• InfluxDB

• terraform

  1 1 7.6 HCL

  Discontinued Terraform (by tyzbit)

NewRelic for logging, monitoring, alerting. For my moderately utilized 6-node cluster, it's about $60/mo. I use Terraform to define all of my alerts and even some dashboards.

• nfs-subdir-external-provisioner

  48 2,364 4.2 Shell

  Dynamic sub-dir volume provisioner on a remote NFS server.

  

Honorable Mentions: - NFS subdir external provisioner - Point it at an NFS server and it automatically creates a folder for each PersistentVolume you create with the StorageClass. - nginx-ingress controller, like someone else mentioned.

• longhorn

  77 5,568 9.4 Shell

  Cloud-Native distributed storage built on and for Kubernetes

  

Longhorn for Kubernetes storage. It lets me automatically provision PersistentVolumes and snapshot/back them up to S3. I've read that other things such as Ceph and Rook are more stable and I've definitely been bit by some non-critical bugs, but the project is very active and bugs are squashed quickly (though they don't release very frequently). This is the gem I can't live without, being able to snapshot, backup and restore things like my Plex volume has saved me at least a dozen times already.

• flux2

  83 5,927 9.2 Go

  Open and extensible continuous delivery solution for Kubernetes. Powered by GitOps Toolkit.

  

Flux for GitOps, it's the only way I install Helm charts anymore. I recently rebuilt my k8s cluster and I went from 0 masters 0 workers to a full cluster with 90% of my apps good to go within an hour.

• Duplicacy

  136 4,998 5.6 Go

  A new generation cloud backup tool

Duplicacy for offsite backup. You have to pay yearly for a license, the first year is $20 while subsequent years are $5. I tried a good amount of enthusiast-grade backup solutions and this one was worth paying for, the rest did not have my confidence.

• WorkOS

  The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  

• cert-manager

  101 11,429 9.6 Go

  Automatically provision and manage TLS certificates in Kubernetes

  

cert-manager for easy SSL certificates.
