How to execute command on running container?

[PugachA]

I want execute custom sh commands on running containers.
Example:

docker exec -it bced6a23bd7f echo "Hello world"

I haven't found a way to do this. Can you tell me?

Hi @PugachA, you can run a command on a container using the Execute command.

💡 Below sample will output: The command was executed successfully:

using (
    var container =
        new Builder().UseContainer()
            .UseImage("postgres:9.6-alpine")
            .ExposePort(5432)
            .WithEnvironment("POSTGRES_PASSWORD=mysecretpassword")
            .WaitForPort("5432/tcp", 30000)
            .Build()
            .Start())
{

  var config = container.GetConfiguration(true);

  // Run the *echo* command inside the running container
  var output = container.DockerHost.Execute(
                                config.Id,
                                "echo \"I'm inside the container\"",
                                container.Certificates);

  if (output.Data.Contains("I'm inside the container"))
  {
    Console.WriteLine("The command was executed successfully");
  }
  else
  {
    Console.WriteLine("The command was not executed successfully");
  }

}

Cheers,
Mario 😊
