quickstart to learn ansible playbook provisioning tools.

Ansible Quickstart

Installation

Ansible

we need to install ansible via pip (Python Package Manager):

pip install ansible

Manage server deployed in idcloudhost provider

We use terraform to automate managing our server, you can do it manually or use any preferred provisioning tools or API.

Variables

you need to create file terraform.tfvars in terraform/:provider/terraform.tfvars as following example:

credentials = {
  auth_token = "supersecret"
}

ansible_vm = {
  username           = "user"
  initial_password   = "supersecret"
  billing_account_id = 123456789
}

Instance Creation

In order to create the instance:

terraform -chdir=terraform/:provider/ init
terraform -chdir=terraform/:provider/ plan
terraform -chdir=terraform/:provider/ apply --auto-approve

Host IP

created instance's public ip can be seen as an execution output.

Instance Removal

In order to delete the instance after usage

terraform -chdir=terraform/:provider/ destroy --auto-approve

Working with ansible

Preparation

configure hosts and variables with real instance ip

cp hosts.example hosts
cp group_vars/aws.yaml.example group_vars/aws.yaml
cp group_vars/idcloudhost.yaml.example group_vars/idcloudhost.yaml

Check Inventory

you need to check if inventory has been setted up correctly using :

ansible-inventory -i hosts --list

Ping Host Server

you need to check if ansible has been connected to your server using:

ansible idcloudhost -m ping -i hosts

Hello World

using hello world playbook you can test ansible automation

ansible-playbook -i hosts playbooks/helloworld/helloworld.yaml

PostgreSQL Database Management

1. install postgresql using postgresql/install.yaml playbook

ansible-playbook -i hosts playbooks/postgresql/install.yaml

2. create test database using postgresql/database.yaml playbook

cp playbooks/postgresql/vars.example.yaml playbooks/postgresql/vars.yaml
ansible-playbook -i hosts playbooks/postgresql/database.yaml

3. create test table using postgresql/table.yaml playbook

ansible-playbook -i hosts playbooks/postgresql/table.yaml
