URI and Until

Archives Ansible Project

I have a cluster of N nodes. Cluster status is reported by http://cluster_fqdn/health/. I want to do a rolling upgrade of every node in my cluster with serial: 1. I don’t want to proceed to the next node until http://cluster_fqdn/health/ reports the cluster is healthy.

Trying to use uri and until, but can’t seem to get the syntax quite right:

`

  • name: Await Cluster Healthy Status
    uri: url=http://{{host_ip}}/cluster_health/ return_content=yes
    register: cluster_health
    until: “green” in "{{cluster_health.content}}
    retries: 100
    delay: 10

`

errors out with:

ERROR: Syntax Error while loading YAML script, main.yml

Note: The error may actually appear before this position: line 67, column 18

register: cluster_health

until: “green” in “{{cluster_health.content}}”

I was going by the example here: http://docs.ansible.com/uri_module.html

I also tried using the example here (http://docs.ansible.com/playbooks_loops.html#do-until-loops)

`

  • name: Await Cluster Healthy Status
    uri: url=http://{{host_ip}}/cluster_health/ return_content=yes
    register: cluster_health
    until: cluster_health.content.contains(“green”) != -1
    retries: 100
    delay: 10
    `

but that fails with:

fatal: [prod.clustertest-elk-fxbo-1] => error while evaluating conditional: cluster_health.content.contains(“green”) != -1

Took me a while to realize I needed to install liburi module, but that’s a different story. I debugged ‘cluster_health’ var and it definitely contains the word “green”.

The error was ‘contains’ isn’t a method. ‘find’ is though.

I love Ansible, but the error reporting really leaves a lot to be desired. Still have no idea what was wrong with the first example. Maybe until and when have different conditional syntaxes?
