Just finished writing my first ARM template that can deploy a set of VMs, where in one VM has an Apache and php installed with a sample website, and another VM with an installation of Neo4j which is accessible only to the first VM on a private port. The Sample website in the Apache node can echo out a message if it could get connected successfully.
The repo is yet to be merged with the Azure repo, but for now one can find it here https://github.com/brijrajsingh/azure-quickstart-templates/tree/master/101-lap-neo4j-ubuntu.
Lets discuss the construct of our ARM template, This is the folder structure of our ARM template
ARM Template folder structure
azuredeploy.json, azuredeploy.parameters.json, metadata.json and README.md are mandatory file for any template to be a valid ARM template, you can find the rules in the github repo here https://github.com/Azure/azure-quickstart-templates#readmemd.
The installation of Apache, PHP and code to check connectivity as well as installation of Neo4J is done by the custom script extensions.
install-lap.sh – is the script to
- Install Apache
- Install php5
- Install Composer – Globally
- Write a Info.php file – to emit phpinfo()
- Write a file neo4jtest.php – which echo out ‘connected successfully’ if it can connect to the Neo4J VM on a static IP – 10.0.0.10
install-neo4j.sh – is the script to
- Add Neo4J to the packages source list
- Update apt-get
- Install Java 8 (Silently) – Neo4J needs JDK or JRE – as in Neo4J(J is Java)
- Install Neo4j
- Enable remote connectivity to Neo4J and restart Neo4j
