spark-on-k8s-operator
Kubernetes operator for managing the lifecycle of Apache Spark applications on Kubernetes.
Project mention: So many sparks on K8s... Could anyone give me a few explanations please ? | reddit.com/r/apachespark | 2021-10-27Spark-Operator (as I understand, Spark-Operator integrates well with K8s while vanilla Spark integration with K8s seems extremely complex to maintain)

Project mention: How long does it take to learn go and program a K8s operator? | reddit.com/r/kubernetes | 2021-12-24
Believe it or not, you can write a Kubernetes operator using simple shell scripts: https://github.com/flant/shell-operator
-
Scout APM
Less time debugging, more time building. Scout APM allows you to find and fix performance issues with no hassle. Now with error monitoring and external services monitoring, Scout is a developer's best friend when it comes to application development.

$ curl -sL https://github.com/operator-framework/operator-lifecycle-manager/releases/download/v0.18.3/install.sh | bash -s v0.18.3
-
clickhouse-operator
The Altinity Operator for ClickHouse creates, configures and manages ClickHouse clusters running on Kubernetes
Altinity is doing a good job of this with Clickhouse. They offer some decent open source guides for self hosting[0] and offer a hosted option. The hosted option is as self serve as I'd like (you have to get "approved").
-
mysql-operator
Asynchronous MySQL Replication on Kubernetes using Percona Server and Openark's Orchestrator.
+1 for MySQL Operator, however I've never used the "official" one, I deployed several instances with Presslab's https://github.com/bitpoke/mysql-operator I'd say one MySQLCluster for customer (to allow independent version update for the engines).

For multi tenancy you could use this: https://github.com/clastix/capsule

Project mention: K8gb: A cloud native Kubernetes Global Balancer | news.ycombinator.com | 2021-04-27
-

Project mention: One user per pod with Kubernetes or other container orchestration tools | reddit.com/r/kubernetes | 2022-01-20
We have been helping organizations build such multi-instance multi-tenant cloud-native applications. We start with an application Helm chart and create separate release of it per customer/user of that organization. We have an open source Kubernetes Operator that aids in this: https://github.com/cloud-ark/kubeplus
-
metering-operator
The Metering Operator is responsible for collecting metrics and other information about what's happening in a Kubernetes cluster, and providing a way to create reports on the collected data.
Metering Operator. But looks like it's not under active development.
-
Percona has a good option for that.

# cert-manager kubectl apply -f https://github.com/jetstack/cert-manager/releases/latest/download/cert-manager.yaml # open telemetry operator kubectl apply -f https://github.com/open-telemetry/opentelemetry-operator/releases/latest/download/opentelemetry-operator.yaml
-
The deploy folder is in the releases. So if you're installing 0.0.5, you'd go to https://github.com/argoproj-labs/argocd-operator/tree/v0.0.15/deploy
-
operator
Kubernetes operator to manage installation, updation and uninstallation of tektoncd projects (pipeline, …) (by tektoncd)
Now, for the actual deployment of Tekton Pipeline and Triggers - I mentioned an installation via Tekton Operator which might seem like the fastest and the best way to get up and running with everything preconfigured, the operator however (at the time of writing) lacks any actual documentation, so you would need to dig around quite a lot to find any explanation as to how things work, which wouldn't be that big of an problem for me personally. The real problem here though, is that the Operator in OperatorHub isn't up to date and I couldn't find current build/image which renders it more or less useless. I'm sure this will change at some point when Tekton Operator is a little more mature (so keep an eye on it's repository), but until then, other installation options should be used.

Project mention: Kubernetes CronJobs not firing at scheduled times... Help? | reddit.com/r/kubernetes | 2021-02-04
If you are unable to change your nodes timezone you can take a look at CronJobber
-
Project mention: Struggling to understand how Google Groups for RBAC is scalable | reddit.com/r/kubernetes | 2021-03-10
Prior to google groups being supported in any manner we made rbacsync that does analogous. It's a custom controller that takes IaC declarations for rolebindings, and maps a given google group name to them on a per namespace or cluster basis. In GKE, this worked with a user's auth token from GCP (claims were in the JWT). Id expect it to work with your OIDC integration as well.

-
Scylla’s Operator 1.2 release was published with helm charts (find it on Github; plus read our blog and the Release Notes). Now 1.3 and 1.4 are in the making. In addition, our Kubernetes deployment can autoscale! An internal demonstration using https://github.com/scylladb/scylla-cluster-autoscaler was presented and you are welcome to play with it.

Project mention: Opensource K8s operator developed in Go to contribute | reddit.com/r/kubernetes | 2021-06-18
-
I use kubernetes with this operator.
-
nifikop
The NiFiKop NiFi Kubernetes operator makes it easy to run Apache NiFi on Kubernetes. Apache NiFI is a free, open-source solution that support powerful and scalable directed graphs of data routing, transformation, and system mediation logic.
I don't have experience of Nifi, but I'd say your best option is either the operator: https://github.com/Orange-OpenSource/nifikop or the helm chart: https://github.com/cetic/helm-nifi

flink-on-k8s-operator
Kubernetes operator for managing the lifecycle of Apache Flink and Beam applications.
Project mention: Kubernetes operator for managing the lifecycle of Apache Flink and Beam applications. | reddit.com/r/kubernetes | 2021-10-13 -
