Silo Console Settings

Changed: RELEASE.2025-05-24T17-08-30Z

The Console now presents only object browser capabilities similar to those available through the mc tool. For administrative interactions, such as user management, use the mc admin command.

Some of the settings on this page may no longer be relevant for newer deployments.

This page covers settings that manage access and behavior for the MinIO Console.

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the MinIO Server. Refer to your operating system’s documentation for how to define an environment variable.
a configuration setting using mc admin config set.

If you define both an environment variable and the similar configuration setting, MinIO uses the environment variable value.

Some settings have only an environment variable or a configuration setting, but not both.

Important

Each configuration setting controls fundamental MinIO behavior and functionality. MinIO strongly recommends testing configuration changes in a lower environment, such as DEV or QA, before applying to production.

Browser Settings

The following settings control behavior for the embedded MinIO Console.

MinIO Console

Optional

Environment Variable

`MINIO_BROWSER`

envvar

Specify off to disable the embedded MinIO Console.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Animation

Optional

Environment Variable

`MINIO_BROWSER_LOGIN_ANIMATION`

envvar

Added: MinIO

Server RELEASE.2023-05-04T21-44-30Z

Specify off to disable the animated login screen for the MinIO Console. Defaults to on.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Browser Redirect

Optional

Environment Variable

`MINIO_BROWSER_REDIRECT`

envvar

Added: MinIO

Server RELEASE.2023-09-16T01-01-47Z

Specify whether requests from a web browser automatically redirect to the Console address. Defaults to true.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Browser Redirect URL

Optional

Environment Variable

`MINIO_BROWSER_REDIRECT_URL`

envvar

Specify the Fully Qualified Domain Name (FQDN) the MinIO Console listens for incoming connections on.

If you want to host the MinIO Console exclusively from a reverse-proxy service, you must specify the hostname managed by that service.

For example, consider a reverse proxy configured to route https://example.net/minio/ to the MinIO Console. You must set this environment variable to match that hostname for the Console to both listen and respond to requests using that hostname.

If you omit this variable, the Console listens and responds to all IP addresses or hostnames associated to the host machine on which the MinIO Server runs.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Session Duration

Optional

Environment Variable

`MINIO_BROWSER_SESSION_DURATION`

envvar

Added: MinIO

Server RELEASE.2023-08-23T10-07-06Z

Specify the duration of a browser session for working with the MinIO Console.

MinIO supports the following units of time measurement:

s - seconds, “60s”
m - minutes, “60m”
h - hours, “24h”
d - days, “7d”

Defaults to 12h.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Log Query URL

Optional

Environment Variable

`MINIO_LOG_QUERY_URL`

envvar

Specify the URL of a PostgreSQL service to which MinIO writes Audit logs. The embedded MinIO Console provides a Log Search tool that allows querying the PostgreSQL service for collected logs.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Content Security Policy

Optional

Configure MinIO Console to generate a Content-Security-Policy header in HTTP responses. Defaults to default-src 'self' 'unsafe-eval' 'unsafe-inline';

Environment Variable

`MINIO_BROWSER_CONTENT_SECURITY_POLICY`

envvar

BASH

export MINIO_BROWSER_CONTENT_SECURITY_POLICY="default-src 'self' 'unsafe-eval' 'unsafe-inline';"

Configuration Setting

`browser csp_policy`

mc-conf

BASH

mc admin config set browser \
   csp_policy="default-src 'self' 'unsafe-eval' 'unsafe-inline';" \
   [ARGUMENT=VALUE ...]

Strict Transport Security

Optional

Configure MinIO console to generate a Strict-Transport-Security header in HTTP responses.

To generate the header, you must set a duration using either MINIO_BROWSER_HSTS_SECONDS or hsts_seconds. Other HSTS settings are optional.

Environment Variables

`MINIO_BROWSER_HSTS_SECONDS`

envvar

The max_age the configured policy remains in effect, in seconds. Defaults to 0, disabled. You must configure a non-zero duration to enable the Strict-Transport-Security header.

BASH

export MINIO_BROWSER_HSTS_SECONDS=31536000

`MINIO_BROWSER_HSTS_INCLUDE_SUB_DOMAINS`

envvar

Set to on to also apply the configured HSTS policy to all MinIO Console subdomains. Defaults to off.

BASH

export MINIO_BROWSER_HSTS_INCLUDE_SUB_DOMAINS="on"

`MINIO_BROWSER_HSTS_PRELOAD`

envvar

Set to on to direct the client browser to add the MinIO Console domain to its HSTS preload list. Defaults to off.

BASH

export MINIO_BROWSER_HSTS_PRELOAD="on"

Configuration Settings

The following configuration settings require a service restart to take effect. To restart the service, use mc admin service restart.

`browser hsts_seconds`

mc-conf

The max_age the configured policy remains in effect, in seconds. Defaults to 0, disabled. You must configure a non-zero duration to enable the Strict-Transport-Security header.

BASH

mc admin config set browser \
   hsts_seconds="31536000" \
   [ARGUMENT=VALUE ...]

`browser hsts_include_subdomains`

mc-conf

Set to on to also apply the configured HSTS policy to all MinIO Console subdomains. Defaults to off.

BASH

mc admin config set browser \
   hsts_include_subdomains="on" \
   hsts_seconds="31536000" \
   [ARGUMENT=VALUE ...]

`browser hsts_preload`

mc-conf

Set to on to direct the client browser to add the MinIO Console domain to its HSTS preload list. Defaults to off.

BASH

mc admin config set browser \
   hsts_preload="on" \
   hsts_seconds="31536000" \
   [ARGUMENT=VALUE ...]

Examples

The following examples show the rendered header for the given configuration settings. The equivalent environment variables generate the same result. All examples use a value of 31536000, which is the number of seconds in a calendar year (365 days).

hsts_seconds

Prometheus Settings

The following settings manage how MinIO interacts with your Prometheus service.

Prometheus URL

Optional

Environment Variable

`MINIO_PROMETHEUS_URL`

envvar

Specify the URL for a Prometheus service configured to scrape MinIO metrics.

The MinIO Console populates the Dashboard with cluster metrics using the minio-job Prometheus scraping job.

If you are using a standalone MinIO Console process, this variable corresponds with CONSOLE_PROMETHEUS_URL.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Prometheus Job ID

Optional

Environment Variable

`MINIO_PROMETHEUS_JOB_ID`

envvar

Specify the custom Prometheus job ID used for scraping MinIO metrics.

MinIO defaults to minio-job.

If you are using a standalone MinIO Console process, this variable corresponds with CONSOLE_PROMETHEUS_JOB_ID.

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.

Prometheus Auth Token

Optional

Environment Variable

`MINIO_PROMETHEUS_AUTH_TOKEN`

envvar

Specify the basic auth token the Console should use to connect to a Prometheus service.

For example, a basic auth token you might use could resemble the following:

TEXT

Configuration Setting

This setting does not have a configuration variable setting. Use the Environment Variable instead.
