Description

For some strange reason the pycompss init command fails for me. I already have the compss-tutorial image 3.3. But when I launch it, it still stays open for a very long time.

So I decided to try a few things to see if I could get it to work, and at one point I think that made the code reach a function that calls start_daemon for Docker, but fails as that function does not exist on the docker/cli.py DockerCmd object (and the parent of DockerCmd is object, and I couldn't find any metaclass or something else that would define that function).

Minimal example to reproduce

1. In an environment with pycompss-cli installed
2. Run this:

$ pycompss init -n test docker -i compss/compss-tutorial:3.3
Environment created ID: test
Starting pycompss-master-test container in dir /home/bdepaula/Development/python/workspace/tutorial_apps
If this is your first time running PyCOMPSs it may take a while because it needs to download the docker image. Please be patient.

For me, this stays running forever. I had already downloaded compss/compss-tutorial:3.3, so not sure what it is doing (htop and ps didn't help, might strace it later if I don't find any other solution). But it does create the env, in another terminal:

$ pycompss env list
ID      | Type   | Active
======= | ====== | ======
default | local  | *     
test    | docker |    

Then if I change to test,

$ pycompss env change test
Environment `test` is now active

And try to start the monitor:

$ pycompss monitor start
Starting Monitor

Exception

AttributeError: 'DockerCmd' object has no attribute 'start_daemon'

Expected behaviour

The daemon is launched, I think.

For some strange reason the pycompss init command fails for me. I already have the compss-tutorial image 3.3. But when I launch it, it still stays open for a very long time.

It worked! Just took a really long time to finish (>1 hour) even though I already had downloaded the image for 3.3. I saw that when I did not specify the image, it used 3.2 by default. I wonder if it could be trying to use that image instead for some step... but anyway, feel free to ignore this part, but the start_daemon could be an issue in some other situations, I think.

When did you downloaded the image? Was it today or last week?

First thing in the morning, before joining the Zoom meeting.

Today I am using my personal laptop, which is ~10 years older than BSC's, and normally slower. But the pycompss init -n test docker -i compss/compss-tutorial:3.3 finished much quicker.

I can see the container has been up and running for some time already.

(pycompss) kinow@ranma:~$ docker image ls
REPOSITORY               TAG       IMAGE ID       CREATED        SIZE

kinow@ranma:~$ docker ps -a

I launched pycompss monitor start and it opened a webpage but failed to connect to http://localhost:8080/compss-monitor.

And I can see that the local ports/sockets were bound too:

kinow@ranma:~$ netstat -tlnp | grep -E "8888|8080"
(Not all processes could be identified, non-owned process info
 will not be shown, you would have to be root to see it all.)
tcp        0      0 0.0.0.0:8888            0.0.0.0:*               LISTEN      -                   
tcp        0      0 0.0.0.0:8080            0.0.0.0:*               LISTEN      -                   
tcp6       0      0 :::8888                 :::*                    LISTEN      -                   
tcp6       0      0 :::8080                 :::*                    LISTEN

Still, opening 8080 or 8888 doesn't work.

The container doesn't seem to have anything in its stdout for logs?

kinow@ranma:~$ docker logs 8318db7a39ef
kinow@ranma:~$ 

And opening a terminal in the container created by the pycompss-cli, it looks like there are no jupyter nor monitor running. And some weird files inside the root of the container as well.

kinow@ranma:~$ docker exec -ti 8318db7a39ef /bin/bash
root@8318db7a39ef:/# netstat -tlnp
bash: netstat: command not found
root@8318db7a39ef:/# ps

And the Jupyter command fails:

(pycompss) kinow@ranma:~$ pycompss jupyter
