Configuration YAML structure

​ This guide explains the structure of a YAML config file. ​

Config YAML structure

​ Every configuration needs a YAML file containing required and optional content. ​ A minimum viable config should look like this: ​

config:
    - {config name} : "{path of config json template}"
​
{config name}:
    - name: "{a unique name}"

​ Example: in projects/infrastructure/alerting-profile/profiles.yaml ​

config:
  - profile: "projects/infrastructure/alerting-profile/profile.json"
​
profile:
  - name: "profile-name"
[...]

​ Every config needs to provide a name for unique identification. Omitting the name variable or using a duplicate name causes a validation / deployment error. ​ Any defined {config name} represents a variable that can then be used in a JSON template, and will be resolved and inserted into the config before deploying to Dynatrace. ​ Example: projects/infrastructure/alerting-profile/profiles.yaml defines a name, which is then used in projects/infrastructure/alerting-profile/profile.json as {{.name}}. ​

[...]
profile:
  - name: "EXAMPLE Infrastructure"
[...]

​

Skip configuration deployment

​ To skip the deployment of a configuration, use the predefined skipDeployment parameter. ​

my-config:
  - name: "My config"
  - skipDeployment: "true"

If you wan to enable it by default, but skip for environment or group, do the following:

my-config:
  - name: "My config"
  - skipDeployment: "true"
​
my-config.development:
  - skipDeployment: "false"

If you want to disable it by default and enable only for environment or group:

my-config:
  - name: "My config"
  - skipDeployment: "false"
​
my-config.environment:
  - skipDeployment: "true"

​

Specific configuration per environment or group

​ Configurations can be overwritten or extended:

• per environment, by adding .{Environment} configurations
• per group, by adding .{GROUP} configurations ​ projects/infrastructure/notification/notifications.yaml defines different recipients for email notifications for each environment via ​

email:
    [...]
​
email.group:
    [...]
​
email.environment1:
    [...]
​
email.environment2:
    [...]
​
email.environment3:
    [...]

​ Anything in the base email configuration is still applied, unless it's re-defined in the .{GROUP} or .{Environment} config. ​

⚠️ If both environment and group configurations are defined, then environment is preferred over the group configuration. ​

Referencing other configurations

​ In many cases, one auto-deployed Dynatrace configuration depends on another one. E.g., where most configurations depend on the management-zone defined in projects/infrastructure/management-zone ​ The tool allows your configuration to reference either the name or id of the Dynatrace object of another configuration created on the cluster. ​ To reference these, the dependent config yaml can configure a variable of the format ​

{var} : "{name of the referenced configuration}.[id|name]"

​ e.g. projects/project-name/dashboard/dashboard.yaml references the management-zone defined by /projects/infrastructure/management-zone/zone.json via

  - managementZoneId: "projects/infrastructure/management-zone/zone.id"

​

Referencing other JSON templates

JSON templates are usually defined inside of a project configuration and then referenced in the same project: ​ testproject/auto-tag/auto-tag.yaml:

config:
  - application-tagging-multiproject: "application-tagging.json"
​
application-tagging-multiproject:
  - name: "Test Application Multiproject"

​ In this example, application-tagging.json is located in the auto-tag folder of the same project and the path to it can be defined relative to auto-tag.yaml file. But, what if you would like to reuse one template defined outside of this project? In this case, you need to define the full path of a json template: ​ testproject/auto-tag/auto-tag.yaml:

config:
  - application-tagging-multiproject: "/path/to/project/auto-tag/application-tagging.json"
​
application-tagging-multiproject:
  - name: "Test Application Multiproject"

This would save us from content duplication and redefining the same templates over and over again. ​ Of course, it is also possible to reuse one template multiple times within one or different YAML file(s): testproject/auto-tag/auto-tag.yaml:

config:
  - application-tagging-multiproject: "/path/to/project/auto-tag/application-tagging.json"
  - application-tagging-tesproject: "/path/to/project/auto-tag/application-tagging.json"
  - application-tagging-otherproject: "/path/to/project/auto-tag/application-tagging.json"
​
application-tagging-multiproject:
  - name: "Test Application Multiproject"
  - param: "Multiproject parameter"
​
application-tagging-tesproject:
  - name: "Test Application Tesproject"
  - param: "Tesproject parameter"
​
application-tagging-otherproject:
  - name: "Test Application Otherproject"
  - param: "Otherproject parameter"

​

Templating of environment variables

​ In addition to the templating of JSON files, where you need to specify the values in the corresponding YAML files, its also possible to resolve environment variables. This can be done in any JSON or YAML file using this syntax: {{.Env.ENV_VAR}}. ​ E.g., to resolve the URL of an environment, use the following snippet: ​

development:
    - name: "Dev"
    - env-url: "{{ .Env.DEV_URL }}"
    - env-token-name: "DEV_TOKEN_ENV_VAR"

​ An environment variable can also be resolved directly in the JSON. See the following example which sets the value of an alerting profile from the env var ALERTING_PROFILE_VALUE. ​

{
  "name": "{{ .name }}",
  "rules": [
    {
      "type": "APPLICATION",
      "enabled": true,
      "valueFormat": null,
      "propagationTypes": [],
      "conditions": [
        {
          "key": {
            "attribute": "WEB_APPLICATION_NAME"
          },
          "comparisonInfo": {
            "type": "STRING",
            "operator": "CONTAINS",
            "value": "{{ .Env.ALERTING_PROFILE_VALUE }}",
            "negate": false,
            "caseSensitive": true
          }
        }
      ]
    }
  ]
}

⚠️ Values you pass into a configuration as environment variables must not contain the = character.
