Overview:-

Building Docker images is fundamental task for developers in containerized environments While the Dockerfile the blueprint, the of building and managing images can be streamlined Bash scripts. This post explores how a-crafted Bash script make Docker image building only more efficient but more reliable.

Prequisites :-

Before diving the Bash scripting for, there are a things you need to in place:

• Docker Installation: Docker is installed and on your machine. can download it from Docker website.

• Basic Knowledge of Docker Understanding of how Docker, what Docker images Docker containers are.

• Bash: Bash script should be installed on your machine.

Procedure :-

1. create a folder with name docker_build and create or move your docker file into the folder.

2. Create a file named build.sh in your docker_build directory.

3. Copy the below bash script into your build.sh file.

#!/bin/bash
set -e

IMAGE=${IMAGE:-"mahira-technology"}
# make a function to build the image
build_image() {
  IMAGE_NAME=$1
  DOCKERFILE=$2

  echo "Building image. IMAGE=$IMAGE_NAME"
  docker build . \
    --file $DOCKERFILE \
    -t "$IMAGE_NAME"
}

build_image $IMAGE Dockerfile

4. Next Open a terminal or command prompt window and get into the docker_build directory. Now run the below command to build a docker image.

./docker_build.sh

Conclusion :-

Bash scripting for Docker builds not only simplifies the process but also enhances the consistency and reliability of your Docker images. Byating this aspect, developers can focus more on core development tasks rather than manual and checks. Embrace the power of Bash scripting and see how it your Docker image building process into a more streamlined and error-free operation.
