MinIO App


Minio is a high performance S3 compatible Object Storage.

Admin credentials

To change admin credentials, use the File manager to edit the variables MINIO_ROOT_USER and MINIO_ROOT_PASSWORD in /app/data/ .

export MINIO_ROOT_USER=superadmin
export MINIO_ROOT_PASSWORD='Secr$et#pass'

Be sure to restart the app after making changes.

Default SSO Policy

By default, Cloudron users have readwrite access policy. To change it:

export MINIO_IDENTITY_OPENID_ROLE_POLICY="new-policy-name"

Be sure to restart the app and re-login for changes to take effect.


MinIO uses two domains:

  • Console domain - this domain is for accessing the MinIO console.

  • API Domain - this endpoint responds to S3 API requests. This is the domain that you need to put into various configs and tools like s3cmd. Only the domain name is needed, no port should be added.

In the screenshot below, you would use as the console domain. You can login and view your files. The is the API domain which responds to API requests.

Cloudron Backup

Cloudron supports backing up to minio. Backing up a Cloudron to a minio installed in another Cloudron will work fine. However, backing up a Cloudron to a minio installed in the very same Cloudron is not supported.

Custom configuration

Custom config variables can be exported in /app/data/ This file is sourced automatically on startup.

Access keys

Access Key and Secret Key can be created in two ways in the Identity section.

  • Create a user - The access key is the username and the corresponding secret key is the password.
  • Create a service account - These are accounts with policies but cannot login to the MinIO dashboard.


MinIO supports multiple long term users in addition to default user created during server startup. New users have to added using the CLI tool. You can read the full docs here.
