In the present day, we’re supplying you with two extra causes to make use of Ansible to handle your Oracle Cloud sources:

Ansible and Ansible Modules

Ansible is an Infrastructure-as-code automation device that gives a straightforward strategy to provision and configure your infrastructure sources. Ansible modules are a discrete unit of code made out there by suppliers corresponding to Oracle. You possibly can execute these modules from the command line or in a playbook job on the goal node to make the specified provider-specific infrastructure adjustments.   

Ought to I Use Ansible? Or Ought to I exploit Terraform? 

The reply is… Sure. On a severe be aware, let’s first evaluate these two instruments.

  Ansible Terraform
Sort Primarily configuration administration however can do orchestration too Orchestration
Infrastructure Mutable Immutable
Language Procedural Declarative
State Administration No Sure



Terraform is a robust infrastructure orchestration device (and arguably the most well-liked one at this time) however as Hashicorp puts it: “Terraform will not be a configuration administration device.” Then again, Ansible is primarily as a configuration administration device with some orchestration capabilities.  


In a mutable infrastructure, you replace and modify your current infrastructure to make the specified change. Within the in style Pets vs Cattle analogy, these infrastructure elements are your pets. You reside with them, title them ,and watch them develop up. 

In an immutable infrastructure paradigm, you by no means modify the present infrastructure. To make a change, you tear them down and create a brand new set of infrastructure. They’re your cattle. In case you do not like the best way they’re, you merely exchange them with the opposite ones.  


Terraform follows a declarative language whereas Ansible modules observe procedural language. To elucidate the distinction, let’s assume you desire a complete of 10 compute situations. Within the case of Terraform, you’ll declare a remaining depend of compute (10) and it’ll deal with the result. In case you initially had 5 situations, Terraform  creates a further 5 situations. However when you had 15 situations, it destroys 5. 

With Ansible, you outline the precise variety of situations to be created. So if you wish to have 10 situations, you first question the present occasion depend after which ask for the specified variety of new situations.   

State Administration

Terraform shops the state of your atmosphere in a state file whereas Ansible doesn’t have the equal idea. As a substitute, you utilize the inventory feature to get the real-time standing of your atmosphere.    

The instruments have the next traits in frequent:

  • They’re each open supply.

  • They’ve sturdy group participation and recognition.

  • Neither follows the primary-replica structure, decreasing the ache associated to managing the administration device.

Coming again to the unique query of which device to pick out, the reply relies upon! We ask our clients to evaluate their necessities and choose the appropriate device primarily based on their want and skill-set. Broadly, we’ve noticed two kinds of consumer segments.

The primary kind of buyer makes use of each the instruments together for his or her respective strengths. They provision the infrastructure utilizing Terraform after which leverage the Ansible Inventory function to handle the configuration.

The second kind of buyer prefers to make use of solely Ansible for a number of of the next causes:

  • They need to use a single device for configuration and orchestration to reduce complexity.
  • Ansible is Python-based.
  • They do not need to handle the state file.

On the subject of choosing the appropriate device, you may additionally think about, Resource Manager, our managed Terraform-as-a-service. Along with the state-management profit, it supplies further advantages corresponding to native integration with different Oracle cloud service, drift detection, and resource discovery.

What’s New with Oracle Ansible Modules?

Glad you requested! We’re asserting two helpful consumer advantages. 

Ansible Assist for All Oracle Cloud Sources

We enabled Ansible assist for Oracle Cloud two years in the past. Since then Ansible utilization amongst Oracle clients has grown steadily and considerably. This progress mirrors the broader market pattern the place Ansible has develop into essentially the most preferred configuration management device. Till now, we supplied assist for under a particular set of Oracle Cloud sources, however you requested for extra, and we heard you!

Now you can handle all of your Oracle Cloud sources utilizing Ansible. Assist is on the market for all of the Oracle Cloud companies and options launched by June 2020. We’re persevering with so as to add assist for extra companies and options as they’re launched.

Ansible Assortment is Usually Out there

Final 12 months, Ansible released Collections as a part of the Ansible 2.9 launch. Ansible Assortment is a straightforward strategy to provision and handle sources in Oracle Cloud. In the present day, we’re asserting the provision of Oracle Cloud Infrastructure Ansible Collection. With this launch, you’ll be able to set up and handle Assortment far more simply. The brand new assortment additionally tackle different challenges corresponding to problem in code sharing for a lot of plugins and plugin/function title collisions. 

The Oracle Cloud Ansible Assortment replaces the legacy Oracle Cloud Ansible modules.

Deprecation of Legacy Modules

With the discharge of the brand new assortment, the legacy Oracle Cloud Ansible modules can be found solely within the upkeep mode. We’re not including assist for brand new options. Additionally, we’re fixing solely important bugs. Past mid-2021, the legacy modules deprecate. In case you transition from the legacy modules to the brand new assortment modules, count on just a few breaking changes. Seek advice from the Migration Guide as you intend emigrate.

Set up

You possibly can set up the Oracle cloud assortment from Ansible Galaxy utilizing the next command:

$ ansible-galaxy assortment set up oracle.oci

Assortment is supported in Ansible 2.9+. To replace the modules to the newest model, use the set up –force flag.
