You can use Tanka and jsonnet-bundler to generate Kubernetes YAML manifests from the jsonnet files.

1. Install tanka and jb:

   Follow the steps at https://tanka.dev/install. If you have go installed locally you can also use:

# make sure to be outside of GOPATH or a go.mod project
go install github.com/grafana/tanka/cmd/tk@latest
go install github.com/jsonnet-bundler/jsonnet-bundler/cmd/jb@latest

2. Set up a Jsonnet project, based on the example that follows:

• Initialize Tanka
• Install Grafana Tempo and Kubernetes Jsonnet libraries
• Set up an environment

#!/usr/bin/env bash
# SPDX-License-Identifier: AGPL-3.0-only

set -e

# Initialise the Tanka.
mkdir jsonnet-example && cd jsonnet-example
tk init --k8s=1.26

# Install Tempo jsonnet.
jb install github.com/grafana/tempo/operations/jsonnet/microservices@main
jb install github.com/grafana/jsonnet-libs/memcached

# Use the provided example. In tempo repository in operations/jsonnet-compiled
cp operations/jsonnet-compliled/util/example/main.jsonnet environments/default/main.jsonnet

# Generate the YAML manifests.
export PAGER=cat
tk show environments/default

3. Generate the Kubernetes YAML manifests and store them in the ./manifests directory:

   # Generate the YAML manifests:
   export PAGER=cat
   tk show environments/default
   tk export manifests environments/default

4. Configure the environment specification file at environments/default/spec.json.

To learn about how to use Tanka and to configure the spec.json file, see Using Jsonnet: Creating a new project.

5. Deploy the manifests to a Kubernetes cluster, in one of two ways:

   • Use the tk apply command.

   Tanka supports commands to show the diff and apply changes to a Kubernetes cluster:

   # Show the difference between your Jsonnet definition and your Kubernetes cluster:
   tk diff environments/default
   
   # Apply changes to your Kubernetes cluster:
   tk apply environments/default

   • Use the kubectl apply command.

   You generated the Kubernetes manifests and stored them in the ./manifests directory in the previous step.

   You can run the following command to directly apply these manifests to your Kubernetes cluster:

   # Review the changes that will apply to your Kubernetes cluster:
   kubectl apply --dry-run=client -k manifests/
   
   # Apply the changes to your Kubernetes cluster:
   kubectl apply -k manifests/
