During the agile design and architecture process of your new (web) service, two key questions will often be:
Generate a certificate-key pair. MinIO secret. Generate a set of random 20 & 64 character alpha-numeric keys for MinIO. To let GitLab have access to incoming. About Django Secret Key Generator. The Django Secret Key Generator is used to generate a new SECRETKEY that you can put in your settings.py module. To show this, I created a Docker-Compose file under data/ that will create a four node cluster of minio. The Access- and Sec-Key is set to minio/minio123. The Access- and Sec-Key is set to minio. Docker network create -driver overlay ntwminio Deploying 4 instances (Minio Erasure Code) Run this the leader node: Create your own MINIOACCESSKEY and MINIOSECRETKEY values! Ensure access key = 5 to 20 characters; Ensure secret key = 8 to 40 characters.
- How are we going to deal with object storage?
MinIO Custom Access and Secret Keys using Docker secrets. To override MinIO's auto-generated keys, you may pass secret and access keys explicitly by creating access and secret keys as Docker secrets. MinIO server also allows regular strings as access and secret keys.
- Is there a better way than getting locked into Amazon S3 etc.?
Yes, and yes! Hello cloud-native world, meet Minio, your private, on-your-own-terms object storage solution, on any public cloud or server.
This blog post will guide you on how to run your cloud object storage on any server with Minio and Cloud 66 backed by Kubernetes.
What is Object storage?
Object storage, also known as object-based storage, is a computer data storage architecture that manages data as objects, as opposed to other storage architectures like file systems, which manage data as a file hierarchy, and block storage, which manages data as blocks within sectors and tracks.
Each object typically includes the data itself, a variable amount of metadata, and a globally unique identifier.
What is Minio?
Minio is an object storage server, compatible with the Amazon S3 cloud storage service. It is best suited for storing unstructured data such as photos, videos, log files, backups, and container/VM images. Object size can range from a few KBs to a maximum of 5TB.
Minio is like owning your own S3 Cloud on your premises, under your data privacy laws, and on your own terms—and it's very easy to setup with Cloud 66 on any public cloud or your own servers!
Run Minio locally for testing
Before running Minio in production, let's give it a test spin on your local box.
Just install docker and docker-compose (instructions here) and use the following docker-compose.yml.
Run docker-compose up and hit the end-point http://localhost:9000, then use the MINIO_ACCESS_KEY and MINIO_SECRET_KEY credentials to login.
BAM! You have your own S3-like object storage!
How to use it
Minio is compatible with all S3 commands—if your service can talk to S3 you can talk to Minio! No code changes.
Let's use an S3 command line tool called s3cmd as an example. You can find all the details here.
To play around with your local instalment, edit the following fields in your s3cmd configuration file ~/.s3cfg
Create a bucket in your brand new object storage:
s3cmd mb s3://hello-world-bucket
Add some files to your new bucket:
s3cmd put FILE [FILE..] s3://hello-world-bucket
List the contents of your bucket:
s3cmd ls s3://hello-world-bucket
Or use the UI to manage your buckets and files.
Run in production
It's time to run production on any cloud provider or on your own server.
We are going to deploy Minio on our Cloud 66 for Containers offering—a complete solution for building, running, and maintaining containerized apps in production. This will allow you to run a multi-tenant setup on your own server(s).
Sign-up to Cloud 66, of course ;-)
- Create a new Project and use the following
service.yml
A service.yml is a Cloud 66 service definition file that tells you which services we want to run on your infrastructure. (For more about service.yml, check our documentation.)
Given the ephemeral nature of containers, it’s important to consider storage solutions to avoid data loss. That's the reason you find the volume statement in service.yml
Choose to deploy in a production environment
Choose which provider you want to deploy (make sure you entered your provider credentials) or bring your own server using our registered server feature.
Hit deploy! and wait until we're done with all the heavy lifting. After a couple of minutes, you will have deployed your own object storage, backed by Kubernetes!
Yes! Kubernetes in Space.
Securing Minio with SSL
Of course, this instalment is not secure because we are using HTTP and not HTTPS. Cloud 66 support Let's Encrypt (FREE!) SSL, or you can bring your own SSL.
Again, we take care of all the heavy lifting and when the SSL certificate is created and installed, you have your Minio running with SSL!
Look! Green lock! ;-)
Test drive production
To start using your production Minio service. Edit the following fields in your s3cmd configuration file ~/.s3cfg
Check if you can create a bucket in your brand new object storage:
s3cmd mb s3://hello-world-bucket
BAM! Object storage at your service.
Summary
Deploying your own S3-compatible object storage is as simple as buying a pair of shoes. It's fun running Minio on any server! Give us a spin a let us know what you think of our services.
Start using the space!
MinIO is an object storage server, compatible with Amazon S3 cloud storage service, mainly used for storing unstructured data (such as photos, videos, log files, etc.)
Generating a new private key android. Generate a new secret key. To generate the key, follow the same process as the one for generating a new private key. You use the Security library in each case. Import encrypted keys more securely. Android 9 (API level 28) and higher allow you to import encrypted keys securely into the Keystore using an ASN.1‑encoded key format.

The above command sets the MinIO Server access key and secret key to minio-access-key and minio-secret-key, respectively.
Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
Tip: You can use the default values.yaml
Configuration and installation details
It is strongly recommended to use immutable tags in a production environment. This ensures your deployment does not change automatically if the same tag is updated with a different image.
Bitnami will release a new chart updating its containers if a new version of the main container, significant changes, or critical vulnerabilities exist.

Production configuration
This chart includes a values-production.yaml file where you can find some parameters oriented to production configuration in comparison to the regular values.yaml. You can use this file instead of the default one.
- MinIO server mode:
- Disable MinIO Web UI:
- Annotations to be added to pods:
- Pod resources:
- Enable NetworkPolicy:
- Don't require client label for connections:
- Change Prometheus authentication:
Distributed mode
You can start the MinIO chart in distributed mode with the following parameter: mode=distributed
This chart sets Minio server in distributed mode with 4 nodes by default. You can change the number of nodes setting the statefulset.replicaCount parameter, for example to statefulset.replicaCount=8
Minio Generate Random Access Key Generator
Note: that the number of replicas must even, greater than 4 and lower than 32
Prometheus exporter
MinIO exports Prometheus metrics at /minio/prometheus/metrics. To allow Prometheus collecting your MinIO metrics, modify the values.yaml adding the corresponding annotations:
Find more information about MinIO metrics at https://docs.min.io/docs/how-to-monitor-minio-using-prometheus.html
Persistence
The Bitnami MinIO image stores data at the /data path of the container.
The chart mounts a Persistent Volume at this location. The volume is created using dynamic volume provisioning.
Adjust permissions of persistent volume mountpoint
As the image run as non-root by default, it is necessary to adjust the ownership of the persistent volume so that the container can write data into it.
Minio Generate Random Access Key Generator
By default, the chart is configured to use Kubernetes Security Context to automatically change the ownership of the volume. However, this feature does not work in all Kubernetes distributions.As an alternative, this chart supports using an initContainer to change the ownership of the volume before mounting it in the final destination.
Random Access File
You can enable this initContainer by setting volumePermissions.enabled to true.
