python - jinja2 nested variables -


i learning jinja2 , unsure on how address variables correct way:

here variables in yaml:

--- hosts:    app201.acme.com: {eth0: {ip: 46.0.0.1, netmask: 255.255.255.255}}    graphite.acme.com: {eth0: {ip: 46.0.0.2, netmask: 255.255.255.255},                        eth0.1: {ip: 10.2.90.1, netmask: 255.255.255.255}}

and here jinja2 template:

{{ fqdn }} {% interface in hosts[fqdn] %}     {{ interface }}     {{ hosts[fqdn].interface.ip }} << doesn't work     {{ hosts[fqdn].{{ interface }}.ip }} << doesn't work     {{ interface.ip }} << doesn't work {% endfor %}

so output looks since can't access second dimension of yaml hash.

graphite.acme.com eth0.1

eth0

the variable hosts dict. correct way access values in dict use [] operator.

{{ fqdn }} {% interface in hosts[fqdn] %}     {{ interface }}     {{ hosts[fqdn][interface]['ip'] }} {% endfor %}

. operator used access attribute of object.
