Installing Dagger on a Linux machine is a straightforward task. Simply follow the official instructions to complete this challenge, but make sure to install the CLI to one of the existing PATH locations.

Once the CLI installation is complete, the automation of the playground will try putting it to use. It will trigger the initialization of the Dagger Engine, which might take a minute or two due to the cold start.

Note

The Dagger Engine is conveniently distributed as a container image, which is pulled and started by the Dagger CLI during the first run.

Keep an eye on the outputs of docker images and docker ps while waiting for the task below to complete.

How to Author Challenges on iximiuz Labs

Instead of providing a subpar online editing experience, iximiuz Labs offers a helper CLI tool called labctl, allowing you to use your favorite text editor (or a full-featured IDE) to write content from the comfort of your local machine.

Install labctl CLI

curl -sf https://labs.iximiuz.com/cli/install.sh | sh

This will download and install the latest version of the labctl CLI. You only need to do this once per workstation.

Authorize labctl

labctl auth login

This will open a browser window asking you to authorize labctl to access your account. You need to do it after a fresh install of labctl and repeat it whenever the auth session expires.

Pull challenge content

labctl content pull challenge install-dagger-on-linux

This will create a local copy of the challenge content in a directory named install-dagger-on-linux. You only need to do this once per challenge.

Stream your changes

labctl content push -fw challenge install-dagger-on-linux

Run this command in a separate terminal to continuously upload your changes to the server while editing the challenge in your favorite text editor or IDE.

You can also use labctl to create, list, and delete your content. Learn more about the available commands: labctl content --help
