Version : 3.1.2

usage:

casa_distro_admin <general options> <command> [<command parameters>...]

general optional arguments:

-v, --verbose: Display as much information as possible.
--version: Display casa-distro version number and exit.
-h, --help: Display help message and exit. If used after command name, display only the help of this command.

Common parameters:¶

Most commands accept more or less the same parameters.

Many subcommands need environment selection specifications: see the documentation on how to specify an environment.

base_directory

default= $HOME/casa_distro

Directory where images and environments are stored. This parameter can be passed on the commandline, or set via the CASA_BASE_DIRECTORY environment variable.

Commands:¶

help¶

Print global help or help about a command.

Parameters¶

format: format help text in a given text format. Valid values are “text” (default) for raw text, or rst (RST/sphinx format).
full: if true or yes or 1, display each subcommand parameters documentation in the general help.

singularity_deb¶

Create a Debian package to install Singularity. Perform the whole installation process from a rw system and Singularity source. Then put the result in a *.deb file.

Parameters¶

dockerhub:

default=ubuntu:20.04

Name of the base image system to pull from DockerHub.

output_dir:

default=/casa/host/src/development/casa-distro/5.1/doc/source

Location of the resulting Debian package file.

version:

default=3.8.3

Version of Singularity to use. This must be a valid release version. Go language is not included in the final package.

create_base_image¶

Create a new virtual image

Creating the casa-system image:

For Singularity you need to run these commands in order to create the casa-system image:
```
cd "$CASA_BASE_DIRECTORY"
singularity pull ubuntu-18.04.sif docker://ubuntu:18.04
```
Then you can directly use the ubuntu image as base for the run image. You may build a “system” image as follows, but it’s not needed:
```
casa_distro_admin create_base_image base=ubuntu-18.04.sif \
    type=system image_version=5.0
```
For VirtualBox:
1. Download a Ubuntu image to your CASA base directory, e.g. lubuntu-22.04.1-desktop-amd64.iso
2. Run create_user_image:
```
casa_distro_admin create_user_image \
    container_type=vbox \
    type=system \
    base=lubuntu-22.04.1-desktop-amd64.iso \
    image_version=5.3
```
3. Follow the instructions that are printed in the terminal to install and configure Lubuntu appropriately.

Parameters¶

type

type of image to publish. Either “system” for a base system image, or “run” for an image used in a user environment, or “dev” for a developer image.

name

default=casa-{type}-{image_version}

If given, select environment by its name. It replaces type, distro, branch and system and is shorter to select one.

base

Source file used to build the image. The default value depends on image type and container type.

output

default=/casa/home/casa_distro/{name}.{extension}

File location where the image is created.

container_type

default=singularity

Type of virtual appliance to use. Either “singularity”, “vbox” or “docker”.

image_version

default=

Version (or branch) of the image

verbose

default=True

Print more detailed information if value is yes, true or 1.

cleanup (effective only if container_type=singularity)

default=yes

If “no”, “false” or “0”, do not cleanup after a failure during image building. This may allow to debug a problem after the failure. For instance, with Singularity one can use a command like:

sudo singularity run --writable
/tmp/rootfs-79744fb2-f3a7-11ea-a080-ce9ed5978945 /bin/bash

force (allowed only if container_type=singularity)

default=no

If yes, true or 1, erase existing image without asking any question.

fakeroot (allowed only if container_type=singularity)

default=yes

If yes, true or 1, use singularity –fakeroot for building the images (this is the recommended wby). Otherwise, “sudo singularity” must be used so singularity has root access on the host.

memory (allowed only if container_type=vbox)

default=8192

Size in MiB of memory allocated for virtual machine.

video_memory (allowed only if container_type=vbox)

default=50

Size in MiB of video memory allocated for virtual machine.

default=131072

For vbox container type only. Size in MiB of maximum disk size of virtual machine.

gui (allowed only if container_type=vbox)

default=no

For vbox container type only. If value is “yes”, “true” or “1”, display VirtualBox window.

publish_base_image¶

create_user_image¶

Create a “user” image given a development environment. The development environment is selected among existing ones its distro and system or simply by its name. Only development environments using the master branch are considered. This command can perform three steps. Each step can be ignored by setting the corresponding option to “no” :

install: perform an installation of the development environment into its installation directory. This modify the development environment by updating its installation directory.
generate: generate a new image for the development environment. The new image is based on base_image and the installation directory of the development environment is copied into the image in /casa/install.

fakeroot (allowed only if container_type=singularity)

default=yes If yes, true or 1, use singularity –fakeroot for building the images (this is the recommended wby). Otherwise, “sudo singularity” must be used so singularity has root access on the host.

base_directory

default= $HOME/casa_distro

Directory where images and environments are stored. This parameter can be passed on the commandline, or set via the CASA_BASE_DIRECTORY environment variable.

install

default=yes If “true”, “yes” or “1”, perform the installation steps: ‘make install-runtime’, as well as ‘make install-doc’ and ‘make install-test’, depending on the install_doc and install_test parameters. If “false”, “no” or “0”, skip all installation steps

install_doc

If “default”, a default list of software will be installed. If starting with “file://”, then the thirdparty install list will be read from a JSON file. Other values are understood as a list of software (“spm12-standalone,freesurfer”). Each will be installed from their host system location into /usr/local on the container image. Software location will be searched in a small search list (/usr/local, /drf/local, /i2bm/local). If installed in another location, this location may be passed after a = sign in the software name, ex: spm12-standalone=/opt/spm,freesurfer. If a JSON file is used, then the file syntax is a dictionary, keys are thirdparty software names (“spm12-standalone”), and values are directories. If default locations are expected, then the value may be null.

generate

default=yes If “true”, “yes” or “1”, perform the image creation step. If “false”, “no” or “0”, skip this step

cleanup

default=yes If “false”, “no” or “0”, do NOT clean up the temp image during the generate step after failed build, can be helpful for debugging

zip

bbi_daily¶

BrainVISA Build infrastructure: daily/nightly automated tests

In BrainVISA Build Infrastructure (BBI), the casa_distro_admin bbi_daily command orchestrates automated builds and tests in a given base directory. The bbi_daily command will run the following steps, while (optionally) logging detailed output to a Jenkins server. See Automated tests with bbi_daily for a complete introduction to automated tests.

Self-update casa_distro using ‘git pull’ and restart itself for the next steps
Select dev environments based on the provided filters (distro, branch, system, image_version, name)
Update casa-dev and casa-run images used by the selected environments to the latest version available from the BrainVISA website
For every selected dev environment, perform the following tasks:
1. bv_maker sources
2. bv_maker configure
3. bv_maker build
4. bv_maker doc
5. perform all tests in the dev environment (running the same commands as bv_maker test)
6. create or update a user image with casa_distro_admin create_user_image (i.e. install the compiled software in a new user image based on the casa-run image, where the software is installed under /casa/install)
7. install that user image into a fresh user environment (reference test data are automatically linked from the dev environment)
8. perform all tests in that user environment

The process can be controlled with the command-line options described below, as well as some configuration keys that can be added to the casa_distro.json of each dev environment:

ctest_options: list of command-line options to pass to ctest on the command-line. ctest is used for listing the tests, so you may pass filtering options to restrict the set of tests being run (e.g. ["-R", "disco"]).
bbi_user_config: an optional dictionary for customizing the creation of a the user image and the user environment, where tests of the user image will be run. This dictionary can contain these keys:
- name: the name of the environment where the user image will be set up. Default: dev_config['name'] + '-userimage'
- directory: the full path where the user environment will be set up. Warning: this directory is erased every time ``bbi_daily`` is run. Default: {base_directory} + name
- image: the full path where the user image will be created. Default: {base_directory} + name + extension
- version: the version string that will be set in the user image, e.g. available as the CASA_VERSION environment variable and as the version metadata key. This value version is passed to time.strftime(). Default: '%Y-%m-%d'.
- setup_commands: list of shell commands that will be run in the newly created user environment. May be used to run post-setup tasks, such as configuring additional files in the home directory of the user (e.g. configuring MATLAB licences…).
