Introduction

Running the reformat-all script requires multiple dependencies. To overcome this problem, instead of trying to install all the necessary dependencies on your own, you can easily build a Docker image and run the script inside a Docker container based on this image.

Who Is This Guide For?

Do you want to run the reformat-all and the fix-spelling script easily and without any hassle? You've come to the right place.

This is a step-by-step guide. Just follow the steps and you are good to go!

Prerequisites

  • Docker for Linux containers has to be preinstalled. Please refer to https://docs.docker.com/install/ if you haven't installed it yet. Your host OS should better be Linux, because we are going to use your current Linux user ID for building the image.
  • Basic knowledge of Docker (not mandatory)

What to Begin With?

1. Build Your Own Docker Image

Now you are going to build your own Docker image based on Debian.

From the source root directory run the following command:

docker build -t buildelektra-sid \
	--build-arg JENKINS_USERID=$(id -u) \
	--build-arg JENKINS_GROUPID=$(id -g) \
	-f scripts/docker/debian/sid/Dockerfile \
	scripts/docker/debian/sid/

The build process depends on your Internet connection speed and the overall performance of your hardware. Most likely, it will take at least 5 minutes. Please be patient. Once you have built the image, you can reuse it multiple times.

The image tag buildelektra-sid we suggested can be replaced by a name of your own choosing. Note that currently our sid image is the only one with all the necessary tools installed.

2. Run the Docker Container

After you built the image, you can execute a container like this:

docker run -it --rm \
	-v "$PWD:/home/jenkins/workspace" \
	-w /home/jenkins/workspace \
	buildelektra-sid

Again, if you changed the image tag buildelektra-sid, please change it above as well.

3. Running the Script

After starting the container, you should be automatically inside it in the working directory /home/jenkins/workspace.

Now run the script:

scripts/dev/reformat-all

All your files should be reformatted afterwards.

To also fix spelling errors in your files, run the script:

scripts/dev/fix-spelling

All your spelling errors should be fixed afterwards.
