|
Let's start at the beginning.
|
||
|
|
|
||
|
|
If we want to automate our infrastructure then we first need to create it. This could be done manually or we can automate it.
|
||
|
|
|
||
|
|
Popular tools for this include Terraform and Pulumi, but Ansible also includes modules to interface with hosting providers such as Amazon Web Services, Microsoft Azure, DigitalOcean, and Linode.
|
||
|
|
|
||
|
|
By using one of these tools, you can programatically provision a new, blank server that is ready for you to be configered.
|
||
|
|
|
||
|
|
For example, to [create a DigitalOcean droplet](https://docs.ansible.com/ansible/latest/collections/community/digitalocean/digital_ocean_module.htm):
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
---
|
||
|
|
- community.digitalocean.digital_ocean_droplet:
|
||
|
|
image: ubuntu-20-04-x64
|
||
|
|
name: mydroplet
|
||
|
|
oauth_token: "..."
|
||
|
|
region: sfo3
|
||
|
|
size: s-1vcpu-1gb
|
||
|
|
ssh_keys: [ .... ]
|
||
|
|
state: present
|
||
|
|
wait_timeout: 500
|
||
|
|
register: my_droplet
|
||
|
|
```
|
||
|
|
|
||
|
|
Running this playbook will create a new Droplet with the specified name, size, and operating system, and within the specified region.
|
||
|
|
|
||
|
|
If you needed to create a separate database server or another server for a new environment, then the file can be updated and re-run.
|
||
|
|
|
||
|
|
[Creating an Amazon EC2 instance](https://docs.ansible.com/ansible/latest/collections/amazon/aws/ec2_instance_module.html#ansible-collections-amazon-aws-ec2-instance-module) looks very similar:
|
||
|
|
|
||
|
|
```yaml
|
||
|
|
---
|
||
|
|
- amazon.aws.ec2_instance:
|
||
|
|
image_id: ami-123456
|
||
|
|
instance_type: c5.large
|
||
|
|
key_name: "prod-ssh-key"
|
||
|
|
name: "public-compute-instance"
|
||
|
|
network:
|
||
|
|
assign_public_ip: true
|
||
|
|
security_group: default
|
||
|
|
vpc_subnet_id: subnet-5ca1ab1e
|
||
|
|
```
|
||
|
|
|
||
|
|
This doesn't apply just to servers - you can also use Ansible to create security groups and S3 buckets, manage SSH keys, firewalls, and load balancers.
|
||
|
|
|
||
|
|
Once we have our infrastructure in place, we can start using Ansible to set and manage its configuration, which we'll do in tomorrow's email.
