How to Install cAdvisor on NixOS Latest

cAdvisor (Container Advisor) is a tool that collects performance statistics and resource usage data from container systems like Docker and Kubernetes. This tutorial will guide you through the installation of cAdvisor on NixOS Latest using Github repository.

Prerequisites

Before proceeding with the installation process, make sure that you have the following prerequisites:

A running instance of the NixOS latest version.
A user account with sudo privileges.

Step 1: Clone the cAdvisor Repository

The first step is to clone the cAdvisor repository from the Github repository using the following command:

$ git clone https://github.com/google/cadvisor.git

This will download the cAdvisor source code to your local machine.

Step 2: Install Docker

cAdvisor runs in a Docker container, so you need to have Docker installed on your system. Follow these steps to install Docker:

Update the package list by running the following command:
```
$ sudo nix-channel --update
```
Install Docker by running the following command:
```
$ sudo nix-env -iA nixos.docker
```
Start the Docker service by running the following command:
```
$ sudo systemctl start docker
```

Step 3: Build the cAdvisor Container Image

The next step is to build a Docker image for cAdvisor by running the following command:

$ cd cadvisor
$ sudo docker build -t cadvisor .

This will build a Docker image for cAdvisor and tag it as “cadvisor”.

Step 4: Run the cAdvisor Container

Now you can run the cAdvisor container by executing the following command:

$ sudo docker run --volume=/:/rootfs:ro --volume=/var/run:/var/run:rw --volume=/sys:/sys:ro --volume=/var/lib/docker:/var/lib/docker:ro --publish=8080:8080 --detach=true --name=cadvisor cadvisor

This command will start a cAdvisor container and expose port 8080. Once the container is running, you can access cAdvisor by opening a web browser and navigating to http://localhost:8080.
