Installing Ansible Ansible - Ansible Documentation

This section describes release cycles, rules, and maintenance schedules for both Ansible community projects: the Ansible community package and ansible-core. The two projects have different versioning systems, maintenance structures, contents, and workflows.Ansible community packageansible-coreUses new versioning (2.10, then 3.0.0)Continues “classic Ansible” versioning (2.11, then 2.12)Follows semantic versioning rulesDoes not use semantic versioningMaintains only one version at a timeMaintains latest version plus two older versionsIncludes language, runtime, and selected CollectionsIncludes language, runtime, and builtin pluginsDeveloped and maintained in Collection repositoriesDeveloped and maintained in ansible/ansible repositoryMany community users install the Ansible community package. The Ansible community package offers the functionality that existed in Ansible 2.9, with more than 85 Collections containing thousands of modules and plugins. The ansible-core option is primarily for developers and users who want to install only the collections they need.Release cycle overviewAnsible community package release cycleAnsible community changelogsansible-core release cycleansible-core control node Python supportansible-core target node Python supportansible-core target node PowerShell and Windows supportansible-core support matrixPreparing for a new releaseFeature freezesRelease candidatesDevelopment and maintenance workflowsAnsible community package workflowansible-core workflowGenerating changelogsDeprecation cyclesAnsible community package deprecation cycleansible-core deprecation cycleRelease cycle overviewThe two community releases are related - the release cycle follows this pattern:Release of a new ansible-core major version, for example, ansible-core 2.11New release of ansible-core and two prior versions are now maintained (in this case, ansible-base 2.10, Ansible 2.9)Work on new features for ansible-core continues in the devel branchCollection freeze (no new Collections or new versions of existing Collections) on the Ansible community packageRelease candidate for Ansible community package, testing, additional release candidates as necessaryRelease of a new Ansible community package major version based on the new ansible-core, for example, Ansible 4.0.0 based on ansible-core 2.11Newest release of the Ansible community package is the only version now maintainedWork on new features continues in CollectionsIndividual Collections can make multiple minor and major releasesMinor releases of three maintained ansible-core versions every four weeks (2.11.1)Minor releases of the single maintained Ansible community package version every four weeks (4.1.0)Feature freeze on ansible-coreRelease candidate for ansible-core, testing, additional release candidates as necessaryRelease of the next ansible-core major version, cycle begins againansible-core release cycleansible-core is

Due to these qualities and fast adoption of Ansible, we created a tutorial full of examples so you can have an even more seamless first experience in working with Ansible.In this Ansible basics tutorial, we described ansible and talked a bit about its history. We mentioned the strong points of Ansible and the advantages that ansible can bring to automation and orchestration of infrastructures of different sizes. We defined the essential ansible used terms and defined the structure of Ansible playbooks. Thorough examples accompanied all information with detailed explanations.

Culture¶Many network engineers prefer to use the CLI for all things networking, like troubleshooting, ad-hoc operational configuration changes, and full-blown greenfield provisioning tasks.To harvest the full benefit of Ansible and Ansible AVD, you must learn to think differently and change your working methods.Ansible should be your first choice when changing your network configuration, whether small or big. The CLI should only be used for troubleshooting, i.e., viewing the state of your network or those urgent scenarios at 2 AM where you need to change something particular on just one or two devices, followed by proper configuration cleanup later.How does Ansible work?¶Before we can tell Ansible to do anything, Ansible needs to know about your network’s devices (or hosts).This is defined in the Ansible inventory. Per the official Ansible documentation, the inventory is a file type in either INI or YAML format, but other inventory sources can be used. In Ansible AVD, we use YAML format by default; hence the file is called inventory.yml, located in the Ansible AVD project folder (in this case, single-dc-l3ls):Please note that the example above is taken from the Ansible AVD Examples repository, specifically the Single-DC-L3LS.The exact name of the inventory file isn’t important but is provided to Ansible in the ansible.cfg file for the project or as ansible-playbook -i ./inventory.yml when later running Ansible.Inventories¶An example of a snippet of the inventory.yml file is shown below (a subset of an actual file for clarity).As stated earlier, this file is in YAML format.The hostnames specified in the inventory must exist either in DNS or in the hosts file on your Ansible host to allow successful name lookup and be able to reach the switches directly. To test this, you must be able to successfully ping the host, for example, ping dc1-spine1 from your Ansible host. Alternatively, if there is no DNS available, or if devices need to be reached using a fully qualified domain name (FQDN), define ansible_host to be an IP address or FQDN for each device - see dc1-spine1/2 below for an example:---all: children: FABRIC: children: DC1: children: DC1_SPINES: hosts: dc1-spine1: ansible_host: 172.16.1.11 dc1-spine2: ansible_host:.

Mentioned before. Each role can be run independently by specifying the tag in the ansible-playbook command line with the –t parameter.---- hosts: all user: root port: 22 gather_facts: True roles: - { role: selinux, tags: selinux } - { role: httpd, tags: httpd } - { role: resolver, tags: resolver }Running the p4.yml playbook on two hosts and interpreting the output. The same command can be run with the –check parameter for a dry-run. In case you want to use password authentication, use -k parameter.Explanation:Ansible-playbook command that runs p4.ymlPlaybook skipsSELinux role because it is already enabled.Ansible found that httpd package is already installed, so it returns ok.Resolver was set, and role resolver got status changed.Ansible Commands Cheat SheetInstall EPEL repo on Centos/RHEL systems[root@ansible-server ~]# sudo yum install epel-releaseInstall ansible package on Centos/RHEL systems[root@ansible-server ~]# sudo yum install -y ansiblePerform an update to the packages on Debian/Ubuntu systems$ sudo apt updateInstall the software-properties-common package on Debian/Ubuntu systems$ sudo apt install software-properties-commonInstall ansible personal package archive on Debian/Ubuntu systems$ sudo apt-add-repository ppa:ansible/ansibleInstall ansible on Debian/Ubuntu systems$ sudo apt update$ sudo apt install ansibleIssue a ping command on all servers defined in the inventory file named hosts [root@ansible-server test_ansible]# ansible -i hosts all -m pingIssue a ping command only on host2[root@ansible-server test_ansible]# ansible -i hosts all -m ping --limit host2Copy the file “testfile” on all hosts in the inventory file[root@ansible-server test_ansible]# ansible -i hosts all -m copy -a "src=/root/test_ansible/testfile dest=/tmp/testfile"Install ncdu package on all hosts[root@ansible-server test_ansible]# ansible -i hosts all -m yum -a

Simple example of idempotency would be a pair of on/off buttons for a machine - no matter how many times you push ‘on,’ the device will only turn on once.Unlike other tools, Ansible doesn’t use a proprietary communications mechanism or agent on the device being managed. Instead, it leverages industry-standard protocols for device access, including SSH and REST APIs. This also means that Ansible doesn’t require the setup of any unique infrastructure - it’s entirely possible to automate tasks using nothing but your laptop or desktop computer (but a central deployment server is recommended).Ansible describes tasks in a structured language called YAML. Unlike other languages such asJSON and XML, YAML was designed to be human-readable. YAML will be covered further later on in the sectionHow does Ansible work.By now, you can probably appreciate that we can use Ansible to automate many things. This document will focus only on using Ansible to provision Arista EOS devices with or without Arista CloudVision.What are the requirements to run Ansible?¶Ansible can run on almost anything, but in production scenarios, Ansible is typically deployed on a virtual Linux server, running on the customer’s preferred hypervisor. This Ansible server then communicates directly with the Arista network devices via eAPI or Arista CloudVision Portal, which in turn communicates with the Arista network devices. Controlling what Ansible does is typically done using an SSH terminal session to the Ansible server from the Operator’s computer.What is the arista.avd collection?¶Arista.avd is an Ansible collection for Arista Validated Designs. It’s maintained byArista and accepts third-party contributions on GitHub at aristanetworks/avd.While Ansible is the core automation engine, AVD is an Ansible Collection described above. It provides roles, modules, and pluginsthat allow the user to generate and deploy best-practice configurations to Arista based networks of various design types: Data Center, Campus and Wide Area Networks.The illustration above shows the arista.avd collection as a box with a red background on the right-hand side.When designing an EVPN/VXLAN L3LS fabric, you don’t need to spend hours reading through the Arista Design and Deployment Guides. Instead, the AVD collection will implement those rules and guidelines.AVD is an

Developed and released on a flexible release cycle. We can extend this cycle to properly implement and test larger changes before a new release is made available. See ansible-core Roadmaps for upcoming release details.ansible-core has a graduated maintenance structure that extends to three major releases.For more information, read about the Development and maintenance workflows orsee the chart in ansible-core control node Python support for the degrees to which current releases are maintained.NoteOlder, unmaintained versions of ansible-core can contain unfixed security vulnerabilities (CVEs). If you are using a release of ansible-core that is no longer maintained, we strongly encourage you to upgrade as soon as possible to benefit from the latest features and security fixes. ansible-core maintenance continues for 3 releases. Thus the latest release receives security and general bug fixes when it is first released, security and critical bug fixes when the next ansible-core version is released, and only security fixes once the follow on to that version is released.You can refer to the Ansible Core Porting Guides for tips on updating your playbooks to run on newer versions of ansible-core.You can install ansible-core with pip. See Installing Ansible for details.ansible-core control node Python supportStarting with ansible-core version 2.12, each release includes control node support for the three most recently released Python versions.ansible-core target node Python supportStarting with ansible-core version 2.16, each release includes target node support for:The 6 most recently released Python versions.The 7 most recently released Python versions every 6th ansible-core release (2.16, 2.22, etc.)Support for Python 2.7 is included in ansible-core version 2.16 and earlier.ansible-core target node PowerShell and Windows supportansible-core on Windows supports the baseline version of PowerShell that each Windows version ships with. For example, Windows Server 2016 shipped with PowerShell 5.1 so Ansible will support PowerShell 5.1 for the life of Windows Server 2016 support. Support for each Windows version is determined by the Windows lifecycle policy and when each version reaches the extended end date. For example Windows Server 2012 and 2012 R2 extended end date was for October 10th 2023 while Windows Server 2016 is January 12th 2027. Windows support does not. Table of Contents.

We will go through the steps of installation in different Linux distributions, the most popular ones, in the next small tutorial.Install Ansible on Centos/RedHat systemsStep 1) Install EPEL repo[root@ansible-server ~]# sudo yum install epel-releaseStep 2) Install ansible package[root@ansible-server ~]# sudo yum install -y ansibleInstall ansible on Ubuntu/Debian systemsStep 1) Perform an update to the packages$ sudo apt updateStep 2) Install the software-properties-common package$ sudo apt install software-properties-commonStep 3) Install ansible personal package archive$ sudo apt-add-repository ppa:ansible/ansibleStep 4) Install ansible$ sudo apt update$ sudo apt install ansibleAnsible ad-hoc commandsOne of the simplest ways Ansible can be used is by using ad-hoc commands. These can be used when you want to issue some commands on a server or a bunch of servers. Ad-hoc commands are not stored for future uses but represent a fast way to interact with the desired servers.For this Ansible tutorial, a simple two servers hosts file will be configured, containing host1 and host2.You can make sure that the hosts are accessible from the ansible server by issuing a ping command on all hosts.[root@ansible-server test_ansible]# ansible -i hosts all -m pinghost1 | SUCCESS => { "changed": false, "ping": "pong"}host2 | SUCCESS => { "changed": false, "ping": "pong"}Explanation:Status of the command, in this case, SUCCESSHost on which the command ranThe command issued via the -m parameter, in this case,

This example used -l option to limit the playbook to only executing on the rtr1 node.[user@ansible ~]$ ansible-playbook playbook.yml -l rtr1PLAY [configure cisco routers] *************************************************TASK [configure hostname] ******************************************************changed: [rtr1]TASK [configure DNS] ***********************************************************changed: [rtr1]PLAY RECAP *********************************************************************rtr1 : ok=2 changed=2 unreachable=0 failed=0This playbook configured the hostname and DNS servers. You can verify that configuration on the Cisco IOS XE rtr1 router:rtr1#sh run | i namehostname rtr1ip name-server 8.8.8.8 8.8.4.4Convert the playbook into a roleThe next step is to convert this playbook into a reusable role. You can create the directory structure manually, or you can use ansible-galaxy init to create the standard framework for a role.[user@ansible ~]$ ansible-galaxy init system_demo[user@ansible ~]$ cd system_demo/[user@ansible system_demo]$ tree.├── defaults│ └── main.yml├── files├── handlers│ └── main.yml├── meta│ └── main.yml├── README.md├── tasks│ └── main.yml├── templates├── tests│ ├── inventory│ └── test.yml└── vars └── main.ymlThis first demonstration uses only the tasks and vars directories. The directory structure would look as follows:[user@ansible system_demo]$ tree.├── tasks│ └── main.yml└── vars └── main.ymlNext, move the content of the vars and tasks sections from the original Ansible Playbook into the role. First, move the two tasks into the tasks/main.yml file:[user@ansible system_demo]$ cat tasks/main.yml---- name: configure hostname cisco.ios.ios_config: lines: hostname {{ inventory_hostname }}- name: configure DNS cisco.ios.ios_config: lines: ip name-server {{dns}}Next, move the variables into the vars/main.yml file:[user@ansible system_demo]$ cat vars/main.yml---dns: "8.8.8.8 8.8.4.4"Finally, modify the original Ansible Playbook to remove the tasks and vars sections and add the keyword roles with the name of the role, in this case system_demo. You’ll have this playbook:---- name: configure cisco routers hosts: routers connection: ansible.netcommon.network_cli gather_facts: false. Table of Contents.

PingWith the -i parameter, you can point to the hosts file.You can issue the same command only on a specific host if needed.[root@ansible-server test_ansible]# ansible -i hosts all -m ping --limit host2host2 | SUCCESS => { "changed": false, "ping": "pong"}Explanation:Limit parameter can be used to issue commands only on specific hosts in the host’s fileName of the host as defined in the inventory fileIf you need to copy a file to multiple destinations rapidly, you can use the copy module in ansible which uses SCP. So the command and its output look like below:[root@ansible-server test_ansible]# ansible -i hosts all -m copy -a "src=/root/test_ansible/testfile dest=/tmp/testfile"host1 | SUCCESS => { "changed": true, "checksum": "da39a3ee5e6b4b0d3255bfef95601890afd80709", "dest": "/tmp/testfile", "gid": 0, "group": "root", "md5sum": "d41d8cd98f00b204e9800998ecf8427e", "mode": "0644", "owner": "root", "size": 0, "src": "/root/.ansible/tmp/ansible-tmp-1562216392.43-256741011164877/source", "state": "file", "uid": 0}host2 | SUCCESS => { "changed": true, "checksum": "da39a3ee5e6b4b0d3255bfef95601890afd80709", "dest": "/tmp/testfile", "gid": 0, "group": "root", "md5sum": "d41d8cd98f00b204e9800998ecf8427e", "mode": "0644", "owner": "root", "size": 0, "src": "/root/.ansible/tmp/ansible-tmp-1562216392.6-280302911361278/source", "state": "file", "uid": 0}Explanation:Copy module definedModule arguments, in this case, are source absolute path and destination absolute path.Ansible command output reflecting the success of the copy command and other details like the sha1 or md5 checksums for file integrity check and metadata like owner, size, or permissions.It is effortless to have a package installed on a bunch of servers. Ansible has several modules that interact with used installers, like yum, apt, dnf, etc.In the next example, you will find out how to install a package via the yum module on two Centos hosts.[root@ansible-server test_ansible]#
