What does this PR do?
This PR adds a new module for the Grafana LGTM docker container, which contains a single container to collect logs, traces and metrics thanks to an Otel Collector, Tempo, Loki and Prometheus, all into the single container.
The module exposes methods to get the endpoints for all the services in the format
<host>:<port>, so please configure your clients accordingly (e.g. adding the http schema if/when needed).The module also exposes an optional configuration for the admin credentials, in case you need to update the default
admin/admincredentials, that the system forces you to update for first time. Passing credentials makes you access the system without updating the password.The testable example code was taken from https://github.com/grafana/docker-otel-lgtm/tree/main/examples/go, which is also used in the otel go sdk: https://opentelemetry.io/docs/languages/go/getting-started/
Why is it important?
With this module, it's super helpful to verify your observability story is able to send Otel data to an otel collector.
