I also have a variable with a fixed name (ENV) which holds this prefix. I dont want to list all the variables in the playbook, but instead dynamically grab them from the environment, remove the prefix, and feed them to the environment key in the ansible task. Variable names should be letters, numbers, and underscores. Variables should always start with a letter. fooport is a great variable. foo5 is fine too.- hosts: webservers tasks: - name: create directory for ansible custom facts. Ansible variables help to determine how the tasks execute on different systems based on the values assigned to these variables. Ansible variable names should be letters, numbers, underscores and they should always start with a letter. And if we were to apply the role the following variables would be set for us to use throughout the Ansible play.And if we reach a task in which requires a notifier to fire off a restart of the webserver service: - name: debian | installing php5. In version 0.7 Ansible can store the output of a given command in a variable which I use later on in templates, say. The register keyword names the variable. --- - hosts: 127.0.0.1 connection: local vars: - person: Jane Jolie - filename: v1.j2 varsfiles: - vars.yml tasks: - name: Quien soy? action But note that variable names have some restrictions in Ansibletasks: - name: copy template template: srctemplate.j2 dest"/tmp/abcapp.
conf". When this task is run against a set of systems, the all get a file called abcapp.conf containing the individual host name of the given system. When running my playbook, on tasks that I have tried to name with variables, the variable name is there rather than the value.Ansible cant tell the variable has only one value, since the variable is "inventory scope" as such, it cant plug it in, because the task header (that preceeds the next 500 In your case I assume you want to send a notification via slack as soon as the task runs, to do this you could add your slack notification task below your "upload to kerbenetes config" task or you could use a task include with a parameter. Example: Main.yml: -. Name: Upload kubernetes config template: src Naming convention for user settable variables.
Naming convention for role variables (i.e. user setting default value).Limit setfact to variables that depend on the outcome of task execution. So heres the deal: youll hear the words "facts" and "variables" in Ansible basically interchangeably.pretasks: - name: Convert entered Symfony environment to lowercase. setfact Registering stdout as ansible variables. - debug: msg" hello.stdout " - debug: msg" hello.stderr ". Including task with variables- name: so question 39041208 hosts: target | default("all") tasks: - name: Find the last Hello world in foo.txt, and get the value of N shell: awk /Hello world You have already seen how the variable ansiblesshuser can be set and change how ansible connects to remote hosts.Here is one example: to install multiple packages you can do this in a loop: tasks: - name: install debugging tools. I cannot get this seemingly simple example to work in Ansible 1.8.3. The variable interpolation does not kick in the task name.Given that the variable is defined in the vars section I expected the task name to print the value of the variable. How do I access a variable name programmatically?In Ansible 1.8 and later, if you have a task that you dont want to show the results or command given to it when using -v (verbose) mode, the following task or playbook attribute can be useful This is easy to do in Ansible, with the when clause, which contains a Jinja2 expression (see Variables). Its actually pretty simple: tasks: - name: "shutdown Debian flavored systems" command: /sbin/shutdown -t now when: ansibleosfamily "Debian". First, you need to register an arbitrary variable to identify your task. - name: Check if webroot exists stat: path: /var/www/publichtml register: webroot.Ansible offers the changedwhen or failedwhen parameters to achieve just that. It also offers a few more fine-grained options (e.g This is just as true for processes spawned by Ansible as it is for processes spawned by your shell. If you want to set an ansible variable, consider using the register keyword to get the value: - hosts: localhost gatherfacts: false tasks: - name: get wget version. How to group tasks(folder structure) in an ansible role? Ansible 2.3: ways to encrypt sensitive variable values defined in host inventory file for each host.pretasks: - name: disable the server in haproxy haproxy: statedisabled backendmyapplb host inventoryhostname socket Ansible set variable task?

How can I get the task name as it is printed on stdout with the variable expanded? ansible. Your answer. Im just starting to learn ansible. Ive set up a test repository here. Im trying to include a task, and pass it a message as a variable that should be printed by the task. My playbook (site.yml) is structured like this: - name: default playbook tasks: - include: tasks/timestamp.yml, themsgstarting tasks . Also, how to interpolate variables or dynamic variable names. Why dont you ship in X format? I dont see my question here.In Ansible 1.8 and later, if you have a task that you dont want to show the results or command given to it when using -v (verbose) mode, the following task or playbook attribute Edit an encrypted file (uses vim by default, can be overriden by the environment variable EDITOR) ansible-vault edit secrets.yml .hosts: tagenvproduction:tagtypedb tasks: - name: This task will be run on all servers with tags envproduction and typedb tasks: - name: "shut down CentOS 6 systems" command: /sbin/shutdown -t now when: - ansibledistribution "CentOS"-a -b -c. Note: If Ansible detects that the current loop is using a variable which has already been dened, it will raise an error to fail the task. In the following example, Im storing the current time in a variable at the beginning of my play. - name: lookups in variables vsAnsible evaluates lookups for a variable every time that variable is used in the task at the time the task is run. That means the lookup value could be different in different tasks. In Ansible, we use Variables as a way to deal with things that differ between one system and the next.To use a variable in a task is really easy, we just enclose the variable name in some double handlebars . tasks: - name: Install Apache Web Server. yum: namehttpd statelatest.Variables One of the ways to make playbooks more generic is to use Ansible variables. Variables can be defined in multiple locations. I have a play below that contains a task with a name that has a variable in it. hosts: localhost connection: local vars: a variable: test tasks: - name: this is a task to echo avariable shell: echo a variable . - name: print out operating system hosts: all gatherfacts: True tasks: - debug: var ansibledistribution.These facts are available as keys of a special variable named ansible local. Variables fill in the contents of template files, can be used for the source of files, and to choose whether or not to perform a task (to name some reasons).ansible provides a tool called ansible-vault for encrypting secret variables. while other tools are available, the vault is usefully integrated. 2) Ansible playbook extra-vars for conditional task. 2 register a variable when param1 install - name: validate task if param1 value is install command: echo TechieRoop register: installTrue when: param1 is defined and param1 install . But there is a rule for naming variables. Variable names should be letters, numbers, and underscores. Variables should always start with a letter.Task includes pull from other files. Tasks in Ansible go with pretty much the English meaning of it. Bootstrap a new role named "nginx" ansible-galaxy init nginx. The directory name roles is a convention Ansible uses to find roles when running a playbook.Ansible facts all start with anisble and are globally available for use any place variables can be used: Variable files, Tasks, and Templates.

Inventory file defaults to /etc/ ansible/hosts.alice: name: Alice Appleworth telephone: 123-456-7890. bob: name: Bob Bananarama telephone: 987-654-3210. tasks: - name: Print phone records. It is recommended to name all the Ansible tasks in a very descriptive manner in your provisioning script.You also can specify group variables or host variables that will help to control how Ansible interacts with remote hosts and they will be available later in playbooks. Whenever you can, let Ansible complain loudly when a variable is undefined, instead of e.g. skipping a task conditionally.Consistently name your variables. Just like code, Ansible plays should be grep-able. Note that Ansible provides a default group that will apply variables to all machines in the inventory that group is represented by all.The tasks/main.yml file would look like this with the changed variable name Problem: To create a variable in Ansible playbook using current date and time. Solution: Use setfact and lookup plugins in Ansible. --- - hosts: localhost vars: tasks: - name: new variable with current date time. The first mapping has the keys name and file. Its good practice to give each task a name key, even though its not required. The tasks name doesThe log file location is stored in an Ansible variable. One way to set the different variable values for different environments is by both a) creating an Tagged: Ansible. Viewing 2 posts - 1 through 2 (of 2 total).I have a play below that contains a task with a name that has a variable in it. hosts: localhost connection: local vars: a variable: test tasks: - name: this is a task to echo avariable shell: echo a variable . Since Ansible evaluates groups alphabetically, the variable associated with whichever group name happens to be last in dictionary ordering will win . . The equivalent playbook using includevars, which operates as a task, would look like: --- - name: variable precedence test hosts: localhost tasks ISSUE TYPE. Bug Report. Component name. ??? ansible version.It is not possible to define task vars from a dict variable. Steps to reproduce. - hosts: localhost tasks: - setfact: dict: key: value - debug Ansible can work with metadata from various sources and manage their context in the form of variables.If a configuration file gets changed notify a service restart task that it needs to run. Example Handler Task in a Play. tasks: - name: httpd package is present yum: name: httpd state You can use lookup. filever: "1.5" debfile: " lookup(ini, remotetmp sectiondefaults file ansible.cfg /debfile filever .deb" EDIT In case you dont know the path to the configuration file, you can set that to a fact by running the following tasks. - name: look for ansible.cfg, see http - name: get the operators name pause: prompt: "Please enter your name" register: opname. There is one last variable type, the extra variables, or extra-varsData for role variables, play variables, and task variables can also come from external sources. Ansible provides a mechanism to access and - name: Task5.
You may need to execute only the last 3 tasks from this playbook.Ansible Assign output of a shell command to a ansible variable for a later use. The following code will execute the shell command hostname -s and then assign its output and return code to Variables from groupvars are not substituted into task names (like variables passed in other ways)This same thing is happening in my ansible script. Im trying to make the names more specific and informative but getting the variable name printed out instead You are at: Home » Ansible task variable output not displaying.name: "test" hosts: webservers. tasks: - name: Echo myenvvar shell: "echo MYENV VARIABLE" environment: MYENVVARIABLE: whatevervalue Starting from v2.0 Ansible supports variable substitution in task/handler names: https://github.com/ansible/ansible/issues/10347, so these examples will work as expected: - name: upgrade software on inventoryhostname - name: current host is ansiblehostname. You can pass variables in command line. ansible-playbook release.yml --extra-vars "version1.23.45 other variablefoo".--- - hosts: all remoteuser: root vars: favcolor: blue varsfiles: - /secretvars.yml tasks: - name: this is just a placeholder.
