[MohdRashid01]

Hi All,

I try to change port number in docker-compose.yml file but its not working it taking default port number only. Here is the docker-compose.yml

 cat docker-compose.yml 
version: '3.2'

services:

  prometheus:
       image: prom/prometheus:latest
#       container_name: monitoring_prometheus
       command:
         - '--config.file=/etc/prometheus/prometheus.yml'

and Here is the prometheus.yml file

cat prometheus.yml 
# my global config

  # scrape_timeout is set to the global default (10s).       
  # Attach these labels to any time series or alerts when communicating with       
  # external systems (federation, remote storage, Alertmanager).       

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.       
rule_files:       
  - "/etc/prometheus/alert.rules"
  - "/etc/prometheus/container.yml"
  - "/etc/prometheus/diskusage.yml"
  # - "first.rules"       
  # - "second.rules"       

# Alerting specifies settings related to the Alertmanager
alerting:
 alertmanagers:
   - static_configs:
     - targets:
       # Alertmanager's default port is 9093
       - alertmanager:9093

# A scrape configuration containing exactly one endpoint to scrape:       
# Here it's Prometheus itself.       
scrape_configs:       

#  - job_name: 'prometheus'
#    static_configs:
#      # the targets listed here must match the service names from the docker-compose file       
#      - targets: ['prometheus:9090']

  - job_name: 'node-exporter'       
    static_configs:       
      # the targets listed here must match the service names from the docker-compose file       
      - targets: ['node-exporter:9100']       

  - job_name: 'cadvisor'       
    static_configs:                       
      # the targets listed here must match the service names from the docker-compose file       
      - targets: ['cadvisor:8080']

Here is the screenshot which u can see port number is showing different in docker container

All the config options are documented on https://github.com/prymitive/karma/blob/main/docs/CONFIGURATION.md Pass --listen.port N or export LISTEN_PORT=N env variable.

karma-alert-dashboard:

image: cloudflare/unsee

   image: lmierzwa/karma:latest
   environment:
     - "export LISTEN_PORT=9094"
     - "ALERTMANAGER_URI=http://alertmanager:9093"
   ports:
     - '9094:9094'
