Keptn Service for Dynatrace Monaco

This is a Sandbox Keptn Services that enables calling the Dynatrace Monaco (Monitoring as Code) toolset for individual Keptn Events

Installation

The monaco-service can be installed as a part of Keptn's uniform.

Deploy in your Kubernetes cluster

To deploy the current version of the monaco-service in your Keptn Kubernetes cluster, apply the deploy/service.yaml file:

kubectl apply -f deploy/service.yaml

This should install the monaco-service together with a Keptn distributor into the keptn namespace, which you can verify using

kubectl -n keptn get deployment monaco-service -o wide
kubectl -n keptn get pods -l run=monaco-service

Up- or Downgrading

Adapt and use the following command in case you want to up- or downgrade your installed version (specified by the $VERSION placeholder):

kubectl -n keptn set image deployment/monaco-service monaco-service=keptnsandbox/monaco-service:$VERSION --record

Uninstall

To delete a deployed monaco-service, use the file deploy/*.yaml files from this repository and delete the Kubernetes resources:

kubectl delete -f deploy/service.yaml

Usage

The goal of the monaco-service is to allow the user to trigger Dynatrace Monaco as part of their keptn-driven releases. For more information about how Dynatrace Monaco works, please check the git repository README: https://github.com/dynatrace-oss/dynatrace-monitoring-as-code

It needs the following configured:

Kubernetes secret for Dynatrace Environment

A Kubernetes secret containing the values DT_TENANT and DT_API_TOKEN is needed. The DT_API_TOKEN should have the permission to read and write configuration
The monaco-service looks by default for the following secrets: dynatrace, dynatrace-credentials and dynatrace-credentials-$PROJECT. If a different secret name can be configured by adding a resource dynatrace\monaco.conf.yaml. In this file you can specificy in the variable dtCreds the name of a secret containing the info.

Option 1: Monaco projects folders

You can upload your monaco configuration on the service, stage or project level. If you do you have to follow the monaco folder structure starting with projects under the dynatrace subfolder. The folder structure should therefore be the following:

+-- dynatrace // this is where the dynatrace related config goes in general
|   +-- projects // this folder name needs to be used
|       +-- projectName (this can be customized)
|           +-- configuration1 (check monaco documentation for the possible options)
|               +-  json and yaml files (check monaco documentation for the possible options)
|       +-- projectN
|           +-- json and yaml files

You can add these files to Keptn by using

keptn add-resource --project=PROJECTNAME --service=SERVICENAME --stage=STAGENAME --resource=auto-tag/tagging.json --resourceUri=dynatrace/projects/keptnservice/auto-tag/tagging.json
keptn add-resource --project=PROJECTNAME --service=SERVICENAME --stage=STAGENAME --resource=auto-tag/tagging.yaml --resourceUri=dynatrace/projects/keptnservice/auto-tag/tagging.yaml

stage and service are optional. The monaco-service will automatically download all files under the dynatrace/projects directory first on the service level, then on stage level and last on project level.

Option 2: A ZIP archive containing the projects

Now - this is the same as Option 1 - but - instead of having each file separate in Keptn's configuration repo you can also just zip it up and upload the zipped projects directoy to the dynatrace subfolder The folder structure should be the following:

+-- projects // this folder name needs to be used
|   +-- projectName (this can be customized)
|       +-- configuration1 (check monaco documentation for the possible options)
|           +-  json and yaml files (check monaco documentation for the possible options)
|   +-- projectN
|       +-- json and yaml files

Note: the archive has to be of type zip. Using the zip command on linux, it can be created as follows:

zip -r monaco.zip directory_name

You can add the file to Keptn by using

keptn add-resource --project=PROJECTNAME --service=SERVICENAME --stage=STAGENAME --resource=monaco.zip --resourceUri=dynatrace/monaco.zip

stage and service are optional. The monaco-service will automatically look for this file first on the service level, then on stage level and last on project level.

Specifying which monaco projects to process

If not specified, the monaco-service looks for a monaco project with the name of the keptn project. So if your keptn project name is sockshop, then you would need the following structure in the monaco.zip file:

+-- projects 
|   +-- sockshop 
|       +-- auto-tag (an example) 
|           +-  json and yaml files

If you want to overwrite that behaviour, it is possible to specify that in the dynatrace\monaco.conf.yaml file by adding them as follows:

projects:
  - monaco
  - sockshop
  - infrastructure

All the projects that you want to process can be added. So for the above, you would need the following structure:

+-- projects 
|   +-- infrastructure 
|       +-- synthetic-location 
|           +-  json and yaml files
|   +-- monaco 
|       +-- auto-tag
|           +-  json and yaml files
|   +-- sockshop 
|       +-- management-zone 
|           +-  json and yaml files

Using Keptn metadata inside monaco files

The monaco-service automatically maps the following Keptn information as environment variables:

Keptn project name as env var KEPTN_PROJECT
Keptn stage name as env var KEPTN_STAGE
Keptn service name as env var KEPTN_SERVICE

They can then be used inside monaco files as follows: {{ Env.KEPTN_PROJECT }} For an example, please check tagging.json

Development

This is an open source project, so I welcome any contributions to make it even better!

Where to start

If you don't care about the details, your first entrypoint is eventhandlers.go. Within this file you can add implementation for pre-defined Keptn Cloud events.

To better understand Keptn CloudEvents, please look at the Keptn Spec.

If you want to get more insights, please look into main.go, deploy/service.yaml, consult the Keptn docs as well as existing Keptn Core and Keptn Contrib services.

Build yourself

Build the binary: go build -ldflags '-linkmode=external' -v -o monaco-service
Run tests: go test -race -v ./...
Build the docker image: docker build . -t keptnsandbox/monaco-service:dev (Note: Ensure that you use the correct DockerHub account/organization)
Run the docker image locally: docker run --rm -it -p 8080:8080 keptnsandbox/monaco-service:dev
Push the docker image to DockerHub: docker push keptnsandbox/monaco-service:dev (Note: Ensure that you use the correct DockerHub account/organization)
Deploy the service using kubectl: kubectl apply -f deploy/
Delete/undeploy the service using kubectl: kubectl delete -f deploy/
Watch the deployment using kubectl: kubectl -n keptn get deployment monaco-service -o wide
Get logs using kubectl: kubectl -n keptn logs deployment/monaco-service -f
Watch the deployed pods using kubectl: kubectl -n keptn get pods -l run=monaco-service
Deploy the service using Skaffold: skaffold run --default-repo=your-docker-registry --tail (Note: Replace your-docker-registry with your DockerHub username; also make sure to adapt the image name in skaffold.yaml)

Testing Cloud Events

We have dummy cloud-events in the form of RFC 2616 requests in the test-events/ directory. These can be easily executed using third party plugins such as the Huachao Mao REST Client in VS Code.
