OpenFaaS is an open-source serverless platform that enables users to deploy and manage their own functions in any language. In this tutorial, we will show you how to install OpenFaaS on Clear Linux Latest.
Before we begin with the installation of OpenFaaS on Clear Linux Latest, please make sure that you have the following prerequisites:
faas-cli installed (optional)git command-line tool installedOpen a terminal and update the system with the following command:
sudo swupd update
Next, we need to make sure that the curl command-line tool is installed. If it isn't installed, you can install it using the following command:
sudo swupd bundle-add curl
In this step, we will clone the OpenFaaS repository from GitHub to our local system. Open a terminal and run the following command:
git clone https://github.com/openfaas/faas
This command will clone the OpenFaaS Git repository to the current directory.
In this step, we will install OpenFaaS by running its installer script. Change your current directory to the faas directory by running the following command:
cd faas
Once inside the faas directory, run the following command:
./deploy_stack.sh
This command will start the installation process of OpenFaaS. Once the installation process is complete, you should see the OpenFaaS Gateway running in the terminal. You can now access the OpenFaaS Gateway by opening your browser and visiting http://localhost:8080.
In this step, we will test OpenFaaS by deploying a sample function. First, we need to deploy the OpenFaaS CLI tool by running the following command:
curl -sL https://cli.openfaas.com | sudo sh
Next, we need to log in to the OpenFaaS Gateway by running the following command:
faas-cli login -g http://localhost:8080 -u admin -p changeme
This command logs in to the OpenFaaS Gateway with the default username and password. Note that you should change the default password as soon as possible.
Next, we need to deploy a sample function by running the following command:
faas-cli deploy -f https://raw.githubusercontent.com/openfaas/faas-cli/master/samples.yml
This command deploys a sample function defined in the samples.yml file.
Once the deployment process is complete, you can access the function by opening your browser and visiting http://localhost:8080/function/helloworld.
You should now see the output of the function on your browser.
Congratulations! You have successfully installed OpenFaaS on Clear Linux Latest and deployed a sample function. You are now ready to build and deploy your own functions using OpenFaaS.
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!
