Nice work, you committed a Dockerfile. You'll notice at the end of the Dockerfile, we refer to an entrypoint script.

ENTRYPOINT ["/entrypoint.sh"]

The entrypoint.sh script will be run in Docker, and it will define what the action is really going to be doing.

Step 2: Add the action's script

An entrypoint script must exist in our repository so that Docker has something to execute.

⌨️ Activity: Add an entrypoint script and commit it to your branch

1. As a part of this branch and pull request, create a file in the ./action-a/ directory titled entrypoint.sh
2. Add the following content to the entrypoint.sh file:

   #!/bin/sh -l
   
   sh -c "echo Hello world my name is $MY_NAME"

3. Working locally, ensure the script is executable:

   chmod +x action-a/entrypoint.sh

4. Stage and commit the changes
5. Push the changes to GitHub

I'll respond when I detect a new commit on this branch.

Almost there! Your script is present, but it's not executable.

⌨️ Activity: Make your script executable

Assuming you've only worked on the web UI, and not locally until now, follow these instructions to make the script executable:

1. Open your favorite shell
2. Clone the repository:

   git clone https://github.com/dennym/hello-github-actions.git
   cd hello-github-actions

3. Checkout to the branch in this pull request:

   git checkout implement-first-action

4. Make the script executable:

   chmod +x action-a/entrypoint.sh

5. Stage and commit the change:

   git add action-a/entrypoint.sh
   git commit -m "make entrypoint script executable"

6. Push the branch to GitHub:

   git push

When I detect your new commit, I'll respond in this pull request.
