Description

Some examples of this repository are either not working anymore or are out-of-date. I've been experiencing issues with exporters.logging.verbosity key which has been added recently but isn't working in few examples (see slack discussion).

I've made a tour of the examples to check whether they are out-of-date or not working anymore, results are in #Actual Result.

Steps to Reproduce

For not working examples:

1. Be at the root of the repository
2. Run docker compose -f examples/${EXAMPLE_NAME}/docker-compose.yml

To check whether it is up-to-date or not (reading Dockerfile / docker-compose.yml works too):

1. Be at the root of the repository
2. Update the example configuration by adding the following exporter (this piece of config is recent enough to check if images are up to date):

exporters:
    logging:
        verbosity: detailed

3. Run docker compose up -f examples/${EXAMPLE_NAME}/docker-compose.yml

Expected Result

All examples should be working and up-to-date.

Actual Result

Example name	Is working	Is up-to-date
couchbase	❌	❌
demo	✅	❌
kubernetes	Unknown	Unknown
nomad	Unknown	Unknown
tracegen	❌	✅
tracing	✅	✅

There is no input for kubernetes and nomad, new inputs for them are welcomed!

Couchbase error

$ opentelemetry-collector-contrib/ docker compose up -f examples/couchbase/docker-compose.yml
1 error(s) decoding:

* 'Deploy.Resources.Limits.cpus' expected type 'string', got unconvertible type 'float64', value: '0.5'

Tracegen error

$ opentelemetry-collector-contrib/examples/tracegen docker compose up
unable to prepare context: path "../../tracegen" not found

Demo out-of-date

It is running image otel/opentelemetry-collector-contrib-dev:latest which hasn't been updated for a long time, it should be updated or using Dockerfile from tracing example.

Can I work on this issue, getting the demo example up to date?

It's yours! @jackycsl

I shouldn't have linked this since I assume there will be other PRs needed for the rest of examples. Reopening...
