在Ansible模板中生成元组变量 [英] Generating tuples variables in ansible templates

问题描述

我正在尝试设置一个剧本来部署一个influxdb集群.除了使用 INfluxDB群集客户端

I'm trying to setup a playbook to deploy an influxdb cluster. Everything works fine except that we use INfluxDB Cluster Client

我正在生成一个production.py文件，该文件会被我们的脚本读取.

I am generating a production.py file which is read by our script.

InfluxdbClusterClient正在等待元组列出所有Influx服务器:

InfluxdbClusterClient is waiting for a tuple to list all influx servers :

'hosts': [('fr-influxdb-prod-1', 8086), ('fr-influxdb-prod-2', 8086), ('fr-influxdb-prod-3', 8086)],

我正在尝试从ansible变量生成那些元组，但是我不知道该怎么写.我试过了:

I am trying to generate those tuples from ansible variables but I don't know how to to dat. I tried:

/ Variables /
influxdb_hosts: [('fr-influxdb-prod-1', 8086), ('fr-influxdb-prod-2', 8086), ('fr-influxdb-prod-3', 8086)]

/ Template / 
....
'hosts': {{influxdb_hosts}},
...

不幸的是，它无法正常工作，因为Ansible正在转换列表中的元组(即 [('fr-influxdb-prod-1'，8086)，('fr-influxdb-prod-2'，8086)，('fr-influxdb-prod-3'，8086)] 变成 [('fr-influxdb-prod-1'，" 8086)，"('fr-influxdb-prod-3'-prod-2'，" 8086)，"('fr-influxdb-prod-3'，" 8086)]"

Unfortunately it doesn't work as expected as Ansible is transforming the tuple in list (ie [('fr-influxdb-prod-1', 8086), ('fr-influxdb-prod-2', 8086), ('fr-influxdb-prod-3', 8086)] becomes ["('fr-influxdb-prod-1'", "8086)", "('fr-influxdb-prod-2'"," 8086)"," ('fr-influxdb-prod-3'"," 8086)]"

您看到我在做什么吗?

推荐答案

您可以使用折叠块标量来通知Ansible，该参数是不应解析的字符串:

You can use folded block scalar to inform Ansible that the argument is a string which shouldn't be parsed:

influxdb_hosts: >
  [('fr-influxdb-prod-1', 8086), ('fr-influxdb-prod-2', 8086), ('fr-influxdb-prod-3', 8086)],

这是生成的目标文件:

'hosts': [('fr-influxdb-prod-1', 8086), ('fr-influxdb-prod-2', 8086), ('fr-influxdb-prod-3', 8086)],
