如何使用来自 cloudfoundry repo 的 apt-buildpack

Question

The apt-buildpack is experimental and not yet intended for production use. I guess that's why also no documentation.

Can you give me example how to push cf-env sample app and install for example rtorrent and/or openvpn . Is it possible to install gnome for testing purposes?

Answer 1

As far as usage goes it's pretty simple, you just need to include an Aptfile in the root directory of your app. That should contain a list of packages to install, one package on each line.

Ex:

$ cat Aptfile
ascii
rtorrent
openvpn

Is telling you that the Apt buildpack only functions to supply binaries. It doesn't actually know how to run your app or any application. For more on the supply script, check out the docs here .

The trick to making it work is that you need to use multi buildpack support. Instructions for doing that can be found here . This should work with most apps, but there's a simple example here .

Once your app stages & starts, you can confirm that your packages were installed by running cf ssh apt-test -t -c "/tmp/lifecycle/launcher /home/vcap/app bash ''" . Anything that was installed should be on the path, but if you want to see where things are installed it'll be under the /home/vcap/deps/<buildpack-number>/ .

That should be about it. Hope that helps!
