Server Setup

Instructions

  1. SSH into Hypervisor

  2. use Git to clone this repository and move into the terraform directory

  3. Run the following 3 commands:

    • terraform init
    • terraform plan
    • terraform apply
  4. Navigate to the ansible directory

  5. run setup target from Makefile

  6. Use ansible to setup hub using the commands that would be equivalend to

    • make ansible/setup > gets external roles
    • make hub/init > updates kernel
    • make hub/apply > builds JupyterHub (this is the step we are iterating over
  7. ansible hub - iterate here until ltiauth is working

eventually terraform state file needs to live in an S3 bucket

ssh stty2u@<hypervisor address>
virsh list
virsh domifaddr <name>

ls ../keys/id_syzygy_stat
ssh -i <ip addr of hub>

To Check

  • Is the pre-spawn hook defined in the correct place?

    ansible/roles/internal/jupyterhub/templates/jupyterhub_config_base.py.j2
    
  • Do we need to use this for the hub_ip?

    from jupyter_client.localinterfaces import public_ips
    c.JupyterHub.hub_ip = public_ips()[0]
  • Is pycurl isntalling correctly?

If not:

sudo yum install python36u-devel openssl-devel
PYCURL_SSL_LIBRARY=openssl sudo -E pip3.6 install pycurl
  • Did I set the Apache proxy header correctly?

      <Location /jupyter>
        ProxyPass http://127.0.0.1:8000/jupyter
        ProxyPassReverse http://127.0.0.1:8000/jupyter
        ProxyPreserveHost on
        RequestHeader set X-Forwarded-Proto "https"
      </Location>
    
  • Should we update and upgrade git? Yes!

  • To specify at runtime:

    • Canvas API Token

    • LTI Consumer Key

    • LTI Consumer Secret

    • put it in a file that is in the same place as the ssh keys

  • Can we specify the course name?

    • incorporate course name into zfs role
    • store as host or group variable (list of courses we will have)
    • example: see local_vars.yml (we could encrypt this...)
  • Is ltiauthenticator installing?

    Is this yaml file being sourced, and if not, how would it be?

    ansible/roles/internal/ltiauthenticator/main.yml
    

Grading Server:

pip install rudaux
pip install nbgrader

sudo jupyter nbextension install --sys-prefix --py nbgrader --overwrite
sudo jupyter nbextension enable --sys-prefix --py nbgrader
sudo jupyter serverextension enable --sys-prefix --py nbgrader

Rebuilding the environment

Here are temporary instructions for rebuilding the hub and marker environments from scratch

  $ cd dsc100-infra-ian/terraform/prod
  $ terraform init
  $ terraform plan
  $ terraform apply
  $ cd ../../ansible/
  $ make env=prod hub/init
  $ make env=prod hub/apply
