# Migration Toolkit for Containers Operator
2+
3+
This is to deploy the [Migration Toolkit for Containers Operator](https://docs.redhat.com/en/documentation/openshift_container_platform/4.18/html/migration_toolkit_for_containers/about-mtc) to OpenShift. The Migration Toolkit for Containers (MTC) enables you to migrate stateful application workloads between OpenShift Container Platform 4 clusters at the granularity of a namespace.
4+
5+
The Migration Toolkit for Containers Operator is a "Rolling Stream" Operator, meaning updates are available asynchronously of OpenShift Container Platform releases. For more information, see OpenShift Operator Life Cycles on the Red Hat Customer Portal.
6+
7+
Do not use the `base` directory directly, as you will need to patch the `channel` based on the version of OpenShift you are using, or the version of the operator you want to use.
8+
9+
The current *overlays* available are for the following channels:
10+
11+
* [release-v1.8](operator/overlays/release-v1.8)
12+
* [release-v1.7](operator/overlays/release-v1.7)
13+
14+
## Usage
15+
16+
If you have cloned the `gitops-catalog` repository, you can install operator based on the overlay of your choice by running from the root (`gitops-catalog`) directory.
17+
18+
```
19+
oc apply -k migration-toolkit-containers/operator/overlays/<channel>
20+
```
21+
22+
Or, without cloning:
23+
24+
```
25+
oc apply -k https://github.com/redhat-cop/gitops-catalog/migration-toolkit-containers/operator/overlays/<channel>
26+
```
27+
28+
As part of a different overlay in your own GitOps repo:
29+
30+
```
31+
apiVersion: kustomize.config.k8s.io/v1beta1
32+
kind: Kustomization
33+
resources:
34+
- https://github.com/redhat-cop/gitops-catalog/migration-toolkit-containers/operator/overlays/<channel>?ref=main

```
