I have a task like this in a playbook. The ansible_ssh_user is 'root'
for this host.
- cron:
hour: 00
job: /home/backup/backup.sh
name: baserock.org data backup
user: backup
Running it gave me the following error:
TASK: [backup cron job, runs every day at midnight] ***************************
failed: [baserock-backup1] => {"failed": true}
msg: crontab: can't open '/tmp/crontabvVjoZe': Permission denied
crontab: user backup cannot read /tmp/crontabvVjoZe
The temporary file created by the 'cron' module is created with the
Python tempfile.mkstemp() function. This creates a file that is readable
only by 'root' (mode 600). The Busybox `crontab` program then checks if
the file is readable by the 'backup' user, and fails if it isn't. So we
need to make sure the file is world-readable before running `crontab`.
This was originally required to allow other methods in SourcesList to
fail, but subsequent changes rendered that unnecessary, and it's just
a cleanup now, and avoids passing in module separately to save().
1. Don't test check_mode in both the caller and in the callee.
2. Don't test HAVE_PYTHON_APT inside an if that tests HAVE_PYTHON_APT
3. Don't be irritatingly vague about why the module fails ("You may be
seeing this because…").
Note that if «apt-get -y install python-apt» succeeds with rc==0, but
for some reason python_apt is not usable afterwards, this will break
because the imports in install_python_apt aren't wrapped inside a
try/except.
In other words, we assume that install_python_apt either succeeds or
fails with a traceback. This commit doesn't affect that behaviour.
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')
