After building a Docker image faster, I wanted to build it for the K8s cluster. Running the container on the local machine isn’t the same as running it on a cluster. I’m packaging a Go application in my example. But the same principles apply to any other language. Starting Dockerfile I’m starting with the following Dockerfile(Dockerfile_1): ARG GO_VERSION=1.20.3 FROM golang:${GO_VERSION}-buster as builder WORKDIR /app COPY go.mod go.sum /app/ RUN go mod download -x COPY ....

During building services, we often need to build docker images. We do it multiple times a day. It can be a time-consuming task. Locally we only notice it a little, but in CI/CD pipelines, it can be a problem. In this post, I will show you how to speed up the process. I will show you how to use a cache, layer your Dockerfile, and use multi-stage builds, to make your builds faster....

As a developer, when working on a service, you face a problem with the working environment. And when I say working environment, I do not think about IDEs, stacks, OS, libraries, etc. I’m thinking about the environment where our services live. These days, our services are usually packed inside some container and put in some kind of distributed system. Most containers and other moving parts are controlled by Kubernetes, Nomad, and similar orchestration systems....
