For downloading data from minio to your container to populate your PV

Parameters are read from the following environment variables

• MINIO_URL = address and port for the minio server. Does not need scheme.
• ACCESSKEY = Minio access key
• SECRETKEY = Minio secret key
• SRC = Source of the files you wish to copy to your container.
  Takes form of bucketname/path/file or bucketname/path for all contents in a folder
• DEST = Path to where you wish data to inside your container

Special note for the DEST paramert. If you are downloading all files from a dir, don't include that dir name in your DEST Value. For example. If you were downloading all the contents from users/roles do not make your destination /data/users/roles. Do make it /data/users. The roles directory will be created as part of the download.

Because the access key and secret key should not sit in plane text in a git repo or ConfigMap. These credential will be stored in Kubernetes as a Secret

Kubectl create secret generic minio-creds --from-literal=accesskey=youraccesskeyhere --from-literal=secretkey=yoursecretkeyhere 

Include this in your current deployment. Modify the env values to match your environment.
The name of the container can be changed to whatever you wish

 initContainers:
  - name: data-loader 
    image: jpweber/minio-init-dl
    env:
    - name: MINIO_URL
      value: "minio.k8sdev.example.com"
    - name: ACCESSKEY
      valueFrom:
        secretKeyRef:
          name: minio-creds
          key: accesskey
    - name: SECRETKEY
      valueFrom:
        secretKeyRef:
          name: minio-creds
          key: secretkey
    - name: SRC
      value: "training-data/foo/"
    - name: DEST
      value: "/data"
    volumeMounts:
    - mountPath: /data
      name: db-storage

Assumes you already have a mount named db-storage in your main container.

Set your variables like the example below

export MINIO_URL="192.168.2.66:9000"
export SRC="vectorizer/roles"
export ACCESSKEY="LEB3JJ3OCBN4HTDIS5IZ"
export SECRETKEY="xs3fx83cMkV7Oh+6jlGGTt9kTmT5D6yoQLm9+L5X"
export DEST="/tmp/minio-tests/examples"

Then you can run the binary with out any extra parameters

docker run -ti -v /tmp:/tmp \
-e MINIO_URL="192.168.2.66:9000" \
-e ACCESSKEY="LEB3JJ3OCBN4HTDIS5IZ" \
-e SECRETKEY="xs3fx83cMkV7Oh+6jlGGTt9kTmT5D6yoQLm9+L5X" \
-e SRC="vectorizer/roles" \
-e DEST="/tmp/minio-tests/examples/" \
