I have written a global role to spin-up ec2 instance at the address: `playbook/aws/spin-up-ec2/tasks/main.yaml ` and i am calling the role in a main file at the location `playbook/servers/cluster/tasks/main.yaml` to deploy three servers by calling the role in a loop for elastic\_ips in the below fashion. playbook/aws/spin-up-ec2/tasks/main.yaml ```auto - name: test hosts: localhost become: false gather_facts: false vars_files: - "vars/{{ env }}/main.yaml" pre_tasks: - name: Set all add_host: hostname={{ item }} groupname=all-servers with_items: '{{ elastic_ips }}' - name: add new instance to host group at runtime add_host: hostname={{ item }} groupname=nodes with_items: '{{ elastic_ips[1:] }}' tasks: - name: Run the role for each elastic IP include_role: name: ../../roles/aws/spin-up-ec2-instance vars: elastic_ip: "{{ elastic_ips }}" loop: "{{ elastic_ips }}" - name: On all servers hosts: all-servers become: false gather_facts: false roles: - install-dependencies - install-package - configure-package - name: On all nodes hosts: nodes become: false gather_facts: false roles: - setup-cluster ``` I am using the variable file at the below location: playbook/servers/cluster/vars/\/main.yaml The var file contains the some variables which are common for all the three servers. But there are some variables which are different for different instances. So i want these variables to be passed in the loop. I am not able to achieve this. The variables which are different for different instances are mentioned below; ```auto ebs_tags: Name: server-1/2/3 customer: abc cost_center: abc env_type: prod/uat ec2_tags: Name: server-1/2/3 customer: abc cost_center: abc env_type: prod/uat server_name: "server-1/2/3" elastic_ips: - 4.8.9.7 - 4.6.6.3 - 2.5.3.0 ``` I have tried different approaches but i get errors like item is undefined or we were unable to convert to dict: dictionary requested, could not parse JSON or key=value. Please help me resolve this issue and optimize the approach. Note: I can’t use the host/inventory file also the playbook/aws/spin-up-ec2/tasks/main.yaml role is a global role and uses variables as defined in the var file. No changes can be made in the variable key parameter. ---

You are using a loop, but not actually looping through? You would reference the current loop variable by using `item` An easy example from [Loops — Ansible Documentation](https://docs.ansible.com/ansible/latest/playbook_guide/playbooks_loops.html#iterating-over-a-simple-list:) ```auto - name: Add several users ansible.builtin.user: name: "{{ item }}" state: present groups: "wheel" loop: "{{ somelist }}" ``` So maybe this section needs to be changed like so? ```auto - name: Run the role for each elastic IP include_role: name: ../../roles/aws/spin-up-ec2-instance vars: #elastic_ip: "{{ elastic_ips }}" elastic_ip: "{{ item }}" loop: "{{ elastic_ips }}" ``` ---

@jrglynn2 I tried this as well, but it gives me the below mentioned error. ```auto TASK [../../roles/aws/spin-up-ec2-instance : Spin up the EC2 instance] ************************************************************************************************************************************* fatal: [localhost]: FAILED! => {"changed": false, "msg": "argument 'tags' is of type and we were unable to convert to dict: cannot be converted to a dict"} ``` ---

Hi, What is your argument ‘tags’ ? What are you trying to do with it in your role ? You obviously have a type mismatch, trying to pass a list to something expecting a dict, but it’s hard to debug without seeing what your role is doing. Could you share you role’s relevant task(s) ? Also, how was your playbook changed exactly for you to get this error ? ---

Same questions as @ptn … we don’t see `tags` in your initial code, so we don’t know where the issue is happening. When you run the command as `-vvv` and get this error, do you see that the task is trying to run against one of your `{{ elastic_ips }}` values? That would confirm whether the initial issue is resolved - the loop issue. This `tags` seems like an issue with a different part of code. ---

Hi @jrglynn2 @ptn thanks i got the solution i was looping elastic ip only now i modified the loop to use all the tags. ```auto --- - name: test hosts: localhost become: false gather_facts: false vars_files: - "vars/{{ env }}/main.yml" tasks: - name: Run the role for each elastic IP include_role: name: ../../roles/aws/spin-up-ec2-instance loop: "{{ server_variable }}" loop_control: loop_var: server_item vars: elastic_ip: "{{ server_item.elastic_ip }}" ec2_tags: "{{ server_item.ec2_tags }}" ebs_tags: "{{ server_item.ebs_tags }}" server_name: "{{ server_item.server_name }}" ``` var file ```auto server_variable: - ec2_tags: Name: RabbitMQ-1 customer: hsbc cost_center: hsbc env_type: prod ebs_tags: Name: RabbitMQ-1 customer: hsbc cost_center: hsbc env_type: prod server_name: RabbitMQ-1 elastic_ip: "34.198.209.77" - ec2_tags: Name: RabbitMQ-2 customer: hsbc cost_center: hsbc env_type: prod ebs_tags: Name: RabbitMQ-2 customer: hsbc cost_center: hsbc env_type: prod server_name: RabbitMQ-2 elastic_ip: "44.196.206.193" - ec2_tags: Name: RabbitMQ-3 customer: hsbc cost_center: hsbc env_type: prod ebs_tags: Name: RabbitMQ-3 customer: hsbc cost_center: hsbc env_type: prod server_name: RabbitMQ-3 elastic_ip: "52.45.63.110" ``` ---
