Some things cannot be updated via the API, so check for those and fail
if the user is wanting to update them. Also don't try to update ipv6
stuff, as that doesn't work and will cause a traceback.
If `docker.__version__` contains non-digit characters, such as:
>>> import docker
>>> docker.__version__
'1.4.0-dev'
Then `get_docker_py_versioninfo` will fail with:
ValueError: invalid literal for int() with base 10: '0-de'
This patch corrects the parsing of the version string so that
`get_docker_py_versioninfo` in this example would return:
(1, 4, 0, '-dev')
If `password` is defined as `*` `useradd` or `usermod` returns an error:
msg: usermod: Invalid password: `*'
This works very well on Linux host to not define any password for a
user (mainly useful if your setup is only based on SSH keys for
auth). On OpenBSD this does not work, so we have to ignore the encrypted
password parameter if it defined as `*`.
Docs imply the mysql_variables is used to operate a single variable therefore
- fail before making any db connections if variable is not set
- validate chars for mysql variable name with re.match(^[a-z0-9_]+)
- use "SHOW VARIABLE WHERE Variable_name" instead of LIKE search
- getvariable() returns only the value or None if variable is not found
- the module returns only the found variable value instead of tuple for easier operation eg. as registere variable in tasks
My project is using Ansible to automate cloud build process. Ansible has a core module gce.py for managing GCE instances.
We've come across a use case that's not yet supported - when executing ansible-playbook, if a child template is included, then metadata which is defined in and propagated from the mother template is treated as string type and not parsed correctly(which instead is dictionary type), and triggers release flow failure.
We currently put some fix by explicitly casting metadata to string type in our own branch, but would like to contribute the fix to Ansible so that everyone onboarding GCE and using Ansible for release management could benefit from it, or hear owner's opinion on fixing the issue if there's a better fix in owner's mind:)
