When building complex IT structures with a whole team, but also by yourself can take some time. While you go on and load software providing network services on different hosts you may want to keep track of what is up and what is not.
There are complex tools like Zabbix and ZenOSS which are fine to support a operations process. But just to keep a list of what is functioning a simple uptime checker with some way to report problems to Telegram or email is great! Uptime Kuma is just that.
It is simple in what it does, just connects on a network port, grep some text on a website or a ping. Simple in how it installs. Just loading a container, saving persistent data in a volume if needed.
sudo podman volume create uptime-kumaThen load the container using that container
sudo podman run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:1
From time to time, you will be hinted at the availability of updates. The following to update the container:
sudo podman pull louislam/uptime-kuma:1

docker.io/louislam/uptime-kuma:1Then we need to stop the container running the old code and start the new container
sudo podman stop uptime-kuma
sudo podman rm uptime-kumaThen repeat the loading of the container using the existing volume
sudo podman run -d --restart=always -p 3001:3001 -v uptime-kuma:/app/data --name uptime-kuma louislam/uptime-kuma:1Adding monitoring targets
