In this tutorial, you will learn how to install Healthchecks on your Fedora CoreOS Latest system. Healthchecks is an open-source tool that helps you monitor the availability and performance of your applications and services. The process involves the following steps:
Before proceeding, make sure you have met the following requirements:
Healthchecks requires Docker to run. If you have not installed Docker yet, use the following command to install it on your system:
$ sudo dnf install docker
After the installation is complete, enable and start the Docker service:
$ sudo systemctl enable docker
$ sudo systemctl start docker
Before installing Healthchecks, you need to create a data directory to store the SQLite database and configuration files. Use the following command to create a new directory:
$ sudo mkdir /var/lib/healthchecks
Next, you need to generate a secret key that will be used to secure your Healthchecks installation. You can generate the key using the following Python command:
$ python3 -c 'import secrets; print(secrets.token_hex(32))'
Copy the output of the command to a safe place; you will need it later.
To install Healthchecks, use the following command:
$ sudo docker run -d \
--name=healthchecks \
-e "SECRET_KEY=<insert-your-secret-key>" \
-v /var/lib/healthchecks:/data \
-p 127.0.0.1:8000:8000 \
healthchecks/healthchecks:latest
Replace <insert-your-secret-key> with the secret key you generated in Step 2.
This command will download the Healthchecks image from Docker Hub and start a new container named healthchecks. The -v option maps the /var/lib/healthchecks directory to the container's /data directory, which is where the SQLite database and configuration files will be stored.
The -p option maps port 8000 on the container to port 8000 on the host, allowing you to access the Healthchecks web interface from your browser. Note that the interface will only be available on the loopback interface (127.0.0.1), which means that only connections from the same system will be accepted.
To check that Healthchecks is running, use the following command:
$ sudo docker ps
This will show a list of running containers, including the healthchecks container.
Finally, open your web browser and visit http://localhost:8000 to access the Healthchecks web interface. You should see the dashboard with no checks configured.
Congratulations, you have successfully installed Healthchecks on your Fedora CoreOS Latest system!
