agent that collects metrics at per-second granularity with near-zero configuration. Install the agent on a server, and within seconds you have 2,000+ metrics being collected — CPU, memory, disk I/O, network, processes, containers, and hundreds of application-specific collectors. The level of instant visibility is unmatched.

Moby
The Moby Project - a collaborative project for the container ecosystem to assemble container-based systems
Project mention: exec /entrypoint.sh: no such file or directory? Fix CRLF line endings, shebangs and chmod before Docker runs | dev.to | 2026-10-08The missing file is the interpreter, but the message names your script. The usual source is a Windows checkout with core.autocrlf=true: docker build sends that CRLF working tree, and COPY puts it in the image (real example, Moby's request for a better error).

trivy

Project mention: Rootless podman export of a keep-id container shifts every file owner, exit 0 | dev.to | 2026-09-29
TL;DR: podman export of a rootless container that was created with --userns=keep-id writes a tarball in which every file owner is shifted by the container's ID mapping. Inside the container the user's home is 1000/1000 and system files are 0/0. In the export, the home is 0/0, the 3257 root-owned files are 1/1, and su, passwd and the other setuid binaries are setuid to UID 1. The export exits 0 and prints nothing. Import that tarball and the user can't write to its own home directory. podman cp ctr:/ - produced the same shift. podman commit maps the owners back: commit the container, create a plain container from the image, and export that. The export code passes no ID mapping to its tar writer, in 5.4.2 and in current main. Reproduced on a Raspberry Pi with Debian's podman 5.4.2. The toolkit's check-podman-export-idmap.sh lists the containers at risk and checks an export without writing it. Upstream report: podman-container-tools/podman#29856.

Project mention: Self-hosted PaaS in 2026: Coolify vs Dokku vs CapRover vs Ownkube | dev.to | 2026-09-13
This post compares the four self-hosted and "self-hosted-style" PaaS options we see startups evaluating most often: Coolify, Dokku, CapRover, and Ownkube. We'll cover what each one is, who it fits, where the ceiling is, and the honest tradeoffs. If you're trying to leave Heroku specifically, our Heroku alternative guide covers the workflow translation in more detail.

Project mention: The brew services Setup That Finally Got Docker Desktop Off My Mac (and Made Local Postgres Feel Instant) | dev.to | 2026-08-02
And yes, I did the responsible thing and evaluated the usual Docker Desktop alternatives first. Colima, OrbStack, and Podman are all genuinely lighter than Docker Desktop and worth knowing - Colima especially gives you a Docker-compatible runtime with minimal fuss. But they're still containers. They shave the licensing and some of the RAM; they don't change the fundamental fact that you're running a Linux VM to host a database your Mac can run natively. For a single local Postgres or Redis, brew services isn't a lighter container runtime. It's no container at all - which is the part most "Docker Desktop alternatives 2025" roundups quietly skip.

Project mention: War Story: Debugging a Kafka 4.0 Consumer Lag Spike During a Product Launch Using Cilium 1.17 and Datadog 2026 | dev.to | 2026-04-28
This adds less than 2% overhead to your node’s CPU usage but exposes 14 Kafka-specific eBPF metrics that are critical for debugging lag. We’ve found that 72% of Kafka 4.0 lag incidents we’ve responded to in 2026 stem from node-level network policy issues that only eBPF can detect. If you’re using a different CNI, you can still use Cilium’s standalone eBPF probe https://github.com/cilium/cilium/tree/v1.17.2/contrib/kafka-probe to get these metrics without replacing your entire CNI. Always validate that kafka.heartbeat_drops_total is 0 in staging before every launch.

As far as I know, Firecracker, gVisor, and Kata Containers are the solution here. They use VM primitives (x64_64 and ARM64 extensions) and have lighter codebases
https://firecracker-microvm.github.io/
https://gvisor.dev/
https://katacontainers.io/
But I don't have any direct experience with any of them. I'd be curious what people who have built on top of them think

Project mention: Arc Tideline: ephemeral GitHub Actions runners powered by Karpenter | dev.to | 2026-06-17
I was used to employ Google Skaffold, but often I felt it lacked flexibility in expression, so I have rather used Devspace, an open-source dev tool for Kubernetes.

Project mention: Container Technology Explained: How Docker and OCI Containers Work | dev.to | 2026-03-15
Previously, Docker used lxc, but from v0.9, it seems to use libcontainer implemented in Go. (cf. Docker blog - DOCKER 0.9: INTRODUCING EXECUTION DRIVERS AND LIBCONTAINER github - opencontainers/runc/libcontainer/)
