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 which 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/cavel/shellhttpd:latest
    restart: always
    ports:
      - 8080:${PORT-8080}
    environment:
      MSG: "This is the TEST 02"

Note that MSG is defined with This is the TEST 02.

Commit and push the changes:

git status
git add shellhttpd/docker-compose.yml
git commit -m "This is the TEST 02"
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 just 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/cavel/shellhttpd:latest
    restart: always
    ports:
      - 8080:${PORT-8080}
    environment:
      MSG: "This is the TEST 03"

Note that MSG is defined with This is the TEST 03.

Commit and push the changes:

git status
git add shellhttpd/docker-compose.yml
git commit -m "This is the TEST 03"
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/cavel/shellhttpd:latest
    restart: always
    ports:
      - 8080:${PORT-8080}
    environment:
      MSG: "This is the TEST 04"

Note that MSG is defined with This is the TEST 04.

Commit and push the changes:

git status
git add shellhttpd/docker-compose.yml
git commit -m "This is the TEST 04"
git push

Finally, you should have three new versions in the Targets version list.

Note

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