Ansible configuration for the Netz39 infrastructure

All our hosts running docker can put their metrics into our influxdb now. Note: not all docker hosts do this (yet), because the influxdb is currently only reachable from within the local space internal network in our rooms.

LOGUSER=<loguser>
SSH_KEY=<absolute/path/to/ssh/private/key>
ansible-playbook setup-ssh.yml --ask-vault-pass -e "setup_ssh_logname=$LOGUSER" -e "setup_ssh_key=$SSH_KEY"
Edit vault encrypted vars files
ansible-vault edit group_vars/all/vault
Call with
ansible-playbook --ask-vault-pass main.yml
You need to provide a user with sudo rights and the vault password.
Verify Changes

ansible-playbook --ask-vault-pass main.yml --check --diff
HTTPS ingress configuration
HTTPS ingress is controlled by the server holmium and forwarded to the configured servers.
To set up a new HTTPS vhost, the following steps need to be taken:
- Select a domain (for internal services we use sub-domains of
.n39.eu). - Create an external CNAME from this domain to
dyndns.n39.eu. - Create an internal DNS entry in the Descartes DNS config. This is usually an alias on an existing server.
- Add the entry to the holmium playbook.
- Set up Dehydrated and vhost on the target host, e.g. using
setup_http_site_proxy.
Do not forget to execute all playbooks with relevant changes.
