Running user commands containerized

Running commands containerized

Rarely-used commands do not need to be installed in the workstation or laptop operating system. They can be defined as Dockerfiles and built into container images and used only when needed.

New command is added by:

• Putting sources to a particular subdirectory:

# /usr/local/share/container-sources/svn/Dockerfile
FROM registry.fedoraproject.org/fedora:latest
RUN dnf install -y subversion && dnf clean all
WORKDIR /data
ENTRYPOINT [ "/usr/bin/svn" ]

• For convenience, make a symlink in $PATH

# ln -s build-run-container-sudo /usr/local/bin/svn

• Run the command:

$ svn checkout http://svn.apache.org/repos/asf/httpd/httpd/trunk httpd-trunk

---

Installation

This repository contains build-run-container script which is expected to run as root via sudo. It builds the container image and then executes the command in the container with the identity of the invoking user.

To help with running build-run-container, tiny wrapper build-run-container-sudo which just executes it with sudo is also provided.

So give access to users on the machine to the build-and-run mechanism, sudo needs to be configured, for example with

# /etc/sudoers.d/build-run-container
ALL ALL=(root) NOPASSWD:SETENV: /usr/local/bin/build-run-container

Fix readme

Hi, thanx for talk on Devconf. It looks like you have symlinked readme.md. It doesn't work well on github frontend.
