Top 23 Go Operator Projects
-
operator-sdk
SDK for building Kubernetes applications. Provides high level APIs, useful abstractions, and project scaffolding.
Maybe that's the point. I am thinking of people who might (mistakenly) assume that they need to maintain multiple Go version on their machines because the project's readme "requires" a particular version. (Example: operator-sdk says "releases are compiled with Go 1.16". Looking deeper into the project, I see the Go version hard-coded into GitHub Action configs, but I see no explanation why the code cannot be compiled with Go 1.17.x instead.)

Project mention: help tips scripting pods creation for k8s cluster testing | reddit.com/r/kubernetes | 2021-11-04
So i came across this recently, haven't used it myself but it seems to fit your requirements: https://github.com/chaos-mesh/chaos-mesh
-
Scout APM
Scout APM: A developer's best friend. Try free for 14-days. Scout APM uses tracing logic that ties bottlenecks to source code so you know the exact line of code causing performance issues and can get back to building a great product faster.

Project mention: PostgreSQL on Cloud SQL or GKE a Kubernetes Node? | reddit.com/r/googlecloud | 2021-11-26
Here are a couple kubernetes operators for Postgres: zaland /postgres-operator, CrunchyData/postgres-operator.

postgres-operator
Production PostgreSQL for Kubernetes, from high availability Postgres clusters to full-scale database-as-a-service. (by CrunchyData)

-
bank-vaults
A Vault swiss-army knife: a K8s operator, Go client with automatic token renewal, automatic configuration, multiple unseal options and more. A CLI tool to init, unseal and configure Vault (auth methods, secret engines). Direct secret injection into Pods.
-
Project mention: GitHub Actions: Ephemeral self-hosted runners and new webhooks for auto-scaling | news.ycombinator.com | 2021-09-20
It's not official, but there are K8s / github actions runner deployments: https://github.com/actions-runner-controller/actions-runner-...
I've been playing about with this and it seems to work quite well. Startup latency is quite high, and it's one pod-per-job (I think), but seems pretty flexible.

Project mention: Event exporter, observability something alternative for opsgenie stack | reddit.com/r/devops | 2021-11-17
Here's another exporter. https://github.com/heptiolabs/eventrouter
-
camel-k
Apache Camel K is a lightweight integration platform, born on Kubernetes, with serverless superpowers
Project mention: Project includes a dependancy that has a license that forbids its use | news.ycombinator.com | 2021-08-22 -
For multi tenancy you could use this: https://github.com/clastix/capsule
-
Project mention: What are the best practice options to use Jenkins for CICD? | reddit.com/r/jenkinsci | 2021-04-07
Possible options considered; Run Jenkins on a master and worker build server on EC2 Run Jenkinsci on Kubernetes with https://github.com/jenkinsci/kubernetes-operator
-
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.
-
Project mention: GitOps using the Terraform Cloud Operator for Kubernetes | reddit.com/r/GitOps | 2021-12-01
Did anyone try https://github.com/hashicorp/terraform-k8s for applying GitOps principles to IaC?
-
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
-
For example, the K8ssandra project uses cass-operator, which defines a Kubernetes custom resource (CRD) called “CassandraDatacenter” to describe the desired state of each top-level failure domain of a Cassandra cluster. This provides a level of abstraction higher than dealing with Stateful Sets or individual pods.
-
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: Secrets... can I get it from aws secret manager? | reddit.com/r/kubernetes | 2021-04-23
I’ve used this in the past, and it’s reliable.
-
etcd-cloud-operator
Deploying and managing production-grade etcd clusters on cloud providers: failure recovery, disaster recovery, backups and resizing.
That's a thing this does! https://github.com/Quentin-M/etcd-cloud-operator
-
Project mention: KubeSphere 3.2.0 GA: Bringing AI-oriented GPU Scheduling and Flexible Gateways to Kubernetes Management | dev.to | 2021-11-17
KubeSphere stays committed to open source with a vibrant ecosystem, which boasts a variety of lightweight, efficient toolkits to make Kubernetes easy. KubeKey, an open source installer, uses Docker as the default container runtime to install Kubernetes efficiently, and now it also supports CRI runtimes like containerd, CRI-O, and iSula after Dockershim deprecation. Other smart tools such as OpenFunction, OpenELB (CNCF Sandbox), Fluent Operator, are all open to everybody and users have access to code and documentation in GitHub repositories.

Project mention: Disaster Recovery Orchestration (or Orchestration in General)? | reddit.com/r/devops | 2021-06-15
At our company, we follow a GitOps everything approach. Not only workload is GitOpsed but also the platform (Kubernetes), monitoring, API Gateway, storage, networking and VMs etc. We developed ORBOS, which is suitable to bring up the Infrastructure and Platform on-prem and in the cloud using GitOps. Disaster recovery becomes easy if a whole systems desired state is declared and each systems state is reproducible on any infrastructure provider. Just right now, I'm writing a blog article outlining it in more detail, advocating to "Treat Clusters as Cattle, Not Pets", stay tuned.
