I'm trying to do something that I thought was fairly straightforward but
I'm not having any luck. In a nutshell I need to delete a tag from an EC2
instance, but the name is a concatenation of a variable and a constant.
What I'm trying is basically this:
vars:
- foo: sometag
- name: Delete tag
local_action: ec2_tag state=absent
aws_access_key={{ AWS_ACCESS_KEY_ID }}
aws_secret_key={{ AWS_SECRET_ACCESS_KEY }}
region={{ AWS_REGION }}
resource={{ instanceId }}
args:
tags:
"{{ foo }}-bar": some_value
The problem is that "{{ foo }}-bar" doesn't seem to get converted into
"sometag-bar" before the module is called. (foo is actually a fact of the
host, so I can't just statically set the tag name) Bug? Feature?
Unrelated issue (or maybe not), but also dealing with the ec2_tag module:
What's the correct way to reference the value of a tag when trying to
delete it? For whatever reason when using "state=absent" the ec2_module
will only remove a tag if you specify both the name and the current value
of the tag. In other words, if you have an instance with a tag named foo
that has a value of "bar" then the following will not remove the tag:
- name: Delete tag
local_action: ec2_tag state=absent
aws_access_key={{ AWS_ACCESS_KEY_ID }}
aws_secret_key={{ AWS_SECRET_ACCESS_KEY }}
region={{ AWS_REGION }}
resource={{ instanceId }}
args:
tags:
foo: ''
The only way to get the ec2_tag module to actually delete the tag is to
specify both the name & value of the tag, so you need to set the args as:
args:
tags:
foo: bar
Because of this, and the fact that some of our tags have dynamic values,
I'm trying to do something like this:
- name: Get tags
local_action: ec2_tag state=list
aws_access_key={{ AWS_ACCESS_KEY_ID }}
aws_secret_key={{ AWS_SECRET_ACCESS_KEY }}
region={{ AWS_REGION }}
resource={{ instanceId }}
register: mytags
- name: Delete env tag
local_action: ec2_tag state=absent
aws_access_key={{ AWS_ACCESS_KEY_ID }}
aws_secret_key={{ AWS_SECRET_ACCESS_KEY }}
region={{ AWS_REGION }}
resource={{ instanceId }}
args:
tags:
foo: mytags[ foo ]
But I'm unable to get anything here to work either, even if I set the name
of the tag to a static value. What's the proper way to reference the tags
from "state=list" so that you can do something like delete a tag?
