ansible ver=2.0.2 When I’m trying to add more than one host to a group its only adding the first one in the list. Here is my task to add hosts: - name: Add hosts group temporary inventory group add\_host: name={{ item.private\_ip }} groups=dynamic with\_items: “{{ ec2.instances }}” This task does use the ec2.instances properly and will do it for all the hosts that I have created: - name: Wait for SSH wait\_for: host: “{{ item.private\_ip }}” port: 22 delay: 10 timeout: 320 state: started with\_items: “{{ ec2.instances }}” So I’m creating 3 hosts and the add\_host task only adds the first one but the wait for ssh task will wait for all three and I get an ok back for the wait for ssh task on all three. ---

anyone have an idea of why this is working like this? I’ve tried all version of ansible 1.9/2.0.0/2.0.1/2.0.2/2.1 and all the same result. ---

It might help if you provided the output of your playbook run with `-v` so we can see what you are seeing. ---

I’m not quite positive what you are doing. You omitted the task that creates the instances. However it looks like you are targeting 3 hosts: aaa-frs-ans-test1 aaa-frs-ans-test2 aaa-frs-ans-test3 And you are creating 1 instance for each host. add\_host only runs on the first host in the group, so you see it only run for aaa-frs-ans-test1. It is called a host loop bypass plugin, meaning that it doesn’t execute for each host you target in your play. You are trying to loop ec2.instances, but there is only 1 host in that result, since you created a host on each instance, since vars are scoped to hosts. Instead of targeting those 3 hosts, maybe you should instead target just localhost, and build your ec2 instances using a with\_items to create 3 hosts. But again, still not really sure what you are doing, and if you have reasons for what you have done so far. ---

Here’s the create task: - hosts: ec2\_instances 4 connection: local 5 gather\_facts: true 6 tasks: 7 - name: Launch Instance 8 ec2: 9 group\_id: “{{ hostvars[inventory\_hostname].group\_id }}” 10 instance\_type: ‘t2.micro’ 11 image: “{{ hostvars[inventory\_hostname].image }}” 12 wait: true 13 region: ‘us-east-1’ 14 keypair: “{{ key\_pair }}” 15 vpc\_subnet\_id: “{{ subnet }}” 16 instance\_tags: “{{ hostvars[inventory\_hostname].tags }}” 17 register: ec2\_info but why does that module not loop through ec2.instances like the others do? Also there are examples online that do i that way of using the add\_hosts mod with {var}.instances. ---

That seems to be contradicting each other. Or is this (the local connection) something special use for ec2-stuff? Johannes ---

Yes when launching ec2 instances you use the local connection. They all launch fine and are able to be picked up by the wait for ssh task: - name: Wait for SSH wait\_for: host: “{{ item.private\_ip }}” port: 22 delay: 10 timeout: 320 state: started with\_items: “{{ ec2\_info.instances }}” just not the add\_host task. ---

is it an issue with the add\_host module? I even tried upgrading to 2.1 and still am experiencing the same thing. Can the add\_host module only add one host at a time? ---

No, I tried to explain this in a previous response. add\_host is what is called a “bypass host loop” plugin. This means that add\_host will only execute for the first host targeted by your `hosts` specification. Your `hosts` targets a group containing the following hosts: aaa-frs-ans-test1 aaa-frs-ans-test2 aaa-frs-ans-test3 As such, add\_host only runs for aaa-frs-ans-test1. The problem is with how you have structured your tasks. You have instructed ansible to build a new server, for each one of these servers. The results of your `ec2` variable that you register, get stored per host (aaa-frs-ans-test1, aaa-frs-ans-test2, aaa-frs-ans-test3). This means that `ec2.instances` only hold the results of a single host build, per host. Most people only target localhost, instead of a group that contains multiple hosts. And then they build servers with the ec2 module using exact\_count, or with\_items, then all of the results for building all new instances, are stored with 1 inventory host. So again, you are building 3 new instances, using 3 old instances, so effectively you end up with an `ec2` variable stored for each host (aaa-frs-ans-test1, aaa-frs-ans-test2, aaa-frs-ans-test3). However add\_host only runs on the first host (bypass host loop plugin), and thus only has access to the `ec2` var stored for aaa-frs-ans-test1. Another solution would be to do something like: - name: Add hosts group temporary inventory group add\_host: name={{ hostvars[item][‘ec2’].instances.0.private\_ip }} groups=dynamic with\_items: “{{ play\_hosts }}” However, that assumes you always have only created 1 instance via the ec2 task per host in the play. Another option, and this is completely untested, is to use the `extract` filter, something like: - name: Add hosts group temporary inventory group add\_host: name={{ item.private\_ip }} groups=dynamic with\_items: “{{ play\_hosts|map(‘extract’, hostvars, [‘ec2’, ‘instances’])|list }}” ---

Thanks for the deeper explanation, I get it now. When you say “Most people only target localhost, instead of a group that contains multiple hosts.” do you mean when I’m applying a role? Because in the same playbook s the ec2 instance(s) creation i’m apply a role(s) to the newly created instances. So the whole playbook is: - hosts: ec2\_test connection: local gather\_facts: true tasks: - name: Launch Instance ec2: group\_id: “{{ groupID }}” instance\_type: ‘t2.micro’ image: “{{ image }}” wait: true region: “{{ region }}” keypair: “{{ keypair }}” vpc\_subnet\_id: “{{ subnet }}” instance\_tags: Name: “{{ inventory\_hostname }}” ENV: “{{ tagEnv }}” register: ec2 - name: Add hosts to group add\_host: name=“{{ hostvars[item][‘ec2’].instances.0.private\_ip }}” groups=dynamic with\_items: “{{ play\_hosts }}” - name: Wait for SSH wait\_for: host: “{{ item.private\_ip }}” port: 22 delay: 10 timeout: 320 state: started with\_items: “{{ ec2.instances }}” - name: Wait a little longer for centos pause: seconds=20 - hosts: dynamic gather\_facts: yes sudo: yes roles: - hostname
