perfSONAR User Q&A and Other Discussion

[Andrew Lake <>]

Hi Johann,

Mostly just ack'ing this so you don’t get complete radio silence. The dev team is still trying to fill an expertise gap on the PWA and right now don’t have immediate answer to your questions. Clearly the container is having some trouble finding a few python modules and the mentioned script, so not sure if there is a problem with the build or something else. We’re trying to figure out how to best handle this request, but didn’t want to leave you completely hanging in meantime. If you are able to get these sorted on your own let us know, and sorry we don’t have a quick solution for you at the moment.

Thanks,

Andy

I decided to switch from RPM packages to try the Docker PWA route.

I first tried the docker-compose route using this script, but it's giving a lot of errors:

wget -4 https://raw.githubusercontent.com/perfsonar/psconfig-web/master/psconfig-web-admin/perfsonar-psconfig-web-admin/deploy/docker/docker-compose.yml

docker-compose up

    import strict_rfc3339

ModuleNotFoundError: No module named 'strict_rfc3339'

During handling of the above exception, another exception occurred:

    @_checks_drafts("date-time", raises=(ValueError, isodate.ISO8601Error))

AttributeError: module 'isodate' has no attribute 'ISO8601Error'

I then switched to using the docker scripts: 

Running /usr/local/sbin/update_pwa_containers.sh downloads all the images, but gives this error at the end.

/usr/local/sbin/update_pwa_containers.sh: line 31: ./start_pwa_containers.sh: No such file or directory

Running the script manually starts all the containers, except for the an error with mongo :

/usr/local/sbin/start_pwa_containers.sh

/usr/bin/docker-current: Error response from daemon: SELinux relabeling of /usr/local/docker/volumes/d69b41dc7fe2f46b7f6b430b85e2855e2d599421c328d67d447caf449f875f26/_data is not allowed: "Relabeling content in /usr is not allowed."

Creating the mongo container manually gives the same error:

docker run \

>         --net pwa \
>         --name mongo \
>         -v /usr/local/data/mongo:/data/db \

Hi Johann,

Indeed links are not correct. Please see correct links below and we'll correct web pages

Also for some reason downloading over IPv6 semms to not work so please use v4 switch and it works then.

Hi

I'm trying to get a new PWA server running, but no success. Some of the links in the documentation don't work.

https://docs.perfsonar.net/pwa_install_docker.html

 - wget https://github.com/perfsonar/psconfig-web/raw/master/deploy/docker/pwa.sample.tar.gz

wget -4 https://github.com/perfsonar/psconfig-web/raw/master/psconfig-web-admin/perfsonar-psconfig-web-admin/deploy/docker/pwa.sample.tar.gz

https://docs.perfsonar.net/pwa_docker_create.html

- wget https://raw.githubusercontent.com/perfsonar/psconfig-web/master/deploy/docker/docker-compose.yml

wget -4 https://raw.githubusercontent.com/perfsonar/psconfig-web/master/psconfig-web-admin/perfsonar-psconfig-web-admin/deploy/docker/docker-compose.yml

https://docs.perfsonar.net/pwa_install_rpm.html

- rpm -hUv http://software.internet2.edu/rpms/el7/x86_64/latest/packages/perfSONAR-repo-0.10-1.noarch.rpm

refer to repos installation mentioned here: https://docs.perfsonar.net/install_el.html

On https://docs.perfsonar.net/pwa_install_rpm.html , this paragraph seems to be misplaced:

- Before you start the docker engine, you might want to add any VM specific configuration. For example, your VM might be using /usr/local as a primary partition for your VM.

I've made some progress by installing PWA using RPM packages. 

- systemctl status httpd perfsonar-psconfig-web-admin-* shows all the daemons are up and running (httpd was not enabled by default). 

- The only changes I made to the default configs was changing the hostname in /etc/perfsonar/psconfig-web/index.js and /etc/perfsonar/psconfig-web/auth/index.js.

 - I've also added a local PWA user with super-admin rights using "pwa_auth useradd" + "pwa_auth modscope". 

http://pwa-test.sanren.ac.za/ loads the default Apache html page and http://pwa-test.sanren.ac.za/pwa/pub gives a Not Found. 

- Do I need to configure anything in the pwa*.conf files in /etc/httpd/conf.d/ 

- Where can I view the log files for PWA

Regards,
