Docker Prerequisites

Version 1.6.9-option-2 | Updated: August 07, 2026

Docker Prerequisites

1. Install Docker and Docker Compose on All Linux Servers

Target servers: acs1, acs2, hc1, hc2, db, *-api servers

Before installing exporters, ensure that Docker and Docker Compose are installed on all target servers (except Windows-based servers).

Automated Installation (Recommended)

Use the automated installation script:

# If repository is already cloned:
cd /opt/grafana
sudo bash /opt/grafana/misc/install-docker.sh

# Or via one-command bootstrap (installs Docker automatically):
curl -fsSL https://hub.friendly-tech.com/bootstrap/install.sh | sudo bash -s -- PROMETHEUS_IP

The script automatically:

  • ✅ Detects your OS and package manager

  • ✅ Fixes EOL repos (CentOS 7/8)

  • ✅ Installs Docker CE from official repository

  • ✅ Installs Docker Compose plugin (falls back to static binary if needed)

  • ✅ Enables and starts Docker service

  • ✅ Verifies installation

Verify Installation

docker -v
docker compose version

Expected output (versions may vary):

Docker version 28.0.1, build 068a01e
Docker Compose version v2.33.1
