Export and Import uDeploy Component or Application

Sometimes it might be useful to export resources like Components or Applications from a uDeploy installation and import to another one.

Let’s see how to do it and what problem we could deal with:

First of all let’s export our Component.

Click “Actions” beside the Component, then  click “Export“.

Save your .json file

In the other uDeploy installation,  go to Components, click  the “Import Components” button and upload the .json file exported before.

At this point you could receive an import error.

Watch the uDeploy Server log. Can you see something like this?

Property Priority Order of precedence

If a uDeploy property is defined in multiple places, its value is determined by the property priority or order of precedence. The following list defines the order of precedence from highest to lowest:

– Process
– Component version
– Resource
– Agent
– Environment
– Component
– Application
– System

If you have an environment property named ${p:environment/app.url} and a resource property with the same name, you can refer to the resource property by using ${p:app.url} or ${p:resource/app.url}.

Because the resource property is higher on the order of precedence than the environment property, in this case you must refer to the environment property by using the scoped format: ${p:environment/app.url}.

Anyway if you have a Replace Tokens Step, priority depends on the order of the Property List . Let’s suppose to have an environment property and an agent property with same name: hostname.fqdn

If Property List is like:

${p:environment/allProperties},${p:agent/allProperties}

agent property will win.

If Property List is like:

${p:agent/allProperties},${p:environment/allProperties}

environment property will win.
