Cadvisor is an open-source monitoring and performance analysis tool developed by Google, that can monitor and collect container resource usage, performance characteristics, and running processes. In this tutorial, we will show you how to install cadvisor on Clear Linux Latest.
Before starting with the installation of cadvisor, you need the following prerequisites:
Cadvisor is deployed as a Docker container, and therefore Docker needs to be installed on your system. To do that, use the following command:
sudo swupd bundle-add containers-basic
You can pull the official cadvisor Docker container from the Docker Hub repository. To download the container, run the following command:
sudo docker pull google/cadvisor
Or, you can also build your own container from the cadvisor source code, which is available on the Github repository.
Once you have downloaded the cadvisor Docker container, you can run it using the following command:
sudo docker run \
--volume=/:/rootfs:ro \
--volume=/var/run:/var/run:ro \
--volume=/sys:/sys:ro \
--volume=/var/lib/docker/:/var/lib/docker:ro \
--publish=8080:8080 \
--detach=true \
--name=cadvisor \
google/cadvisor:latest
The above command will run the cadvisor container with the following options:
--volume=/:/rootfs:ro - Mount the root filesystem as a read-only volume.--volume=/var/run:/var/run:ro - Mount the Docker runtime as a read-only volume.--volume=/sys:/sys:ro - Mount the sysfs filesystem as a read-only volume.--volume=/var/lib/docker/:/var/lib/docker:ro - Mount the Docker data store as a read-only volume.--publish=8080:8080 - Publish port 8080 of the container to the host system so that you can access the cadvisor web UI.--detach=true - Run the container in the background.--name=cadvisor - Give the container a name to make it easier to manage and interact with.To verify the installation of cadvisor, open your web browser and visit http://localhost:8080 or http://<your_server_ip_address>:8080. You should see the cadvisor web UI, where you can view and analyze the performance metrics of your containers.
In this tutorial, you learned how to install cadvisor on Clear Linux Latest. Cadvisor is a useful tool to monitor and analyze container performance metrics. If you have any questions, feel free to leave a comment below.
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!
