---------- |
|
**Summary:** post data to url |
|
|
|
This module can be used to post data to a remote host after boot is complete. |
|
If the post url contains the string ``$INSTANCE_ID`` it will be replaced with |
|
the id of the current instance. Either all data can be posted or a list of |
|
keys to post. Available keys are: |
|
|
|
- ``pub_key_rsa`` |
|
- ``pub_key_ecdsa`` |
|
- ``pub_key_ed25519`` |
|
- ``instance_id`` |
|
- ``hostname`` |
|
- ``fdqn`` |
|
|
|
**Internal name:** ``cc_phone_home`` |
|
|
|
**Module frequency:** per instance |
|
|
|
**Supported distros:** all |
|
|
|
**Config keys**:: |
