MinIO Kubernetes Plugin
Overview
Current Stable Version is 5.0.9
This reference documentation reflects 5.0.9 of the
MinIO Kubernetes Operator and kubectl minio plugin.
The kubectl minio plugin brings native support for deploying MinIO tenants to Kubernetes clusters using the kubectl CLI.
Use kubectl minio to deploy a MinIO tenant with little to no interaction with YAML configuration files.
Installing kubectl minio implies installing the
MinIO Kubernetes Operator.
Installation
The MinIO Kubernetes Plugin requires Kubernetes 1.19.0 or later.
The following code downloads the latest stable version 5.0.9 of the MinIO Kubernetes Plugin and installs it to the system $PATH.
This procedure uses the Kubernetes krew plugin manager for installing the MinIO Kubernetes Operator and Plugin.
See the krew installation documentation for specific instructions.
kubectl krew update
kubectl krew install minio
wget https://github.com/minio/operator/releases/download/v5.0.9/kubectl-minio_5.0.9_linux_amd64 -O kubectl-minio
chmod +x kubectl-minio
mv kubectl-minio /usr/local/bin/
You can access the plugin using the kubectl minio command. Run
the following command to verify installation of the plugin:
kubectl minio version
Subcommands
kubectl minio has the following subcommands:
Environment Variables
The MinIO Operator uses the following environment variables during startup to set configuration settings.
Configure these variables in the minio-operator container.
Setting Environment Variables in Kubernetes
To set these environment variables, modify the operator container’s yaml at .spec.env or use the following kubectl command syntax:
kubectl set env -n minio-operator deployment/minio-operator <ENV_VARIABLE>=<value> ... <ENV_VARIABLE2>=<value2>
Replace:
minio-operatorwith the namespace for your Operator, if not using the default value.deployment/minio-operatorwith the deployment for your Operator, if not the default value. (This is not common.)<ENV_VARIABLE>with the environment variable to set or modify.<value>with the value to use for the environment variable.
You can set or modify multiple environment variables by separating each VARIABLE=value pair with a space.
