18.2. Setting up S3 Compatible Object Store for Container-Native Storage

Execute the following steps from the /usr/share/heketi/templates/ directory to set up S3 compatible object store for Container-Native Storage:
  1. (Optional): If you want to create a secret for heketi, then execute the following command: 
    # oc create secret generic heketi-${NAMESPACE}-admin-secret
--from-literal=key=${ADMIN_KEY} --type=kubernetes.io/glusterfs
    Copy to Clipboard Toggle word wrap
    For example: 
    # oc create secret generic heketi-storage-project-admin-secret
--from-literal=key=  --type=kubernetes.io/glusterfs
    Copy to Clipboard Toggle word wrap
    1. Execute the following command to label the secret: 
      # oc label --overwrite secret heketi-${NAMESPACE}-admin-secret
glusterfs=s3-heketi-${NAMESPACE}-admin-secret
gluster-s3=heketi-${NAMESPACE}-admin-secret
      Copy to Clipboard Toggle word wrap
      For example: 
      # oc label --overwrite secret heketi-storage-project-admin-secret
glusterfs=s3-heketi-storage-project-admin-secret
gluster-s3=heketi-storage-project-admin-secret
      Copy to Clipboard Toggle word wrap
  2. Create a GlusterFS StorageClass file. Use the HEKETI_URL and NAMESPACE from the current setup and set a STORAGE_CLASS name. 
    # sed  -e 's/${HEKETI_URL}/heketi-storage-project.cloudapps.mystorage.com/g'  -e 's/${STORAGE_CLASS}/gluster-s3-store/g'      -e  's/${NAMESPACE}/storage-project/g'   /usr/share/heketi/templates/gluster-s3-storageclass.yaml | oc create -f -  
storageclass "gluster-s3-store" created
    Copy to Clipboard Toggle word wrap
  3. Create the Persistent Volume Claims using the storage class. 
    # sed -e 's/${VOLUME_CAPACITY}/2Gi/g'  -e  's/${STORAGE_CLASS}/gluster-s3-store/g'  /usr/share/heketi/templates/gluster-s3-pvcs.yaml | oc create -f - 
persistentvolumeclaim "gluster-s3-claim" created
persistentvolumeclaim "gluster-s3-meta-claim" created
    Copy to Clipboard Toggle word wrap
    Use the STORAGE_CLASS created from the previous step. Modify the VOLUME_CAPACITY as per the environment requirements. Wait till the PVC is bound. Verify the same using the following command: 
    # oc get pvc 
NAME                    STATUS    VOLUME                                     CAPACITY   ACCESSMODES   AGE
gluster-s3-claim        Bound     pvc-0b7f75ef-9920-11e7-9309-00151e000016   2Gi        RWX           2m
gluster-s3-meta-claim   Bound     pvc-0b87a698-9920-11e7-9309-00151e000016   1Gi        RWX           2m
    Copy to Clipboard Toggle word wrap
  4. Start the glusters3 object storage service using the template:

    Note

    Set the S3_ACCOUNT name, S3_USER name, and S3_PASSWORD. PVC and META_PVC are obtained from the previous step. 
    # oc new-app  /usr/share/heketi/templates/gluster-s3-template.yaml \
--param=S3_ACCOUNT=testvolume  --param=S3_USER=adminuser \
--param=S3_PASSWORD=itsmine --param=PVC=gluster-s3-claim \
--param=META_PVC=gluster-s3-meta-claim
--> Deploying template "storage-project/gluster-s3" for "/usr/share/heketi/templates/gluster-s3-template.yaml" to project storage-project

     gluster-s3
     ---------
     Gluster s3 service template


     * With parameters:
        * S3 Account Name=testvolume
        * S3 User=adminuser
        * S3 User Password=itsmine
        * Primary GlusterFS-backed PVC=gluster-s3-claim
        * Metadata GlusterFS-backed PVC=gluster-s3-meta-claim

--> Creating resources ...
    service "gluster-s3-service" created
    route "gluster-s3-route" created
    deploymentconfig "gluster-s3-dc" created
--> Success
    Run 'oc status' to view your app.

  5. Execute the following command to verify if the S3 pod is up: 
    # oc get route
NAME              HOST/PORT                                                            PATH      SERVICES           PORT      TERMINATION   WILDCARD
gluster-S3-route   gluster-s3-route-storage-project.cloudapps.mystorage.com ... 1 more             gluster-s3-service   <all>                   None
heketi            heketi-storage-project.cloudapps.mystorage.com ... 1 more                      heketi             <all>
