OpenShift Migration Plugin

Kinds of Plugins

Velero currently supports the following kinds of plugins:

• Backup Item Action - performs arbitrary logic on individual items prior to storing them in the backup file.
• Restore Item Action - performs arbitrary logic on individual items prior to restoring them in the Kubernetes cluster.

Building the plugins

To build the plugins, run

$ make

To build the image, run

$ make container

This builds an image tagged as docker.io/konveyor/openshift-migration-plugin. If you want to specify a different name, run

$ make container IMAGE=your-repo/your-name:here

Deploying the plugins

To deploy your plugin image to an Velero server:

1. Make sure your image is pushed to a registry that is accessible to your cluster's nodes.
2. Run velero plugin add <image>, e.g. velero plugin add quay.io/konveyor/migration-plugin

Modified version of dep needed

At this point, the latest dep release does not support dependencies which use go modules. Since this plugin has dependencies which use go modules, a custom build of dep based on an open PR which adds go modules support is required. To build dep with go modules support, run

go get -d -u github.com/golang/dep
cd $(go env GOPATH)/src/github.com/golang/dep
git fetch origin +refs/pull/1963/merge
git checkout FETCH_HEAD
go install ./cmd/dep
