Ansible tower workflow examples

Workflows allow you to configure a sequence of disparate job templates or workflow templates that may or may not share inventory, playbooks, or permissions. A workflow accomplishes the task of tracking the full set of jobs that were part of the release process as a single unit.

Job or workflow templates are linked together using a graph-like structure called nodes. These nodes can be jobs, project syncs, or inventory syncs. A template can be part of different workflows or used multiple times in the same workflow. A copy of the graph structure is saved to a workflow job when you launch the workflow. Workflows utilize the same behavior hierarchy of variable precedence as Job Templates with the exception of three additional p1615 nissan. The three additional variables include:.

Workflows included in a workflow will follow the same variable precedence - they will only inherit variables if they are specifically prompted for, or defined as part of a survey. In this example, there are two playbooks that can be combined in a workflow to exercise artifact passing:. In the workflow scheme, canceling a job cancels the branch, while canceling the workflow job cancels the entire workflow. To edit and delete a workflow job template, you must have the admin role.

To create a workflow job template, you must be an organization admin or a system admin.

You must have execute access to a job template to add it to a workflow job template. Other tasks such as the ability to make a duplicate copy and re-launch a workflow can also be performed, depending on what kinds of permissions are granted to a particular user. Generally, you should have permissions to all the resources used in a workflow like job templates before relaunching or making a copy.

Container Platform Support 1.Ansible delivers simple IT automation that ends repetitive tasks and frees up DevOps teams for more strategic work. Leverage powerful automation across entire IT teams no matter where you are in your automation journey. January 9, by Bianca Henderson. Suppose you have a workflow set up in Red Hat Ansible Tower with several steps and needed another user to view and approve some or all of the nodes in the workflow. Or maybe a job is running inside of a workflow but it should be viewed and approved within a specific time limit, or else get canceled automatically?

Perhaps it would be useful to be able to see how a job failed before something like a cleanup task gets set off? It is now possible to insert a step in between any job template or workflow within that workflow in order to achieve these objectives. The Workflow Approval Node feature has been available in Ansible Tower since the release of version 3. In order to visually compare the additional functionality, examine the before and after examples of a workflow job template below:.

You can easily create approval nodes just like any other workflow node, via the Workflow Visualizer in the Ansible Tower UI:. From here, you will see Approval as a node type that you can add, with a specific name required as well as a description and timeout optional :. When an approval node needs attention, a bell icon on the top right corner of the screen newly added for this feature! Simply click on that icon to view details for those approval nodes:.

Another way to be alerted to when an approval node needs review is for notifications to be set on the Approval level. When a notification is set in this manner, it will alert the recipient when any approval node inside of that workflow :. And below is how default Slack notifications look like for approval nodes:. Most notification types will include a URL to view the job in need of attention, for ease of review.

For more information on how to enable and disable notifications in Ansible Tower, see the documentation page on this topic. Note: Customized notifications work for approvals, too! See the Ansible Tower documentation about this customized template feature to learn more. Another added detail that increases the usefulness of this feature is the Timeout option.

Since RBAC is an important part of Ansible Tower, we wanted to make sure that there would be very specific permissions related to approval nodes. Below is a chart that shows details at-a-glance:. This table is taken from documentation, the most up to date version can be found here. On the top level, the System Administrator role has permissions for everything approval-related. The Auditor may view the approval and see information about it in the activity stream, but they do not automatically receive approval permissions to actually give the OK for the workflow to proceed.

In relation to this feature, there is a new type of user permission that was introduced: the Approve role. They do not gain the ability to create approval nodes, unless they already had permission to do so e. In the Ansible Tower UI, select any user you would like to assign the Approve role to, and click the Permissions button:. In the permissions window, click the Add button green plus sign in order to add a new permission level, then select Workflow or Organization.

If selecting Workflowyou will need to select the specific workflow you want them to have approval access to. The screenshot below is an example of what a user will see while doing this:. In order to add the Approve role via Organization, click the Permissions button and the Add button as before. From there, click on the Organization tab, select the appropriate organization, and then select Approve from the drop-down of available roles:.

For a user to only have Approve permissions for specific workflows, it is best to apply the permission at a workflow level.

This blog post covered what exactly approval nodes are, how to implement them into your workflows, details about related features such as notification alerts and timeouts, as well as approval-specific RBAC. This information should enable you to incorporate more control and oversight into your Ansible Tower workflows; for further reading on this topic, see the Ansible Tower documentation.Workflows allow you to configure a sequence of disparate job templates or workflow templates that may or may not share inventory, playbooks, or permissions.

Identify Next Steps. In this example we have a single workflow which handles CI. Back when I used to use Ansible to manage AWS infrastructure I would use this workflow some steps have been removed for applying roles to an EC2 instance: Create instance role.

It is the same in Ansible Tower. When you use the integrations UI, you can only configure the visible properties. Specifically, the objects in the table below. If you choose to copy a workflow template, it does not copy any associated schedule, notifications, or permissions. As an example take our current code for creating a LXC container and configuring some basic settings. Ansible Tower 3. After installing the plugin you can configure Ansible Tower servers in the Jenkins Global Configuration under the section Ansible Tower by clicking the add button.

Chef vs. Workflows were introduced as a major new feature in Ansible Tower 3. Centralize your Ansible infrastructure from a modern UI, featuring role-based access control, job scheduling, and graphical inventory management. In the Ansible web UI, navigate to the Inventories section using the left navigation bar.

My goal was to be able to have Github PRs Pull Requests to trigger a workflow template to perform some automated testing using an Ansible Tower workflow. It assumes that you have no Ansible server setup, but do have a working vRealize Automation instance. Open the web UI and click on the Templates link on the left menu. Check Situation Alerts. A simple workflow we saw users creating was a linear pipeline; similar to the workflow below.

Ansible Tower Workflow Questions I'm working on using Ansible to apply a new disk image to a set of servers and provision the OS after it's booted for the first time.

It allows Tower commands to be easily run from the Unix command line.Workflow Templates link multiple Job Templates together. Furthermore, the links can be conditional. For example:. This actually allows you to have different teams, make their own Job Templates or even their own Projects and still link them together all to the work into as one coherent Workflow. You can also use that post as a refresher for how to create Job Templates and Surveys. The first step in this example is to create three Job Templates.

These Job Templates will be the building blocks for a Workflow Template. These Job Template examples are straight forward. Use this information when creating the Job Templates. Default variables can be added to workflows to override any variables set in the playbooks or to allow setting variables. Once this is done the actual Workflow Template can now be created. The node gets annotated with the name of the job.

We are also going to add some extra variables to this Workflow so that its settings are consistent and so that you can see how this can be done. Refer back to the earlier linked post to remember how to create a survey. You need the following to be defined. Note how the workflow run is shown in the job view. In contrast to a normal Job Template job execution, this time there is no playbook output on the right. Instead you will see a visual representation of the different workflow steps.

A system build team wants to require approval before launching a workflow that provisions machines. The idea behind this project is that a workflow can be split at any edge that requires an approval to traverse. This means there will be multiple workflows that actually function as a larger one. Each approval gate creates an approval request that is represented by a job template that only the approval team specific to the approval gate that created it can execute.

The approval request job template will launch the next workflow and set all current workflow artifacts as extra variables. Any extra variables set on the approval gate job template itself will also be passed on to the next workflow.

It must be configured to authenticate with the target Ansible Tower server and the associated user account must have system administrator type so that the necessary resources can be created in Tower.

All configuration of Tower has been automated. The very first thing that needs to be done is configuring your tower-cli to use a system administrator user. It is recommended to create a new user specifically for this project. The automation will actually create credentials in Tower keep in mind these are encrypted so that job templates can leverage them. This will configure Tower with all necessary resources to enable creating an approval gate job template.

To create an approval gate job template perform the following:. After performing these steps when a user launches the workflow the gate job template will create an approval request job template that is configured to launch the next job.

The next job is only launched if the approver actually approves the request. Skip to content. This repository has been archived by the owner.
