The LLVM repos have switched from http to https, and trying to access using http will get redirected to https. Add the apt-transport-https package to the x86 Debian containers that use the LLVM repos, in order to support the https transport method. Note that on Arm we only test with gcc, so don't add the package for the Debian Arm container. This fixes the following error seen on the QEMU smoke tests: E: The method driver /usr/lib/apt/methods/https could not be found.

Docker Containers
These Docker containers should make it possible to build Xen in any of the available environments on any system that supports running Docker. They are organized by distro and tagged with the version of that distro. They are available from the GitLab Container Registry under the Xen project at the registry and can be pulled with Docker from the following path:
docker pull registry.gitlab.com/xen-project/xen/DISTRO:VERSION
To see the list of available containers run make in this
directory. You will have to replace the / with a : to use
them.
Building Xen
From the top level of the source tree it should be possible to run the following:
./automation/scripts/containerize make
Which will cause the top level make to execute within the default
container, which is currently defined as Debian Stretch. Any arguments
specified to the script will be executed within the container from
the default shell.
There are several environment variables which the containerize script understands.
-
CONTAINER: This overrides the container to use. For CentOS 7.2, use:
CONTAINER=centos72 ./automation/scripts/containerize make -
CONTAINER_PATH: This overrides the path that will be available under the
/builddirectory in the container, which is the default path.CONTAINER_PATH=/some/other/path ./automation/scripts/containerize ls -
CONTAINER_ARGS: Allows you to pass extra arguments to Docker when starting the container.
-
CONTAINER_UID0: This specifies whether root is used inside the container.
-
CONTAINER_NO_PULL: If set to 1, the script will not pull from docker hub. This is useful when testing container locally.
-
XEN_CONFIG_EXPERT: If this is defined in your shell it will be automatically passed through to the container.
If your docker host has Linux kernel > 4.11, and you want to use containers that run old glibc (for example, CentOS 6 or SLES11SP4), you may need to add
vsyscall=emulate
to the host kernel command line. That enables a legacy interface that is used by old glibc.
Building a container
There is a makefile to make this process easier. You should be
able to run make DISTRO/VERSION to have Docker build the container
for you. If you define the PUSH environment variable when running the
former make command, it will push the container to the registry if
you have access to do so and have your Docker logged into the registry.
To login you must run docker login registry.gitlab.com. For more
information see the registry help.
