Addresses #1273 # Summary This pass does three things: 1. Updates all tutorials related to Operator/Tenant deployment for Kustomize and Helm 2. Removes references to Operator Console + updates to reference Kustomize/Helm wherever possible 3. Slightly tidies up old or dangling references This pass does not do these things: - Link out heavily to Kubernetes docs (for later) - Clean up organization (singleplat build handles this) - Addresses OpenShift, Rancher, etc. --------- Co-authored-by: Andrea Longo <feorlen@users.noreply.github.com> Co-authored-by: Allan Roger Reid <allanrogerreid@gmail.com> Co-authored-by: Daryl White <53910321+djwfyi@users.noreply.github.com>

Overview
|
|
--------
|
|
|
|
Helm is a tool for automating the deployment of applications to Kubernetes clusters.
|
|
A `Helm chart <https://helm.sh/docs/topics/charts/>`__ is a set of YAML files, templates, and other files that define the deployment details.
|
|
The following procedure uses a Helm Chart to install the :ref:`MinIO Kubernetes Operator <minio-operator-installation>` to a Kubernetes cluster.
|
|
|
|
Prerequisites
|
|
-------------
|
|
|
|
See the :ref:`Operator Prerequisites <minio-operator-prerequisites>` for a baseline of requirements.
|
|
Helm installations have the following additional requirements:
|
|
|
|
* `Helm <https://helm.sh/docs/intro/install/>`__ (Use the Version appropriate for your Kubernetes API version)
|
|
* `yq <https://github.com/mikefarah/yq/#install>`__
|
|
|
|
For more about Operator installation requirements, including supported Kubernetes versions and TLS certificates, see the :ref:`Operator deployment prerequisites <minio-operator-prerequisites>`.
|
|
|
|
This procedure assumes familiarity with the referenced Kubernetes concepts and utilities.
|
|
While this documentation may provide guidance for configuring or deploying Kubernetes-related resources on a best-effort basis, it is not a replacement for the official :kube-docs:`Kubernetes Documentation <>`.
|
|
|
|
.. _minio-k8s-deploy-operator-helm-repo:
|
|
|
|
Install the MinIO Operator using Helm Charts
|
|
--------------------------------------------
|
|
|
|
The following procedure installs the Operator using the MinIO Operator Chart Repository.
|
|
This method supports a simplified installation path compared to the :ref:`local chart installation <minio-k8s-deploy-operator-helm-local>`.
|
|
You can modify the Operator deployment after installation.
|
|
|
|
.. important::
|
|
|
|
If you use Helm charts to install the Operator, you must use Helm to manage that installation.
|
|
Do not use ``kubectl krew``, Kustomize, or similar methods to update or manage the MinIO Operator installation.
|
|
|
|
#. Add the MinIO Operator Repo to Helm
|
|
|
|
MinIO maintains a Helm-compatible repository at https://operator.min.io.
|
|
Add this repository to Helm:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
helm repo add minio-operator https://operator.min.io
|
|
|
|
You can validate the repo contents using ``helm search``:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
helm search repo minio-operator
|
|
|
|
The response should resemble the following:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
NAME CHART VERSION APP VERSION DESCRIPTION
|
|
minio-operator/minio-operator 4.3.7 v4.3.7 A Helm chart for MinIO Operator
|
|
minio-operator/operator 6.0.1 v6.0.1 A Helm chart for MinIO Operator
|
|
minio-operator/tenant 6.0.1 v6.0.1 A Helm chart for MinIO Operator
|
|
|
|
The ``minio-operator/minio-operator`` is a legacy chart and should **not** be installed under normal circumstances.
|
|
|
|
#. Install the Operator
|
|
|
|
Run the ``helm install`` command to install the Operator.
|
|
The following command specifies and creates a dedicated namespace ``minio-operator`` for installation.
|
|
MinIO strongly recommends using a dedicated namespace for the Operator.
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
helm install \
|
|
--namespace minio-operator \
|
|
--create-namespace \
|
|
operator minio-operator/operator
|
|
|
|
#. Verify the Operator installation
|
|
|
|
Check the contents of the specified namespace (``minio-operator``) to ensure all pods and services have started successfully.
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
kubectl get all -n minio-operator
|
|
|
|
The response should resemble the following:
|
|
|
|
.. code-block:: shell
|
|
|
|
NAME READY STATUS RESTARTS AGE
|
|
pod/minio-operator-699f797b8b-th5bk 1/1 Running 0 25h
|
|

|
|
|
|

|
|
service/operator ClusterIP 10.43.44.204 <none> 4221/TCP 25h
|
|

|
|
|
|

|
|

|
|
|
|
NAME DESIRED CURRENT READY AGE
|
|
replicaset.apps/minio-operator-79f7bfc48 2 2 2 123m
|
|
|
|
You can now :ref:`deploy a tenant using Helm Charts <deploy-tenant-helm>`.
|
|
|
|
.. _minio-k8s-deploy-operator-helm-local:
|
|
|
|
Install the MinIO Operator using Local Helm Charts
|
|
--------------------------------------------------
|
|
|
|
The following procedure installs the Operator using a local copy of the Helm Charts.
|
|
This method may support easier pre-configuration of the Operator compared to the :ref:`repo-based installation <minio-k8s-deploy-operator-helm-repo>`
|
|
|
|
#. Download the Helm charts
|
|
|
|
On your local host, download the Operator Helm charts to a convenient directory:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
:substitutions:
|
|
|
|
curl -O https://raw.githubusercontent.com/minio/operator/master/helm-releases/operator-|operator-version-stable|.tgz
|
|
|
|
|
|
#. (Optional) Modify the ``values.yaml``
|
|
|
|
The chart contains a ``values.yaml`` file you can customize to suit your needs.
|
|
For details on the options available in the MinIO Operator ``values.yaml``, see :ref:`minio-operator-chart-values`.
|
|
|
|
For example, you can change the number of replicas for ``operators.replicaCount`` to increase or decrease pod availability in the deployment.
|
|
See :ref:`minio-operator-chart-values` for more complete documentation on the Operator Helm Chart and Values.
|
|
|
|
For more about customizations, see `Helm Charts <https://helm.sh/docs/topics/charts/>`__.
|
|
|
|
#. Install the Helm Chart
|
|
|
|
Use the ``helm install`` command to install the chart.
|
|
The following command assumes the Operator chart is saved to ``./operator`` relative to the working directory.
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
helm install \
|
|
--namespace minio-operator \
|
|
--create-namespace \
|
|
minio-operator ./operator
|
|
|
|
#. To verify the installation, run the following command:
|
|
|
|
.. code-block:: shell
|
|
:class: copyable
|
|
|
|
kubectl get all --namespace minio-operator
|
|
|
|
If you initialized the Operator with a custom namespace, replace
|
|
``minio-operator`` with that namespace.
|
|
|
|
The output resembles the following:
|
|
|
|
.. code-block:: shell
|
|
|
|
NAME READY STATUS RESTARTS AGE
|
|
pod/minio-operator-7976b4df5b-rsskl 1/1 Running 0 81m
|
|
pod/minio-operator-7976b4df5b-x622g 1/1 Running 0 81m
|
|
|
|
NAME TYPE CLUSTER-IP EXTERNAL-IP PORT(S) AGE
|
|
service/operator ClusterIP 10.110.113.146 <none> 4222/TCP,4233/TCP 81m
|
|
|
|
NAME READY UP-TO-DATE AVAILABLE AGE
|
|
deployment.apps/minio-operator 2/2 2 2 81m
|
|
|
|
NAME DESIRED CURRENT READY AGE
|
|
replicaset.apps/minio-operator-7976b4df5b 1 1 1 81m
|
|
|
|
You can now :ref:`deploy a tenant using Helm Charts <deploy-tenant-helm>`.
