Logstash Docker on GCP Cloud Run: Failed to find a usable hardware address from the network interfaces

Elastic Stack Logstash
1

Hi all,

I'm coupling PubSub with a Logstash custom image running on GCP Cloud Run, this image will output messages to an Elastic Cloud configuration.

I'm currently hitting some errors on Cloud Run which I can't seem to fix related to:
Failed to find a usable hardware address from the network interfaces

The Dockerfile looks like this:

    FROM docker.elastic.co/logstash/logstash:7.9.0
    ADD pipeline/ /usr/share/logstash/pipeline/
    ADD config/ /usr/share/logstash/config/
    RUN bin/logstash-plugin install logstash-input-google_pubsub
    RUN chown -R logstash:root /usr/share/logstash/config 
    RUN ls -al /usr/share/logstash/config/
    EXPOSE 5000

The config file looks like this:

    input {

        google_pubsub {

            project_id => "${PROJECT_ID}"
            topic => "${PUBSUB_TOPIC}"
            subscription => "logstash-sub"
            create_subscription => false
        }
    }
    output {
      elasticsearch {
        hosts => "${HOSTS}"
        user => "${USERNAME}" 
        password => "${PASSWORD}"  
        index => "${INDEX}"
        }
      stdout {
      }
    }

If anyone helping with this requires any other data please let me know. I'm new to handling Logstash.

A little extra info on what I see happening:
The Container spins up fine, sets up a pipeline that already fetches the input from Pub/Sub, then after about a minute the aforementioned error comes up and I get a [logstash.runner ] SIGTERM received. Shutting down. message before the container deployment fails.
