What is DockSTARTer in Linux?

To put it simply, DockStarTer is a script that assists you in installing and managing Docker, Docker compose, and Docker containers on your Linux system via TUI or CLI.

Note that it doesnโ€™t come with any predefined configurations (like networks, volumes, hosts, etc.) for any of the Docker containers it supports.

However, it makes it much easier than the old way by automating the process of setting up and configuring the Docker environment so that users can run multiple containers in a matter of seconds.

It also includes features like updating and backing up containers. And while I was writing this article, it supported popular container management tools such as Portainer, Watchtower, Jellyfin, Syncthing, etc. (Click here to check the latest apps list)

How to Install DockSTARTer in Linux

DockSTARTer is available for most Linux distributions and can be easily installed (including Docker and Docker compose) via the following methods:

๐Ÿ“
Make sure to be logged in as a non root user with sudo privileges.

Debian, Ubuntu, Pop!_OS, etc.

$ sudo apt install curl git -y
$ bash -c "$(curl -fsSL https://get.dockstarter.com)"
$ sudo reboot

Red Hat, Fedora, CentOS, AlmaLinux, etc.

$ sudo dnf install curl git -y
$ bash -c "$(curl -fsSL https://get.dockstarter.com)"
$ sudo reboot

Arch, Manjaro, EndeavourOS, etc.

$ sudo pacman -Sy curl docker git
$ bash -c "$(curl -fsSL https://get.dockstarter.com)"
$ sudo reboot

Raspbian requires a few extra commands.

$ sudo apt update
$ sudo apt dist-upgrade
$ sudo apt install curl git -y
$ bash -c "$(curl -fsSL https://get.docker.com)"
$ bash -c "$(curl -fsSL https://get.dockstarter.com)"
$ sudo reboot

Note that while writing this article, I personally tested it on Debian and Red Hat based Linux distributions, and it worked well without any errors.

If you encounter any errors or bugs on installation, then feel free to ask for help in the comment section or create a GitHub issue.

How to Set Up and Configure Docker Containers Using DockSTARTer

Once you have Docker, Docker Compose, and DockSTARTer installed, you can straightaway use DockSTARTer to set up and configure applications in a consistent and isolated environment.

1. Execute the following command to run DockSTARTer:

$ ds

2. Now you will be interacting with the following main menu, where you can use the Up and Down arrow keys to navigate and the Enter key to select specific options. For now, navigate to the “Configuration” option and hit enter.

3. And then select “Full setup“.

4. Now you will have the complete list of all the applications supported by this script. By default, “Watchtower” is selected, but you are free to select more than one application by using the Spacebar to select and deselect. Right now, we will only use the “Watchtower” to make it easier for you to understand.

5. Now you will be presented with the default settings for “Watchtower” arranged by the DockSTARTer for you; if you want to keep the default setting and move forward, then select Yes“, otherwise “No“.

6. Next, you will be presented with the default VPN settings arranged by the DockSTARTer for you; choose “Yes“, otherwise “No” to modify them manually.

7. Now, it will prompt you with the default global settings for DockSTARTer, where you can modify the values for the “DOCKERCONFDIR”, “DOCKERSTORAGEDIR”, “DOCKERHOSTNAME”, “PGID”, “PUID”, and “TZ” environment variables.

For instance, I will keep the default settings and select “Yes” to move forward; if you want to edit the settings, then select “No“.

8. Next, you will be asked to choose whether to start the compose or not. Select “Yes” to do so.

Starting the compose

Now, it will get all the Docker images it needs from the internet and set them up based on the settings you gave it.

Setting up and configuring the Docker container

Finally, you can list all the containers that are running on your Linux system to check whether the selected container is running or not.

$ sudo docker ps

Output:

Listing the running containers

Install Another New App

When you want to install another new app using the DockSTARTer, simply execute the following command:

$ ds

And then navigate to “Configuration” => “Select Apps“.

The benefit of using this option is that it will configure the app based on the previously provided settings.

Modify DockSTARTer Settings

Predefined settings (or variables) can be edited even after the container is started by executing the “ds” command and selecting the “Configuration” option. And then select any of the following options to update the respective setting variable value.

Updating the settings

Remove Apps

To remove the apps, first make sure to stop the container by providing the app container id to the following command:

$ sudo docker stop <container-id>

Now, start the DockeSTARTer and navigate to “Configuration” => “Select Apps” and uncheck the apps that you want to remove and select Ok to remove that app.

Update DockSTARTer

To update DockSTARTer, simply execute the following command:

$ sudo ds -u

Or, you can run the DockSTARTer using the “ds” command and choose the “Update DockSTARTer” option.

Updating DockSTARTer

Prune Docker System

If youโ€™re familiar with Docker and Docker compose, youโ€™re probably aware of their caching mechanism, which caches all the containers, networks, volumes, images and build caches that can occupy a good amount of system space over time.

Execute the following command to remove the unused containers, networks, volumes, images and build caches.

$ sudo docker system prune

Or, you can run the DockSTARTer using the “ds” command and choose the “Prune Docker System” option.

Conclusion

Even though this is a great tool for making it easy to manage Docker containers, it has some common problems, such as limited functionality (when users want to set up complex or specific configurations) or maintenance (updating the tool regularly to fix bugs).

So, thatโ€™s all for now. If you have any questions or queries related to this tool, then feel free to ask them in the comment section.

Till then, peace!
