Ceph Version Upgrade: Air-gapped Environment

In a previous article, we demonstrate how to upgrade Ceph versions. There, we assume that Internet connection is available. This article shows how to upgrade a Ceph in an air-gapped environment. The environment we use for this article is described in the air-gapped deployment article.

We will upgrade from Ceph Quincy (specific version: v17.2.5) to Ceph Reef (specific version 18.2.2).

To check available versions, we used the following command.

sudo ceph orch upgrade ls

As shown below, the command will fail since it tries to connect to https://quay.io/v2/ceph/ceph/tags/list.

Error message from querying available upgrade versions

The normal upgrade command will fail as well.

Status of failed upgrade attempt due to an inaccessible image

By running stop command, we can stop upgrade.

sudo ceph orch upgrade stop

Preparation

We need two preparations: putting necessary images into a private repository and turning some OSD operations off.

Container Image Preparation

The following table shows the default images for both versions.
