* - Application name
|
||
- Description
|
||
|
||
* - | `Zabbix Agent`_
|
||
- Zabbix Agent is a simple application. It doesn’t deploy a VM by itself,
|
||
but is installed on a specific VM that may contain any other
|
||
applications. This VM is tracked by Zabbix and by its configuration.
|
||
|
||
So Murano performs the Zabbix agent configuration based on the user
|
||
input. The user chooses the way of instance tracking - HTTP or ICMP that may
|
||
perform some modifications in the application package.
|
||
|
||
It is worth noting that application scripts are written in Python, not
|
||
in Bash as usual. This application does not work without Zabbix server
|
||
application since it’s a required property, determined in the
|
||
application definition.
|
||
|
||
* - | `Zabbix Server`_
|
||
- Zabbix Server application interacts with Zabbix Agent by calling its
|
||
setUpAgent method and providing information about itself: IP and hostname
|
||
of VM on which the server is installed.
|
||
|
||
Server installs MySQL database and requests database name, password and
|
||
some other parameters from the user.
|
||
|
||
* - | `Docker Crate`_
|
||
- This is a good example on how difficult logic may be simplified with
|
||
the inheritance that is supported by MuranoPL. Definition of this app is
|
||
simple, but the opportunity it provides is fantastic.
|
||
|
||
Crate is a distributed database, in the Murano Application catalog it
|
||
looks like a regular application. It may be deployed on Google Kubernetes
|
||
or regular Docker server. The user picks the desired option while filling in
|
||
the form since these options are set in the UI definition. The form field
|
||
has a list of possible options::
|
||
|
||
...
|
||
type:
|
||
- com.mirantis.docker.kubernetes.KubernetesPod
|
||
- com.mirantis.docker.DockerStandaloneHost
|
||
|
||
Information about the application itself (docker image and port that is
|
||
needed to be opened) is contained in the getContainer method. All other
|
||
actions for the application configuration are located at the
|
||
DockerStandaloneHost definition and its dependencies. Note that this
|
||
application doesn’t have a filename:Resources folder at all since the
|
||
installation is made by Docker itself.
