In this tutorial, we will guide you through the process of installing cadvisor, an open-source container monitoring tool from GitHub, on Fedora Server. Before we begin, make sure you have administrative privileges to install software on your system.
Cadvisor is a Docker container that requires Docker to be installed on your system. If you don't have Docker already installed, run the following command to install it:
sudo dnf install docker-ce
Once Docker is installed, start and enable the Docker service with the following command:
sudo systemctl start docker
sudo systemctl enable docker
To download and run the cadvisor container, run 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 google/cadvisor:latest
Explanation of the above command:
--volume=/:/rootfs:ro: mounts the root filesystem as read-only--volume=/var/run:/var/run:rw: mounts the Docker daemon socket to communicate with the host Docker daemon--volume=/sys:/sys:ro: mounts the sysfs filesystem as read-only--volume=/var/lib/docker/:/var/lib/docker:ro: mounts the Docker images and container data as read-only--publish=8080:8080: maps the container's port 8080 to the host's port 8080--detach=true: runs the container in the background--name=cadvisor: gives the container a nameOnce the docker container is up and running, open a web browser and go to http://localhost:8080 to view the cadvisor dashboard. You should see a dashboard similar to the following:
Congratulations! You have successfully installed and configured cadvisor on your Fedora Server. You can now use cadvisor to monitor the performance of your containerized applications.
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!
