Introduction In this article we will test how to lint and get automatic checks in our github pull requests for our terraform code using reviewdog and the tflint github action, this is particularly useful to prevent unwanted changes or buggy commits to be merged into your principal branch whatever that is. In order for this to work you just need to configure a Github action in your repo and that’s it, you don’t need to generate any token or do any extra step.

Introduction In this article we will continue where we left off the forward project last time, in this article we will use gitlab-ci to test, build and push the image of our operator to dockerhub. Gitlab offers a pretty complete solution, but we will only sync our repo from github and set a basic pipeline to test, build and push our docker image to the registry, note that I do not have any kind of affiliation with gitlab, but I like their platform.

Introduction In this article we will see how to use cat, netcat and socat at least some basic examples and why do we have so many cats… Also sorry for the awful recordings, but couldn’t figure out why it looks so bad with tmux. cat Cat as you might have guessed or know already is to con-cat-enate things, when used in conjunction with the shell redirections it can do a lot of powerful things but it’s often used when it’s not needed due to that, let’s see some examples.

Introduction In this article we will see how to use kubebuilder and Kind to create a local test cluster and an operator, then deploy that operator in the cluster and test it, the repository with the files can be found here, also if you want to learn more about the idea and the project go: forward. Basically what the code does is create an alpine/socat pod and you can specify the host, port and protocol and it will make a tunnel for you, so then you can use port-forward or a service or ingress or whatever to expose things that are in another private subnet, while this might not sound like a good idea it has some use cases, so check your security constraints before doing any of that in a normal scenario it should be safe, it can be useful for testing or for reaching a DB while doing some debugging or test, but well, that is for another discussion, the tools used here is what makes this so interesting, this is a cloud native application, since it native to kubernetes and that’s what we will explore here.

Introduction Easy method to report spam to SpamCop.net using GMail, this helps to reduce the true Spam from unknown sources, since for some reason I started to get like 40 emails per day (all went to spam), but it is still somewhat annoying, so I started reporting it to spamcop, this alternative method doesn’t need a script and it’s really easy to do as well, same result as with the script from the previous post.

Introduction This post is a bit different from the others in the sense that it’s a small “tool” I did to ease spam reporting to SpamCop.net, this helps to reduce the true Spam from unknown sources, since for some reason I started to get like 40 emails per day (all went to spam), but it is still somewhat annoying, so I started reporting it to spamcop, but the process was kind of slow and I got tired of that quickly, so I created this “script” to make things easier.

Introduction In this article we will see the basics to have tests for your terraform code using a re-usable pattern, we will use the code from the last article Serverless authentication with Cognito, so refer to that one before starting this one if you want to know how did we get here. Also as a side note this is a very basic example on how to get started with terratest.
