Molecule tests v0.1

[lhoss]

Howto run:

# ps: ansible >2.8.2 works fine also (but not 2.9.0, see the README)
pip2 install ansible==2.9.1 
pip2 install molecule==2.22

# simple cmd
cd <repo base folder>
molecule test

# the same, but avoid the 'destroy' (if something fails for ex.):
molecule test --destroy=never --scenario-name default

Early version Notes:

• the whole playbook runs through
  • but the CM 'template import' action is still running (on my 1. full try, not sure if my 16GB Macbook has enough memory/resources for this config to complete)
• to run as non root/sudo user, I had todo a small patch (see below), I will create a separate PR for that
• Test inspired by similar molecule config I did for HDP deployments in Initial Molecule tests (to deploy a single-node HDP3 cluster) hortonworks/ansible-hortonworks#175

TODOs

• travis build
  • try with suited small CDH host_templates (that allow a CDH cluster install with the 7.5GB VM memory limit of travis, free tier)
• more tests
• multi nodes installs
• test matrix for various versions, DBs , etc

to run the ansible deployment as non root/sudo user, p.eg on your local PC/Mac, with Molecule:
patch_diff__disable_need_for_local_sudo.patch.txt

I added a simple .travis file , but WIP to get till the CM deploying a cluster.
Current build iterations

• build °1: just an intermittent pip repo download issue (it seems)
• build °2: issue with the delegate_to: localhost task (that I patched above), which also fails in travis (for another reason, than the 'sudo' prompt on my local notebook)
• build °3: build (https://travis-ci.com/scigility/cloudera-playbook/builds/139780029)
  • fixed by "pip install jmespath"
  • orig error:

# the task after "Discover product versions from parcel manifests"
    TASK [cdh : set_fact] **********************************************************
    fatal: [centos7-cdh01.local]: FAILED! => {"msg": "You need to install \"jmespath\" prior to running json_query filter"}

• build °4 (https://travis-ci.com/scigility/cloudera-playbook/jobs/264141299), now runs till last step 👍 , just then fails in the wait loop check:

TASK [cdh : Wait for import cluster template command to complete] **************
...
FAILED - RETRYING: Wait for import cluster template command to complete (8 retries left).
    fatal: [centos7-cdh01.local]: FAILED! => {"msg": "The conditional check 'not result.json.active' failed. The error was: error while evaluating conditional (not result.json.active): 'dict object' has no attribute 'json'"}

Updated my branch:

• re-based my molecule_tests branch with latest master
  • including fix for missing "jmespath" python module
• that includes PR Use the template plugin and avoid the need for local sudo #28 (which I already merged in our fork's master branch)
  ps: You can see molecule tests run via Travis (activated on our repo): https://travis-ci.com/github/scigility/cloudera-playbook/builds/175154546
