S3 for MinIO

  3 minute read.

Last Modified 2022-08-05 09:54 EDT

MinIO connections and service is configured using the Services S3 screen.

MinIO deprecated Access key and Secret key. MinIO now utilizes MINIO_ROOT USER and MINIO_ROOT_PASSWORD arguments and their values. For the ROOT_USER value, use a name up to 20 characters. For the ROOT_PASSWORD, use a string of 8 to 40 randomized characters. MinIO recommends using a long password string of unique random characters.

Testing Minio Connections

To test access to the MinIO Browser, select Enable Browser. Open a web browser and type the TrueNAS IP address with the TCP port. Example: https://192.168.0.3:9000. Allow the port specified in Port through the network firewall. This permits bucket creation and file uploads.

MinIO Connection Methods

Different methods are used for connecting to and using MinIO:

Linux or macOS users must have the s3cmd service installed before beginning this setup. On Windows, users can also refer to S3Express for a similar command line experience.

The s3cmd --configure command is available for Ubuntu or other Linux distributions. Using this command you can configure important settings step by step.

Enter the specified access key and the secret key. Under the S3 Endpoint, enter the TrueNAS IP address followed by TCP port, and reply N to the DNS-style bucket+hostname.

Save the file. On Linux, the default is in the home directory ~/.s3cfg.

If the connection has any issues, open .s3cfg again to troubleshoot. In Ubuntu, use command nano .s3cfg or vi .s3cfg or gedit .s3cfg depending on the preferred text editor. For other operating systems, .s3cfg file location and editing tools may vary.

Scroll down to the host_bucket area. Make sure the %(bucket)s. portion is removed. The IP address should point to the IP_address:TCP_port for the system.

Correct Example

host_base = `192.168.123.207:9000`
host_bucket = `192.168.123.207:9000`

Incorrect Example

host_base = `192.168.123.207`
host_bucket = `%(bucket)s.192.168.123.207`

Poll the buckets using command s3cmd ls to see the buckets created with the MinIO Browser.

For more information on using MinIO with command s3cmd, see https://docs.minio.io/docs/s3cmd-with-minio.html and https://s3tools.org/s3cmd.

On Windows PCs, the S3 Browser is another convenient way to connect to the MinIO S3 on a TrueNAS system.

To set it up, first install the S3 Browser.

After installation completes, add a new account.

AmazonS3NewAccount

In the S3 Browser settings, select S3 Compatible Storage as the Account Type. Enter the MinIO access point. Example: (TrueNAS_IP_address:9000 or other port). Select the SSL settings appropriate for the particular setup. The default assumes SSL in S3 Browser, but for a LAN attached session, this may or may not already be set.

AmazonS3EditAccount

It is possible to access, create new buckets, or upload files to created buckets.
