Don't auto-switch to root when executing make-container.sh, because auto root switching is also implemented in extra-container. Besides simplifying the code, this is useful for a later commit that introduces flakes-based container building. With this change, the container is built under the regular user instead of root, thereby utilizing the user's regular fetcher and evaluation caches.

|
# Usage:
|
|
#
|
|
# run-tests.sh [--scenario|-s <scenario>] container
|
|
#
|
|
# Start container and start a shell session with helper commands
|
|
# for accessing the container.
|
|
# A short command documentation is printed at the start of the session.
|
|
# The container is destroyed after exiting the shell.
|
|
# An existing container is destroyed before starting.
|
|
#
|
|
# Supported arguments:
|
|
#
|
|
# --destroy|-d to destroy
|
|
#
|
|
# When `run-tests.sh container` from inside an existing shell session,
|
|
# the current container is updated without restarting by switching
|
|
# its NixOS configuration.
|
|
# Use this arg to destroy and restart the container instead.
|
|
#
|
|
# --no-destroy|-n
|
|
#
|
|
# By default, all commands destroy an existing container before starting and,
|
|
# when appropriate, before exiting.
|
|
# This ensures that containers start with no leftover filesystem state from
|
|
# previous runs and that containers don't consume system resources after use.
|
|
# This args disables auto-destructing containers.
|
|
#
|
|
#
|
|
# run-tests.sh container --run c systemctl status bitcoind
|
|
#
|
|
# Run a command in the shell session environmentand exit.
|
|
# Destroy the container afterwards.
|
|
# All arguments following `--run` are used as a command.
|
|
# Supports argument '--no-destroy|-n' (see above for an explanation).
|
|
#
|
|
# Example: Start shell inside container
|
|
# run-tests.sh container --run c
|
|
#
|
|
#
|
|
# run-tests.sh [--scenario|-s <scenario>] container --command|-c
|
|
#
|
|
# Provide a custom extra-container command.
|
|
#
|
|
# Example:
|
|
# run-tests.sh container --command create -s
|
|
# Create and start a container without a shell.
|
|
#
|
|
#
|
|
# All extra args are passed to extra-container (unless --command is used):
|
|
# run-tests.sh container --build-args --builders 'ssh://worker - - 8'
