How to Install Docker on OpenBSD

Introduction

Docker is an open-source containerization platform that allows developers to easily create, deploy, and run applications in containers. In this tutorial, we will show you how to install Docker on OpenBSD.

Prerequisites

Before you begin, make sure your OpenBSD system is up-to-date and has the following prerequisites installed:

• curl - a command-line tool for transferring data
• tar - a command-line utility for archiving files
• pkg_add - a package installation tool in OpenBSD

Step 1: Download Docker

To download Docker on OpenBSD, you can use the following curl command:

$ curl -fsSL https://get.docker.com | sh

This command will download the Docker installation script and execute it.

Step 2: Verify the Installation

After the installation is complete, you can verify that Docker is installed on your system by running the following command:

$ docker version

If Docker is installed correctly, you should see its version information.

Step 3: Configure Docker to Run on Startup

To configure Docker to start automatically at system startup, you need to create a new service file called /etc/rc.d/docker with the following content:

#!/bin/sh
#
# startup script for Docker daemon
#
#
daemon="/usr/local/bin/dockerd"
daemon_flags="-H unix:///var/run/docker.sock"
. /etc/rc.d/rc.subr
rc_bg=YES
rc_need=network

rc_cmd $1

Then, set the file permissions to executable:

$ chmod +x /etc/rc.d/docker

Finally, enable the service to start at boot time by running:

$ rcctl enable docker

Step 4: Start Docker

To start Docker, run the following command:

$ rcctl start docker

Conclusion

In this tutorial, we have shown you how to install Docker on OpenBSD. You can now start using Docker to create, deploy, and run applications in containers.

If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!

Alternatively, for the best virtual desktop, try Shells!
