Devfile mode: the run command process isn't killed, before starting the debug command process, if 'restart' attribute is set as false

[devang-gaur]

Pre requisite knowledge :

the restart attribute, as illustrated here , enables (when set as true) or disbles (when set as false) the retriggering of a project's build cycle inside the deployed container when odo push is used and newly added or edited files are pushed inside the running app container.

Case when restart attribute to set as true

Using a nodejs project while using the nodejs devfile from the default registry

https://github.com/odo-devfiles/registry/blob/78f685b7476791d9e45a0c9d6bbb8398b93d0216/devfiles/nodejs/devfile.yaml

if you see the logs here, it is ensured that the running commands are forcefully killed before the debug command is started.

Case when restart attribute to set as false

Using a quarkus project while using this devfile.

if you see the logs here, the process started by the run command is not killed before starting the debug command process.

This leads to an error as the port occupied from the run command is not released for the debug command to start properly.

BUT

When I set the restart attribute as true, the ongoing processes are killed before the debug command starts. Check the logs...
