How to configure a connection between two ansible components

• You can connect AnsibleTask, AnsibleRole, AnsibleGalaxy, and Bash component with each other.

• The operation post_configure_source and add_source are executed in the same order as described in Section How to configure a connection between two Bash components.

• The environment variables of the SOURCE node and TARGET node are available in the operations as described in Environment variables for Bash script.

Examples

• Design the topology as belows.

• Connect the AnsibleTasks and the Bash component to the AnsibleRole component.

Figure 1. Ansible tasks relationship

Tip

You can find this example under New Application / Topology Template / Ansible-Bash-Connector.

• Select AnsibleRole.

• Set the port property to 27017.

• Set an env property with key FOO value bar.

Figure 2. Set environment variable on a target node

In the post_configure_source of the AnsibleTasks component, we can write a script to access the enrionment variables of the AnsibleRole component:

- debug:
    msg:
      - "Hello I am an ansible task {{ SOURCE_NODE }} executes on {{ SOURCE_HOST }} to connect with {{ TARGET_NODE }} at {{ TARGET_IP }}."
      - "I can access the env variable FOO on the target node {{ TARGET_NODE }} with value: {{ TARGET_FOO }}."

Expected result
