Simple tool for converting strings to valid Azure Resource Manager template strings

What is it?

Simple tool for converting strings to valid Azure Resource Manager template strings.

It useful for passing a lot of data to VM by custom data in ARM templates.

For example you need pass some data to VM. In ARM template it can looks like:

{
...
"customData": "[base64(concat('#!/bin/sh\n\ncat > /home/ec2-user/config.json << CONFIG\n{\n   \"domain\": \"',reference(parameters('frontIpName')).dnsSettings.fqdn,'\",\n    \"sslKey\": \"',parameters('domainSslKey'),'\"\n}\nCONFIG\n\nsh /home/ec2-user/init.sh\n'))]",
...
}

It is hell. And it is not a lot of data.

This tool converts next readable text to string above:

#!/bin/sh

cat > /home/ec2-user/config.json << CONFIG
{
	"domain": "${reference(parameters('frontIpName')).dnsSettings.fqdn}",
	"sslKey": "${parameters('domainSslKey')}"
}
CONFIG

sh /home/ec2-user/init.sh
