Example result:. In the case of classic CLI we are relying on the built-in rollback feature. Therefore it is required that the rollback location is properly configured.
For example:. After every successful configuration request one need to make sure, that a new checkpoint is created. If the configuration was changed through this Ansible plugin, the checkpoint is automatically created. Skip to content.

So, what does this module do? If you follow the link provided above, you will reach the official documentation, which is good. In the previous article I have explained how to install it. See the previous article to get details how to build the lab. In order to make our job more efficient, I have created a couple of Ansible playbookswhich configures routers properly. So, just launch the playbook or copy-paste the configuration to the CLI. Here is the playbook itself:. Remove leading dot in each line.
The XML structure is similar to one, we have already explored. The crucial point here is that we use variables, which are fetched from per-node date read in the second action of the playbook. This playbooks is equal to the following code for SR1 keeping in mind that per-node data is inserted :. I will show only relevant part:.
As you can see, the number of interfaces has increased up to 5 from 4 and each router has its own IP addresses, which we have defined in per-node data. For sure, during operation of the routers we not only create configuration, but we also remove it sometimes. Now we continue with another important vendor. By the end of the day, after execution of the policy we should get the following interfaces created:. From this output we see that playbook was played successful, so we can check the status of the interfaces again:.
At Cisco website I have found one articlewhich shows how to delete something using another approach. Therefore, I have highlighted with bold necessary modifications into initial XML. The first one is caused by the environment. Nothing has helped. So, the main outcome here is that now we have much more components to take care about therefore troubleshooting become more complex. It has very reach capabilities for debugging, which I have extensively used during writing the article.
If you have some problems with the execution, just launch playbook in the following way:. You will see all the detailed information, how the data is fetched from the variables, how the data is structured, what is send in the message to the module and what is received.Ansible delivers simple IT automation that ends repetitive tasks and frees up DevOps teams for more strategic work.

February 8, by Sean Cavanaugh. The upcoming Ansible 2. In typical Ansible fashion, development of networking enhancements is done in the open with the help of the community. You can follow along by watching the networking GitHub project boardas well as the roadmap for Ansible 2.
Continued Enablement for Declarative Intent. Prior to Ansible 2. A playbook executed the python module locally, and then connected to a networking platform to perform tasks. This was sufficient, but different than how most non-networking Ansible modules functioned.
In general, most Ansible modules are executed on the remote host, compared to being executed locally on the Ansible control node. Although many networking platforms can execute Python code, the vast majority require the CLI or an API as the only means for interacting with the device. In an effort to help streamline the passing of credentials, network modules support an additional parameter called a provider, first introduced in Ansible 2.
A network automation playbook would run locally, use an Ansible inventory just like a normal playbook but then use the provider on a task-by-task basis to authenticate and connect to each networking platform. This differs from a Linux focused playbook that would initially login to devices using credentials in the inventory itself or passed through the command line.
The provider method is functional for networking but is a different paradigm compared to connection methods on Linux hosts. With Ansible 2. This allows playbooks to look, feel and operate just like they do on Linux hosts. Let's show what this means for your playbooks:. Ansible 2. There are additional advantages for executing playbooks at the command line as well.
All of the command line options for non-networking platforms can now be used on networking platform playbooks as well. For example, the user, password, connection method and enable parameters can be passed on the command line instead of just the playbook. NETCONF also becomes a top-level connection, resulting in connection: netconf to be called at the top level rather than having to be specified as a provider argument.
Although not all networking platforms support the NETCONF connection method more to comewe believe this represents the future for network automation. Connecting to, parsing and passing structured data instead of terminal CLI commands is more reliable, and Ansible is excited to be able to add this feature request. Therefore, it is now possible to specify the connection method for each managed network device inside the inventory file, which adds flexibility and compatibility for multiple networking platforms.
This variable informs Ansible which network platform each host corresponds to. This can be set as a variable or even within the inventory itself as shown above. In the playbooks shown above, network automation veterans have noticed another change. Previously when using connection: localif gathering facts was not disabled it would gather facts about the local system. With the new connection methods, fact gathering no longer needs to be disabled.
With the Ansible 2.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. February 24, by Andrius Benokraitis. Since then, there have been two additional Ansible releases and more than modules added, with 24 networking vendor platforms enabled. With the fantastic efforts from the community and our networking partners, Ansible has been able to add more and more features for networking use cases.
In the forthcoming Ansible 2. Since Ansible 2. As this list grows we expect to have even more platforms and modules in Ansible 2. The development of these plugins further demonstrates the value and investment Ansible and the community have made into networking infrastructure enablement.
As we approach the Ansible 2. In order to better understand why including persistent connections support is a substantial benefit in Ansible 2. A connection plugin defines how Ansible communicates with inventory hosts. A list of all currently available connection plugins can be found on the Ansible GitHub repository. Playbooks with multiple tasks require SSH connections to be established and destroyed each time, resulting in extremely high overhead for completion. Adding persistent connection support allows one SSH connection to stay active across multiple Ansible tasks, therefore reducing the total time for completion.
In order for Playbooks to take advantage of the persistent connections framework, new connection plugins must to be created, specifically for certain use cases. Although these first plugins are primarily for networking infrastructure use cases, other plugins utilizing persistent connections are in plan for future Ansible releases.
Ansible 2. The new plugins are now natively integrated into Ansible core and allow Playbook designers to enjoy a more seamless approach to automating network devices. By moving to a plugin approach for configuring connectivity to network devices, tasks and modules can take advantage of new plugins while utilizing the local connection plugin. This means that device connectivity is now handled by Ansible across compute and network devices in a uniform fashion. In order to leverage the new connection plugins, new and existing modules must be modified.
When new and existing modules are modified, the local connection method stays unchanged, and therefore all Playbooks themselves. We are working closely with both our technology partners and the Ansible community to update as many of the current network modules are possible. Under the covers, there are two connection methods that can be used, including the following:.
In Ansible 2. It is designed to work with traditional network devices that require connectivity to a device CLI in order to configure resources. The netconf connection plugin provides module developers with the opportunity to develop modules that interface with remote devices using the NETCONF standard.

In the nutshell, Ansible is an automation tool for configuring system, deploying software, and orchestrating services. Unlike Puppet and Chef which is an agent-based architecture, Ansible does not require daemon running or agent pre-installed on the target nodes to perform configuration tasks. Ansible could be specified to run either on local server or on remote node.
The different between local and remote connection mode in Ansible is basically where the script so-called Ansible module is being run. For the remote mode, Ansible automatically attempts to establish SSH connection to the remote node. Once established, it transfers the script and runs it on the remote node. The script responds to the server in JSON formatted text. As for the local mode, Ansible run the module script on the local server.
The script has to establish a connection to the remote node itself. With different variants for local and remote modes mentioned earlier, before implementing Ansible modules, one needs to be aware of their limitation. Skip to content.

The user account executing the module must have permissions to change the relevant portions of the configuration on each target device. The configuration data file, junos-config.
If the control machine fails to establish a NETCONF session with a target device during playbook execution, it skips over the other tasks in the play for that device. The load: "merge" module argument loads the new configuration data into the candidate configuration using a load merge operation.
Creating the Configuration Data File. Creating the Ansible Playbook. Optional Create a task to print the response, which includes the configuration changes in diff format. On the Ansible control machine, review the completed playbook.
If the playbook does not display the intended code, repeat the instructions in this example to correct the playbook. Issue the ansible-playbook command on the control machine, and provide the playbook path and any desired options.
Review the Ansible playbook output to see whether the configuration task succeeded or failed. You can also log in to the device running Junos OS and view the configuration, commit history, and log files to verify the configuration and commit, for example:. Troubleshooting Timeout Errors. Troubleshooting Configuration Lock Errors.
Troubleshooting Configuration Change Errors. The playbook generates a TimeoutExpiredError error message and fails to update the device configuration. Large configuration changes might exceed this value causing the operation to time out before the configuration can be uploaded and committed. The playbook generates a LockError error message indicating that the configuration cannot be locked.
For example:. The LockError message string usually indicates the root cause of the issue.
If another user has an exclusive lock on the configuration or has modified the configuration, wait until the lock is released or the changes are committed, and execute the playbook again. If the cause of the issue is that the user does not have permissions to configure the device, either execute the playbook with a user who has the necessary permissions, or if appropriate, configure the device running Junos OS to give the current user the necessary permissions to make the changes.
The playbook generates a ConfigLoadError error message indicating that the configuration cannot be modified, because permission is denied. This error message is generated when the user executing the Ansible module has permission to alter the configuration but does not have permission to alter the requested section of the configuration. Either execute the playbook with a user who has the necessary permissions, or if appropriate, configure the device running Junos OS to give the current user the necessary permissions to make the changes.Common return values are documented herethe following are the fields unique to this module:.
If you notice any issues in this documentation, you can edit this document to improve it. Ansible 2. This module can be used to easily enable the Netconf API.
Netconf provides a programmatic interface for working with configuration and state resources as defined in RFC This argument specifies the port the netconf service should listen on for SSH connections. The default port as defined in RFC is Starting with Ansible 2. Specifies the DNS host name or address for connecting to the remote device over the specified transport. The value of host is used as the destination address for the transport.
Specifies the password to use to authenticate the connection to the remote device.
This value is used to authenticate the SSH session. Specifies the port to use when building the connection to the remote device.
Ansible and Cisco
Specifies the SSH key to use to authenticate the connection to the remote device. This value is the path to the key used to authenticate the SSH session. Specifies the timeout in seconds for communicating with the network device for either connecting or sending commands. If the timeout is exceeded before the operation is completed, the module will error. Configures the username to use to authenticate the connection to the remote device. If the state argument is set to present the netconf service will be configured.
If the state argument is set to absent the netconf service will be removed from the configuration. This module also works with local connections for legacy playbooks. This practice avoids potential resource conflicts. Default: Deprecated Starting with Ansible 2. A dict object containing connection details.
