Documentation Grafana Mimir Operator and user guide Deploy on Kubernetes Deploying with Jsonnet and Tanka Deploying with Jsonnet

Deploying Grafana Mimir with Jsonnet and Tanka

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:

   console Copy

   # 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 Mimir and Kubernetes Jsonnet libraries
   • Set up an environment
   sh Copy

   #!/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=1.21
   
   # Install Mimir jsonnet.
   jb install github.com/grafana/mimir/operations/mimir@main
   
   # Use the provided example.
   cp vendor/mimir/mimir-manifests.jsonnet.example 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:

   sh Copy

   # 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:

     sh Copy

     # 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:

     sh Copy

     # 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/

   Note: The generated Kubernetes manifests create resources in the default namespace. To use a different namespace, change the namespace configuration option in the environments/default/main.jsonnet file, and re-generate the Kubernetes manifests.
