# Helper script to run the integration tests on a fresh Nextcloud server through
|
||||
# Docker.
|
||||
#
|
||||
# The integration tests are run in its own Docker container; the grandparent
|
||||
# directory of the integration tests directory (that is, the root directory of
|
||||
# the Nextcloud server) is copied to the container and the integration tests are
|
||||
# run inside it; in the container the configuration/data from the original
|
||||
# Nextcloud server is ignored, and a new server installation is performed inside
|
||||
# the container instead. Once the tests end the container is stopped.
|
||||
#
|
||||
# To perform its job, the script requires the "docker" command to be available.
|
||||
#
|
||||
# The Docker Command Line Interface (the "docker" command) requires special
|
||||
# permissions to talk to the Docker daemon, and those permissions are typically
|
||||
# available only to the root user. Please see the Docker documentation to find
|
||||
# out how to give access to a regular user to the Docker daemon:
|
||||
# https://docs.docker.com/engine/installation/linux/linux-postinstall/
|
||||
#
|
||||
# Note, however, that being able to communicate with the Docker daemon is the
|
||||
# same as being able to get root privileges for the system. Therefore, you must
|
||||
# give access to the Docker daemon (and thus run this script as) ONLY to trusted
|
||||
# and secure users:
|
||||
# https://docs.docker.com/engine/security/security/#docker-daemon-attack-surface
|
||||
#
|
||||
# Finally, take into account that this script will automatically remove the
|
||||
# Docker containers named "database-nextcloud-local-test-integration" and
|
||||
# "nextcloud-local-test-integration", even if the script did not create them
|
||||
# (probably you will not have containers nor images with that name, but just in
|
||||
# case).
|
||||
|
||||
# Sets the variables that abstract the differences in command names and options
|
||||
# between operating systems.
|
||||
#
|
||||
# Switches between mktemp on GNU/Linux and gmktemp on macOS.
