compute canada cvmfs-client role configuration #10

Closed WandrilleD closed 2 years ago

WandrilleD commented 2 years ago

Hi, the default configuration on the ansible-cvmfs-client role (from https://github.com/cvmfs-contrib/ansible-cvmfs-client.git) does not configure the computecanada stack properly (errors during deployments + not possible to load modules in the resulting cluster).

This is fixed simply by uncommenting line 10 of the role config file : ansible/roles/ansible-cvmfs-client/defaults/main.yml I do it with : sed 's/# - \"cvmfs-config-computecanada\"/ - \"cvmfs-config-computecanada\"/g' ansible/roles/ansible-cvmfs-client/defaults/main.yml

But I am not sure how you want to document this. Best.

I think the right approach would be to override this var in your config. e.g. add something like this to config/slurm_cluster_switch_cloud.yml

cvmfs_configuration:
#  - "cvmfs-config-default"
  - "cvmfs-config-computecanada"

I just realised it's maybe better to update this ansible task https://github.com/scicore-unibas-ch/ansible-playbook-scicore-courses-cloud/blob/master/ansible/tasks/compute_canada.yml#L16-L21 like this

- name: Configure the CVMFS client to access the ComputeCanada soft stack
  import_role:
    name: ansible-cvmfs-client
  vars:
    cvmfs_client_configure_storage: false
    cvmfs_http_proxy: "DIRECT"
    cvmfs_configuration:
      - "cvmfs-config-computecanada"
