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
