How to escape single quote in ARM template

Question

Given the following resource in an AzureRM template, how would one encode the single quote in the commandToExecute part?

Answer 1

I've worked around this with a variable:

"variables": {
    "singleQuote": "'",
},
...
"settings": {
    "fileUris": [],
    "commandToExecute": "[concat('/bin/bash -c ', variables('singleQuote'), 'echo \"export DOCKER_HOST=:2375\" >> /home/', parameters('adminUsername') ,'/.profile', variables('singleQuote'))]",
}

It isn't elegant but it works.
