How to Install Docker Compose on OpenBSD

Docker Compose is a tool that enables the deployment and management of multiple containers in a single environment. In this tutorial, we will guide you through the steps of installing Docker Compose on OpenBSD.

Prerequisites

Before we start installing Docker Compose, it is essential to check whether the following dependencies are installed on your OpenBSD system.

  • Docker must be installed on your OpenBSD machine.
  • curl or wget, which is used to download Docker Compose.
  • A basic knowledge of the OpenBSD command line interface (CLI) is required.

Step 1 - Install curl or wget

We need curl or wget to download the Docker Compose binary. If you don’t have these tools installed, you can install one of them using the OpenBSD package manager called pkg_add.

Run the following command to install curl:

$ sudo pkg_add -v curl

OR

Run the following command to install wget:

$ sudo pkg_add -v wget

Step 2 - Download Docker Compose

We can download the Docker Compose binary from Docker’s official website. Go to the Docker Compose installation page in your browser.

https://docs.docker.com/compose/install/

Copy the link to the latest version of Docker Compose, which is in the form of a URL. We will use this link to download the Docker Compose binary.

Step 3 - Install Docker Compose

To install Docker Compose, we need to download the binary file and place it in the /usr/local/bin directory.

Use the following command to download the Docker Compose binary file:

$ sudo curl -L https://github.com/docker/compose/releases/download/<VERSION>/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

OR

Use the following command to download the Docker Compose binary file with wget:

$ sudo wget https://github.com/docker/compose/releases/download/<VERSION>/docker-compose-$(uname -s)-$(uname -m) -O /usr/local/bin/docker-compose

Note: Replace <VERSION> with the latest Docker Compose version.

Now, we need to make the docker-compose binary executable by running the following command:

$ sudo chmod +x /usr/local/bin/docker-compose

To verify the installation, run the following command:

$ docker-compose --version

If you get the version number of Docker Compose in the output, it means that the installation was successful.

Conclusion

In this tutorial, we have shown you the steps to install Docker Compose on OpenBSD. By following these steps, you can run multiple containers in a single environment using Docker Compose.
