slok / service-level-operator-sloth-migrator

Simple script to migrate CRs from service-level-operator to sloth

service-level-operator-sloth-migrator

A simple CLI that will migrate service-level-operator CRs to sloth CRs.

Example: go run ./ --slos ./example/awesome.yaml --out /tmp && sloth generate -i /tmp/_gen__awesome-service.yaml

Getting started

These are the steps:

• Get service-level-operator SLOs from Kubernetes using kubectl.
• Use this CLI to migrate them.
• Apply new sloth CRs using sloth CLI or Kubernetes controller mode.

Lets see an example:

# Get service-level-operator SLOs.
kubect get servicelevels --all-namespaces -o yaml > ./slos.yaml

# Migrate to sloth.
mkdir ./sloth-specs
go run ./  --slos ./slos.yaml --out ./sloth-specs

# Check sloth specs by generating prometheus-operator rules CRs.
mkdir ./prom-specs
for f in ./sloth-specs/*; do sloth generate -i ${f} -o ./prom-specs/$(basename ${f}); done

Advanced options

• --ignore-disable: If used, it will not migrate the SLOs that have disable: true.
