-# Test podman-compose with build
-
-```
-podman-compose build
-podman-compose up -d
-curl http://localhost:8080/index.txt
-curl http://localhost:8000/index.txt
-podman inspect my-busybox-httpd2 
-podman-compose down
-```
-
-expected output would be something like
-
-```
-2019-09-03T15:16:38+0000
-ALT buildno=2 port 8000 2019-09-03T15:16:38+0000
-{
-...
-}
-```
-
-as you can see we were able to override buildno to be 2 instead of 1,
-and httpd_port to 8000.
