perfSONAR User Q&A and Other Discussion

[Dan Doyle <>]

Is the host parent running apache? If so, stop it and restart the container. There are some more docs forthcoming, but the tldr is that the docker container on linux is going to share the network stack directly with the host OS. Meaning that the docker container's pscheduler is going to want to bind to 443 directly, and if the host is already running apache you will end up in a peculiar state where requests are actually hitting the host's apache, not the docker container's.

Hello,

I am using this OS:

# cat /etc/debian_version
7.11
# uname -an
Linux monipe-bc 3.16.0-0.bpo.4-amd64 #1 SMP Debian 3.16.39-1+deb8u1~bpo70+1 (2017-02-24) x86_64 GNU/Linux

We have some old mini PCs running Debian 7 and we will try to run docker in it using the perfsonar/testpoint image.

Could it be something related to the host OS?

Regards,

Hi Murilo,

Thanks for trying out the new Docker containers, sorry to hear you're having trouble. What is the host operating system in this case?

Hi,

As I notice, perfSONAR is starting to support Docker. I tried to run perfsonar/testpoint image, like below:

# docker run --privileged -d -P --net=host -v "/var/run" perfsonar/testpoint

Container is up and running, but when I try to run on task, it is coming with the following errors:

# docker exec -it kind_morse bash

[root@monipe-bc /]# pscheduler task rtt www.ufsc.br
Unable to find pScheduler on localhost

[root@monipe-bc /]# pscheduler ping localhost
localhost: SSL not available.

[root@monipe-bc /]# pscheduler debug on
curl: (35) SSL received a record that exceeded the maximum permissible length.

[root@monipe-bc /]# pscheduler ping 200.X.X.X
200.X.X.X: SSL not available.

It looks like a certificate problem. How could I resolve it?

Regards,
