📋 Step-by-Step Guide

Before You start

• Port 8000 must be open (default port)
• Docker & Docker Compose should be installed (optional)
• The presence of Git and Python3

Getting started

🐳 Deploy with Docker

• clone and enter the repository using the following commands:

  git clone https://github.com/Shayan-Ghani/Container-exporter.git
  cd Container-Exporter

• Deploy the docker-compose file that suits you the best for instance :

# Make the file executable
  chmod +x ./start.sh

# With docker compose v1
  docker-compose -f container-exporter.yml up -d
# Or using v2
  docker compose -f container-exporter.yml up -d
# build from base with Dockerfile
  docker-compose -f container-exporter-local.yml up --build -d

alternatively, run docker-compose -f container-exporter-local.yml up --build -d to build from Dockerfile

🐍 Can't use Docker? Ok then :

# No need if done already
  chmod +x ./start.sh

# Set up virtualenv
  python3 -m venv venv
  source venv/bin/activate
  pip install -U pip

# Install the required python packages
  pip install -r requirements.txt

# start the initializer script.
  ./start.sh &

You can use nohup as well :

nohup ./start.sh -out ./nohup.out

# to stop cxp without docker use this command 
kill -9 <PID>

Replace <PID> with the pid of ./start.sh script.

🚢 Run With A Custom Port:

./start.sh <your custome port> &  
# or 
CONTAINER_EXPORTER_PORT=<your custom port> docker-compose -f container-exporter.yml up -d

Change <your custom port> with a port of your choice and make sure you change the port mapping in docker-compose accordingly.

🔥 Add CXP to Prometheus

• Edit your prometheus.yml file and add the address of container-exporter in scrape_configs:

• Reload or restart your Prometheus server and reach out to http://127.0.0.1:8000/metrics

That is it you are good to go, Enjoy Using CXP! "}"

📊 Grafana Dashboards

Check out dashboards directory for Json files. including CPU & Memory usage + containers status (uptime).

Change Your Prometheus data source uid with the uid of Prometheus data source uid. you can find it this way:

• Reach out to Grafana then enter Home > Administration > Data sources then click on your Prometheus data source.

• the characters after datasources/edit/ are your uid. (e.g datasources/edit/c8e586ac-4262-4aad5-a103-1240ss826424)

• alternatively, use dashboard-gen.sh script to change the dashboards' uid by providing the uid as the first argument of the script. do the following steps:

 cd scripts && bash dashboard-gen.sh <your uid> 

• replace <your uid> with your Prometheus datasource uid.

• now head to Grafana dashboards and hit new > import then copy the dashboard Json file and paste it into Import via panel json

• hit the load button and Done!

TO-DO

• [x] Disk I/O usage
• [x] Network I/O Usage
• [x] Add metrics in units of byte
• [x] Check and Unregister stat metrics for containers that are not running
• [ ] Design grafana dashboards and share them on grafana cloud
• [ ] Design and develop a static website to showcase Documentation, new features, etc.
