Unable to start a machine on Exoscale

[vincentbernat]

Hey!

When starting a new host on Exoscale. we get the following error: Unsupported type: []string. This is because the securityGroup configuration parameter should be a string and not an array. In go-machine-service, the generated JSON is incorrect:

        "securityGroup": {
            "type": "array[string]",
            "nullable": true
        },

This should be:

        "securityGroup": {
            "type": "string",
            "nullable": true
        },

I didn't understand how this file is generated. The copy in rancher/machine repository is up-to-date but somehow, when the files are regenerated with scripts/generate, they are still wrong.

The generation code is correct. It correctly interpreted the type []string from this flag exoscale.go#L78. This is a bug in go-machine-service. We are not parsing flags correctly - create.go#L242

Thanks for the pointer. I'll try to fix that then (unless you already have some kind of solution).

Don't worry about it. I'll fix it before the end of the day today. It'll be added to the next release.

@vincentbernat - This PR fixes it - rancher/go-machine-service#69
