QUESTION
I'm trying to use my Ansible playbook to call upon a site YAML reference to create a filename that increment for multiple switches. What am I doing wrong? I believe the playbook is pulling from the host YAML?
Format: --.txt
e.g.: with two switches:
- swi-lon-101.txt
- swi-lon-202.txt
host_vars/host.yaml
...ANSWER
Answered 2022-Mar-31 at 18:39So, you do need a loop in order to set this fact, otherwise, you are trying to access a installation_floor on a list, which cannot be.
You will also face an issue with the id of your items in switch_stacks, as 01 is an int and will end up displayed as 1, simply. So you either need to declare those as string, or to pad them with a format filter.
So, you end up with this task:

Answered 2022-Mar-28 at 15:22If you want to obey the lint line length rule, you need to split your url on several lines.

The best solution here is to use a double quoted flow scalar where you can escape new lines so that they are not converted to white spaces, e.g.:

I made a playbook with two task
The first task is for getting all the directories in the selected directory.
The second task is for deleting the directories. But, I only want to delete a directory if the list length is longer than two.
ANSWER
Answered 2022-Mar-15 at 14:40This won't be possible, once a module is executed, the result is saved in the variable and won't dynamically change with the state of the node.
What you should do instead is to limit the list you are looping on with a slice notation to exclude the three last items of the said list: files[:-3].
So, your task deleting files would look like this:
QUESTION
I'm looking for a way of specifying that a module argument can't be used if another argument has a certain value.
You can specify required_if to require an argument if another argument has a specific value but I need the opposite.
Something that's conceptually similar to mutually_exclusive and might be called forbidden_if.
I'm developing a module that creates a login for an SQL server. It can either be a SQL login that's specific to the server or a Windows log in that uses the domain controller. For an SQL login you must specify a password for but you can't for Windows as this is set by the domain controller. Logins have an identifier (SID) that may be specified by the user for SQL logins but can't be for Window.
Although it's a Powershell module for a Windows host I'll use Python examples because that's what the documentation is in.
This is the spec for a module that creates an SQL login

QUESTION
I am having a hard time getting to know how to create Ansible roles that are following the best practices according to documentation. The following use-case which I am looking at is e.g. enabling Filebeat on host. Filebeat can be configured by placing a module definition in /etc/filebeat/modules.d folder.
It works fine when I am adding modules. Idempotence is working, everytime, on each run of the role (playbook), a given set of modules is enabled.
But what I should do when I decide that a given module is not longer needed? I remove it from role, rerun a playbook, so that all other modules are enabled. But: the previous run enabled a module that I am not installing directly with role after changes. So my server state is still altered in a way that is different than the role is imposing itself.
My question is: should I take care of removing modules before I apply them so I always start from, let's say, fresh state?

QUESTION
I'm trying to use Ansible to deploy a small k3s cluster with just two server nodes at the moment. Deploying the first server node, which I refer to as "master" is easy to set up with Ansible. However, setting up the second server node, which I refer to as "node" is giving me a challenge because I need to pull the value of the node-token from the master and use it to call the k3s install command on the "node" vm.
I'm using Ansible roles, and this is what my playbook looks like:

I am deploying multiple R versions on multiple virtual desktops. I've built 3.6.3 and 4.1.2 R from source on Ubuntu 18.04.3 LTS. None of them finds the system-wide Rprofile.site file in /etc/R or the system certificates in /usr/share/ca-certificates. However R (3.4.4) installed with APT has no such problems. I used Ansible, but for the sake of this question I reproduced the deployment for one host with a shell script.

Answered 2022-Jan-14 at 17:25Finally I found the solution:
Since both system has the arch and OS. I cross copied the R compiled installations between them. The R which was compiled on the problematic system, but was run on the correct one gave the warnings below after the calling of the install.packages("renv", repos="https://cran.wu.ac.at/")

I have an Ansible 2.9.27 and I am trying to add upstream remote for git repositories which I previously cloned with Ansible. Let's assume that already cloned repositories are located in /home/user/Documents/github/ directory and I want to add upstream remote for them (git remote add upstream for each repo).
The task looks like this:
...ANSWER
Answered 2021-Dec-29 at 18:44Since what you want to achieve is not (yet...) taken in charge by the git module, this is a very legitimate use of command.
In such cases, it is possible to silence the specific rule in ansible lint for that specific task.
To go a bit further, your changed_when: false clause looks a bit like a quick and dirty fix to silence the no-changed-when rule and can be enhanced in conjunction with a failed_when clause to detect cases where the remote already exists.
Here is how I would write that task to be idempotent, documented and passing all needed lint rules:
QUESTION
We've had a working Ansible AWX instance running on v5.0.0 for over a year, and suddenly all jobs stop working -- no output is rendered. They will start "running" but hang indefinitely without printing out any logging.
The AWX instance is running in a docker compose container setup as defined here: https://github.com/ansible/awx/blob/5.0.0/INSTALL.md#docker-compose
ObservationsStandard troubleshooting such as restarting of containers, host OS, etc. hasn't helped. No configuration changes in either environment.
Upon debugging an actual playbook command, we observe that the command to run a playbook from the UI is like the below:
ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && rm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_data && ansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml
That's broken down into three commands in sequence:
ssh-agent sh -c ssh-add /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_datarm -f /tmp/awx_11021_0fmwm5uz/artifacts/11021/ssh_key_dataansible-playbook -vvvvv -u ubuntu --become --ask-vault-pass -i /tmp/awx_11021_0fmwm5uz/tmppo7rcdqn -e @/tmp/awx_11021_0fmwm5uz/env/extravars playbook.yml
You can see in part 3, the -vvvvv is the debugging argument -- however, the hang is happening on command #1. Which has nothing to do with ansible or AWX specifically, but it's not going to get us much debugging info.
I tried doing an strace to see what is going on, but for reasons given below, it is pretty difficult to follow what it is actually hanging on. I can provide this output if it might help.
So one natural question with command #1 -- what is 'ssh_key_data'?
Well it's what we set up to be the Machine credential in AWX (an SSH key) -- it hasn't changed in a while and it works just fine when used in a direct SSH command. It's also apparently being set up by AWX as a file pipe:
prw------- 1 root root 0 Dec 10 08:29 ssh_key_data
Which starts to explain why it could be potentially hanging (if nothing is being read in from the other side of the pipe).
Running a normal ansible-playbook from command line (and supplying the SSH key in a more normal way) works just fine, so we can still deploy, but only via CLI right now -- it's just AWX that is broken.
ConclusionsSo the question then becomes "why now"? And "how to debug"? I have checked the health of awx_postgres, and verified that indeed the Machine credential is present in an expected format (in the main_credential table). I have also verified that can use ssh-agent on the awx_task container without the use of that pipe keyfile. So it really seems to be this piped file that is the problem -- but I haven't been able to glean from any logs where the other side of the pipe (sender) is supposed to be or why they aren't sending the data.
ANSWER
Answered 2021-Dec-13 at 04:21Had the same issue starting this Friday in the same timeframe as you. Turned out that Crowdstrike (falcon sensor) Agent was the culprit. I'm guessing they pushed a definition update that is breaking or blocking fifo pipes. When we stopped the CS agent, AWX started working correctly again, with no issues. See if you are running a similar security product.

Install ansible
You can use ansible like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
