oslo

CLI tool for the OpenSLO spec. For more information also check the website: openslo.com.

Prerequisites

• Go

Installation

Go install

go install github.com/OpenSLO/oslo/cmd/oslo@latest

From source

1. Checkout this repository
2. From the root of the project, run make install. This will build and install the binary into your GOPATH

Homebrew

brew install openslo/openslo/oslo

From Docker

1. docker run -v "$(pwd):/manifests" ghcr.io/openslo/oslo:latest <command> /manifests/<file>.yaml

For example, if you had an OpenSLO spec file in the current directory called myservice.yaml, and you wanted to validate it, the full command would be:

# docker run -v "$(pwd):/manifests" ghcr.io/openslo/oslo:latest validate /manifests/myservice.yaml
Valid!

Usage

Validate

oslo validate will validate the provided OpenSLO YAML document

Convert

oslo convert will convert the given OpenSLO YAML document to the provided format.

example:

oslo convert -f file1.yaml -f file2.yaml -o nobl9

That will take the provided yaml files, convert them to Nobl9 formatted config format, and output to stdout.

NOTE: Currently only Nobl9 is supported for output. Additionally, deeply nested metric sources are not supported. For metric sources that might have a deeply nested structure, we support a flattened structure, e.g.

metricSource:
  type: Instana
  spec:
    infrastructure.query: "myQuery"
    infrastructure.metricRetrievalMethod: "myMetricRetrievalMethod"

Testing

To test out the features of oslo, from the root of the project run oslo validate test/valid-service.yaml That will validate against a valid yaml file. There are other files in that directory to test out the functionality of oslo
