Building your first Execution Environment

We are going to build an EE that represents an Ansible control node containing standard packages such as ansible-core and Python in addition to an Ansible collection (community.postgresql) and its dependency (the psycopg2-binary Python connector).

To build your first EE:

Create a project folder on your filesystem.
```
mkdir my_first_ee && cd my_first_ee
```
Create a execution-environment.yml file that specifies dependencies to include in the image.
Build a EE container image called postgresql_ee.

If you use docker, add the --container-runtime docker argument.
```
ansible-builder build --tag postgresql_ee
```

List container images to verify that you built it successfully.

podman image list

localhost/postgresql_ee          latest      2e866777269b  6 minutes ago  1.11 GB

You can verify the image you created by inspecting the Containerfile or Dockerfile in the context directory to view its configuration.

less context/Containerfile

You can also use Ansible Navigator to view detailed information about the image.

Run the ansible-navigator command, type :images in the TUI, and then choose postgresql_ee.

Proceed to Running your EE and test the EE you just built.
