Building an Application with a RabbitMQ Acorn Service – Part 2
In the previous part, we built an Acorn Service that exposes an instance of RabbitMQ. In the final part, we will build two Acorns - a publisher that periodically publishes messages to the topic and a subscriber that reads from the same...
Sailing Towards Standardization: Open Container Initiative (OCI) Explained
Being a software developer in the 21st century is a boon with so many tools to assist us. From AI-assisted code editors to automated build and deploy tools, life is much simpler. Back in the day, developers built & tested applications...
What is Acorn?
Acorn is a containerized
application packaging framework that simplifies deployment on Kubernetes
-
Developers write Acornfiles to define how to build and run an application.
-
Acorn images are built from the Acornfile and then pushed to any OCI-compatible registry.
-
An Acorn image contains one or more Docker images, configuration files, and deployment specifications.
-
Acorn images can run on any Kubernetes cluster.
-
All of this can be utilized through a simple CLI modeled after Docker.
Introducing Acorn
Why Acorn?
Kubernetes has provided an incredibly powerful engine for running containers, however, the level of complexity it introduces can be daunting for many teams, often creating disconnects between development and operations.
Acorn simplifies app deployment on Kubernetes by introducing a standardized application artifact that runs consistently across dev, test, and production environments.
Having a consistent artifact simplifies Kubernetes operations, and improves application security and reliability.
How Acorn Works
Select any target
Kubernetes cluster
Download and Install Acorn
brew install acorn-io/cli/acorn
acorn init
Create an Acornfile
for the application
echo 'containers: {
nginx: {
image: "nginx"
ports: publish: "80/http"
files: {
"/usr/share/nginx/html/index.html": "<h1>My first Acorn!</h1>"
}
}
}' >Acornfile
Build and push the Acorn image
acorn build -t ghcr.io/user/web .
acorn push ghcr.io/user/web
Deploy the Acorn image to Kubernetes
acorn run --name my-app ghcr.io/user/web
acorn apps my-app
acorn ps
NAME IMAGE HEALTHY UP-TO-DATE CREATED ENDPOINTS MESSAGE
