Hello Debian

This directory contains simple Linux binaries that runs in a Debian container. The Debian container is useful for running binaries that require libc.

There are two example binaries, written in C++ and Rust respectively.

How to run hello_debian

Build and run Fuchsia

Build the workbench_eng.x64 product with this example:

fx set workbench_eng.x64 \
    --with //src/starnix/examples/hello_debian \
    --with //src/starnix/containers/debian

Run this product as usual. For example, by running fx serve in one terminal and ffx emu start --headless --console --net tap in another terminal.

Boot a container

To run a hello_debian component, we first need to boot the debian container:

ffx component resolve core/starnix_runner
ffx component run core/starnix_runner/playground:debian fuchsia-pkg://fuchsia.com/debian#meta/debian_container.cm

You can confirm that this container is running using ffx component list. If everything has gone well, you should see core/starnix_runner/playground:debian running in the system.

Run hello_debian

Create a hello_debian component inside this container:

• C++:

  ffx component create core/starnix_runner/playground:debian/daemons:hello_debian fuchsia-pkg://fuchsia.com/hello_debian_cpp#meta/hello_debian_cpp.cm
  

• Rust:

  ffx component create core/starnix_runner/playground:debian/daemons:hello_debian fuchsia-pkg://fuchsia.com/hello_debian_rust#meta/hello_debian_rust.cm
  

You should see some output similar to the following in ffx log:

[00061.161627][kernels:JNfdNLC][5:5[hello_debian_cpp],stdio,starnix] INFO: hello debian
