Date Mon, 16 Jul 2018 14:06:00 GMT

    [ https://issues.apache.org/jira/browse/IGNITE-8994?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16545239#comment-16545239

Ilya Murchenko commented on IGNITE-8994:


Here are steps which I used to deploy Ignite StatefulSet with dedicated volumes for WAL and

##Create Ignite StatefulSet deployment with dedicated volumes for WAL and Data

1. Specify a Volume Type in storage-class-wal-<aws|gke>.yaml and storage-class-persistence-<aws|gke>.yaml
configuration templates.

2. Create a StorageClass for AWS or GKE

$ kubectl create -f storage-class-wal-aws.yaml

$ kubectl create -f storage-class-wal-gke.yaml

3. Create a PersistentVolumeClaim for AWS or GKE

$ kubectl create -f storage-class-persistence-aws.yaml

$ kubectl create -f storage-class-persistence-gke.yaml

4. Deploy Ignite StatefulSet with dedicated volumes for WAL and Data
$ kubectl create -f ignite-statefulset.yaml


Configuration templates (YAML) are attached.

> Provide StatefulSet configuration that shows how to request separate volumes for the
WAL and data/index files. If needed, provide YAML configs for StorageClass and volume claims.
