ForemanSnapshotManagement

ForemanSnapshotManagement is a Foreman plugin to manage snapshots. As Hypervisor the following systems are supported:

• VMware vSphere
• Proxmox

• List existing snapshots of a virtual machine.
• Create a snapshot of a virtual machine.
• Revert existing virtual machines to a previously created snapshot.
• Remove existing snapshots of a virtual machine.

You can install Foreman Snapshot Management plug-in using foreman-installer. For more information, see Installing the Snapshot Management Plug-in in Foreman documentation.

You will get a new tab named "Snapshots" in the hosts page in Foreman.

Following rights are required to view snapshots:

• Snapshot Viewer
• Viewer

Following additional rights are required for creating, modifying, deleting and rollback:

• Snapshot Manger
• Site Manager

Documentation for the api v2 endpoints provided by this Plugin can be found at https://<your.foreman.installation>/apidoc/v2/snapshots.html. Some examples using curl and jq are given here.

The api user requires the same rights as a normal one.

Environment variables used in this examples, edit to your needs.

This updates only name and description, not the data.

curl -s -u "$AUTH" \
    -X PUT \
    -H 'Accept: application/json' \
    -H 'Content-Type: application/json' \
    --data "{ \"name\": \"${SNAP_NAME}\", \"description\": \"${DESCRIPTION}\" }" \
    "https://${FOREMAN}/api/v2/hosts/${HOST}/snapshots/${SNAP_ID}" \
    | jq

{
  "description": "An exceptional snapshot.",
  "id": "snapshot-666",
  "name": "exceptional",
  "created_at": "2018-10-19 07:11:24 UTC",
  "parent_id": null,
  "children_ids": []
}

This request will block until the snapshot is reverted. Make sure to check your timeouts.

curl -s -u "$AUTH" \
    --max-time 600 \
    -X PUT \
    -H 'Content-Type: application/json' \
    -H 'Accept: application/json' \
    "https://${FOREMAN}/api/v2/hosts/${HOST}/snapshots/${SNAP_ID}/revert" \
    | jq

  "name": "test",
  "created_at": "2018-10-18 09:50:03 UTC",
