The code to determine the number of running instances could blow up
if the response from AWS did not actually contain any data. This code
makes it a bit smarter in handling, so that it will wait for a valid
response regardless of the wait condition.
Fixes#3980
Add support to existing rax module to honor the wait (and wait_timeout)
parameters on delete operations. This patch removes existing logic in favor of
the built-in pyrax.utils.wait_until method.
As it stands now, it is difficult to write idempotent tasks for digital
ocean droplets. Digital ocean assigns new nodes a random id when they
are provisioned and that id is the only key that can be used to identify
it in subsequent runs of that play.
The workflow previously involved manual intervention:
- write a play defining a new node with no specified id
- run it, collect the randomly assigned id by hand
- modify the play to add the id by hand so future runs don't create
duplicate nodes
- perform future re-runs that check if the node exists (by its id)
- if it does exist then do nothing.
- if it does not exist, then create it and return a *new random id*
- collect the new random id by hand, modify the playbook file, and
start all over.
Its a huge pain.
The modifications in this commit allow you to use the 'hostname' as a
primary key for idempotence with digital ocean. By default, digital
ocean will let you create as many hosts with the same hostname as you
like. Here, we provide an option to constrain the user to using only
unique hostnames.
The workflow will now look like:
- write a play defining a new node with a specified hostname and
"unique_name: true""
- run it, create the new node and move on.
- re-run it, notice that a node with that hostname is already created
and move on.
The EXAMPLES block here has two copies of the same docs,
one nicely formatted, the other less so.
It looks like a pass was made to clean up the docs but the old
cruftier ones were never removed.
Since deletion do not check the type of image or anything,
and since that's tedious to keep track of the image_id and
just adding noise to add image_id for nothing, this commit
just relax the requirement.

This extension was added less than 6 month ago, and so cannot be used on a release
older than Grizzly ( like Folsom ).

Both modules dealing with rax resources should use the same arguments
and environmental variables. The author of rax_clb_nodes did some things
better so sync rax with that effort.
Remove the reference to the unused "termination_list" parameter
in the ec2 module. The instance_ids parameter is the one that contains
the list of instance ids to be terminated.
Boto blindly assumes the us-east-1 region if you don't hardcode a
region in it's config, so you could end up attempting to modify ELB's
in one region from a totally different region. If a region isn't
specified then default to the region that the module is being run
within rather than the default us-east-1 region since it's a pretty
safe assumption that you intend to work on the ELB's within your
current region.
Also throw an error if a specified ELB instance doesn't exist. The old
behavior would be to silently succeed with changed=false, so if you had
so much as a typo in the name of your ELB (or were in the wrong region
like my initial testing) you wouldn't get a clear indication that a
problem had occurred.
The timeout parameter of glance-image was not being parsed into a
numeric type, causing the following error when specifying timeout:
msg: Error in creating image: unsupported operand type(s) for +: 'float' and 'str'
