deploying a minio service to kubernetes

#kubernetes #minio

Here are the basic steps to getting a minio tenant deployed inot kubernetes. There are some pre-requisites tasks to be deployed (and will not be covered in this article) including

Add Helm Respository

Lets start by installing the helm repository

 helm repo add minio-operator https://operator.min.io helm repo update
Enter fullscreen mode Exit fullscreen mode

Create the minio operator

Now lets create the minio operator that we will use later to create the tenant.

Create a file minio-operator.yaml

 console: ingress: enabled: true ingressClassName: "nginx" annotations: cert-manager.io/cluster-issuer: vault-issuer tls: - hosts: - ui-operator-7f000101.nip.io secretName: minio-console-tls host: ui-operator-7f000101.nip.io path: / pathType: Prefix number: 9090
Enter fullscreen mode Exit fullscreen mode

and deploy it using

 helm upgrade --install operator minio-operator/operator --namespace minio-operator --create-namespace -f minio-operator.yaml
Enter fullscreen mode Exit fullscreen mode

Confirm it is running by checking the output of kubectl get pods -n minio-operator which should be similair to

 NAME READY STATUS RESTARTS AGE console-7fcfdb8d98-8kwxd 1/1 Running 0 137m minio-operator-69986bb674-8qdg6 1/1 Running 0 137m minio-operator-69986bb674-pz8rc 1/1 Running 0 137m
Enter fullscreen mode Exit fullscreen mode

we can get the jwt required to access the console by using the following command.

 kubectl get secret/console-sa-secret -n minio-operator -o go-template='{{.data.token | base64decode}}'
Enter fullscreen mode Exit fullscreen mode

Open a web browser to ui-operator-7f000101.nip.io and use the jwt collected before.

Congrats the minio operator has been deployed and lets create a tenant.

Add a tenant

Create a file minio-tenant.yaml

 secrets: name: fido-env-configuration accessKey: admin secretKey: passw0rd tenant: name: fido configuration: name: fido-env-configuration pools: - servers: 1 name: pool size: 200Mi volumesPerServer: 1 ingress: api: enabled: true ingressClassName: "nginx" annotations: cert-manager.io/cluster-issuer: vault-issuer nginx.ingress.kubernetes.io/backend-protocol: "HTTPS" tls: - hosts: - api-fido-7f000101.nip.io secretName: fido-minio-api-tls host: api-fido-7f000101.nip.io path: / pathType: Prefix console: enabled: true ingressClassName: "nginx" annotations: cert-manager.io/cluster-issuer: vault-issuer nginx.ingress.kubernetes.io/backend-protocol: "HTTPS" tls: - hosts: - ui-fido-7f000101.nip.io secretName: fido-minio-console-tls host: ui-fido-7f000101.nip.io path: / pathType: Prefix
Enter fullscreen mode Exit fullscreen mode

and deploy it using

 helm upgrade --install --namespace minio-fido --create-namespace minio-fido minio-operator/tenant -f minio-tenant.yaml
Enter fullscreen mode Exit fullscreen mode

confirm it is running using kubectl get pods -n minio-fido which should be similair to

 NAME READY STATUS RESTARTS AGE fido-pool-0 2/2 Running 0 68m
Enter fullscreen mode Exit fullscreen mode

Open a web browser to ui-fido-7f000101.nip.io and use the credentials admin:password defined in the secret fido-env-configuration.

Congrats the minio tenant has been deployed and so lets configure the mc command.

mc configuration

Download the mc from the instructions here https://min.io/docs/minio/linux/reference/minio-mc.html#install-mc

open a command prompt / terminal and issue the following

 mc alias set fido/ https://api-fido-7f000101.nip.io admin password
Enter fullscreen mode Exit fullscreen mode

create a bucket and copy a test file to it

  1. Create a bucket
 mc mb fido/backups
Enter fullscreen mode Exit fullscreen mode

returns

 Bucket created successfully `fido/backups`.
Enter fullscreen mode Exit fullscreen mode
  1. Copy a file to it
  # linux/mac touch test  # windows powershell echo $null >> filename  mc cp test fido/backups
Enter fullscreen mode Exit fullscreen mode

returns

 0 B / ? [ =]
Enter fullscreen mode Exit fullscreen mode
  1. list contents of the bucket
 mc ls fido/backups
Enter fullscreen mode Exit fullscreen mode

returns

 [2024-04-09 08:07:58 AEST] 0B STANDARD test
Enter fullscreen mode Exit fullscreen mode

When completed check the operator and bucket ui to see similar to
