Application pushed to GitHub does not build in Travis CI

What do you want to do

When you push the Rails app built in Docker to GitHub, you want to run a test with Travis CI and build it.

Situation

Running the rails test inside the container on the Docker is fine.
I have confirmed that the app starts with localhost.

Background

git add.

After
git push origin master
I did.
git push origin master
In the process, Travis CI and GitHub are able to work together and should be built and tested, but not built.

What should I do?

Add

docs.travis-ci.com/user/tutorial
I would like to add the information in .
To get started with Travis CI using GitHub
By the way, regarding ② ③ に,
③So, isn't the green activate button the Sync Account button?
"When I press this, it becomes ""Sync form GitHub"", and it's hard for me to sync it."

Even if the screen appears to be finished, it will always be loading.

Thank you.
