# 02_install_docker.sh - Docker and Docker Compose installation
|
|
# =============================================================================
|
|
# Installs Docker Engine and Docker Compose plugin from the official repository:
|
|
# - Skips installation if Docker is already present
|
|
# - Adds Docker's official GPG key and APT repository
|
|
# - Installs docker-ce, docker-ce-cli, containerd.io, and compose plugin
|
|
# - Adds the invoking user to the 'docker' group
|
|
# - Includes retry logic for apt commands (handles lock contention)
|
|
#
|
|
# Required: Must be run as root (sudo) on Ubuntu
