Creating Targets

Let’s simulate regular development on the branch devel. Recall that as you commit changes, it generates Targets tagged with devel. Then all devices following the devel tag receive updates.

Imagine that—while you will keep developing on devel —you want to decide the Target your devices tagged with tutorial will receive.

Hint

On the previous page we tagged the latest devel Target with the additional tag, tutorial.

Now to change the shellhttpd application to create new Target.

Edit docker-compose.yml:

vi shellhttpd/docker-compose.yml

version: '3.2'

services:
  httpd:
    image: hub.foundries.io/<factory>/shellhttpd:latest
    restart: always
    ports:
      - 8080:${PORT-8080}
    environment:
      MSG: "Oi Mundo"

Commit and push the changes:

git status
git add shellhttpd/docker-compose.yml
git commit -m "Update msg"
git push

Go to https://app.foundries.io, select your Factory and click on Targets:

The latest Target named containers-devel should be the CI job you created.

Wait until it finishes and change your application again.

Edit docker-compose.yml:

vi shellhttpd/docker-compose.yml

version: '3.2'

services:
  httpd:
    image: hub.foundries.io/<factory>/shellhttpd:latest
    restart: always
    ports:
      - 8080:${PORT-8080}
    environment:
      MSG: "Hallo Welt"

Commit and push the changes:

git status
git add shellhttpd/docker-compose.yml
git commit -m "Change msg again"
git push

Keep watching your jobs on https://app.foundries.io and once it finishes, change your application one more time.

docker-compose.yml:

vi shellhttpd/docker-compose.yml

shellhttpd/docker-compose.yml:

version: '3.2'

services:
  httpd:
    image: hub.foundries.io/<factory>/shellhttpd:latest
    restart: always
    ports:
      - 8080:${PORT-8080}
    environment:
      MSG: "Howdy world"

Commit and push the changes:

git status
git add shellhttpd/docker-compose.yml
git commit -m "Update msg once again"
git push

You now have three new versions in the Targets version list.

Note

Because your device is now following tutorial, it should not receive updates.
