Please see the Foreman manual for appropriate instructions:
Set up the repo as explained in the link above, then run
# yum install ruby193-rubygem-foreman-tasks
Add the following to bundler.d/Gemfile.local.rb in your Foreman installation directory (/usr/share/foreman by default)
$ gem 'foreman-tasks'
Then run bundle install and foreman-rake db:migrate from the same directory
To verify that the installation was successful, go to Foreman, top bar Administer > About and check 'foreman-tasks' shows up in the System Status menu under the Plugins tab. You should also see a 'Tasks' button under the Monitor menu in the top bar.
In the UI, go to /foreman_tasks/tasks. This should give a list of
tasks that were run in the system. It's possible to filter that using
scoped search. Possible searches:
# search all tasks by user
owner.login = admin
# search all tasks on architecture with id 9
resource_type = Architecture and resource_id = 9
Clicking on the action, it should provide more details.
Via API:
curl -k -u admin:changeme\

- Audit: tasks history for resources and users
- Possibility to generate CLI examples
- Locking: connection between task and resource: allows listing tasks for a resource but also allows preventing to run two conflicting tasks on one resource.
- Dynflow integration allowing async processing, workflows definitions etc.
This engine is agnostic on background processing tool and can be used with anything that allows supports some kind of execution hooks.
On the other side, since we started this as part of Katello integration with Dynflow, the dynflow adapters are already there.
Also, since dynflow has no additional dependencies in terms of another database (tested mainly on Postgres), this gem ships the Dynflow setting so that Dynflow can be used directly.
It's turned off by default, but you can turn that on with putting this code somewhere in Rails initialization process. In case of an engine, it would be:
initializer "your_engine.require_dynflow", :before => "foreman_tasks.initialize_dynflow" do |app|
ForemanTasks.dynflow.require!
endAdditionally, there are also examples of using Dynflow for async tasks
and auditing included in this repository. To enable them you just need
to set FOREMAN_TASKS_MONKEYS env variable to true
FOREMAN_TASKS_MONKEYS=true bundle exec rails sThe example for async tasks handling is the puppet facts import. Next time puppet imports the facts to Foreman, the task should appear in the tasks list.
The example for auditing features is the architecture model. On every modification, there is a corresponding Dynflow action triggered. This leads to it appearing in the tasks list as well, even there was no async processing involved, but still using the same interface to show the task.
The Dynflow console is accessible on /foreman_tasks/dynflow path.
In development mode, the Dynflow executor is part of the web server
process. However, in production, it's more than suitable to have the
web server process separated from the async executor. Therefore,
Dynflow is set to use external process in production mode by default
(can be changed with ForemanTasks.dynflow.config.remote = false).
The executor process needs to be executed before the web server. You can run it by:
RAILS_ENV=production bundle exec rake foreman_tasks:dynflow:executor
Also, there is a possibility to run the executor in daemonized mode
using the dynflow-executor. It expects to be executed from Foreman
rails root directory. See -h for more details and options
The issues are tracked here
TBD - dig into the code for now (happy hacking:)
