Chapter 1. Upgrading Fuse Online
The Fuse Online upgrade process depends on whether Fuse Online is installed on Red Hat OpenShift Online or on OpenShift Container Platform (OCP).
- OpenShift Online - When Fuse 7.6 is released, the Fuse Online infrastructure on OpenShift Online is automatically upgraded. You must republish any running integrations as described in Upgrading Fuse Online integrations that are running on OpenShift Online.
- OCP - To upgrade a Fuse Online environment that is running on OpenShift Container Platform on-site, you must download the latest Fuse Online release, run the update script, and then republish any running integrations as described in Upgrading Fuse Online on OCP.
1.1. Upgrading Fuse Online integrations that are running on OpenShift Online
When Fuse 7.6 is released, the Fuse Online infrastructure on OpenShift Online is automatically upgraded. During the infrastructure upgrade, any existing integrations that are running on OpenShift Online continue to run both during and after the upgrade. However, the existing integrations continue to run with the older versions of Fuse libraries and dependencies.
After you receive an email message that lets you know that the Fuse Online infrastructure has been upgraded to the new release, upgrade your existing integrations by republishing them (not just restarting them). Do this as soon as you can.
To republish your integrations, in your Fuse Online environment, in the left navigation panel, click Integrations. Then do the following for each integration:
-
To the right of the integration entry, click
and select Edit.
- When Fuse Online displays the integration for editing, in the upper right, click Publish.
Publishing forces a rebuild that uses the latest Fuse Online dependencies.
The Fuse Online user interface shows a warning if any element of an integration has a newer dependency that needs to be updated.
1.2. Upgrading Fuse Online on OCP
To upgrade Fuse Online on OCP on-site, download the latest Fuse Online release, obtain permission to upgrade Fuse Online from a cluster administrator, and run the update script.
From time to time, fresh application images, which incorporate patches and security fixes, are released for Fuse Online. You are notified of these updates through Red Hat’s errata update channel. You can then upgrade your Fuse Online images.
The upgrade procedure for the following upgrades is the same:
- From Fuse Online 7.5 to Fuse Online 7.6
- From a Fuse Online 7.6 version to a newer Fuse Online 7.6 version
Prerequisites
You installed and are running version 7.5 of Fuse Online on OCP on-site. OR, you installed and are running a version of 7.6 of Fuse Online on OCP on-site and you want to upgrade to fresh application images.
For earlier versions:
- If you are running version 7.4 of Fuse Online on OCP, then you must upgrade to 7.5 and then you can upgrade to 7.6.
- If you are running version 7.3 of Fuse Online on OCP, then you must upgrade to 7.4 and then you can upgrade to 7.5.
- If you are running version 7.2 of Fuse Online on OCP, then you must upgrade to 7.3.
- If you are running version 7.1 of Fuse Online on OCP, then you must upgrade to 7.2.
-
You installed the
occlient tool and it is connected to the OCP cluster in which Fuse Online is installed. - You have cluster administration permissions, which are required for the first five steps in this procedure.
Procedure
A cluster administrator downloads the Fuse Online package and grants permission for a user to upgrade Fuse Online in a particular project:
Download the package containing the Fuse Online installation scripts from the following location:
https://github.com/syndesisio/fuse-online-install/releases/tag/1.9
Unpack the downloaded archive at a convenient location on your file system. The
fuse-online-install-1.9directory contains the scripts and supporting files for upgrading Fuse Online.Change to the directory that contains the extracted archive. For example:
cd fuse-online-install-1.9Log in to OpenShift with a cluster administration account, for example:
oc login -u admin -p adminChange to the OpenShift project in which Fuse Online needs to be upgraded, for example:
oc project fuse-online-projectGrant permission for upgrading Fuse Online in just this project. For example, the following command grants permission for upgrading Fuse Online to the
developeruser. After the cluster administrator runs this command, thedeveloperuser can upgrade Fuse Online in only this project, which isfuse-online-project, in this example:bash install_ocp.sh --grant developer
The user who was granted permission to upgrade Fuse Online performs the upgrade:
Log in to OpenShift, for example:
oc login -u developerSwitch to the project in which you want to upgrade Fuse Online, for example:
oc project fuse-online-projectTo check which version you are about to upgrade to, run the update script with the
--versionoption, as follows:bash update_ocp.sh --versionInvoke the update script as follows:
bash update_ocp.shTo learn more about the script, invoke
bash update_ocp.sh --help.During and after an infrastructure upgrade, existing integrations continue to run with the older versions of Fuse Online libraries and dependencies.
Upgrade Fuse Online integrations that are running as follows:
- In Fuse Online, select the integration that you want to upgrade.
- Select Edit.
- Select Publish to republish the integration.
Republishing the integration forces a rebuild that uses the latest Fuse Online dependencies.
