Historia de usuario: https://ognproject.evlt.uma.es/redmine/issues/494

Preparar el entorno

Ejecutar una VM linux, windows o macos (por ejemplo con virtualbox, docukrr o qemu).

Crear paquete de ogagent-1.3.4 (wiki redmine). Subirlo a la VM e instalarlo.

Configurar IP del ogserver de mentira (usar la IP del portátil de uno):

# sed -i -e '/^remote=/s/192.168.2.10/192.168.1.249/' /usr/share/OGAgent/cfg/ogagent.cfg

Ejecutar ogserver de mentira:

$ sudo perl -MDateTime -Mojo -E 'a("/*foo" => sub { printf "%s %s %s %s\n", DateTime->now->strftime ("%Y%m%d %H%M%S%z"), $_->tx->remote_address, $_->param("foo"), $_->req->body; $_->render (text => "{}") })->start ("daemon", "-l", "https://192.168.1.249:443")'

Reiniciar la VM y comprobar que el agente arranca.

Subir a la VM un script que tarde un tiempo en ejecutarse. Llamarlo printer.py. Por ejemplo este:

import time
import sys
import random
r=random.random()

def _out(txt,zzz=3):
    sys.stdout.write("{} {}".format(r,txt))
    sys.stdout.flush()
    time.sleep(zzz)

def _err(txt,zzz=3):
    sys.stderr.write("{} {}".format(r,txt))
    sys.stderr.flush()
    time.sleep(zzz)

_out ("Hello\n")
_out ("World!\n")
_err ("That's\n")
_out ("Actually,\n")
_err ("an error\n")
_out ("I'm fine\n")

Exportar un par de variables para que el PR sea más fácil de seguir:

$ export CLI_IP=192.168.1.43
$ export TOKEN=elquesea

Ejecutar pwd en el lado de sistema

$ curl --insecure -X POST --header "Authorization: $TOKEN" --data '{"script":"'$(echo pwd |base64 -w 0)'","client":"false"}' https://$CLI_IP:8000/opengnsys/script
{"op": "launched", "jobid": "cc7707b2"}

Para obtener la lista de trabajos hay que llamar a preparescripts, esperar un poco y llamar a getscripts:

$ curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/preparescripts; sleep 1.2; curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/getscripts |jq .

    "stdout": "/\n",
    "stderr": "",
    "jobid": "cc7707b2",
    "rc": 0
  }
]

Ejecutar pwd en el lado de usuario

$ curl --insecure -X POST --header "Authorization: $TOKEN" --data '{"script":"'$(echo pwd |base64 -w 0)'","client":"true"}' https://$CLI_IP:8000/opengnsys/script
{"op": "launched"}

Debido a la arquitectura asíncrona del agente, el jobid no está inmediatamente disponible y no sale en la salida de la llamada a /script.

Consultar jobs:

$ curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/preparescripts; sleep 1.2; curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/getscripts |jq .

Ejecutar dos instancias del printer.py en paralelo

$ curl --insecure -X POST --header "Authorization: $TOKEN" --data '{"script":"'$(echo python3 /home/nati/printer.py |base64 -w 0)'","client":"true"}' https://$CLI_IP:8000/opengnsys/script

{"op": "launched"}

Consultarlos varias veces y ver el progreso:

  • stdout y stderr se van actualizando
  • cuando cada trabajo termina, status cambia a finished y aparece el rc
$ curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/preparescripts; sleep 1.2; curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/getscripts |jq .

El "rc": -15 indica SIGTERM, es lo que tiene que salir. También tenemos stdout y stderr incompletos, lo cual indica que el proceso no terminó.

Funciona todo según lo esperado.

El id del job, ya aparece con 12 caracteres.

Lo único que he notado, es que he tenido que subir el sleep a 3 segundos, no me funcionaba con 1.2s ni con 2s

curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/preparescripts; sleep 3; curl --insecure -X GET --header "Authorization: $TOKEN" https://$CLI_IP:8000/opengnsys/getscripts |jq .

Validado también en MacOS, todo OK.
