MinIO is high-performance object storage that is API compatible to Amazons Simple Storage Service (S3), but is open source and written in Go. It can be used as a building block for applications involving file storage and file transmission and while its native to the cloud, it turns out one can also use it on gokrazy. :)

Since MinIO is a storage solution, you need to enable permanent storage on your gokrazy installation by running the mkfs command that gokr-packer prints. For more details, see Quickstart.

This article also assumes that you have an instance directory (with a go.mod) set up.

You can find a detailed description on how to set the flags and environment vars in the article per-package configuration.





A few things can be noted here:

  • There are nice practical examples on the different options once you execute minio server --help if you have it installed locally or in the official MinIO docs

  • The ports for the storage server and console do not have to be explicitly set, but for me the default port collided with another service (Port 9000). If no port is set the console just chooses an arbitrary free one.

  • For some reason the HOME variable has to be set to the storage folder. See Issue #12641 on why that is the case. As default gokrazy sets HOME to HOME=/perm/<cmd>, so if you want to change your storage location to something different modify the env.txt accordingly.

In your gokr-packer invocation (see Quickstart if you don’t have one yet), include the MinIO package:

gokr-packer \
  -update=yes \ \ \ \

If you have the mc command installed you can check out whether your installation of MinIO really works:

$ mc alias set gokrazy http://gokrazy:3001 minio miniostorage
Added `gokrazy` successfully.
$ mc ls gokrazy
$ mc mb gokrazy/testbucket
Bucket created successfully `gokrazy/testbucket`.
$ mc ls gokrazy
[2021-09-15 16:40:16 CEST]     0B testbucket/

Also check out the output in the logs on the gokrazy webinterface and login into the MinIO management console (http://gokrazy:3002 in this guide) to create service accounts view logs, bucket contents and more.
