Github Action for Instana Release markers

This action creates a new release on your Instana tenant via the Instana Pipeline Feedback capability.

Variables

Set the following variables as secrets for your repository:

INSTANA_BASE: The base url of your tenant (e.g. https://test-example.instana.io)
INSTANA_TOKEN: The API token to create releases at Instana, which must have the Configuration of releases permission. Refer to the Tokens documentation on the Instana website for more information on how to create API tokens.

Inputs

releaseName (required): The name of the release to create
releaseScope (optional): scoping information for the release in terms of Application Perspectives and Services. The file should contain valid JSON object that satisfies jq type == 'object', and it can have as fields applications and services, which respectively have the same structure as in the API documentation for creating releases, e.g.:
```
{
  "applications": [
    { "name": "My Awesome App" },
    { "name": "My Even More Awesome App" }
  ],
  "services": [
    { "name": "Cool service #1" },
    {
      "name": "Cool service #2",
      "scopedTo": {
        "applications": [
          { "name": "My Cool App" }
        ]
      }
    }
  ]
}
```
The JSON snippet above will scope the new release to apply to the entirety of the Application Perspectives My Awesome App and My Even More Awesome App, to the entirely of the Cool service #1 service, and to the Cool service #2 service, but only to what part of Cool service #2 is included in the My Cool App Application Perspective. For more information on Application Perspectives, Services and the scoping, refer to the Application Monitoring documentation.

Note: Release scoping is supported in Instana v190 and above; using release scoping with older versions of Instana will not lead to issues, but the scoping specification will be ignored.

Outputs

id: The id of the newly-created release

Example usage

Without Release Scoping

uses: taimos/github-action-instana-release@%%version%%
with:
  releaseName: 'Deployed version 42'
env:
  INSTANA_BASE: ${{ secrets.INSTANA_BASE }}
  INSTANA_TOKEN: ${{ secrets.INSTANA_TOKEN }}

With Release Scoping

uses: taimos/github-action-instana-release@%%version%%
with:
  releaseName: 'Deployed version 42'
  releaseScope: >
    {
      "services": [
        {
          "name": "spring-webflux",
          "scopedTo": {
            "applications": [{ "name": "All Services" }]
          }
        },
        { "name": "spring-boot" }
      ]
    }
env:
  INSTANA_BASE: ${{ secrets.INSTANA_BASE }}
  INSTANA_TOKEN: ${{ secrets.INSTANA_TOKEN }}

Notice that, to nest a JSON datastructure in YAML without dealing with conversion issues, we are actually using a YAML multiline string by adding > at the beginning of the value for releaseScope. When using YAML multiline string, each line of the string must be indented at least one level deeper than the key. The YAML Multiline is excellent to understand the nuances of multiline in YAML.

Testing

To test a new version of this GitHub Action, copy the test/test-action.yml to .github/workflows. The test can be executed locally with act.

act -s INSTANA_BASE=<<INSTANA_BASE>> -s INSTANA_TOKEN="<<INSTANA_TOKEN>>" [--env version=<<VERSION>>]

The version is optional and will be used to identify the user-agent. If not set dev will used as version.
