In this post, I’ll document how to use AWS CLI to delete a few Lightsail resources. I have never done this before, so this would be a good exercise for me. To make it less boring, I’m writing this post while I’m deleting these resources. First step, I need to look for the instance name [1]. ❯ aws lightsail get-instances --query 'instances[].name' [ "WordPress-1" ] The above output is the name of the instance I’d like to delete. With its name, the instance can be deleted using the following command line [2]: ...

If you have an ElastiCache Memcached cluster that you no longer need, it’s better to delete it. Dno’t believe me? Even AWS said so too: It is almost always a good idea to delete clusters that you are not actively using. Until a cluster’s status is deleted, you continue to incur charges for it.

This is a quick note on how to delete VPC endpoints that are no longer needed with AWS CLI. First, we need to find all the vpc-endpoints-ids [1]. ❯ aws ec2 describe-vpc-endpoints --query 'VpcEndpoints[].VpcEndpointId' [ "vpce-097008f8d26caxxxx", "vpce-07aaeabdefd8xxxx", "vpce-0bc6d548ff2e0xxxx" ] Note: I replaced the last 4 digit with ‘xxxx’. It’s a good idea to try out without really deleting the VPC endpoints by supplying --dry-run to the command below: ❯ aws ec2 delete-vpc-endpoints --vpc-endpoint-ids vpce-097008f8d26caxxxx vpce-07aaeabdefd8xxxx vpce-0bc6d548ff2e0xxxx --dry-run An error occurred (DryRunOperation) when calling the DeleteVpcEndpoints operation: Request would have succeeded, but DryRun flag is set. Let’s delete all of the 3 resources: ...

Have you ever been asked or wonder how to learning a programming language? If not, then you can skip this blog post. :-) At work, a coworker said to me “I want to learn a programming language. Where do I start or how do I even start it?” I was asked this question because I had explicitly expressed my interest to my teams that I like programming a lot, though programming is not being used my professional career at the moment. ...

In my previous post, I showed how to install helm CLI on a server/instance running AlmaLinux 9. Now, I will share how to use helm to install the Ingress-Nginx Controller for a Kubernetes cluster. We install a package known as “chart” from a Helm repository. Initially, there is no repo, and can be seen below: $ helm repo list Error: no repositories to show In order to install Ingress-Nginx Controller, I first need to add a new repository. ...
