Migrating applications from Murano v0.5 to Stable/Juno
|
|
======================================================
|
|
|
|
Applications created for Murano v0.5, unfortunately, are not suported in Murano
|
|
stable/juno. This document provides the application code changes required for
|
|
compatibility with the stable/juno Murano version.
|
|
|
|
Rename *'Workflow'* to *'Methods'*
|
|
----------------------------------
|
|
|
|
In stable/juno the name of section containing class methods is renamed to
|
|
*Methods*, as the latter is more OOP and doesn't cause confusion with Mistral. So,
|
|
you need to change it in *app.name/Classes* in all classes describing workflow
|
|
of your app.
|
|
|
|
For example:
|
|
|
|
::
|
|
|
|
Workflow:
|
|
deploy:
|
|
Body:
|
|
- $._environment.reporter.report($this, 'Creating VM')
|
|
|
|
Should be changed to:
|
|
|
|
::
|
|
|
|
Methods:
|
|
deploy:
|
|
Body:
|
|
- $._environment.reporter.report($this, 'Creating VM')
|
|
|
|
Change the Instance type in the UI definition 'Application' section
|
|
-------------------------------------------------------------------
|
|
|
|
The Instance class was too generic and contained some dirty workarounds to
|
|
differently handle Windows and Linux images, to bootstrap an instance in a
|
|
number of ways, etc. To solve these problems more classes were added to the
|
|
*Instance* inheritance hierarchy.
|
|
|
|
Now, base *Instance* class is abstract and agnostic of the desired OS and agent
|
|
type. It is inherited by two classes: *LinuxInstance* and *WindowsInstance*.
|
|
|
|
- *LinuxInstance* adds a default security rule for Linux, opening a standard
|
|
SSH port;
|
|
|
|
- *WindowsInstance* adds a default security rule for Windows, opening an RDP
|
|
port. At the same time WindowsInstance prepares a user-data allowing to use
|
|
Murano v1 agent.
|
|
|
|
*LinuxInstance* is inherited by two other classes, having different software
|
|
config method:
|
|
|
|
- *LinuxMuranoInstance* adds a user-data preparation to configure Murano
|
|
v2 agent;
|
|
|
|
- *LinuxUDInstance* adds a custom user-data field allowing the services to
|
|
supply their own user data.
|
|
|
|
You need to specify the instance type which is required by your app. It
|
|
specifies a field in UI, where user can select an image matched to the instance
|
|
type. This change must be added to UI form definition in *app.name/UI/ui.yaml*.
|
|
|
|
For example, if you are going to install your application on Ubuntu, you need to
|
|
change:
|
|
|
|
::
|
|
|
|
Application:
|
|
?:
|
|
instance:
|
|
?:
|
|
type: io.murano.resources.Instance
|
|
|
|
to:
|
|
|
|
::
|
|
|
|
Application:
|
|
?:
|
|
instance:
|
|
?:
|
|
type: io.murano.resources.LinuxMuranoInstance
|
