About Docker — how have you worked with it?

I worked with Docker for containerizing applications and simplifying their deployment. The main tasks I performed were:

• Creating Dockerfiles to build images with the required environment.
• Running containers locally for testing and development.
• Using Docker Compose to orchestrate multiple services (e.g., application + database).
• Writing scripts to automate the building and deployment of containers.

An example of a simple Dockerfile for a Go application:

FROM golang:1.20-alpine
WORKDIR /app
COPY . .
RUN go build -o myapp
CMD ["./myapp"]

This allows building and running the application in an isolated container, which facilitates portability and scalability.
