cleanstart/prometheus-mysqld-exporter repository overview

Verified PROMETHEUS-MYSQLD-EXPORTER Container Image

A hardened, minimal PROMETHEUS-MYSQLD-EXPORTER container image built from source with verifiable software provenance and an SBOM, designed for secure production deployments.

For additional versions including FIPS support, explore CleanStart Images — secure, hardened container images⁠

⁠Pull Latest Image

Download the container image from the registry

docker pull cleanstart/prometheus-mysqld-exporter:latest

docker pull cleanstart/prometheus-mysqld-exporter:latest-dev

Note: cleanstart/prometheus-mysqld-exporter:latest does not support the standard DATA_SOURCE_NAME environment variable used by the upstream mysqld_exporter — instead it requires a .my.cnf config file mounted into the container and the --config.my-cnf= flag passed as an argument; to resolve, create a Kubernetes ConfigMap containing a [client] section with user, password, host, and port, mount it as a volume, and add --config.my-cnf=/etc/mysql/.my.cnf to the container args.

⁠Create .my.cnf on host

cat > /tmp/.my.cnf << 'EOF'
[client]
user=exporter
password=exporterpassword
host=mysql-host
port=3306
EOF

⁠Basic Run

Run the container with basic configuration

docker run -it --name prometheus-mysqld-exporter \
  -v /tmp/.my.cnf:/etc/mysql/.my.cnf:ro \
  cleanstart/prometheus-mysqld-exporter:latest \
  --config.my-cnf=/etc/mysql/.my.cnf

⁠Production Deployment

Deploy with production security settings

docker run -d --name prometheus-mysqld-exporter-prod \
  --security-opt=no-new-privileges \
  --user 1000:1000 \
  --restart unless-stopped \
  -p 9104:9104 \
  -v /tmp/.my.cnf:/etc/mysql/.my.cnf:ro \
  cleanstart/prometheus-mysqld-exporter:latest \
  --config.my-cnf=/etc/mysql/.my.cnf

Volume Mount Mount local directory for persistent data

docker run -v /app:/app \
  -v /tmp/.my.cnf:/etc/mysql/.my.cnf:ro \
  cleanstart/prometheus-mysqld-exporter:latest \
  --config.my-cnf=/etc/mysql/.my.cnf

Port Forwarding Run with custom port mappings

docker run -p 9104:9104 \
  -v /tmp/.my.cnf:/etc/mysql/.my.cnf:ro \
  cleanstart/prometheus-mysqld-exporter:latest \
  --config.my-cnf=/etc/mysql/.my.cnf

With Additional Collectors Enable specific MySQL metric collectors

docker run -d --name prometheus-mysqld-exporter-full \
  -p 9104:9104 \
  -v /tmp/.my.cnf:/etc/mysql/.my.cnf:ro \
  cleanstart/prometheus-mysqld-exporter:latest \
  --config.my-cnf=/etc/mysql/.my.cnf \
  --collect.global_status \
  --collect.global_variables \
  --collect.info_schema.innodb_metrics \
  --collect.info_schema.tables \
  --collect.perf_schema.eventsstatements
