Attempt to fix value not found: discovery.ip when using docker discovery

[das-peter]

Getting error : level=error msg="can't start integration" component=integrations.runner.Runner env=dev environment=dev error="value not found: discovery.ip" Assume it's caused by not setting default discovery.ip when no ports are exposed.

Hi @das-peter, can you please include an example of an integration config to reproduce the error?

[das-peter]

@josemore thanks for the feedback and sorry for the noise. Unfortunately I can't spent any more time on it and just went with hard coded values.
So please feel free to disregard - won't close it just now since I'll add some info I got.

However, I can provide a quick example of how it was run:
Infrastructure contain in the compose setup:

  newrelic-infra:
    container_name: ${COMPOSE_PROJECT_NAME}-newrelic-infra
    image: ************/newrelic-infrastructure
    cap_add:
      - SYS_PTRACE
    environment:
      NEWRELIC_KEY: ${NEWRELIC_KEY}
      NRIA_LICENSE_KEY: ${NEWRELIC_KEY}
      COMPOSE_PROJECT_NAME: ${COMPOSE_PROJECT_NAME}
      ENVIRONMENT: ${ENVIRONMENT}
      NRI_MYSQL_USER: "newrelic"
      NRI_MYSQL_USER_PASSWORD: "*******************"
      # Disabled by default but can be handy for debugging.
      NRIA_ENABLE_PROCESS_METRICS: "true"
    # We don't expose all container ports - hence we stay in the container
    # networks. It's more important to collect container info than host network
    # metrics for the moment.
    #network_mode: host
    pid: host
    privileged: true
    volumes:
      - "/:/host:ro"
      - "/var/run/docker.sock:/var/run/docker.sock"
    restart: unless-stopped

Custom image build

FROM newrelic/infrastructure:latest

# Repo: https://download.newrelic.com/infrastructure_agent/binaries/linux/amd64/
# Get all the clients we need.
# DON'T add varnish because it needs version specific varnish binaries and
# volume mappings in order to run. Dedicated image is used.
RUN cd /tmp/ \
    && wget https://download.newrelic.com/infrastructure_agent/binaries/linux/amd64/nri-docker_linux_1.8.27_amd64.tar.gz \
    && tar -xf nri-docker_linux_* -C / \
    && wget https://download.newrelic.com/infrastructure_agent/binaries/linux/amd64/nri-redis_linux_1.11.2_amd64.tar.gz \
    && tar -xf nri-redis_linux_* -C / \
    ....
    

Integration config example:

integration_name: com.newrelic.elasticsearch

# Use autodiscovery within our docker stack.
# Autodiscovery is fucked - always leads to:
# level=error msg="can't start integration" component=integrations.runner.Runner env=dev environment=dev error="value not found: discovery.ip" integration_name=nri-flex project=dobi role=php-fpm runner_uid=358170999e
# Even without using discovery.ip anywhere.
discovery:
  docker:
    match:
      image: /elasticsearch/
integrations:
  - name: nri-elasticsearch
    command: all
    arguments:
      cluster_environment: {{ENVIRONMENT}}
      HOSTNAME: ${discovery.ip}
      LOCAL_HOSTNAME:  ${discovery.ip}
    env:
      METRICS: true
      CLUSTER_ENVIRONMENT: {{ENVIRONMENT}}
      HOSTNAME:  ${discovery.ip}
      LOCAL_HOSTNAME: ${discovery.ip}
    labels:
      role: elasticsearch
      project: {{COMPOSE_PROJECT_NAME}}
      environment: {{ENVIRONMENT}}
      env: {{ENVIRONMENT}}
