polysquare-travis-container 0.0.47

Description:

polysquaretraviscontainer 0.0.47

Polysquare Travis Container
Creates a self-contained package-management installation, without root access.
This allows you to install a pre-defined set of packages to a directory and
then execute commands using the packages installed in that directory.
Supports Windows, OS X and Linux.
On Windows and OS X, local versions of chocolatey and brew are installed
respectively, with packages installing to the specified folder. Commands
are executed with environment variables set such that the locally
installed packages will be used by any software built or installed
using the psq-travis-container-exec wrapper. Only the host architecture
is supported.
On Linux, proot is used to "containerize" a downloaded
linux distribution, where the package manage operates only on the directory
in which the downloaded linux distribution exists. This allows you to
install packages using apt-get or yum without touching other
system files. proot allow allows for different architectures to be
specified as well, which are emulated transparently using the
qemu-user-mode tool.
For Linux, an alternative 'local' option is also provided which does not
incur the overhead of proot but is not as flexible. Sadly, on Travis-CI,
proot no longer functions correctly and so the latter mode of operation
is required.

Caveats
64 bit executables cannot be emulated on a 32 bit architecture.
Installation
polysquare-travis-container can be installed using using pip from PyPI
Creating a container
Containers can be created with psq-travis-container-create:
usage: psq-travis-container-create [-h] [--distro {Fedora,
Debian,
Ubuntu,
Windows,
OSX}]
[--release RELEASE]
[--arch {ppc,x86_64,x86,arm}]
[--repositories REPOSITORIES]
[--packages PACKAGES]
CONTAINER_DIRECTORY

Create a Travis CI container If an arg is specified in more than one place,
then command-line values override environment variables which override
defaults.

positional arguments:
CONTAINER_DIRECTORY Directory to place container in

optional arguments:
-h, --help show this help message and exit
--distro {Fedora,Debian,Ubuntu,Windows,OSX}
Distribution name to create container of
[env var: CONTAINER_DISTRO]
--release RELEASE Distribution release to create container of
[env var: CONTAINER_RELEASE]
--arch {ppc,x86_64,x86,arm}
Architecture (all architectures other than the
system architecture will be emulated with qemu)
[env var: CONTAINER_ARCH]
--repositories REPOSITORIES
A file containing a list of repositories to add
before installing packages. Special keywords will
control the operation of this file: {release}: The
distribution release (eg, precise) {ubuntu}: Ubuntu
archive URL {launchpad}: Launchpad PPA URL header
(eg, http://ppa.launchpad.net)
--packages PACKAGES A file containing a list of packages to install

The distribution filesystem itself is placed in a subdirectory of
CONTAINER_DIRECTORY, so multiple distribution configurations can be placed in
a single CONTAINER_DIRECTORY. A mini-distribution of proot will also be
placed in CONTAINER_DIRECTORY. This directory should be cached, for instance:
cache:
directories:
- CONTAINER_DIRECTORY

Packages will only be installed if the container is being created and not
restored from the cache. To install additional packages, the travis caches
should be deleted.
Special directories like /tmp and /home are linked automatically, so you
can run binaries or scripts directly from the project root.
Using a container
To run a command inside a container, use psq-travis-container-exec:
usage: psq-travis-container-exec [-h] [--distro {Fedora,
Debian,
Ubuntu,
Windows,
OSX}]
[--release RELEASE]
[--arch {ppc,x86_64,x86,arm}] --cmd
[CMD [CMD ...]]
CONTAINER_DIRECTORY

Use a Travis CI container If an arg is specified in more than one place,
then command-line values override environment variables which override
defaults.

positional arguments:
CONTAINER_DIRECTORY Directory to place container in

optional arguments:
-h, --help show this help message and exit
--distro {Fedora,Debian,Ubuntu,Windows,OSX}
Distribution name to create container of
[env var: CONTAINER_DISTRO]
--release RELEASE Distribution release to create container of
[env var: CONTAINER_RELEASE]
--arch {ppc,x86_64,x86,arm}
Architecture (all architectures other than the
system architecture will be emulated with qemu)
[env var: CONTAINER_ARCH]
-- [CMD [CMD ...]] Command to run inside of container

Executables in CMD are resolved relative to the distribution container, so
running bash would run CONTAINER_DIR/bin/bash and not /bin/bash
inside travis.
The --container, --release and --arch options are used to select a
pre-existing distribution container set up with psq-travis-container-create.
