Console Settings

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

You can establish or modify settings by defining:

an environment variable on the host system prior to starting or restarting the AIStor 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 AIStor uses the environment variable value.

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

Each configuration setting controls fundamental MinIO AIStor behavior and functionality. Test 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 Console UI.

Enable embedded console

Optional

MINIO_BROWSER

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

Specify off to disable the embedded Console UI.

Animation

Optional

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

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

Browser redirect

Optional

MINIO_BROWSER_REDIRECT

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

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

Browser redirect URL

Optional

MINIO_BROWSER_REDIRECT_URL

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

If you want to host the Console UI 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 Console UI. 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 Object Store runs.

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

Session duration

Optional

MINIO_BROWSER_SESSION_DURATION

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

MinIO AIStor supports the following units of time measurement:

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

Defaults to 12h.

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

Log query URL

Optional

MINIO_LOG_QUERY_URL

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

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

Content security policy

Optional

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

MINIO_BROWSER_CONTENT_SECURITY_POLICY

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

browser csp_policy

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

Strict transport security

Optional

Configure Console UI 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.

MINIO_BROWSER_HSTS_SECONDS

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.

export MINIO_BROWSER_HSTS_SECONDS=31536000

browser hsts_seconds

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.

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

MINIO_BROWSER_HSTS_INCLUDE_SUB_DOMAINS

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

export MINIO_BROWSER_HSTS_INCLUDE_SUB_DOMAINS="on"

browser hsts_include_subdomains

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

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

MINIO_BROWSER_HSTS_PRELOAD

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

export MINIO_BROWSER_HSTS_PRELOAD="on"

browser hsts_preload

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

mc admin config set ALIAS 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

mc admin config set ALIAS browser hsts_seconds=31536000

Strict-Transport-Security: max-age=31536000

hsts_include_subdomains

mc admin config set ALIAS browser hsts_seconds=31536000 hsts_include_subdomains=on

Strict-Transport-Security: max-age=31536000; includeSubDomains

hsts_preload

mc admin config set ALIAS browser hsts_seconds=31536000 hsts_include_subdomains=on hsts_preload=on

Strict-Transport-Security: max-age=31536000; includeSubDomains; preload

Referrer policy

Optional

Configure Console UI to generate a Referrer-Policy header in HTTP responses. Defaults to strict-origin-when-cross-origin.

MINIO_BROWSER_REFERRER_POLICY

export MINIO_BROWSER_REFERRER_POLICY="strict-origin-when-cross-origin"

browser referrer_policy

mc admin config set ALIAS browser \
   referrer_policy="strict-origin-when-cross-origin" \
   [ARGUMENT=VALUE ...]

Prometheus settings

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

Prometheus URL

Optional

MINIO_PROMETHEUS_URL

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

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

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

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

Prometheus job ID

Optional

MINIO_PROMETHEUS_JOB_ID

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

MinIO AIStor defaults to minio-job.

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

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

Prometheus auth token

Optional

MINIO_PROMETHEUS_AUTH_TOKEN

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:

eyJhbGciOiJIUzUxMiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJwcm9tZXRoZXVzIiwic3ViIjoibWluaW8iLCJleHAiOjQ4NTAwMzg0MDJ9.GZCKR3d0FH2TCvNHSd39HaVfSuQVVV0s8glICBDmhT51V6CQ_hw8gTYlKHJmcpR8aHkqiJwCqcYJhaMmqwe00XY

If you are using a standalone Console UI process, this variable corresponds with CONSOLE_PROMETHEUS_AUTH_TOKEN.

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