Usage

Execute an Apache Kafka™ command

To use the CLI interface (KNetCLI) runs a command like the following:

• dotnet tool

knet -ClassToRun ConsoleConsumer --bootstrap-server SERVER-ADDRESS:9093 --topic topic_name --from-beginning

  reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Image File Execution Options\knet.exe" /v MitigationOptions /t REG_BINARY /d "0000000000000000000000000000002000" /f

• Docker image

docker run ghcr.io/masesgroup/knet -ClassToRun ConsoleConsumer --bootstrap-server SERVER-ADDRESS:9093 --topic topic_name --from-beginning

docker run masesgroup/knet -ClassToRun ConsoleConsumer --bootstrap-server SERVER-ADDRESS:9093 --topic topic_name --from-beginning

Execute an interactive shell

To use the CLI interface (KNetCLI) in interactive mode runs a command like the following:

• dotnet tool

knet -i

knet -i

• Docker image

docker run ghcr.io/masesgroup/knet -i

docker run masesgroup/knet -i

Execute in script based mode

To use the CLI interface (KNetCLI) in script based mode runs a command like the following:

• dotnet tool

knet -s path-to-script

• Docker image

docker run ghcr.io/masesgroup/knet -s path-to-script

docker run masesgroup/knet -s path-to-script

Command line switches available

knetcli needs at least ClassToRun, Interactive or Script command-line switch to identify its behavior. Here the list:

• ClassToRun: has precedence to all others and needs a second parameter which identify the command class to be executed
• Interactive (i): starts an interactive session where the user can write code like in a REPL shell, optionally can be set JarList, NamespaceList and ImportList
• Script (s): start a session to execute the script of the second parameter, optionally can be set JarList, NamespaceList and ImportList
• NoLogo (nl): do not display initial informative string
