strato is a package manager and minimal container base image. All packages in strato are created by a simple and containerized build process.

docker run -it rancher/strato
/ # strato add jq

The build instructions for packages are described using a Dockerfile. The package will be built by extracting the files in the final layer from the build process.

As an example, the following Dockerfile builds the GNU make package.

FROM ubuntu
RUN apt-get update && apt-get install -y build-essential pkg-config wget
RUN wget -P /usr/src/ ftp://ftp.gnu.org/gnu/make/make-4.2.1.tar.bz2
RUN cd /usr/src/ && tar xf make*
RUN cd /usr/src/make* \
    && ./configure \
    --prefix=/usr \
    --mandir=/usr/share/man \
    --infodir=/usr/share/info \
    --disable-nls \
    && make

# The following layer is extracted to generate the resulting package
RUN cd /usr/src/make* \
    && make install

All packages are currently built using Ubuntu 16.04 as the base image, but the goal is to eventually have enough packages for strato to be able to build itself.

The base Dockerfiles are in the packages directory in this repository. To build them, you need dapper - from https://github.com/rancher/dapper/releases

Run dapper build-bin to build the binaries in this repo, then build the tarballs using dapper build-packages The tarballs will be in the dist dir - and can then be uploaded to somewhere that you can get to them.

The strato base image includes busybox, glibc, and the strato package manager.
