Previously we looked at using Localstack to emulate AWS services and speed up the feedback loop during development. In this short post we’re going to look at how to integrate this tool with Terraform to perform some simple testing that can emulate our builds for free and give us some confidence in our code before running it. This post will assume that you have Localstack installed and running. If not, . . .
Recently I’ve been writing some Ansible plays for a personal project and looking around online reminded me just how much people struggle with handling loops. It’s not a huge surprise, whilst the documentation is pretty clear it’s written in a slightly abstract way that can a little difficult to absorb if you’re a newcomer to Ansible, this isn’t aided by the fact that there are several options for looping and . . .
One of the challenges that seems to crop up pretty frequently is reliably simulating a cloud platform or application without having to tediously configure a sandbox environment for every little change. Even when a sandbox is present, the cost of operating them can quickly run out of control and can still need several people to implement even a small change. Localstack is an emulator for an ever growing number of . . .
Without a doubt the topic that seems to confuse people the most when using Ansible Tower is working with Credentials. Especially how to pass multiple credentials from either an external Secret Management source (which we’ve looked at a few times here) or just defining some arbitrary set of credentials and using them in a template. I get emails about this topic from readers on a fairly regular basis and professionally . . .
In a previous article we took a look at the very unwieldy integration of the Istio IngressGateway with an AWS Application Load Balancer, however we didn’t look at any Health Check options to monitor the the ALB via it’s Target Group. A dig around the usual forums suggests that this is confusing a lot of people and it threw me the first time I looked. In post we’ll have a . . .
A question that I’ve been approached about several times recently is how to lookup multiple Hashicorp Vault Secrets and assign them to a single Ansible Tower Credential for use in a Playbook. A while ago I looked at the process of integrating Hashicorp Vault with Ansible Tower (a less that perfect process in the first place) but this has repeatedly led to the same question about multiple Secrets, so in . . .
A short while ago I wrote about setting up Continuous Deployment for Terraform using Bitbucket. Whilst that post is perfectly accurate from a technical standpoint it leads us in to a real minefield and really I don’t think it’s a very good idea to use Terraform in Continuous Deployment at all, rather a system of Continuous Delivery is more effective utilising manual deployments. This post is going to look at . . .
S3 seems to really rule the roost for cloud-based Object Storage and it’s not really a surprise given how flexible it is; often seeing use as hosting for static websites, storing bulk analytics or logs or providing the storage backend for applications amongst many other uses. As S3 content often needs to be presented to the public for anonymous access; the contents of a Bucket are not encrypted by default . . .
This article was going to be a look at how to configure IAM roles to work with EKS Service Accounts, however that topic is already well documented in the AWS docs right here. Whilst there’s nothing wrong with it in a technical sense, I can’t help find it a little clunky, using the AWS CLI and eksctl to get the job done. I’ve been pretty unattracted to eksctl (though it . . .
I’m a long time fan of Juniper networking devices, there seems to be a snobbery against them for reasons I’ve never understood. Imagine my disappointment to find that this was reflected somewhat in the Ansible documentation where JUNOS seems to be the black sheep and the guides are a little patchy. Recently I’ve been having some fun integrating Ansible with JUNOS and this post is going to look at both . . .
