I am trying to Install RKE2 with Ansible.
but the command for installing RKE2 aren't apt commands
command for installing rke2 is
curl -sfL https://get.rke2.io | INSTALL_RKE2_VERSION=v1.21.6+rke2r1 sh -
I have no idea how to convert this command into playbook code
I did checked other posts about curl - ansible but it doesn't help on my case
Can this work ?
vars:
script_dir: mydir
tasks:
- file:
state: directory
path: "{{ script_dir }}"
- name: download RKE2
get_url:
url: https://get.rke2.io
validate_certs: false
dest: "{{ script_dir }}/install.sh"
mode: 0755
- name: install RKE2
command: "{{ script_dir }}/install.sh"
environment:
INSTALL_RKE2_VERSION: v1.21.6+rke2r1

I'm trying create a Ansible playbook that will read contents of a file and use those contents to install packages on a target machine.
In simpler terms, I want to run this command converted to an ansible playbook
cat ./meta/install-list/apt | xargs apt install -y
./meta/install-list/apt
neofetch
tmux
git
./ansible/playbooks/apt.yaml
- hosts: all
become: true
tasks:
- name: Extract APT packages to install
command: cat ../../meta/install-list/apt
register: _pkgs
delegate_to: localhost
run_once: true
- name: Install APT packages
apt:
name: "{{ _pkgs.stdout_lines }}"
state: latest
./ansible.cfg
[defaults]
inventory = ./ansible/inventory/hosts.yaml
./ansible/inventory/hosts.yaml
---
all:
children:
group-machines:
hosts:
target-machine.local
Command to run playbook
ansible-playbook --ask-become-pass ./ansible/playbooks/apt.yaml --limit group-machine
When running the command, it gets stuck on Extract APT packages to install
NOTE:
these files mentioned above are to be only on machine that is running the command. If possible, I'd like to prevent copying files to target machines and then running the playbooks tasks
PS: new to ansible
I don't see anything in your "Extract APT packages to install" task that should cause it to get stuck... but you don't need that task in any case; you can combine your two tasks into a single task like this:
- hosts: all
become: true
tasks:
- name: Install APT packages
apt:
name: "{{ packages }}"
state: latest
vars:
packages: "{{ lookup('file', '../../meta/install-list/apt').splitlines() }}"
Here we're using a file lookup to read the contents of a file. Lookups always run on the local (control) host.
Note that you could write the above like this as well...
- hosts: all
become: true
tasks:
- name: Install APT packages
apt:
name: "{{ lookup('file', '../../meta/install-list/apt').splitlines() }}"
state: latest
...but I like to keep longer jinja expressions in vars in order to keep the rest of the arguments more readable.
The above answer is more than enough by #Zeitounator. But if you do some formatting to your original file of package list as below
packages:
- neofetch
- tmux
- git
After that you can simply run the playbook like below
- hosts: all
become: true
vars_files: ../../meta/install-list/apt
tasks:
- name: Install APT packages
apt:
name: "{{ packages }}"
state: latest
Now suppose if you are lazy enough to not want to do the formatting then below playbook also will do the trick. Its much cleaner and scalable in my opinion.
---
- name: SHow the packages list
hosts: localhost
become: true
tasks:
- name: View the packages list file
shell: cat ../../meta/install-list/apt
register: output
- name: Install the package
apt:
name: "{{ output.stdout_lines }}"
state: latest

I am creating an ansible playbook in centos7. I get the syntax error every-time I adjust to the syntax error (I even checked spacing and still getting same error):
ERROR! We were unable to read either as JSON nor YAML, these are the errors we got from each:
JSON: No JSON object could be decoded
Syntax Error while loading YAML.
could not find expected ':'
The error appears to be in '/etc/ansible/playbook.yml': line 121, column 5, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:

It looks from what you provided that you don't have a valid yaml format playbook.
You can do quick syntax checks using:
ansible-playbook playbook.yaml --syntax-check
The plays need to be one or more elements of a yaml list, under tasks.
I'd expect your playbook to look something like:
---
# YAML documents begin with the document separator ---
- hosts: hosta,hostb ...etc
tasks:
- name: install MySQL repo
yum:
name: http://dev.mysql.com/get/mysql57-community-release-el7-8.noarch.rpm
state: present
# Three dots indicate the end of a YAML document
...
There are other sections you might have in a playbook, but I've omitted those. The sections like vars, handlers or roles, would be list items at the same indention level as the hosts: and tasks: if you were to need those.
It looks like your issue is here:
name: Install PHP
yum:
enablerepo: "remiremi-php80"
name:
- php
- php-common
- php-cli
- php-gd
- php-curl
- php-mysqlnd
- php-fpm
- php-mysqli
- php-json
state: latest
Notice that state: has to be indented exactly at the same level as enablerepo and name. Make sure you have a space there between state: and latest.
I am using a ansible playbook and it is running fine on my local system but when I run the same playbook on a remote server then it fails due to a error given by chdir module i.e "msg": [Errno 2] No such file or directory, "rc": 2.
Please if anyone can help me figure out what is the exact issue here.

where {{ package_path }} is path to package.json file and {{npm_path}} is /usr/bin/npm( as per your npm path)
I'm writing a playbook that spins up X number of EC2 AWS instances then just installs some software on them (apt packages and pip modules). When I run my playbook, it executes the shell commands on my local system because Ansible won't run unless I specify a host and I put localhost.
In the playbook, I've tried specifying "hosts: all" at the top-level, but this just makes the playbook run for a second without doing anything.
playbook.yml
- name: Spin up spot instances
hosts: localhost
connection: local
vars_files: ansible-vars.yml
tasks:
- name: create {{ spot_count }} spot instances with spot_price of ${{ spot_price }}
local_action:
module: ec2
region: us-east-2
spot_price: '{{ spot_price }}'
spot_wait_timeout: 180
keypair: My-keypair
instance_type: t3a.nano
image: ami-0f65671a86f061fcd
group: Allow from Home
instance_initiated_shutdown_behavior: terminate
wait: yes
count: '{{ spot_count }}'
register: ec2
- name: Wait for the instances to boot by checking the ssh port
wait_for: host={{item.public_ip}} port=22 delay=15 timeout=300 state=started
with_items: "{{ ec2.instances }}"
- name: test whoami
args:
executable: /bin/bash
shell: whoami
with_items: "{{ ec2.instances }}"
- name: Update apt
args:
executable: /bin/bash
shell: apt update
become: yes
with_items: "{{ ec2.instances }}"
- name: Install Python and Pip
args:
executable: /bin/bash
shell: apt install python3 python3-pip -y
become: yes
with_items: "{{ ec2.instances }}"
- name: Install Python modules
args:
executable: /bin/bash
shell: pip3 install bs4 requests
with_items: "{{ ec2.instances }}"
ansible-vars.yml
ansible_ssh_private_key_file: ~/.ssh/my-keypair.pem
spot_count: 1
spot_price: '0.002'
remote_user: ubuntu
The EC2 instances get created just fine and the "wait for SSH" task works, but the shell tasks get run on my local system instead of the remote hosts.
How can I tell Ansible to connect to the EC2 instances without using a hosts file since we're creating them on the fly?
Can you try this if it works.
- name: test whoami
args:
executable: /bin/bash
shell: whoami
delegate_to: "{{ item }}"
with_items: "{{ ec2.instances }}"

I also tried installing the python package MySQL-python using pip but I also got the same error message.
I'm stumped. I don't know what to do anymore.
EDIT: I also tried installing Python 2.7.x on the target machine and made sure that /usr/bin/python is symlinked to Python 2.7.x but I'm still getting the same error. I'm using DJ Wasabi's zabbix-server role
I think you are mixing things up with your delegation. I would simplify things.
Option one: run everything locally. Assumes your DB server is reachable through the network:
- hosts: localhost
connection: local
tasks:
- name: "Debian | Install Mysql Client package"
apt:
name: "{{ item }}"
state: present
with_items:
- mysql-client
- python3-dev
- libmysqlclient-dev
- python3-mysqldb
when:
- zabbix_server_database == 'mysql'
tags:
- zabbix-server
- init
- database
- name: "MySQL | Create database and import file >= 3.0"
mysql_db:
name: "{{ zabbix_server_dbname }}"
encoding: "{{ zabbix_server_dbencoding }}"
collation: "{{ zabbix_server_dbcollation }}"
state: import
target: "{{ ls_output_create.stdout }}"
when:
- zabbix_version is version_compare('3.0', '>=')
- zabbix_database_sqlload
- not done_file.stat.exists
tags:
- zabbix-server
- database
Option two: run the SQL commands from the DB server (then you don't need mysql-python on your local machine, but you need python and mysql-python on the remote server hosting MySQL):
- hosts: dbserver
tasks:
- name: "Debian | Install Mysql Client package"
apt:
name: "{{ item }}"
state: present
with_items:
- mysql-client
- python3-dev
- libmysqlclient-dev
- python3-mysqldb
when:
- zabbix_server_database == 'mysql'
tags:
- zabbix-server
- init
- database
- name: "MySQL | Create database and import file >= 3.0"
mysql_db:
name: "{{ zabbix_server_dbname }}"
encoding: "{{ zabbix_server_dbencoding }}"
collation: "{{ zabbix_server_dbcollation }}"
state: import
target: "{{ ls_output_create.stdout }}"
when:
- zabbix_version is version_compare('3.0', '>=')
- zabbix_database_sqlload
- not done_file.stat.exists
tags:
- zabbix-server
- database
add ansible_python_interpreter in ansible.cfg as follows:
