Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.

Was learning Go hard for you?
Though I am thinking of converting my Python Bolt slackbot (very early in development anyway) over to using slack-go. Mainly wanted to rewrite some of it anyway and use socket-mode.

Go team: honesty is the best policy?
code looks to be BSD licensed from https://github.com/slack-go/slack/blob/5a6b1b08ff8fa911e85bd582de643f7f0df0f0fb/chat.go

Is there any crate to work with Slack in Rust and how to approach library/crate creation for third-party vendors like Slack/GCP?
I have created a Slack bot that acts on some slack events to create Jira tickets using Slack Go. It was a hobby project for me but it's being used for some teams on my company.

2.7 - 83 issues closed
I have also tried to do this in Go, because I always would try to do something in Go given the opportinity, but the Go Slack API was using the outdated auth system, there was simply no documentation to follow at all. I see this in my second attempt at using Go, having no tools to use, or no instruction to follow. Oh well, maybe the next project...

Creating a flexible Backoffice Tool in a Technical Company using Slack
We use this library github.com/slack-go/slack for the API calls and data model.

Sending Slack Messages with Images using Go
The Slack Go SDK is a community SDK and not officially maintained by Slack. This means it doesn't get the same care or attention in terms of documentation and code examples.

Parsing a Slack-Go socket mode response
I am using Slack-Go (https://github.com/slack-go/slack) to create a modal to allow my users to enter some information.

Trying to build a Slack Bot in Go but can't figure out how to work with the Events API
Does the example in the repository for the Events API not useful? https://github.com/slack-go/slack/blob/master/examples/eventsapi/events.go

Handler and Middleware design pattern in Golang
I came across the well-maintained slack-go library; I started coding my bot using the provided example. Everything worked fine; The code is producing the expected result. It is time to make another coffee and implements a few extra features.

IBM to buy HashiCorp in $6.4B deal
> was always told early on that although they supported vault on kubernetes via a helm chart, they did not recommend using it on anything but EC2 instances (because of "security" which never really made sense their reasoning).
The reasoning is basically that there are some security and isolation guarantees you don't get in Kubernetes that you do get on bare metal or (to a somewhat lesser extent) in VMs.
In particular for Kubernetes, Vault wants to run as a non-root user and set the IPC_LOCK capability when it starts to prevent its memory from being swapped to disk. While in Docker you can directly enable this by adding capabilities when you launch the container, Kubernetes has an issue because of the way it handles non-root container users specified in a pod manifest, detailed in a (long-dormant) KEP: https://github.com/kubernetes/enhancements/blob/master/keps/... (tl;dr: Kubernetes runs the container process as root, with the specified capabilities added, but then switches it to the non-root UID, which causes the explicitly-added capabilities to be dropped).
You can work around this by rebuilding the container and setting the capability directly on the binary, but the upstream build of the binary and the one in the container image don't come with that set (because the user should set it at runtime if running the container image directly, and the systemd unit sets it via systemd if running as a systemd service, so there's no need to do that except for working around Kubernetes' ambient-capability issue).
> It always surprised me how these conversations went. "Well we don't really recommend kubernetes so we won't support (feature)."

Exploring cgroups v2 and MemoryQoS With EKS and Bottlerocket
0 is not the request we've defined. And that makes sense. Memory QoS has been in alpha since Kubernetes 1.22 (August 2021) and according to the KEP data was still in alpha as of 1.27.

Jenkins Agents On Kubernetes
Note: There's actually a Structured Authentication Config established via KEP-3331. It's in v1.28 as a feature flag gated option and removes the limitation of only having one OIDC provider. I may look into doing an article on it, but for now I'll deal with the issue in a manner that should work even with a bit older versions versions of Kubernetes.

Isint release cycle becoming a bit crazy with monthly releases and deprecations ?
Kubernetes supports a skew policy of n+2 between API server and kubelet. This means if your CP and DP are both on 1.20, you could upgrade your control plane twice (1.20 -> 1.21 -> 1.22) before you need to upgrade your data plane. And when it comes time to upgrade your data plane you can jump from 1.20 to 1.22 to minimize update churn. In the future, this skew will be opened to n+3 https://github.com/kubernetes/enhancements/tree/master/keps/sig-architecture/3935-oldest-node-newest-control-plane

Kubernetes SidecarContainers feature is merged
The KEP (Kubernetes Enhancement Proposal) is linked to in the PR [1]. From the summary:
> Sidecar containers are a new type of containers that start among the Init containers, run through the lifecycle of the Pod and don’t block pod termination. Kubelet makes a best effort to keep them alive and running while other containers are running.

What's there in K8s 1.27
This is where the new feature of mutable scheduling directives for jobs comes into play. This feature enables the updating of a job's scheduling directives before it begins. Essentially, it allows custom queue controllers to influence pod placement without needing to directly handle the assignment of pods to nodes themselves. To learn more about this check out the Kubernetes Enhancement Proposal 2926.

Dependencies between Services
What your asking is a (vanilla) Kubernetes non-goal, others have mentioned fluxcd and other add ons that provide primitives for dependency aware deployments. The problem space is so large, that it's unreasonable to to address these concerns in Kubernetes itself, instead, make it extensible... Look at this KEP for example: https://github.com/kubernetes/enhancements/issues/753 Sidecar containers have existed, and been named as such since WAY before that KEP's inception, defining what these things should and shouldn't do is largely arbitrary. Aka: your use-case is niche, if you don't like the behavior, use flux or argo, or write something yourself.
- When you learn the Sidecar Container KEP got dropped from the Kubernets release. Again.

Kubernetes 1.27 will be out next week! - Learn what's new and what's deprecated - Group volume snapshots - Pod resource updates - kubectl subcommands … And more!
If further interested, I may recommend checking out the KEP. I love how they document the decision making, and all these edge cases :).
