I have a shell command with json on it. I need some assistance, please, in
quoting it properly.
This is an attempt to execute an aws command-line command. I realize that
there are a massive number of aws aws modules, but unfortunately, my *bota*
is broken, so I can't use anything that relies on python making api calls.
Upcoming is a project to move to python 3 in the hopes of fixing pythons
ability to do api work. So I'm stuck with command line.
My playbook says:
- name: add to Github Enterprise Security Group
shell: aws ec2 authorize-security-group-ingress --group-name
GithubHappy --ip-permissions '[{"IpProtocol": "tcp","FromPort":22,"ToPort":
22,"IpRanges": [{"CidrIp":
"{{external}}/32","Description":"{{servername}}"}]}]'
and my error reads:
RROR! We were unable to read either as JSON nor YAML, these are the errors
we got from each:
JSON: No JSON object could be decoded
Syntax Error while loading YAML.
mapping values are not allowed in this context
The error appears to be in '/usr/local/ansible/playbooks/newserver.yml':
line 28, column 112, but may
be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
- name: add to Github Enterprise Security Group
shell: aws ec2 authorize-security-group-ingress --group-name
GithubHappy --ip-permissions "'[{"IpProtocol":
"tcp","FromPort":22,"ToPort": 22,"IpRanges": [{"CidrIp":
"{{external}}/32","Description":"{{servername}}"}]}]'"
^ here
We could be wrong, but this one looks like it might be an issue with
missing quotes. Always quote template expression brackets when they
start a value. For instance:
with_items:
- {{ foo }}
Should be written as:
with_items:
- "{{ foo }}"
I've tried quoting the entire thing with both single quotes and then with
double quotes, escaping the embedded quotes with backslashes. I've tried
putting quotes in jinja curlies. such as {{ '"' }} . Just about every
permutation I can think of.
Is this even possible? Should I put the aws command in a shell script and
run that? Inquiring minds want to know :)
Thanks.
