Commit and Push Changes

In Getting Started With Docker, you moved most of the files from the shellhttpd.disabled folder to shellhttpd. You then built and tested a local version of the container.

In this chapter, you will work on the final adjustments before sending your changes to the remote repository. This triggers the FoundriesFactory® CI to start a new build, which compiles and publishes your application to™ hub.

Open a terminal on your host machine and navigate to the container folder used in the previous tutorial.

Edit shellhttpd/docker-compose.yml, changing the image back to

version: '3.2'

#    image: shellhttpd:1.0
    restart: always
      - 8080:${PORT-8080}
      MSG: "${MSG-Hello world}"

There should be one file left in the shellhttpd.disabled folder: docker-build.conf. Move it to the shellhttpd folder:

mv shellhttpd.disabled/docker-build.conf shellhttpd/

This file adds advanced configuration for a FoundriesFactory CI build. Without adding too much detail, one of the tasks of the FoundriesFactory CI is to execute commands after the container image is built. These commands verify that your container functions correctly.

Check the content of docker-build.conf:

cat shellhttpd/docker-build.conf


# Allow CI loop to unit test the container by running a command inside it

TEST_CMD tells the CI to run the command /bin/true. If this command fails for some reason, it will mark the container build as failed.

Use git status to verify all the changes:

git status

Example Output:

On branch main
Your branch is up to date with 'origin/main'.

Changes not staged for commit:
  (use "git add/rm <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
        deleted:    shellhttpd.disabled/Dockerfile
        deleted:    shellhttpd.disabled/docker-build.conf
        deleted:    shellhttpd.disabled/docker-compose.yml
        deleted:    shellhttpd.disabled/
Untracked files:
  (use "git add <file>..." to include in what will be committed)
no changes added to commit (use "git add" and/or "git commit -a")

Remove shellhttpd.disabled from git:

git rm -r shellhttpd.disabled/

Example Output:

rm 'shellhttpd.disabled/Dockerfile'
rm 'shellhttpd.disabled/docker-build.conf'
rm 'shellhttpd.disabled/docker-compose.yml'
rm 'shellhttpd.disabled/'

Add the shellhttpd folder:

git add shellhttpd/

Check the status again before we commit:

git status

Example Output:

On branch main
Your branch is up to date with 'origin/main'.
Changes to be committed:
  (use "git restore --staged <file>..." to unstage)
        renamed:    shellhttpd.disabled/Dockerfile -> shellhttpd/Dockerfile
        renamed:    shellhttpd.disabled/docker-build.conf -> shellhttpd/docker-build.conf
        renamed:    shellhttpd.disabled/docker-compose.yml -> shellhttpd/docker-compose.yml
        renamed:    shellhttpd.disabled/ -> shellhttpd/

Commit your changes with a message:

git commit -m "shellhttpd: add application"

Push all committed modifications to the remote repository:

git push

The output of git push indicates the start of a new CI job.
