You may wonder if it’s possible to rename an Elasticsearch index while doing a restore from an Elasticsearch snapshot but keeping the existing index as it is. Let’s see the scenario. I have an index devcoops and have a backup snapshot of it as well. I will…

It’s not a new thing to loop through Terraform outputs though, so here are a few solutions that could help since count can’t be used as part of the output itself.

By default, once you enable the Compute Engine API in GCP, two Google-managed service account principals will be created Compute Engine default service account and Google APIs service account. Both assigned with the Editor role.

If you want to update your currently running ECS tasks and launch new ones, there is a cool option --force-new-deployment which will start a new deployment of the service and recycle all the tasks. It’s very useful if you need to refresh the containers and…

Yes, you read that right. I deleted almost 80% of the code from the Redis bitnami container image on Docker Hub and it still does…

Given that Redis supports optional authentication, it would be outrageous to deploy it to a public subnet hence exposing to the Internet. So, once you setup and configure Redis in a private subnet, bind the address, add a firewall rule, and on top of that…

While installing some Certbot packages I stumbled upon the No package python3-certbot-nginx available. error. Let’s take a look.

For today’s Terraform error of the week series we are going to take a look at the following one: │ Error: Failed to install provider │ │ Error while installing terra-farm/xenorchestra v0.23.2: the current package for │ registry.terraform.io/terra-farm/xenorchestra…

It’s been a while since I’ve encountered any issues and errors related to Docker. It has to do with one of two things. Docker became more stable, or I’m not spending time on it as I was before. Either way, here’s the error I’ve faced this week when I was…

Some of your Docker Debian-based containers can be killed due to heavy processes running inside the container. If your preferred choice is the top command, most likely you will get the following error: top: command not found. Let’s see how to install top…

There are two important things to differentiate when registering and working with apps in Azure AD: App Registrations and Enterprise Applications.

Containers for fun and profit! So you're now officially excited about Docker and container...

single file distributable web server

If you get this kind of error: docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "/bin/bash": stat /bin/bash: no such file or directory: unknown. or ERRO[0000]…

Two more arguably confusing identity objects in Azure AD – Service Principal and Managed Identities. Let’s tackle them down by defining what they are and how they distinguish from each other.

As part of my new job, I'm learning a lot more about the mysteries of the Domain Name System than any mortal should know I thought possible. The humble unix dig command allows you to query all sort of DNS information. For example, to see name server records…

In one of the last Azure posts, I wrote about the differences between Service Principal and Managed Identities. Since there are two types of MIs – User-assigned and System-assigned, I’m going to cover them both broadly.

Getting Microsoft Graph API Delegated and Application permission IDs are definitely hard to find, if you are doing things right – the programmatic way.

Since there isn’t any resource_enabled = false feature developed by Terraform yet, here’s a quick hack to enable / disable resources.

Another probably valuable Terraform nugget to share. Suppose that you want to get the current working directory name only for some reason. There are few helpful built-in references and functions that could help.
