🏗️ Usage

This library is intended to be used with Tanka to deploy Kubernetes manifests.

First, install the library using the jsonnet-bundler:

jb install https://github.com/chaudum/crate-sonnet@main

To use this library in a Tanka environment import the crate-sonnet/mai.libsonnet like in the following, minimal example that generates manifests for a 3 node cluster with general purpose nodes.

local crate = import 'crate-sonnet/main.libsonnet';

crate {
  _config+:: {
    namespace: 'my-cratedb-namespace',
    cluster: 'my-cratedb-cluster',

    general_purpose_replicas: 3,
    general_purpose_cpu: '1',
    general_purpose_memory: '1024Mi',
    general_purpose_heap: '512m',

    crate+: {
    },
  },
}
