Use Hashicorp Vault with Ansible - plugin setup - ansible

I want to use Hashicorp Vault with Ansible to retrieve username/password which I will use in Ansible playbook.
Vault is setup - I created a secret. What are the steps to integrate both? the documentation around plugins isn't that great. I tried the file lookup from ansible and this works but how to use 3rd party plugins? Can somebody help me with the steps to follow?
Install the plugin, pip install ansible-modules-hashivault
What is the difference with https://github.com/jhaals/ansible-vault
2.a The environment variables (VAULT ADDR & VAULT TOKEN) I put where?
Change ansible.cfg to point to vault.py which is located in "plugin" folder of my Ansible Project
To test basic integration, can I use the following playbook?
https://pypi.python.org/pypi/ansible-modules-hashivault
- hosts: localhost
-tasks:
- hashivault_status:
register: 'vault_status'
Tried this but I get:

Since you put so many eggs into the post, that I have no clue what the question is really about, here's something to get you going with the native lookup plugin and jhaals/ansible-vault.
you can create lookup_plugins in the current directory and save vault.py inside;
the VAULT_ADDR and VAULT_TOKEN environment variables are as you see them in the script;
The Bash script below (it uses screen and jq, you might need to install them) runs Vault in dev mode, sets the secret, and runs Ansible playbook which queries the secret with two lookup plugins:
#!/bin/bash
set -euo pipefail
export VAULT_ADDR=http://127.0.0.1:8200
if [[ ! $(pgrep -f "vault server -dev") ]]; then
echo \"vault server -dev\" not running, starting...
screen -S vault -d -m vault server -dev
printf "sleeping for 3 seconds\n"
sleep 3
else
echo \"vault server -dev\" already running, leaving as is...
fi
vault write secret/hello value=world excited=yes
export VAULT_TOKEN=$(vault token-create -format=json | jq -r .auth.client_token)
ansible-playbook playbook.yml --extra-vars="vault_token=${VAULT_TOKEN}"
and playbook.yml:
---
- hosts: localhost
connection: local
tasks:
- name: Retrieve secret/hello using native hashi_vault plugin
debug: msg="{{ lookup('hashi_vault', 'secret=secret/hello token={{ vault_token }} url=http://127.0.0.1:8200') }}"
- name: Retrieve secret/hello using jhaals vault lookup
debug: msg="{{ lookup('vault', 'secret/hello') }}"
In the end you should get:
TASK [Retrieve secret/hello using native hashi_vault plugin] *******************
ok: [localhost] => {
"msg": "world"
}
TASK [Retrieve secret/hello using jhaals vault lookup] *************************
ok: [localhost] => {
"msg": {
"excited": "yes",
"value": "world"
}
}
The word world was fetched from Vault.

Ansible script to create new kafka connector

I have been creating different connectors in our confluent installation by using the curl command to PUT a configuration to a url. The set-up is normally done by adding the configuration and curl call in a shell script. We either write separate shell scripts for each environment or pass the server names - broker and connect - as parameters.
I want to write an ansible script to define new connectors which will basically be same script that can be run in all environments and will only depend on the hosts file in each environment. This will help in eliminating user error / typos in server names when running it in different environments.
My current plan is to just convert the shell script and use ansible shell or command module to call 'curl' and pass the parameters. But I am not sure, if that is the correct way, even if it may get the job done.
Does anyone have any suggestion to do it correctly / properly.
Thank you
UPDATE
Based on #Zeitounator's recommendation, I tried to use the uri module. But keep on getting error

How do I identify which file it is complaining about?

UPDATE 2
I ran the script in verbose mode and I get below stack trace. If I comment out the cert and key parts, then I get connection refused, so it seems the cert and key are required. I tried to search for the cause of the error without success. The certificate and key files do exist at the location. What else do I need to check?

Lookup secrets from AWS secret manager | Ansible

Using Terraform code I have created Other type of secrets in AWS Secrets Manager.
I need to use these AWS secrets in Ansible code. I found this below link but I am unable to proceed it.
https://docs.ansible.com/ansible/2.8/plugins/lookup/aws_secret.html
I have below Ansible code:-
database.yml
- name: Airflow | DB | Create MySQL DB
mysql_db:
login_user: "{{ mysql_user }}"
# login_password: "{{ mysql_root_password }}"
login_password: "{{ lookup('ca_dev', 'mysql_root_password') }}"
# config_file: /etc/my.cnf
# login_unix_socket: /var/lib/mysql/mysql.sock
# encrypted: yes
name: "airflow"
state: "present"
How can I incorporate AWS secret Manager in my ansible code?

ansible-doc -t lookup -l output
The error {"msg": "lookup plugin (ca_dev) not found"} suggests your issue is the misuse of the lookup command.
The following line:
login_password: "{{ lookup('ca_dev', 'mysql_root_password') }}"
Should look something like
login_password: "{{ lookup('aws_secret', 'mysql_root_password') }}"
ca_dev is not a valid lookup type, whereas aws_secret is.
You can see a list of supported lookup plugins for Ansible 2.8 in the Lookup Plugins section of the official documentation.
If you are using a custom lookup plugin, or backporting a plugin from a future version of ansible to an older version, you must make sure that it is in a directory visible to ansible.
You can either place the custom file in the default location ansible looks in ~/.ansible/plugins/lookup:/usr/share/ansible/plugins/lookup or configure your ansible.cfg to look in a different place using the following lookup_plugins ini key under the defaults section.
DEFAULT_LOOKUP_PLUGIN_PATH

How can I quote the vaulted variables correctly? Because I don't know in advance, if the vaulted variables will contain single or double quotes.
Your problem description, despite being well written, unfortunately wrongly attributes the problem to Ansible Vault.
In fact, the problem you reported, comes simply from trying to execute the task which effectively becomes:
- command: echo abc"def
Ansible Vault plays no role in causing this problem -- if you defined the variable directly with foo: abc\"def you'd get the same error message.
The solution is simply to quote the string in the echo command:
- command: echo '{{ foo }}'
Other than that you can use quote filter, but for Vault-protected variable you need to first set a static fact:
- set_fact:
bar: "{{ foo }}"
- command: echo {{ bar|quote }}
Finally, the simplest solution to the underlying problem is: do not use special characters in passwords. Increase the length instead.

serial: "100%"
hosts: all
sudo: yes
roles:
- role: "ansible-pull"
server_type: "sensu"

Where the ansible-pull role depends on the ansible role in meta/main.yml.
Am I injecting the variable incorrectly in this case? Is there some problem with setting the variable in the dependent ansible-pull roll rather than directly in the ansible role?
It turns out that ansible_version is a magic variable set by Ansible.
Who knew?
Using an arbitrarily different but unused variable name does the trick.
