Goal:

Context:

Lets show how you can help a team migrate their infrastructure to Docker containers..

Part 2 Activities:

Monitor the new environment w/Docker (stats) & Prometheus, you can see how to utilize a cool feature like Docker Compose & cAdvisor.

Lessons Learned:

• Create a Prometheus YAML File
  • vi prometheus.yml
• Create a Prometheus Service
  • vi docker-compose.yml
  • docker-compose up -d
  • docker ps
• Create Stats Shell
  • Investigate cAdvisor
  • Stats in Docker
  • Doper Stats

Create a Prometheus YAML File:

• Collect metrics & monitoring using Prometheus/cAdvisor to deploy containers using docker-compose

vi Prometheus.yml:

Create a Prometheus Service:

vi docker-compose.yml:

docker-compose up -d:

docker ps

Create Stats Shell:

Investigate cAdvisor:

Stats in Docker:

• docker stats

Doper Stats:

• vi stats.sh
• chmod a+x stats.sh
