Public version of this repository: https://github.com/voc/cm/ansible/

To manage hosts with ansible you need to install ansible > 2.3 on your machine.

See https://docs.ansible.com/ansible/intro_installation.html for instructions

Syntax validation.

ansible-playbook -i inventory/event -l mixers site.yml --syntax-check

Basic ansible call to deploy new config to a specific host.

./ansible-playbook-keepass -u root -i inventory/event -l 192.168.122.1 site.yml

Basic ansible call to deploy new config to a set of hosts on an event.

./ansible-playbook-keepass -u voc --become --become-method=sudo -i inventory/event -l saal1 site.yml

Also have a look at the 'Usefull combinations' section of this page.

In case you need to do a lot of playbook runs you can also set the password using the following although it is not recommended.

export KEEPASS_PW='…'
./ansible-playbook-keepass … site.yml

What you need:

• install plain debian
• setting hostname to router.lan.c3voc.de
• make sure you have two network interfaces configured with names pbl (public) and int (internal)
• run ansible to deploy config

You have to name the monitoring host monitoring.lan.c3voc.de. After deployment, you have to run checkmk -I && checkmk -O inventory each host.

Have a look into TODO file.

• ansible-doc -l lists all available modules
• ansible-doc $module opens a very helpful knowledge page for a given module
• Documentation Page

• Change nginx config on all relays: --tags nginx,config
• Deploy only streaming website: --tags deploy_website
  • e.g. ./ansible-playbook-keepass --tags deploy_website -i event loadbalancers.yml
• Deploy encoder setting for a conference
  • edit groupvars/all and groupvars/saal*
  • ./ansible-playbook-keepass -i inventory/event --limit encoder1.lan.c3voc.de --tags encodermode site.yml
  • or ./ansible-playbook-keepass -i inventory/event --limit encoder1.lan.c3voc.de --tags voctomix site.yml
  • or ./ansible-playbook-keepass -i inventory/event -l saal5 --tags voctomix site.yml

    • Debug without rerunning working tasks
      • KEEPASS="${KEEPASS}" KEEPASS_PW="${KEEPASS_PW}" python3 `which ansible-playbook` -i inventory/event -l saal5 --tags voctomix --start-at-task="encoder : create recording script" encoder.yml
