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:)
Django since version 1.7 has built-in migrations, so no need to have south installed with recent django versions. The 'migrate' command works with built-in migrations without any change, but the output is different than the output produced by south, which breaks idempotence. This commit fixes this.
This is mlosev's patch (from #1208), rebased against devel as of
2790af2. It resolves#1707, which was caused by an API incompatibility
between the docker module and server API version 1.19.
There was a catch-all `except` statement in `create_containers`:
try:
containers = do_create(count, params)
except:
self.pull_image()
containers = do_create(count, params)
This would mask a variety of errors that should be exposed, including
API compatability errors (as in #1707) and common Python exceptions (KeyError, ValueError, etc) that could result from errors in the code.
This change makes the `except` statement more specific, and only attempts to pull the image and start a container if the original create attempt failed due to a 404 error from the docker API.
The `docker` Python module only accepts `None` or `'host'` as arguments.
This makes it difficult to conditionally set the `pid` attribute using
standard Ansible syntax.
This change converts any value that evaluates as boolean `False` to
`None`, which includes empty strings:
pid:
As well as an explicit `false`:
pid: false
This permits the following to work as intended:
- hosts: localhost
tasks:
- name: starting container
docker:
docker_api_version: 1.18
image: larsks/mini-httpd
name: web
pid: "{{ container_pid|default('') }}"
If `container_pid` is set to `host` somewhere, this will create a
Docker container with `pid=host`; otherwise, this will create a
container with normal isolated pid namespace.
