# Build BNC from sources for multiple operating systems
Docker or podman must be installed on your system, see [Podman Installation Instructions](https://podman.io/getting-started/installation).
The Dockerfiles should work with both commands, docker and podman.
Build example:
```bash
cd to/BNC/root/dir
podman build -t bullseye/bnc:v2.13 -f docker/Dockerfile.bullseye .
```
#### Copy the build artifact from the container
```bash
con=$(podman create )
podman cp $con:/tmp/BNC/bnc bncnew
podman rm $con
```
