Docker commands I use regularly:

1. Complete Environment Cleanup

docker-compose down --remove-orphans -v --rmi all

  • --remove-orphans: Deletes containers for services not in compose file

  • -v: Removes attached volumes

  • --rmi all: Deletes all images used by services

2. Run Image with Interactive Shell

docker run -it --entrypoint bash wazuh/wazuh-certs-generator:0.0.1

docker run -it --entrypoint bash ubuntu:focal

  • -it: Interactive terminal

  • --entrypoint bash: Overrides default to give shell access

3. Find Container IP Address

docker inspect -f '{{range.NetworkSettings.Networks}}{{.IPAddress}}{{end}}' $(docker ps | grep -i dashboard | awk '{print $1}')

  • docker ps | grep -i dashboard: Finds container with “dashboard” in name

  • awk '{print $1}': Extracts container ID

  • docker inspect -f: Formats output with Go template

  • Template extracts just the IP address

4. Build Custom Image

docker build -t wazuh-dashboard-anomaly-detector:4.7.1 wazuh-dashboard/. --no-cache
  • --no-cache ensures fresh build

5. Tag Image for Docker Hub

docker tag wazuh-dashboard-anomaly-detector:4.7.1 elwali/wazuh-dashboard-anomaly-detector:4.7.1
  • username/repository:version required before pushing to any registry.

6. Push Image to Docker Hub

docker push elwali/wazuh-dashboard-anomaly-detector:4.7.1

Make sure to meet the following requirements:

  • Must be logged in (docker login)

  • Proper permissions on repository

  • Correctly tagged image

7. System Cleanup

docker system prune

It removes:

  • Stopped containers

  • Dangling images

  • Unused networks

  • Build cache

More aggressive cleanup:

docker system prune -a --volumes
  • Removes all unused images and volumes
