Okay, so I’ve been messing around with this thing called “Kaniko” lately, and let me tell you, it’s been a bit of a ride. The whole point is to build container images without needing the Docker daemon, which is kinda cool if you’re, like, super into Kubernetes or something. Anyway, I wanted to see if I could get it to spit out an image with a nice, vibrant blue – hence the “réale blue” part.
First, I grabbed the Kaniko executor image. I think I just pulled it from the Google Container Registry, or something like that. Honestly, I just followed some tutorial I found online – don’t judge!
The Setup
- I made a simple Dockerfile. Nothing fancy, just a base image and some commands to, you know, install stuff and maybe copy some files. The key was adding the command to set up the color.
- I created the Dockerfile like this:
FROM alpine
RUN echo "This is going to be blue... eventually!"
- I also whipped up a little config file for Kaniko. This is where you tell it where to push the image, and stuff like that. I’m not gonna lie, I kinda struggled with this part. Getting the authentication right was a pain.
- Then came the fun part – actually running Kaniko. I used some command-line magic (okay, I copied and pasted it) to tell Kaniko to build the image using my Dockerfile and push it to my registry.
It churned away for a bit, spewing out a bunch of logs. Seriously, it was like watching paint dry… or, I guess, watching code compile. But then, BAM! It finished.
I checked my container registry, and there it was! My “reale blue” image. Now, I’m not saying it was the most beautiful shade of blue ever created, but hey, it was blue! And I built it without Docker, which is kinda neat, I guess.
I’m not 100% sure I’ll use Kaniko for everything from now on, but it’s definitely a cool tool to have in the toolbox. It’s kinda like that weird wrench you only use once a year, but when you need it, you really need it.
