ec2_vpc default gw not working?

[Pablo Escobar]

Hi,

I have been doing some tests to deploy a ec2 vpc with ansible but I cannot manage to configure the default gw so the machines inside the vpc have no internet access.

After doing some debugging in my playbook I just copied&paste the example from the documentation in http://docs.ansible.com/ec2_vpc_module.html to see if it works but still I don't get the default gw in the vpc

This is the example I tried from documentation which is not working for me.  (just changing availability zone and region)  I am using ansible 1.8.2 in ubuntu14.04 with python 2.7.6

any clue about how to fix this?

# Full creation example with subnets and optional availability zones.
# The absence or presence of subnets deletes or creates them respectively.
      ec2_vpc:
        state: present
        cidr_block: 172.22.0.0/16
        resource_tags: { "Environment":"Development" }
        subnets:
          - cidr: 172.22.1.0/24
            az: us-west-2c
            resource_tags: { "Environment":"Dev", "Tier" : "Web" }
          - cidr: 172.22.2.0/24
            az: us-west-2b
            resource_tags: { "Environment":"Dev", "Tier" : "App" }
          - cidr: 172.22.3.0/24
            az: us-west-2a
            resource_tags: { "Environment":"Dev", "Tier" : "DB" }
        internet_gateway: True
        route_tables:
          - subnets:
              - 172.22.2.0/24
              - 172.22.3.0/24
            routes:
              - dest: 0.0.0.0/0
                gw: igw
          - subnets:
              - 172.22.1.0/24
            routes:
              - dest: 0.0.0.0/0
                gw: igw
        region: us-west-2
      register: vpc

thanks in advance,

Pablo

So you're saying that after running that the IGW is not associated with your subnet(s)?

Also, can you confirm that the routing tables have the correct subnets associations?

yes. I have to manually add the IGW to the vpc in the console so the machines have internet access

 

Also, can you confirm that the routing tables have the correct subnets associations?

in the routes section I only get this;

Destination       Target      Status         Propagated 

172.1.0.0/16     local          Active        No

In the "subnets associations" section I get this:

Subnet   CIDR

You do not have any subnet associations.

The following subnets have not been associated with any route tables and are therefore using the main table routes:

Subnet  CIDR

All your subnets are associated with a route table.

Just had a look at all my tasks involving ec2_vpc module and all of them have

internet_gateway: yes

I believe that is your problem. In that case, the documentation example should reflect this, as per the shown parameter values in the table.

I took a look at ec2_vpc.py and there isn't anything suggesting that True/False values wouldn't work, hence you get no error.

Hope this helps,

Dan.

     cidr_block: "{{ cidr_block }}"

     resource_tags: { "Name":"{{ vpc_name| default(test) }}_vpc" }

     subnets:

       - cidr: "{{ public_cidr }}"

         az: "{{ public_az }}"

         resource_tags: { "Name":"{{ vpc_name| default(test) }}_public_subnet" }

       - cidr: "{{ private_cidr }}"

here is my var/main.yml
