Orchest is an open-source CI/CD pipeline orchestration tool that helps you automate the deployment of your applications, infrastructure, and configuration changes. In this tutorial, you will learn how to install Orchest on Fedora CoreOS latest version.
Before installing any new software, it is essential to update the system to the latest version.
sudo rpm-ostree update
Orchest requires Docker to be installed on the system. Run the following command to install Docker:
sudo rpm-ostree install docker
Check the Docker version to ensure that it is installed correctly:
sudo docker --version
You should see the output similar to the following:
Docker version 20.10.7, build f0df350
To install Orchest on Fedora CoreOS latest version, first, download the binary files:
sudo curl -sSL https://github.com/orchest/orchest/releases/latest/download/orchest-linux-amd64 -o /usr/local/bin/orchest
Make the Orchest binary executable:
sudo chmod +x /usr/local/bin/orchest
Verify that Orchest is installed correctly:
orchest version
You should see the output similar to the following:
Version: 1.1.0
Commit: 2c12f4248342f802b9e9088a6ccb597e6d16a243
Create a new project directory and navigate to it:
mkdir orchest-demo
cd orchest-demo
Create a new Orchest configuration file:
nano orchest.yaml
Copy and paste the following configuration into the file:
version: "1.0"
services:
app:
build:
context: .
dockerfile: Dockerfile
image:
repo: my-orchest-app
tag: latest
deploy:
replicas: 2
template:
resources:
limits:
cpu: 0.5
memory: 256M
Save and close the file.
Create a new Dockerfile:
nano Dockerfile
Copy and paste the following Dockerfile content:
FROM python:3
WORKDIR /usr/src/app
COPY requirements.txt ./
RUN pip install --no-cache-dir -r requirements.txt
COPY . .
CMD ["python", "app.py"]
Save and close the file.
Create a new app.py file:
nano app.py
Copy and paste the following code in the file:
from flask import Flask
app = Flask(__name__)
@app.route("/")
def hello():
return "Hello, World!"
if __name__ == "__main__":
app.run(host="0.0.0.0", debug=True)
Save and close the file.
Build the Docker image:
sudo docker build -t my-orchest-app:latest .
Initialize the Orchest project:
orchest init
Start the Orchest pipeline:
orchest up
Congratulations! You have successfully installed Orchest on Fedora CoreOS and created a simple deployment pipeline. You can now extend this pipeline to your applications and infrastructure seamlessly.
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!
