Question:
I need to properly escape single and double quotes in an ansible playbook in order to set the environment variable. None of this works:
|
1 2 3 4 5 6 7 8 9 10 11 12 |
- name: Set environment variable command: > export EXTRA_CONFIG=“'”{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}“'” - name: Set environment variable command: > export EXTRA_CONFIG=''{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}'' - name: Set environment variable command: > export EXTRA_CONFIG=''{\"client\": {\"subscriptions\": [\"DIND-Worker\"], \"cluster\": \"internal\"}}'' |
Looked at this:
http://yaml.org/spec/current.html#id2532720
https://github.com/dotmaster/toYaml/issues/1
The error message I get is:
|
1 2 |
fatal: [ip.address]: FAILED! => {"changed": false, "cmd": "export 'EXTRA_CONFIG={\"client\":' '{\"subscriptions\":' '[\"DIND-Worker\"],' '\"cluster\":' '\"internal\"}}'", "failed": true, "msg": "[Errno 2] No such file or directory", "rc": 2} |
Answer:
> starts a block scalar, in which you do not need to escape anything at all (and there are no escape sequences processed). So assuming you want single quotes around your JSON-like value, just do:
|
1 2 3 4 |
- name: Set environment variable command: > export EXTRA_CONFIG='{"client": {"subscriptions": ["DIND-Worker"], "cluster": "internal"}}' |
Edit: Also be aware that a folded scalar by default includes a trailing newline character. If you do not want to have this, just use >- instead of >.
