#1653 implementation get version and get edition docker

[hkosim]

This PR fixes #1653

Implemented changes:

• getVersion() and getEdition() for Docker as well as kubectl is now working properly on Windows and Linux.

Note:

• The functionalities has been tested on Windows and Linux using Hyper-V.
• The used commands to check Docker Desktop version are:

OS	Exec.	Details	Full Commands
Windows	cmd	through reg and checks for installation in windows registry	reg query "HKLM\SOFTWARE\Microsoft\Windows\CurrentVersion\Uninstall\Docker Desktop" /v DisplayVersion
Linux	bash	through apt and filtered using grep	apt list --installed | grep docker-desktop | awk '{print $2}'

• There are however some alternatives using different Terminals that could be used if the above implemented version are not working as intended.

OS	Exec.	Details	Full Commands
Windows	powershell	Get-CimInstance	Get-CimInstance -ClassName CIM_DataFile -Filter "Name='C:\Program Files\Docker\Docker\Docker Desktop.exe'"
Linux	dpkg	debian package	dpkg -l | grep docker-desktop | awk '{print $3}'
MacOS (Not yet tested)	brew	Homebrew - additional package manager for MacOS	brew list --cask docker --versions | awk '{print $2}'

Pseudocode:

FUNCTION getInstalledVersion():

IF isRancherDesktopInstalled() THEN
        RETURN getRancherDesktopClientVersion()
    ELSE
        osType ← context.getSystemInfo().getOs()

        SWITCH osType
            CASE WINDOWS:
                parsedVersion ← getDockerDesktopVersionWindows()
            CASE LINUX:
                parsedVersion ← getDockerDesktopVersionLinux()
            DEFAULT:
                parsedVersion ← null
        END SWITCH

        IF parsedVersion IS null THEN
            context.error("Couldn't get installed version of " + getName())
        END IF

        RETURN parsedVersion
    END IF
END FUNCTION

FUNCTION getInstalledEdition():

    IF NOT isDockerInstalled() THEN
        context.error("Couldn't get installed edition of " + getName())
        RETURN null
    END IF

    IF isRancherDesktopInstalled() THEN
        RETURN "rancher"
    ELSE
        RETURN "desktop"
    END IF
END FUNCTION

Findings about Testcases

Testcases was not yet implemented correctly. The idea that has been tested:

What could work:

1. Setting up DockerTest.java with path for mocked rdctl and bash path* on custom environment.properties (*hard-coded) .
   -> getVersion() is working properly.

Still in progress:
Mocking cmd and reg for checking DockerDesktop version.

• mocking windows executable requires custom or external tools
• Not yet tested: reg might also be mocked with file with .cmd extension.
