Gimlet Stack Intro Gimlet specific content

You can bootstrap curated Kubernetes stacks with Gimlet Stack.

  • You can install logging aggregators, metric collectors, ingress controllers, and more on your cluster with a few commands and without much knowledge of Helm charts and their configuration options

  • The components are delivered through a plain git repository with self-contained gitops automation

  • You will regularly get upgrades for the installed components from the stack curators


Gimlet Stack is a command line tool that you can use to configure curated stacks for Kubernetes clusters.

Stack makers (or curators) maintain the stacks and end-users benefit from the curator's hard-earned best practices as they deploy the curated stacks on their clusters.

A stack instance - with its complete configuration - is stored in a git repository and delivered onto a kubernetes cluster via gitops automation. Gimlet Stack uses Flux V2 as the gitops controller to sync git changes to the cluster.

End-user workflow

  • end-users create a stack.yaml file with the full configuration of their stack: enabling required components and configuring them through a series of options
    • end-users can create the stack.yaml manually
    • or through the stack configure CLI command which opens a browser based UI from the terminal
  • users store the stack.yaml on git
  • users generate HelmRelease resources and other Kubernetes manifests from the components defined in the stack.yaml with the stack generate CLI command
  • users store the generated files in the same git repository as the stack.yaml file
  • users push changes to git, and the bootstrapped gitops loop syncs it to the cluster.
  • users can bootstrap the gitops loop with the stack bootstrap CLI command


Stacks are a set of Helm charts and Kubernetes manifests that are configured to work together seamlessly.

  • stacks use the well-known community Helm charts
  • stacks expose only a subset of helm chart values to users to limit the decision space
  • stacks make it possible to use all chart values if people want the full chart feature set / optionality
  • stacks create new chart values that group together multiple flags, and abstract them at a higher level. Eg.: stickySessions, realIP, HA
  • stacks don't change the community charts, as upstreaming opinions will be a blocker every time. Instead, stacks wrap/compose the community charts
  • stacks are able to deliver raw yamls to the gitops repo, configmaps, etc
