Overview

ftl-injector clones the FTL Repo into an existing environemnt and configures the target machine to be able to grade labs. Originally designed to work with AgnosticD FTL can work with any environment where the appropriate Ansible credentials can be supplied.

What does ftl-injector do:

1. Create grading virtualenv - isolating FTL from student configuration

2. Clones the FTL Repo, containing graders etc onto the grader host

3. Create custom facts about students, course(s), for simple reporting

4. Installs grader scripts etc.

Usage

1. Add FTL to your config by

   • Choosing a grader host where FTL will be installed, typically a machine a student works on.

     • bastion

     • Some form of client VM

   • Calling the ftl-injector role

     • For example config three-tier-app adds in in pre_software.yml

       - name: Inject and configure FTL on bastion as grader host
         hosts: bastions
         become: true
         roles:
           - ftl-injector
         tags:
           - step004
           - ftl-injector

2. OPTIONAL To provide accurate reporting provide a student_login var

   • For agnosticd users working with CloudForms, in your deployer scripts:

     export OPENTLC_STUDENT=${USER:-unknown-student}                   (1)
     
     
                 ansible-playbook                                  \
                     ${DEPLOYER_REPO_PATH}/main.yml                \
                     -e ANSIBLE_REPO_PATH=${DEPLOYER_REPO_PATH}    \
                     -e guid=${GUID}                               \
                     -e env_type=${ENVTYPE}                        \
                     -e key_name=${KEYNAME}                        \
                     -e email=${USEREMAIL}                         \
                     -e student_login=${OPENTLC_STUDENT}           \   (2)

     • 1 Assign the CloudForms --user argument to an ENV VAR

     • 2 Use 1 to pass to ansible via -e

Note	Failing to do this will NOT result in failure as student_login defaults to john-doe in the the roles defaults/main.yml.

Notes

Adding, or updating, the ftl-injector role to your project:

1. Create a requirements.yml, with the correct version tag:

   ---
   # External role to setup grader host virtualenv and FTL grading infra
   
   - src: https://github.com/redhat-gpte-devopsautomation/ftl-injector
     name: ftl-injector
     version: v0.5

   Use ansible-galaxy to install, (substituting your roles directory path if necessary).

   ansible-galaxy install -r requirements.yml -p roles
