The static methods in the new class `eu.nebulouscloud.optimiser.kubevela.KubevelaAnalyzer` are used by multiple components in the NebulOuS Solver. Create a library `nebulous-requirements-extractor` that houses this class. Adapt the container build job to run at project root, not inside the `nebulous-controller` subdirectory. Add jobs for library build and repository upload. Change-Id: Ic61c7064d216201031659bc362e3ed218f9c2b67

# The NebulOuS optimizer controller
|
|
|
|
This module serves two purposes:
|
|
|
|
- When a new NebulOuS application is started, set up the initial optimizer
|
|
infrastructure, parse the application structure and metric model, and pass
|
|
an initial resource configuration (“Optimized Service Graph”) to the
|
|
Deployment Manager.
|
|
|
|
- When an application is running, monitor the application-specific metrics
|
|
coming in via ActiveMQ and invoke the optimizer as needed, thereby possibly
|
|
triggering application reconfigurations.
|
|
|
|
# Building
|
|
|
|
To compile, install a JDK (Java Development Kit) version 17 or greater on the build machine.
|
|
|
|
```sh
|
|
# Compile:
|
|
./gradlew assemble
|
|
# Compile and test:
|
|
./gradlew build
|
|
```
|
|
|
|
# Building the container
|
|
|
|
A container can be built and run with the following commands:
|
|
|
|
```sh
|
|
docker build -t optimiser-controller -f Dockerfile .
|
|
docker run --rm optimiser-controller
|
|
```
|
|
|
|
# Running
|
|
|
|
To run, install a JRE (Java Runtime Environment) version 17 or greater.
|
|
|
|
A successful build creates the jar file `dist/optimiser-controller-all.jar`.
|
|
This file is self-contained and can be executed via the following command:
|
|
|
|
```sh
|
|
java -jar optimiser-controller/dist/optimiser-controller-all.jar
|
|
```
|
|
|
|
## Running in jshell
|
|
|
|
The command `./gradlew --console plain jshell` opens a REPL (read-eval-print
|
|
loop) with the package `eu.nebulous.optimiser.controller` pre-imported. On
|
|
the REPL, one can write Java snippets such as:
|
|
|
|
```java
|
|
SalConnector conn = new SalConnector(new URI("http://localhost:8088"));
|
|
conn.isConnected();
|
|
```
|
|
|
|
For command-line editing and history support, use the `rlwrap` command:
|
|
`rlwrap ./gradlew --console plain jshell`.
