I came to this example today (line 50), and when I tried it, I got an error:
`msg: src and dest are required for creating links`
So, I changed **path** to **src** and it worked fine. Looks like the example is wrong, since the docs say "dest" is already an alias for "path", in which case we would have 2 "path" definitions.
I made a typo in a playbook and was great by:
ERROR: expecting dict; got: None
The issue was a single - on the last line of a playbook.
With the name of the file, I was able to see right away where the
error was.
While migrating my playbook to a newer ansible version, I faced
the error message "unknown init system, cannot enable service". It turned
out to be caused by a wrong service name that was not expanded anymore.
So by giving the name of the service that cannot be enabled and a more precise
reason, i think people will be able to diagnose their issue more easily.
This can be illustrated using this playbook:
- command: id
delegate_to: "{{ remote_server }}"
user: "{{ remote_user }}"
The error is to use 'user' instead of 'remote_user', but the error message
do not really mention it, so it can be a bit hard to spot.
If someone add ssh_args = " " to his .ansible.cfg, it will result into
strange failure later :
<server.example.org> ESTABLISH CONNECTION FOR USER: misc
<server.example.org> REMOTE_MODULE ping
<server.example.org> EXEC ['ssh', '-C', '-tt', '-q', ' ', '-o', 'KbdInteractiveAuthentication=no',
'-o', 'PreferredAuthentications=gssapi-with-mic,gssapi-keyex,hostbased,publickey', '-o', 'PasswordAuthentication=no',
'-o', 'ConnectTimeout=10', 'server.example.org', "/bin/sh -c 'mkdir -p /tmp/ansible-tmp-1397947711.21-5932460998838
&& chmod a+rx /tmp/ansible-tmp-1397947711.21-5932460998838 && echo /tmp/ansible-tmp-1397947711.21-5932460998838'"]
server.example.org | FAILED => SSH encountered an unknown error during the connection. We recommend you re-run the
command using -vvvv, which will enable SSH debugging output to help diagnose the issue
The root cause is the empty string between -q and -o, who kinda break mkdir.
If a delegated host is not found in the inventory specified
private_key_file for primary host was not used.
This allows running playbooks without having to define any inventory at
all and to use the same ssh private key for both primary host and
delegated one.
The JSON the Docker API returns includes the container's ENTRYPOINT value (if it has one) with the 'Command' value. So instead of checking if `container['Command'] == module.params['command']`, we just check that `container['Command'].endswith(module.params['command'])` so the entrypoint won't affect a container being properly classified as matching the module params or not.
Also I refactored a super-long `if` statement into some temporary variables - I did it to help me figure out what was going wrong, and then it makes the code more readable so I kept it.
