| # Deploy DM on Kubernetes | ||
|
|
||
| This document describes how to deploy DM of the new HA architecture with the yamls in this directory. | ||
|
|
||
| ## Deploy dm-master | ||
|
|
||
| {{< copyable "shell-regular" >}} | ||
|
|
||
| ``` shell | ||
| kubectl create -f master/dm-master.yaml -n <namespace> | ||
| ``` | ||
|
|
||
| > **Note: ** | ||
| > | ||
| > - `3` replicas are deployed by default. | ||
| > - `storageClassName` is set to `local-storage` by default. | ||
|
|
||
| ## Deploy dm-worker | ||
|
|
||
| - If you only need to use DM for incremental data migration, no need to create PVC for dm-worker, just deploy it with below command: | ||
|
|
||
| {{< copyable "shell-regular" >}} | ||
|
|
||
| ``` shell | ||
| kubectl kustomize worker/base | kubectl apply -f - -n <namespace> | ||
| ``` | ||
|
|
||
| - If you need to use DM for both full and incremental data migration, you have to create PVC for dm-worker, deploy it with below command: | ||
|
|
||
| {{< copyable "shell-regular" >}} | ||
|
|
||
| ``` shell | ||
| kubectl kustomize worker/overlays/full | kubectl apply -f - -n <namespace> | ||
| ``` | ||
|
|
||
| > **Note: ** | ||
| > | ||
| > - `3` replicas are deployed by default. | ||
| > - `storageClassName` is set to `local-storage` for PVC by default. | ||
| > - If PVCs are created, they are mounted to `/data` directory. | ||

This is just for temp deployment, we may need to support DM with chart or controller later, I think we can leave it here for now.
