Prometheus

Simple run:

docker run --name prometheus -d -p 127.0.0.1:9090:9090 prom/prometheus

Override the config file path:

docker run --name prometheus -d -p 127.0.0.1:9090:9090 \
  prom/prometheus \
  --config.file=/etc/prometheus/custom.yml \
  --storage.tsdb.path=/prometheus

docker run --name prometheus -d -p 127.0.0.1:9090:9090 \
  prom/prometheus \
  --config.file=/etc/prometheus/prometheus.yml \
  --storage.tsdb.path=/custom/path

Override both:

docker run --name prometheus -d -p 127.0.0.1:9090:9090 \
  prom/prometheus \
  --config.file=/etc/prometheus/prometheus.yml \
  --storage.tsdb.path=/prometheus \
  --log.level=debug

Important paths from the Dockerfile

• /etc/prometheus/prometheus.yml — default config file location
• /prometheus — default storage path (also a VOLUME)
• Port 9090 — exposed port
