[Ubuntu] how to run docker and redirect the output of docker using qt qprocess?

[corehaha]

I want to run several commands and scripts in docker using qprocess. And redirecting the output of docker to qplaintext.But there is no result. Looking for help ! So how to run docker and redirect the output ????
Here is my command list:

command_list_<<"sh docker/scripts/dev_into.sh"<<"cyber_recorder record -a";

docker/scripts/dev_into.sh is a script which get into my docker container

cyber_recorder is a command existed in this container

and using code following , my program can run command one by one;

    void(QProcess:: *finished)(int) = &QProcess::finished;
    connect(this->process,finished,this,[=](){
        if(!br->command_list().isEmpty())
        {
            process->start(command_list_.at(0));
            command_list_.removeFirst();
        }
    });

Ps. Using qprocess to run echo $USER, the result is not my hostname ,but$USER.

Hi,

Did you connect the QProcess::readyReadStandardOutput ? And use QProcess::readAllStandardOutput to read it ?

You might want to do as well for the error channel.

I've use readAll to read channel .

    connect(this->process,&QProcess::readyRead,this,[=](){

        QString result_ = process->readAll();
        todlg->pte->appendPlainText(result_);

    });

The problem now is I cannot get into docker using qprocess.Except I use qprocess to run gnome-terminal and indirectly into docker .

Please share your code. It's just guesswork at this point.

@SGaist Using qprocess I've solved by executing the shell script instead of single command. Thank you anyway !!!!

@corehaha said in [Ubuntu] how to run docker and redirect the output of docker using qt qprocess?:

command_list_<<"sh docker/scripts/dev_into.sh"<<"cyber_recorder record -a";

You may try this out.

QStringList arguments;
arguments<< "docker/scripts/dev_into.sh"
<<"cyber_recorder"
<< "record"
<< " -a";
process->start( QString( "/bin/sh" ), arguments );
