Common Issues and Resolutions

Issue 1: Job Failed with "Authentication failure"

Symptoms:

TASK [Gathering Facts] ***
fatal: [host]: UNREACHABLE! => {"changed": false, "msg": "Failed to connect to the host via ssh: Permission denied (publickey,password)."}

Diagnosis Steps:

1. Check credential configuration in AWX:

   • AWX UI → Credentials → [credential-name]
   • Verify credential type (Machine, Source Control, etc.)
   • Check which organization owns it

2. Verify credential is attached to job template:

   • AWX UI → Templates → [template-name] → Credentials tab
   • Should see SSH credential listed

3. Check credential content:

   • SSH Private Key populated?
   • Username correct?
   • Privilege escalation configured?

Resolution:

# Update credential via CaC
# File: data/awx_credentials.yml
awx_credential_list:
  - name: "epic-ssh-credential-dev"
    description: "SSH key for dev environment"
    organization: "Epic Platform"
    credential_type: "Machine"
    inputs:
      username: "ansible"
      ssh_key_data: "{{ lookup('file', '~/.ssh/epic_dev_rsa') }}"
      privilege_escalation_method: "sudo"
      become_username: "root"

# Apply update
ansible-playbook pb_create_awx_credential.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @data/awx_credentials.yml

Issue 2: Project Sync Failed

Symptoms:

ERROR! Project update failed
fatal: Could not read from remote repository

Diagnosis Steps:

1. Check project settings:

   • AWX UI → Projects → [project-name]
   • SCM URL correct?
   • SCM Branch specified?
   • SCM Credential attached?

2. Test GitHub access from AWX:

   # From AWX execution environment
   git ls-remote https://github.com/optum-tech-compute/ohemr-ansible-playbooks
   

3. Verify SCM credential:

   • AWX UI → Credentials → [scm-credential]
   • Personal Access Token valid?
   • Token has repo read permissions?

Resolution A: Update SCM Credential

# data/awx_credentials.yml
awx_credential_list:
  - name: "github-pat-epic"
    description: "GitHub PAT for Epic repos"
    organization: "Epic Platform"
    credential_type: "Source Control"
    inputs:
      username: "epic-platform-sre"
      password: "{{ lookup('env', 'GITHUB_PAT') }}"  # From vault

# Apply
ansible-playbook pb_create_awx_credential.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @data/awx_credentials.yml

Resolution B: Update Project Configuration

# data/awx_projects.yml
awx_project_list:
  - name: "ohemr-ansible-playbooks"
    description: "Epic on Azure playbooks"
    organization: "Epic Platform"
    scm_type: "git"
    scm_url: "https://github.com/optum-tech-compute/ohemr-ansible-playbooks"
    scm_branch: "main"  # Or specific branch
    scm_credential: "github-pat-epic"
    scm_clean: true  # Force clean checkout
    scm_delete_on_update: true  # Remove local mods
    scm_update_on_launch: true

# Apply
ansible-playbook pb_create_awx_project.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @data/awx_projects.yml

Issue 3: Job Failed - "No hosts matched"

Symptoms:

ERROR! Couldn't resolve host: server-123
skipping: no hosts matched

Diagnosis Steps:

1. Check inventory:

   • AWX UI → Inventories → [inventory-name] → Hosts
   • Does host exist?
   • Is hostname correct?

2. Check job template limit:

   • AWX UI → Templates → [template-name]
   • Limit field - does it filter out your host?

3. Verify inventory sync:

   • If dynamic inventory, check last sync time
   • Run inventory update if stale

Resolution A: Fix Inventory

# data/awx_hosts.yml
awx_host_list:
  - name: "server-123.azure.optum.com"  # FQDN
    inventory: "epic-dev-inventory"
    enabled: true
    variables:
      ansible_host: "10.20.30.40"  # IP if DNS issue
      env: "dev"

# Apply
ansible-playbook pb_create_awx_host.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @data/awx_hosts.yml

Resolution B: Launch with Corrected Limit

# test_launch.yml
awx_job_launch_list:
  - name: "my-job-template"
    limit: "server-123.azure.optum.com"  # Use FQDN
    wait: true

# Launch
ansible-playbook pb_create_awx_job_launch.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @test_launch.yml

Issue 4: Job Failed - "Module not found"

Symptoms:

ERROR! couldn't resolve module/action 'community.windows.win_firewall'

Diagnosis Steps:

1. Check execution environment:

   • AWX UI → Templates → [template-name]
   • Which EE is configured?
   • Does EE contain required collection?

2. Verify collection requirements:

   • In playbooks repo: collections/requirements.yml
   • Is collection listed?

3. Check if collection installed in EE:

   # From EE
   ansible-galaxy collection list | grep community.windows
   

Resolution A: Update Execution Environment

Build new EE with required collections:

# execution-environment.yml
version: 3
dependencies:
  galaxy: requirements.yml
  python: requirements.txt

# requirements.yml
collections:
  - name: community.windows
    version: '>=1.12.0'
  - name: ansible.windows
    version: '>=1.13.0'

# Build EE
ansible-builder build -t epic-ee:v2.0

# Push to registry
podman tag epic-ee:v2.0 registry.optum.com/epic-ee:v2.0
podman push registry.optum.com/epic-ee:v2.0

Resolution B: Update Job Template EE

# data/awx_job_templates.yml
awx_job_template_list:
  - name: "windows-firewall-config"
    job_type: "run"
    inventory: "windows-servers"
    project: "ohemr-ansible-playbooks"
    playbook: "pb_configure_firewall.yml"
    execution_environment: "Epic EE v2.0"  # Updated
    credentials:
      - "windows-credential"

# Apply
ansible-playbook pb_create_awx_job_template.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @data/awx_job_templates.yml

Issue 5: Job Failed - Task timeout

Symptoms:

TASK [Long running operation] ***
fatal: [host]: FAILED! => {"msg": "Timeout (12s) waiting for privilege escalation prompt"}

Diagnosis Steps:

1. Check task timeout settings
2. Review privilege escalation configuration
3. Check if sudo requires password
4. Network latency issues?

Resolution:

# Increase timeouts in job template
awx_job_template_list:
  - name: "long-running-job"
    job_type: "run"
    timeout: 3600  # 1 hour
    extra_vars:
      ansible_timeout: 300  # 5 min per task
      ansible_sudo_timeout: 60

# Or in playbook
- name: Long running task
  ansible.builtin.command: /opt/app/install.sh
  async: 3600  # Run async
  poll: 10  # Check every 10s

Issue 6: Inventory Sync Failed

Symptoms:

ERROR! Inventory source update failed
Failed to parse dynamic inventory

Diagnosis Steps:

1. Check inventory source:

   • AWX UI → Inventories → [inventory] → Sources
   • Source type (Azure, custom script, etc.)
   • Credential attached?

2. Test inventory script manually:

   # Run inventory script
   python inventory_script.py --list
   

3. Check Azure credential (if Azure source):

   • Service Principal still valid?
   • Has required permissions?

Resolution A: Fix Azure Inventory Source

# data/awx_inventory_sources.yml
awx_inventory_source_list:
  - name: "azure-vms-dev"
    inventory: "epic-dev-inventory"
    source: "azure_rm"
    credential: "azure-sp-dev"
    update_on_launch: true
    overwrite: true
    source_vars:
      resource_groups:
        - "rg-epic-dev-eastus2"
      conditional_groups:
        citrix_vda: "'vda' in name"
        app_servers: "'app' in name"

# Apply
ansible-playbook pb_create_awx_inventory_source.yml \
  -e controller_host=awx-dev.optum.com \
  -e controller_oauthtoken=$AWX_DEV_TOKEN \
  -e @data/awx_inventory_sources.yml

Resolution B: Fix Custom Inventory Script

# inventory_azure_custom.py
#!/usr/bin/env python3
import json
import sys
from azure.identity import DefaultAzureCredential
from azure.mgmt.compute import ComputeManagementClient

def get_inventory():
    credential = DefaultAzureCredential()
    compute_client = ComputeManagementClient(credential, subscription_id)

    inventory = {
        '_meta': {'hostvars': {}},
        'all': {'hosts': [], 'children': []}
    }

    for vm in compute_client.virtual_machines.list_all():
        hostname = vm.name
        inventory['all']['hosts'].append(hostname)
        inventory['_meta']['hostvars'][hostname] = {
            'ansible_host': get_vm_ip(vm),
            'vm_size': vm.hardware_profile.vm_size
        }

    return inventory

if __name__ == '__main__':
    print(json.dumps(get_inventory(), indent=2))

Issue 7: Variable Override Not Working

Symptoms:

• Job uses wrong variable value
• Extra vars not applied
• Survey values ignored

Diagnosis Steps:

1. Check variable precedence:

   • extra_vars (highest)
   • job_template vars
   • inventory vars
   • role defaults (lowest)

2. Verify extra_vars syntax:

   # Correct
   extra_vars:
     my_var: "value"
   
   # Wrong - double nesting
   extra_vars:
     extra_vars:
       my_var: "value"
   

3. Check survey configuration:

   • AWX UI → Templates → [template] → Survey
   • Variable name matches playbook?

Resolution:

# Correct job launch with extra_vars
awx_job_launch_list:
  - name: 'my-template'
    extra_vars:
      # Flat structure
      environment: 'dev'
      app_version: '2.1.0'
      enable_monitoring: true
    wait: true

# If from command line
# awx job_template launch --name="my-template" \
#   --extra_vars='{"environment": "dev", "app_version": "2.1.0"}'

Diagnostic Commands

Check Job Status

# List recent jobs
awx jobs list --limit=10 --status=failed

# Get job details
awx jobs get <job-id>

# Get job stdout
awx jobs stdout <job-id>

Check Project Status

# List projects
awx projects list

# Get project details
awx projects get --name="ohemr-ansible-playbooks"

# Trigger project update
awx projects update --name="ohemr-ansible-playbooks" --wait

Check Credentials

# List credentials
awx credentials list --organization="Epic Platform"

# Get credential details (sensitive fields hidden)
awx credentials get --name="epic-ssh-credential-dev"

Check Inventory

# List inventories
awx inventory list

# List hosts in inventory
awx inventory_host list --inventory="epic-dev-inventory"

# Get host details
awx inventory_host get --name="server-123" --inventory="epic-dev-inventory"

Preventive Measures

1. Enable Job Notifications

# data/awx_notification_templates.yml
awx_notification_template_list:
  - name: 'teams-epic-sre'
    notification_type: 'msteams'
    organization: 'Epic Platform'
    notification_configuration:
      url: 'https://outlook.office.com/webhook/...'

# Attach to job template
awx_job_template_list:
  - name: 'critical-job'
    # ...
    notification_templates_error:
      - 'teams-epic-sre'
    notification_templates_success:
      - 'teams-epic-sre'

2. Set Up Healthchecks

# Schedule periodic test jobs
awx_schedule_list:
  - name: 'nightly-connectivity-check'
    rrule: 'DTSTART:20250101T020000Z RRULE:FREQ=DAILY'
    unified_job_template: 'test-connectivity'
    enabled: true

3. Implement Logging

# In playbooks - log to external system
- name: Log job start
  uri:
    url: 'https://logging.optum.com/api/awx-jobs'
    method: POST
    body_format: json
    body:
      job_id: '{{ tower_job_id }}'
      template: '{{ tower_job_template_name }}'
      started: '{{ ansible_date_time.iso8601 }}'

4. Document Runbooks

Create runbooks for common operations and issues in your team wiki or SharePoint.

Escalation Path

If issue cannot be resolved:

1. Check AWX Server Health

   • CPU, memory, disk usage
   • Database connectivity
   • Redis/message queue health

2. Review AWX Server Logs

   • /var/log/tower/ on AWX server
   • Kubernetes logs if AWX on K8s

3. Engage Platform Team

   • Provide job ID and error details
   • Include diagnostic output
   • Note any recent platform changes

4. Open Support Ticket

   • AWX version
   • Ansible version
   • Complete error messages
   • Steps to reproduce
