Nulecule Library

This library contains a set of working examples of composite container applications. The applications are specified using the Nulecule Specification. This specification allows for reusable components and defines a full multi-container application. You may use the applications for reference or, in some cases, deployment.

These examples are all intended to be used with atomicapp. There is a thorough getting started guide available.

Index

• apache-centos7-atomicapp:
  • A centos/apache container similar to the “helloapache” example
• etherpad-centos7-atomicapp:
  • This is a multi-container application that uses both Etherpad and MariaDB
• flask-redis-centos7-atomicapp:
  • A 2-tier application based on Flask and Redis
• gitlab-centos7-atomicapp:
  • A 3-tier application based on Redis, PostgreSQL and Gitlab
• gocounter-scratch-atomicapp:
  • A stand-alone Go application that displays a counter for each web visit
• helloapache:
  • A helloworld example using the centos/apache container
• mariadb-centos7-atomicapp:
  • A single container application built on the centos/mariadb image
• mariadb-fedora-atomicapp:
  • A single container application built on the fedora/mariadb image
• mongodb-centos7-atomicapp:
  • A single container application built on the centos/mongodb-26-centos7 image
• postgresql-centos7-atomicapp:
  • It's a single container application based on the centos/postgresql image
• redis-centos7-atomicapp:
  • A Redis sample application, in which Redis master and slave components are packaged as an Atomic App
• skydns-atomicapp:
  • Deploys SkyDNS on the respective Kubernetes cluster
• wordpress-centos7-atomicapp:
  • This is a Wordpress AtomicApp based on the Nulecule specification.
  • It will reuse the MariaDB AtomicApp to provide Kubernetes, OpenShift3 and Docker based Wordpress to you

Library format

Files:

Please only include the /artifact directory and the Nulecule, Dockerfile and README.md files in your application.

For example projectatomic/helloapache, only includes the following files:

artifacts
??? docker
?   ??? hello-apache-pod_run
??? kubernetes
?   ??? hello-apache-pod.json
Dockerfile
Nulecule
README.md

The README.md file should contain the following three sections:

1. Description: What the application does
2. Deployment: How to deploy the application using the atomic or atomicapp CLIs
3. Interaction: How to access/use the application after deployment

Generating the index.yaml for atomicapp index list commands

In order to generate a Docker-compatible image for an Atomic App library index. Use the following steps:

icapp index generate .
er build -t $USER/index .
