CloudForms Set Role

Disblamer

I provide no guarantee that this script will work or if it is safe to run on your appliance. Use at your own risk. This not an official Red Hat supported script.

Description

This repo contains an Ansible module and command line script that will update a ManageIQ/CloudForms appliance with requested roles.

Reqiurements:

How To Use The Ansible Module

The evm_roles directory contains 3 example playbooks that call the predefined Ansible roles to disable, enable, and list EVM roles. The enable and disable EVM roles playbooks expect an extra vars variable called role which should equal a valid EVM role.

  • The script will install the configure_server_settings.rb for you in vmdb/tools if its not already there.

disable_role.yml enable_role.yml list_roles.yml

You can test the playbook using something like this directly on your CloudForms/ManageIQ appliance:

# cd evm_roles
# ansible-playbook -vvv enable_role.yml --extra-vars=role=rhn_mirror
# ansible-playbook -vvv disable_role.yml --extra-vars=role=rhn_mirror
# ansible-playbook -vvv list_roles.yml

Here is an example to get things going for the command line script:

# vmdb
# cd tools
# wget https://raw.githubusercontent.com/ManageIQ/manageiq/master/tools/configure_server_settings.rb
# wget https://raw.githubusercontent.com/rut31337/setrole/master/setrole.sh
# chmod +x setrole.sh configure_server_settings.rb

How To Run Command Line Script

Here is the usage for setrole.sh:

Usage: ./setrole.sh -r|--role <role to enable/disable>
          -l|--list <comma separated list of ALL roles> (danger, no checking done)
          -s|--serverid <server id>, default=1
          -d|--dryrun
If using --list you must provide all roles that will be enabled, any missing roles in this list will be DISABLED.

List Option

Important
 Using this option incorrectly can be impede you ability to reach your appliance (such as disabling the UI role), please read this in full.

  • The --list option allows you to specify a comma separated list of all the roles you want your appliance to have enabled. If you do not provide the role in the list it will be DISABLED. Be very careful doing this as you may disable roles you didn’t expect to disable. This is really designed to be run as part of an automation. No checking is provided to see if the roles you are requesting are valid roles!! Use this at your own risk.

    # ./setrole.sh --list automate,database_operations,embedded_ansible,ems_inventory,ems_operations,event,git_owner,reporting,scheduler,smartstate,user_interface,web_services,websocket

Role Option

  • The --role option allows you to specify a single role at a time. If the role is already enabled it is disabled and vice versa. The role being requested is checked to make sure its a valid MIQ server role.

    # ./setrole.sh --role embedded_ansible

Server ID

If you need to provide a server ID other than 1 you can specify it with --serverid <x>

Testing and Debugging

If you would like to run this script safely you can use the -d or --dryrun option so that it does not make any changes. This works for both the list and role options.

# ./setrole.sh -r notifier -d
Role notifier is currently disabled, we will enable it.
{:dry_run=>true, :serverid=>1, :path=>"server/role", :value=>"automate,database_operations,embedded_ansible,ems_inventory,ems_operations,event,git_owner,reporting,scheduler,smartstate,user_interface,web_services,websocket,ems_metrics_coordinator,notifier", :help=>false, :serverid_given=>true, :path_given=>true, :value_given=>true, :dry_run_given=>true}
Setting [server/role], old value: [automate,database_operations,embedded_ansible,ems_inventory,ems_operations,event,git_owner,reporting,scheduler,smartstate,user_interface,web_services,websocket,ems_metrics_coordinator], new value: [automate,database_operations,embedded_ansible,ems_inventory,ems_operations,event,git_owner,reporting,scheduler,smartstate,user_interface,web_services,websocket,ems_metrics_coordinator,notifier]
Dry run, no updates have been made
