on python3, this means that we don't get bytes back by default. We
probably do want bytes here so modify our call to run_command so we get
bytes instead of text.
* Restart EC2 instances with multiple network interfaces
A previous bug, #3234, caused instances with multiple ENI's to fail when being
started or stopped because sourceDestCheck is a per-interface attribute, but we
use the boto global access to it (which only works when there's a single ENI).
This patch handles a variant of that bug that only surfaced when restarting an
instance, and catches the same type of exception.
* Default termination_protection to None instead of False
AWS defaults the value of termination_protection to False, so we don't
need to explicitly send `False` when the user hasn't specified a
termination protection level. Before this patch, the below pair of tasks
would:
1. Create an instance (enabling termination_protection)
2. Restart that instance (disabling termination_protection)
Now, the default None value would prevent the restart task from
disabling termination_protection.
```
- name: make an EC2 instance
ec2:
vpc_subnet_id: {{ subnet }}
instance_type: t2.micro
termination_protection: yes
exact_count: 1
count_tag:
Name: TestInstance
instance_tags:
Name: TestInstance
group_id: {{ group }}
image: ami-7172b611
wait: yes
- name: restart a protected EC2 instance
ec2:
vpc_subnet_id: {{ subnet }}
state: restarted
instance_tags:
Name: TestInstance
group_id: {{ group }}
image: ami-7172b611
wait: yes
```
The Conditional instance will now raise the AddConditionError and this
change instructs eos_command to catch the error and return a nicely formed
error message
