cAdvisor is a container monitoring tool used to gather and analyze performance metrics and statistics from Docker containers. In this tutorial, we will cover step-by-step instructions on how to install cAdvisor on Arch Linux.
Before installing cAdvisor, you should ensure that your system meets the following requirements:
First, we will update the Arch Linux system to ensure that all the necessary dependencies are up-to-date. In the terminal, run the following command:
sudo pacman -Syu
This command will fetch the latest updates for your system, upgrade all the installed packages, and install any missing dependencies.
cAdvisor is available as a container image, which can be downloaded from the Docker Hub. To install cAdvisor, run the following command in the terminal:
sudo docker pull google/cadvisor
This command will download the latest version of cAdvisor from the Docker Hub and store it locally.
Now that we have downloaded the cAdvisor image, we can run it as a container with 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 --volume=/dev/disk/:/dev/disk:ro --publish=8080:8080 --detach=true --name=cadvisor google/cadvisor:latest
This command will start the cAdvisor container, bind ports 8080 on the Docker host to the same port on the cAdvisor container, and give it a name "cadvisor". The --volume flags mount the host's file systems and devices as read-only to the container.
Once the container is running successfully, you can access the cAdvisor dashboard by opening a web browser and navigating to the following URL:
http://localhost:8080
This will display the cAdvisor dashboard with various graphs and charts showing container performance metrics and resource utilization.
cAdvisor is a useful tool for monitoring and analyzing performance metrics of Docker containers. By following this tutorial, you should now have a fully functional cAdvisor installation on Arch Linux.
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!
