libbuildpack-dynatrace

Base Library for Go-based Cloud Foundry Buildpack integrations with Dynatrace.

Summary

The library provides the Hook struct that implements the libbuildpack.Hook interface that it's requested by the CF Buildpacks.

On the buildpacks, you're expected to provide a hook through a init() function where you can register such hook implementation. For example, a simple implementation could be,

import (
    "github.com/cloudfoundry/libbuildpack"
    "github.com/Dynatrace/libbuildpack-dynatrace"
)

func init() {
    libbuildpack.AddHook(dynatrace.NewHook("nodejs", "process"))
}

Configuration

The Hook will look for credentials in the configurations for existing services (which is represented in the runtime as the VCAP_SERVICES environment variable in JSON format.) We look for service names having the 'dynatrace' substring.

We support the following configuration fields,

Key Type Description Required Default
environmentid string The ID for the Dynatrace environment. Yes N/A
apitoken string The API Token for the Dynatrace environment. Yes N/A
apiurl string Overrides the default Dynatrace API URL to connect to. No Default API URL
skiperrors boolean If true, the deployment doesn't fail if the Dynatrace agent download fails. No false
networkzone string If set, agent is configured to choose communication endpoints located at the field's value. No empty
enablefips boolean If true, the FIPS 140-2 mode is enabled No false

For example,

cf create-user-provided-service dynatrace -p '{"environmentid":"...","apitoken":"..."}'

See more at the documentation for cf create-user-provided-service.

We also support standard Dynatrace environment variables.

Requirements

Development

You can download or clone the repository.

You can run tests through,

go test

If you modify/add interfaces, you may need to regenerate the mocks. For this you need gomock:

# To download Gomock
go get github.com/golang/mock/gomock
go install github.com/golang/mock/mockgen

# To generate the mocks
go generate
