At least with Podman it's not possible to call "container rm" on a running container without the force flag. Add the force flag which is also used elsewhere already.

# This script will generate an SDK container image from an SDK tarball
|
|
# (which in turn is generated by bootstrap_sdk[_container]).
|
|
#
|
|
# It uses a number of intermediate build steps:
|
|
# 1. Import the SDK tarball into a "tarball" container image.
|
|
# 2. Build a "plain" SDK container image which creates the "sdk" user
|
|
# and runs "update_chroot" to initialise the x86 and aarch64 SDK cross env.
|
|
# This step uses sdk_lib/Dockerfile.sdk-import.
|
|
# 3. Using the "plain" SDK image, start a temporary "toolchain" container
|
|
# to build toolchain binary packages.
|
|
# 4. Inheriting from the "plain" SDK image and using the toolchain packages,
|
|
# build a "full" SDK container image, with board support for both amd64-usr and arm64-usr.
|
|
# A temporary HTTP server on the Docker interface IP is spun up in this step
|
|
# to serve the toolchain binpkgs to the build container.
|
|
# This step uses sdk_lib/Dockerfile.sdk-build.
|
|
# 5. In a last step, all unnecessary binaries are removed from the "full" image and 3
|
|
# output SDK images are produced:
|
|
# - "all", with both amd64 and arm64 target support, and
|
|
# - "amd64" and "arm64, with only amd64 or arm64 target support respectively.
|
|
# This step uses sdk_lib/Dockerfile.lean-arch.
