gcloud CLI Mixin for Porter

This is a mixin for Porter that provides the gcloud CLI.

Mixin Syntax

See the gcloud CLI Command Reference for the supported commands

gcloud:
  description: "Description of the command"
  groups: GROUP
  command: COMMAND
  arguments:
  - arg1
  - arg2
  flags:
    FLAGNAME: FLAGVALUE
    REPEATED_FLAG:
    - FLAGVALUE1
    - FLAGVALUE2
  suppress-output: false
  outputs:
    - name: NAME
      jsonPath: JSONPATH

You can also specify a list of groups:

gcloud:
  description: "Description of the command"
  groups:
  - GROUP 1
  - GROUP 2
  command: COMMAND

Suppress Output

The suppress-output field controls whether output from the mixin should be prevented from printing to the console. By default this value is false, using Porter's default behavior of hiding known sensitive values. When suppress-output: true all output from the mixin (stderr and stdout) are hidden.

Step outputs (below) are still collected when output is suppressed. This allows you to prevent sensitive data from being exposed while still collecting it from a command and using it in your bundle.

Outputs

The mixin supports jsonpath outputs.

JSON Path

The jsonPath output treats stdout like a json document and applies the expression, saving the result to the output.

outputs:
- name: NAME
  jsonPath: JSONPATH

For example, if the jsonPath expression was $[*].id and the command sent the following to stdout:

[
  {
    "id": "1085517466897181794",
    "name": "my-vm"
  }
]

Then then output would have the following contents:

["1085517466897181794"]
