When a group is created, an egress_rule ALLOW ALL to 0.0.0.0/0 is added
automatically but it's not reflected in the object returned by the AWS API
call. After creation we re-read the group for getting an updated object.
Suppose a pair of groups, A and B, depending on each other. One solution
for breaking the circular dependency at playbook level:
- declare group A without dependencies
- declare group B depending on A
- declare group A depending on B
This patch breaks the dependency at module level. Whenever a depended-on
group is missing it's first created. This approach requires only two tasks:
- declare group A depending on B (group B will be auto created)
- declare group B depending on A
When creating a group EC2 requires you to pass the group description. In
order to fullfil this, rules now accept the `group_desc` param. Note
that group description can't be changed once the group is created so
it's nice to keep descriptions in sync.
Concrete example:
- ec2_group:
name: mysql-client
description: MySQL Client
rules_egress:
- proto: tcp
from_port: 3306
to_port: 3306
group_name: mysql-server
group_desc: MySQL Server
- ec2_group:
name: mysql-server
description: MySQL Server
rules:
- proto: tcp
from_port: 3306
to_port: 3306
group_name: mysql-client
Services on Debian need to be disabled with 'disable' instead of 'remove'
to avoid them being enabled again when 'update-rc.d $service defaults' is run,
e.g. as part of a postinst script.
This fixes an issue related to the new run_command changes, whereby
Popen fails to run a command when an executable is specified + shell=False
and there are multiple positional arguments (see Popen docs for details)
hostnames in the known hosts file are typically stored as Hashed values, calling 'ssh-keyscan' with '-H' changes to output to the Hashed format so that the known_hosts file looks more consistent
