Here are some admin tasks related to the INFRA module (because who doesn’t love infrastructure management?):
Install INFRA
Use the infra.yml playbook to install the INFRA module on Infra nodes:
./infra.yml # Install INFRA module on infra group Remove INFRA
Use the infra-rm.yml playbook to uninstall the INFRA module from Infra nodes:
./infra-rm.yml # Uninstall INFRA module from infra group Expand INFRA
To scale out an existing INFRA deployment, first modify the infra group by adding new node IPs and assigning unique infra_seq numbers:
all: children: infra: hosts: 10.10.10.10: { infra_seq: 1 } # Existing node #1 10.10.10.11: { infra_seq: 2 } # New node #2 (fresh meat!) Then use the infra.yml playbook to install INFRA on the new node:
./infra.yml -l 10.10.10.11 # Install INFRA on the new node Local Repo
Use these playbook tasks to manage local package repositories (YUM/APT) on Infra nodes (because who doesn’t love a good package party?):
./infra.yml -t repo # Create local repo from internet or offline packages ./infra.yml -t repo_dir # Create local repo directory ./infra.yml -t repo_check # Check if local repo exists ./infra.yml -t repo_prepare # Use existing local repo if available ./infra.yml -t repo_build # Build local repo from upstream if not exists ./infra.yml -t repo_upstream # Add upstream repo/list files ./infra.yml -t repo_remove # Remove existing repo files if repo_remove=true ./infra.yml -t repo_add # Add upstream repo files to /etc/yum.repos.d (or apt) ./infra.yml -t repo_url_pkg # Download packages defined in repo_url_packages ./infra.yml -t repo_cache # Create metadata cache with yum makecache / apt update ./infra.yml -t repo_boot_pkg # Install bootstrap packages (createrepo_c, yum-utils, etc) ./infra.yml -t repo_pkg # Download packages & deps from upstream ./infra.yml -t repo_create # Create local repo with createrepo_c / dpkg-dev ./infra.yml -t repo_use # Add new repo to /etc/yum.repos.d | apt sources ./infra.yml -t repo_nginx # Start nginx as file server if not running Commonly used commands (the greatest hits):
./infra.yml -t repo_upstream # Add upstream repos defined in repo_upstream ./infra.yml -t repo_pkg # Download packages and their dependencies ./infra.yml -t repo_create # Create/update local yum/apt repo Managing Nginx
./infra.yml -t nginx # Reset Nginx component ./infra.yml -t nginx_index # Re-render Nginx homepage ./infra.yml -t nginx_config,nginx_reload # Re-render config & expose new upstream services If users specify a cert name in the certbot field of infra_portal, you can get free HTTPS certs with certbot:
# Get free HTTPS certs for real domains with certbot (SSL all the things!) ./infra.yml -t nginx_certbot,nginx_reload -e certbot_sign=true Manage Infra Components
Use these playbook tasks to manage infrastructure components on Infra nodes (it’s like conducting an orchestra, but with servers):
./infra.yml -t infra # Configure infrastructure ./infra.yml -t infra_env # Configure env vars: env_dir, env_pg, env_pgadmin, env_var ./infra.yml -t infra_pkg # Install required packages: infra_pkg_yum, infra_pkg_pip ./infra.yml -t infra_user # Setup infra OS user group ./infra.yml -t infra_cert # Issue certs for infra components ./infra.yml -t dns # Configure DNSMasq: dns_config, dns_record, dns_launch ./infra.yml -t nginx # Configure Nginx: nginx_config, nginx_cert, nginx_static, nginx_launch, nginx_exporter ./infra.yml -t prometheus # Configure Prometheus: prometheus_clean, prometheus_dir, prometheus_config, prometheus_launch, prometheus_reload ./infra.yml -t alertmanager # Configure AlertManager: alertmanager_config, alertmanager_launch ./infra.yml -t pushgateway # Configure PushGateway: pushgateway_config, pushgateway_launch ./infra.yml -t blackbox # Configure Blackbox Exporter: blackbox_launch ./infra.yml -t grafana # Configure Grafana: grafana_clean, grafana_config, grafana_plugin, grafana_launch, grafana_provision ./infra.yml -t loki # Configure Loki: loki_clean, loki_dir, loki_config, loki_launch ./infra.yml -t infra_register # Register infra components to prometheus Other useful tasks (for when you need that extra infrastructure TLC):
./infra.yml -t nginx_index # Re-render Nginx homepage ./infra.yml -t nginx_config,nginx_reload # Re-render config & expose new upstream services ./infra.yml -t prometheus_conf,prometheus_reload # Re-generate Prometheus config & reload ./infra.yml -t prometheus_rule,prometheus_reload # Re-copy rules & alerts, then reload ./infra.yml -t grafana_plugin # Download Grafana plugins (VPN might be needed) Feedback
