The ramblings of a computer geek
You can quickly create an Ansible Directory structure using something like the following example. In my example the Ansible directory is just within my Home Directory, I then have a directory called “Plays” where the Ansible Play files are stored and another one called “Roles” where the roles are stored. If say we wanted to […]

Following on from a previous article https://geekmungus.co.uk/?p=4510 we now investigate some more into using Ansible for configuration management and installations. As something we can use as an example, we’re going to setup a simple Bind DNS server, which we can use to explore how to manage the installation of Bind and it’s configuration within Ansible. […]

Although SSH is preferred, if you want to use Git’s credential helper here’s two simple options, note you’ll probably not want to use the Credentials Helper method, because it stores the credentials in a plain-text file, albeit in your home directory, but still. Using the Credentials Helper, you won’t have to re-enter your username and […]

I’m trying a simple example Ansible configuration, I have three Raspberry Pi, each with Ubuntu Linux 22.04.4 LTS installed, one I’m going to use as the Ansible Workstation, then use it to configure the other two servers for different use cases. Its a simple setup, but helps build understanding. My Ansible workstation is called dev1 […]

The Amazon Elastic Container Service (ECS), specifically Fargate allows you to run containers on an ad-hoc basis. The following guide assumes you have already deployed an Amazon Elastic Container Registry (ECR), built your image, pushed it to the ECR and have obtained the Repository URI. The guide also uses local Terraform state, please see the […]

The below gives a simple example showing how you can deploy a containerised workload: a NGINX web server in this example which has two (or more) containers (tasks) running on AWS Fargate, presented behind a “Service” definition which is then presented to the Internet via an Application Load Balancer (ALB) where a certificate is obtained […]

The Amazon Container Registry (ECR) allows you to store the images within the cloud, for the purposes of this example we’ll use a simple container using a Dockerfile that creates an Apache web server that says “Hello World!”. Repository The example Terraform definitions can be found within Gitlab: Step 1 – Deploy Terraform You first need […]

You can use EC2 Instance Session Manager to give you direct console access without the need for an SSH connection direct to the instance (which can cause some security issues), instead you can get the same kind of access via the AWS CLI. These instructions assume you have an EC2 instance already setup and working […]

Elastic IP Addresses (EIP) are great as they provide you with a static IP address which you can use for an endpoint to your application, but when you are automating things with Terraform, you don’t want it to be continually re-created or that IP address will change, and if you have DNS records pointing at […]

Building upon the example Simple Terraform Docker Example (Ubuntu Linux), we’ll store our Terraform State in AWS S3 Bucket, rather than just locally on the machine running Docker. Yes, I know its not a very useful example, but it simply illustrates the mechanism and how it can be used for more useful and complex deployments. Storing […]
