Helm (Kubernetes) plugin for drone.io

This plugin allows to deploy a Helm chart into a Kubernetes cluster.

For example, this configuration will deploy Jenkins using the stable/jenkins chart

    pipeline:
        deploy:
            image: ipedrazas/drone-helm
            command: 
                - "install"
                - "--name"
                - "my-release"
                - "stable/jenkins"
                - "--debug", 
                - "--dry-run"
            api_server: "http://my_api_server"
            kubernetes_token: "secret token"
            skip_tls_verify: "true"

If you don't know where to get a token from, you can execute the following command:

    kubectl exec POD_NAME -- cat /var/run/secrets/kubernetes.io/serviceaccount/token

For example, in a cluster where there's a pod called nginx-1212390922-fdz1x we coudl do:

    kubectl exec nginx-1212390922-fdz1x -- cat /var/run/secrets/kubernetes.io/serviceaccount/token

To test the plugin, you can run minikube and just run the docker image as follows:

    docker run -i ipedrazas/drone-helm /bin/drone-helm <<EOF
    {
        
        "vargs": {
            "command": ["version"],
            "api_server":"https://192.168.64.5:8443",
            "kubernetes_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3BhY2UiOiJkZWZhdWx0Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZWNyZXQubmFtZSI6ImRlZmF1bHQtdG9rZW4tcnloeTciLCJrdWJlcm5ldGVzLmlvL3NlcnZpY2VhY2NvdW50L3NlcnZpY2UtYWNjb3VudC5uYW1lIjoiZGVmYXVsdCIsImt1YmVybmV0ZXMuaW8vc2VydmljZWFjY291bnQvc2VydmljZS1hY2NvdW50LnVpZCI6IjU5ZWQzYjM1LWI0MmUtMTFlNi05ZDI3LTFlZGZkMzA0MTNhNiIsInN1YiI6InN5c3RlbTpzZXJ2aWNlYWNjb3VudDpkZWZhdWx0OmRlZmF1bHQifQ.aGX19xTFJdxC6d5hObKUms9Kaq0wR8fMypXTnsfjC6XjiA3_QWX9LJdRFl6wvZTRoIAjuOhAJKNAKhLQ3sK0aKrddNxn2is-HCb88BXma3BrHWOtkwajvZ1dyAhZOe2fY1I77t_mrbvTMqJ4udsom6roHf-KL8j29DJWsV0nFh6VKyvqN8f7FsNG3WuH3SFZX_LfcE0HfZxrDaVEi-CkDo0sGCqIefDk2sn4IQD6b1Ng-grJWSN-YtrcDDduEKlUHPSRMmMtWa3-Q61-yQqlyqATGbxC3UwqwaLfjCrTkg1Uikv4jWDP3-eNmuQCqG9PHKulA1riTFAgxbr09zoYxg",

            "skip_tls_verify": "true"
        }
    }
    EOF

This will display the helm version in the plugin and the helm version in the cluster. The following example will test the previous .drone.yml configuration:

    docker run -i ipedrazas/drone-helm <<EOF
    {
        
        "vargs": {
            "command": ["install", "--name", "my-release", "stable/jenkins", "--debug", "--dry-run"],
            "api_server":"https://192.168.64.5:8443",
            "kubernetes_token": "eyJhbGciOiJSUzI1NiIsInR5cCI6IkpXVCJ9.eyJpc3MiOiJrdWJlcm5ldGVzL3NlcnZpY2VhY2NvdW50Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9uYW1lc3BhY2UiOiJkZWZhdWx0Iiwia3ViZXJuZXRlcy5pby9zZXJ2aWNlYWNjb3VudC9zZWNyZXQubmFtZSI6ImRlZmF1bHQtdG9rZW4tcnloeTciLCJrdWJlcm5ldGVzLmlvL3NlcnZpY2VhY2NvdW50L3NlcnZpY2UtYWNjb3VudC5uYW1lIjoiZGVmYXVsdCIsImt1YmVybmV0ZXMuaW8vc2VydmljZWFjY291bnQvc2VydmljZS1hY2NvdW50LnVpZCI6IjU5ZWQzYjM1LWI0MmUtMTFlNi05ZDI3LTFlZGZkMzA0MTNhNiIsInN1YiI6InN5c3RlbTpzZXJ2aWNlYWNjb3VudDpkZWZhdWx0OmRlZmF1bHQifQ.aGX19xTFJdxC6d5hObKUms9Kaq0wR8fMypXTnsfjC6XjiA3_QWX9LJdRFl6wvZTRoIAjuOhAJKNAKhLQ3sK0aKrddNxn2is-HCb88BXma3BrHWOtkwajvZ1dyAhZOe2fY1I77t_mrbvTMqJ4udsom6roHf-KL8j29DJWsV0nFh6VKyvqN8f7FsNG3WuH3SFZX_LfcE0HfZxrDaVEi-CkDo0sGCqIefDk2sn4IQD6b1Ng-grJWSN-YtrcDDduEKlUHPSRMmMtWa3-Q61-yQqlyqATGbxC3UwqwaLfjCrTkg1Uikv4jWDP3-eNmuQCqG9PHKulA1riTFAgxbr09zoYxg",
