Docker Formatter

This Go project is a Docker formatter tool that formats the output of Docker commands such as docker ps and docker ps -a. The tool enhances readability and makes the output easier to parse and work with.

docker ps output is:

our docker fps (formatted ps) output will be:

Features

  • Formats the output of docker ps for running containers.
  • Formats the output of docker ps -a to include stopped containers as well.

currently this formatter only formats those two docker commands, other commands may be added later

Prerequisites

Before using this tool, make sure you have the following installed:

Installation

1. Clone the repository:

git clone https://github.com/tazbin/docker-formatter.git

Navigate to the directory

cd docker-formatter

2. Create the executable

go build -o docker-formatter main.go

3. Move the executable in the usr/local/bin directory

mv docker-formatter /usr/local/bin

4. Update your shell configuration

You need to add the following snippet to your shell configuration file. Since I'm using Zsh, I will add it to the ~/.zshrc file.

For other shells, refer to the appropriate configuration file (~/.bashrc for Bash or ~/.profile for sh).

Open your shell configuration file:

nano ~/.zshrc

Add the following function:

docker() {
    if [ "$1" = "fps" ] && [ "$2" = "-a" ]; then
        /usr/local/bin/docker-formatter docker ps -a
    elif [ "$1" = "fps" ]; then
        /usr/local/bin/docker-formatter docker ps
    else
        command docker "$@"
    fi
}

5. Apply shell changes

After modifying .zshrc, run the following command to apply the changes

source ~/.zshrc

6. Running custom docker commands

Running docker fps command will show output in formatter way
