MinIO Operator 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-operator with the namespace for your Operator, if not using the default value.
deployment/minio-operator with the deployment for your Operator, if not the default value. (Most deployments use the default value.)
<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.
